4. If mZRST = (12x - 1)º, mZRSU = (9x - 15),
and mZUST = 53°, find each measure.
x=
mZRST =
mZRSU =
Answer:
mZRST = 155°, mZRSU = 102°
Step-by-step explanation:
Given that mZRST = (12x - 1)º, mZRSU = (9x - 15), and mZUST = 53°.
We know that mZRSU + mZUST = mZRST (since S is a common point)
So, (9x - 15)º + 53° = (12x - 1)º
Expanding the brackets we have
9x - 15 + 53 = 12x - 1
collecting like terms, we have
53 - 15 + 1 = 12x - 9x
54 - 15 = 3x
39 = 3x
Dividing through by 3, we have
x = 39/3
x = 13°
So, mZRST = (12x - 1)º
= 12(13) - 1
= 156 - 1
= 155°
So, mZRST = 155°
mZRSU = (9x - 15),
= 9(13) - 15
= 117 - 15
= 102°
So, mZRSU = 102°
At a particular restaurant, each slider has 225 calories and each chicken wing has 70 calories. A combination meal with sliders and chicken wings has a total of 10 sliders and chicken wings altogether and contains 1165 calories. Write a system of equations that could be used to determine the number of sliders in the combination meal and the number of chicken wings in the combination meal. Define the variables that you use to write the system. Do not solve the system.
x+y=10
225x+70y=1165 where x represents the quantity of sliders in the combo.
The quantity of chicken wings in the combo is given by y.
What is equation?An equation is an expression of one or more variables equated to a constant or another expression. Equations are used in mathematics to describe the relationship between two or more variables and often involve operations such as addition, subtraction, multiplication, division, and exponents. Equations can also be used to describe physical phenomena and other phenomena such as chemical reactions, motion, and electricity.
Let x represent the number of sliders in the combination meal and let y represent the number of chicken wings in the combination meal. The system of equations used to determine the number of sliders and chicken wings in the combination meal is given by:
Equation 1: 225x + 70y = 1165
Equation 2: x + y = 10
This system of equations can be used to find the number of sliders and chicken wings in the combination meal. To solve this system, the equations must be manipulated to isolate one of the variables. For example, if we subtract 70y from both sides of Equation 1, we obtain 225x = 1165 - 70y. We can then divide both sides by 225 to obtain x = (1165 - 70y)/225. This expression can then be substituted into Equation 2 to obtain a single equation in one variable.
Therefore, the system of equations given by Equation 1 and Equation 2 can be used to determine the number of sliders and chicken wings in the combination meal.

let $a,b$ be the points on the coordinate plane with coordinates $(t-4,-1)$ and $(-2,t 3)$, respectively. the square of the distance between the midpoint of $\overline{ab}$ and an endpoint of $\overline{ab}$ is equal to $t^2/2$. what is the value of $t$
The midpoint \(m\) of \(\overline{ab}\) has coordinates
\(\left(\dfrac{(t-4) + (-2)}2, \dfrac{-1 + (t+3)}2\right) = \left(\dfrac{t-6}2, \dfrac{t+2}2\right)\)
The distance from \(m\) to \(a\) is
\(\sqrt{\left((t-4) - \dfrac{t-6}2\right)^2 + \left(-1 - \dfrac{t+2}2\right)^2} = \sqrt{\left(\dfrac{t-2}2\right)^2 + \left(-\dfrac{t+4}2\right)^2} = \sqrt{\dfrac{t^2}2+t+5}\)
If this is equal to \(\frac{t^2}2\), then we solve for \(t\).
\(\sqrt{\dfrac{t^2}2 + t + 5} = \dfrac{t^2}2\)
\(\left(\sqrt{\dfrac{t^2}2 + t + 5}\right)^2 = \left(\dfrac{t^2}2\right)^2\)
\(\dfrac{t^2}2 + t + 5 = \dfrac{t^4}4\)
\(\dfrac{t^4}4 - \dfrac{t^2}2 - t - 5 = 0\)
\(t^4 - 2t^2 - 4t - 20 = 0\)

Rocky Mountain Tire Center sells 10,000 go-cart tires per year. The ordering cost for each order is $35, and the holding cost is 40% of the purchase price of the tires per year. The purchase price is $25 per tire if fewer than 200 tires are ordered,$17 per tire if 200 or more, but fewer than 8,000, tires are ordered, and $13 per tire if 8,000 or more tires are ordered.
a) How many tires should Rocky Mountain order each time it places an order?
b) What is the total cost of this policy?
a) Rocky Mountain should order 200 tires each time it places an order.
b) The total cost of this policy is $17,160.
a) To determine how many tires Rocky Mountain should order each time, we need to consider the different price levels and find the point where it is most cost-effective to order. Let's analyze the three price levels:
If fewer than 200 tires are ordered: The purchase price is $25 per tire.
If 200 or more, but fewer than 8,000 tires are ordered: The purchase price is $17 per tire.
If 8,000 or more tires are ordered: The purchase price is $13 per tire.
Since the ordering cost is $35 per order, it is most cost-effective to order the maximum quantity that falls within the second price level, which is 200 tires.
b) To calculate the total cost of this policy, we need to consider the ordering cost and the holding cost. The holding cost is 40% of the purchase price per tire per year. Let's calculate the total cost:
Total holding cost = (Purchase price per tire * Quantity ordered * Holding cost rate) / 2 = (($17 * 10,000 * 0.4) / 2) + (($13 * 2,000 * 0.4) / 2) = $34,000 + $5,200 = $39,200
Total cost = Total ordering cost + Total holding cost = (Ordering cost per order * Number of orders) + Total holding cost = ($35 * (10,000 / 200)) + $39,200 = $1,750 + $39,200 = $40,950
Therefore, the total cost of this policy is $40,950.
Rocky Mountain Tire Center should order 200 tires each time it places an order, resulting in a total cost of $40,950 for this policy. This ordering quantity and cost analysis allows Rocky Mountain to make efficient and cost-effective decisions in managing their inventory.

Check your work algebraically. If you can please help before tomorrow that would be gratefully appreciated. Thank you in advance!
The number of flashlights purchased is 4.
The number of alkaline D batteries purchased is 12.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 9 is an equation.
We have,
Cost of a flashlight x = $5.50
Cost of a batterie y = $4
Number of items = 16
Total cost = $82
We can make two equations.
x + y = 16 _____(1)
x = 16 - y ______(2)
5.50x + 4y = 82________(3)
Putting (2) in (3) we get,
5.50(16 - y) + 4y = 82
88 - 5.50y + 4y = 82
5.50y - 4y = 88 - 82
0.50y = 6
y = 6/0.50
y = 12
Putting y = 12 in (2) we get,
x = 16 - 12
x = 4
We can cross-check.
x + y = 16
12 + 4 = 16
16 = 16
Thus,
The number of flashlights is 4.
The number of alkaline D batteries is 12.

Sammy wrote the following proof. What did he do wrong?
While solving the proof, Sammy made a mistake as option b), he assumed secθ = 1/sinθ but secθ = 1/cosθ
Here we see that in the first line, Sammy writes
cos²θ . tan²θ = cos²θ(sec²θ -1)
This is definitely correct as 1 + tan²θ = sec²θ
Now, in the next line, he expanded the expression by solving the brackets to get
cos²θ . tan²θ = cos²θ . sec²θ - cos²θ
Now, he changes the sec²θ expression. We know that,
secθ = 1/cosθ
Hence, sec²θ = 1/cos²θ
But, Sammy wrote, 1/sin²θ, hence he was wrong here.
Therefore, the correct proof will be
cos²θ . tan²θ = cos²θ/cos²θ - cos²θ
or, cos²θ . tan²θ = 1 - cos²θ
= sin²θ
Hence Sammy assumed secθ = 1/sinθ but secθ = 1/cosθ and made a mistake

Victor, a recent high school student, took the sat exam, then the probability (given as a percentage) is 53.8%
Let's start defining the random variable X.
X : '' SAT critical reading scores from the 2019 school year for high school students in the United States ''
We know that X ~ N (μ,σ)
Where μ is the mean and σ is the standard deviation.
⇒ X ~ N (497,115)
If we want to calculate probabilities related to X we need to standardized the random variable. We do this by subtracting the mean to X and then dividing by the standard deviation. This new random variable will be ''Z'' and Z ~ N (0,1)
We can find the probabilities of ''Z'' in any standard normal table.
The cumulative distribution of ''Z'' is the function Φ where :
P ( Z ≤ a ) = Φ (a)
Now, we need to calculate the following probability :
= P ( 120 < \(X\) < 513 )
If we standardized this :
= P ( \(\frac{120-497}{115}\) < \(\frac{X-497}{115}\) < \(\frac{513-497}{115}\) )
We know that \(\frac{X-497}{115}\)≅ Z ⇒
= P ( \(\frac{120-497}{115}\) < \(Z\) < \(\frac{513-497}{115}\) )
= P ( \(\frac{120-497}{115}\) < \(Z\) < \(\frac{513-497}{115}\) )
= P ( -3.27 < \(Z\) < 0.139 )
= Φ(-3.27) - Φ(0.139)
= 0.9898 - 0.4509
= 0.5389

what is the equation of the line that is perpendicular to line m and passes through the point (3,2)
The equation of the line that is perpendicular to line m and passes through the point (3, 2) is y = (2/5)x + 4/5.
How to Find the Equation of Perpendicular Lines?To find the equation of a line that is perpendicular to line m, we need to know the slope of line m.
The slope of line m can be found using the two given points on the line, (0, -3) and (-2, 2):
slope of line m = (change in y) / (change in x) = (2 - (-3)) / (-2 - 0) = 5 / (-2) = -5/2
A line perpendicular to m will have a slope that is the negative reciprocal of -5/2. The negative reciprocal is obtained by flipping the fraction and changing its sign.
slope of line perpendicular to m = -1 / (-5/2) = 2/5
Now we have the slope of the line perpendicular to m and a point that it passes through, (3, 2). We can use the point-slope form of the equation of a line to find its equation:
y - y1 = m(x - x1), where (x1, y1) is the given point and m is the slope.
Substituting in the values we have:
y - 2 = (2/5)(x - 3)
Simplifying:
y - 2 = (2/5)x - (6/5)
y = (2/5)x - (6/5) + 2
y = (2/5)x + 4/5

By determining the value of x when y = 0, (x, 0), and the value of y when x = 0, respectively, the x-intercept and y-intercept are determined (0, y).
What is linear equation?A two-variable equation with a line-shaped graph is referred to as a linear equation. A collection of coordinate plane points that are all the solutions to the linear equation make up the graph. If all of the variables have true numerical values, the equation can be graphed by first drawing a sufficient number of points to identify a pattern, then connecting those points to include all of the points.
A linear equation is represented in standard form as
Ax+By=C,A,B≠0
The equation for y must first be solved before you may graph a linear equation in its usual form.
The x-intercept is found by finding the value of x when y = 0, (x, 0), and the y-intercept is found by finding the value of y when x = 0, (0, y).

D.1 Give an estimate for the total volume of food and water you've ingested in the last day, in milliliters. D.2 How many times larger is the amount of blood your heart has pumped in the last day than the amount of food and drink you took in? D.3 How much error do you expect in your answer to 4 b ? You should give an quantitative response to this, but not one generated by a formula. Instead, estimate the error by examining how closely you think you know the values you estimated for food intake and blood flow. You don't need to use advanced error propagation; an approximate response is fine. D.4 What is the relevance of this calculation to the theory that all the blood that flows through your veins is generated in the liver?
An estimate for the total volume of food and water you've ingested in the last day is 3000-5000 milliliters. On average, the heart pumps about 5 liters of blood per minute. 10-20% or more error I'm expecting. Calculating heart blood volume compared to food and drink consumption is crucial for understanding circulation and liver function.
D.1 Estimating the amount of food and water consumed in a day can be difficult without specific measurements, but a rough estimate can be made based on typical intake amounts. On average, a person may consume 2-3 liters of water and 1000-2000 calories per day, resulting in an estimated total volume of 3000-5000 milliliters.
D.2 The amount of blood pumped by the heart varies from person to person and depends on factors such as heart rate and overall health. On average, the heart pumps about 5 liters of blood per minute, which is much larger than the estimated volume of food and water intake.
D.3 Estimating food and water intake and blood flow is prone to error due to variability and uncertainties in personal measurements. Individuals' habits, health, and physical activity levels can affect these estimates, potentially resulting in a significant error of 10-20% or more.
D.4 The calculation of the heart's blood volume compared to food and drink consumption is crucial for understanding the circulation system and liver role.
The liver processes nutrients, detoxifies, and produces blood components, while the heart is responsible for circulating blood throughout the body. The vast difference in volume between the two is emphasized, emphasizing the heart's crucial role in maintaining circulation.

Solve for points!!!!
Answer:
To solve for b in the equation:
(b + 15)/6 = 4
We can start by multiplying both sides by 6 to eliminate the fraction:
(b + 15)/6 * 6 = 4 * 6
Simplifying the left side by canceling out the 6's:
b + 15 = 24
Then, we can isolate b by subtracting 15 from both sides:
b + 15 - 15 = 24 - 15
Simplifying the left side by canceling out the 15's:
b = 9
Therefore, the solution is:
b = 9
The seeds in bush bean pods are each the product of an independent fertilization event. Green seed color is dominant to white seed color in bush beans. If a heterozygous plant with green seeds self-fertilizes, what is the probability that 6 seeds in a single pod of the progeny plant will consist o 5 green and 1 white seeds
The probability of getting 5 green seeds and 1 white seed in a single pod is 0.25 or 25%.
In bush beans, green seed color is dominant to white seed color. If a heterozygous plant with green seeds (Gg) self-fertilizes, we can use the principles of Mendelian genetics to determine the probability of obtaining 6 seeds in a single pod with 5 green and 1 white seed.
When the plant self-fertilizes, each seed in the pod receives one allele from the mother plant (G) and one allele from the father plant (g). Since the plant is heterozygous (Gg), there are two possible combinations of alleles that can result in a white seed: Gg or gg. The probability of getting a white seed is equal to the probability of inheriting the gg combination.
To calculate the probability, we can use a Punnett square. When a heterozygous plant self-fertilizes, the Punnett square shows that there is a 25% chance (1 out of 4 possible combinations) of obtaining a white seed (gg). Therefore, the probability of getting 5 green seeds and 1 white seed in a single pod is 0.25 or 25%.
It is important to note that this probability assumes that the inheritance of seed color follows Mendelian genetics and that there are no other factors influencing the expression of seed color in bush beans.

Step-by-step explanation:
linda, clare and jane had a total of 116 dolls together. linda received 15 dolls from clare and jane gave 13 dolls to linda. by the end, the ratio of dolls linda and clare had was 3:4 and the ratio of jane and clare was 2:3. find the original number of dolls each girl owned.
The original number of dolls each girl owned is Linda = 8, Clare = 63, and Jane 45.
What is a Ratio?A ratio indicates the number of times one number contains another.
Given that, the total number of dolls is 116.
Let Linda, Clare, and jane have L, C, and J dolls respectively.
Now, Linda received 15 dolls from Clare, which can be represented as:
L + 15 and C - 15
Since Jane gave 13 dolls to Linda, the expression becomes:
L + 15 + 13, C - 15, J - 13
Or, L + 28, C - 15, J - 13
Now, the ratios are:
L + 28 : C - 15 = 3 : 4
J - 13 : C - 15 = 2 : 3
Rewrite the ratios after multiplying the first ratio by 3 and the second ratio by 4:
L + 28 : C - 15 = 9 : 12
J - 13 : C - 15 = 8 : 12
The ratio of all three is:
L + 28 : C - 15 : J - 13
9 : 12 : 8
Note that the number of total dolls is still 116, therefore,
9 + 12 + 8 = 116
29 = 116
1 = 4
Hence, 1 unit is equivalent to 4 dolls.
The value of 9 is:
9 ×4 = 36
Hence,
L + 28 = 36
L = 8
Similarly,
C - 15 = 12 × 4
C - 15 = 48
C = 63
And,
J - 13 = 8×4
J - 13 = 32
J = 45
Hence, the original number of dolls each girl owned is Linda = 8, Clare = 63, and Jane 45.

Assume that there is a statistically significant bivariate relationship between the amount of texting during driving and the number of accidents. Scientists later investigate whether or not this bivariate relationship is moderated by age.
Age 16-20: r = 0.6 p = 0.01
Age 21+: r = 0.2 p = 0.05
T or F: Based only on the r and p values listed above you can come to the conclusion that age is a moderator of the bivariate relationship between the amount of texting and the number of accidents.
It is False that based only on the r and p values listed above you can come to the conclusion that age is a moderator of the bivariate relationship between the amount of texting and the number of accidents.
In the given scenario, it is not completely true that based only on the r and p values listed above, you can come to the conclusion that age is a moderator of the bivariate relationship between the amount of texting and the number of accidents.
Let's first understand what is meant by the term "moderator.
"Moderator: A moderator variable is a variable that changes the strength of a connection between two variables. If there is a statistically significant bivariate relationship between the amount of texting during driving and the number of accidents, scientists investigate whether this bivariate relationship is moderated by age.
Therefore, based on the values of r and p, it is difficult to determine if age is a moderator of the bivariate relationship between the amount of texting and the number of accidents.
As we have to analyze other factors also to determine whether the age is a moderator or not, such as the sample size, the effect size, and other aspects to draw a meaningful conclusion.
So, it is False that based only on the r and p values listed above you can come to the conclusion that age is a moderator of the bivariate relationship between the amount of texting and the number of accidents.
