Step-by-step explanation:
Part 1 of 2:
(a) The equation that describes Winona's total take-home pay, P, in terms of the number of hours, x, worked at the first job and the number of hours, y, worked at the second job can be written as:
P = (10x) + (9.25y + 0.7 * 9.25y) - 0.2[(10x) + (9.25y + 0.7 * 9.25y)]
Simplifying the equation:
P = 10x + 9.25y + 0.7 * 9.25y - 0.2(10x + 9.25y + 0.7 * 9.25y)
Part 2 of 2:
(b) If Winona is committed to working 30 hours per week at the first job, let's assume x = 30. We need to find the number of hours per week, y, she would need to work at the second job to reach a biweekly take-home pay of $800.
Using the simplified equation from part (a), we substitute x = 30 and solve for y:
800 = (10 * 30) + (9.25y + 0.7 * 9.25y) - 0.2[(10 * 30) + (9.25y + 0.7 * 9.25y)]
800 = 300 + (9.25y + 0.7 * 9.25y) - 0.2(300 + (9.25y + 0.7 * 9.25y))
Now, we can solve for y:
800 = 300 + 9.25y + 0.7 * 9.25y - 0.2(300 + 9.25y + 0.7 * 9.25y)
Simplify the equation:
800 = 300 + 9.25y + 0.7 * 9.25y - 0.2 * 300 - 0.2 * 9.25y - 0.2 * 0.7 * 9.25y
Combine like terms:
800 = 300 - 60 + 9.25y - 1.85y - 0.1295y
800 = 240 + 7.32y
Subtract 240 from both sides:
560 = 7.32y
Divide both sides by 7.32:
y ≈ 76.5
Therefore, Winona would need to work approximately 76.5 hours per week at her second job to reach a biweekly take-home pay of $800.

10. Higher Order Thinking Each of 5 friends has x action figures in
his or her collection. Each friend buys 11 more action figures. Now
the 5 friends have a total of 120 action figures.
a. Write an equation that models the problem.
b. Solve the equation to find the number of action figures, x, that
each friend had originally.
Each friend had originally 13 action figures before buying 11 more.
Given that there are 5 friends and each of them has x action figures in his or her collection. When they buy 11 more action figures, the total number of action figures they will have is 120.
a) We need to find an equation that models the problem. Let x be the original number of action figures that each friend had.
Therefore, the total number of action figures that each friend will have after purchasing 11 more is x + 11.
The total number of action figures will be 5(x + 11) = 5x + 55.
Now, according to the problem,5x + 55 = 120
This is our equation that models the problem.
b) We have to solve the equation 5x + 55 = 120 to find the original number of action figures, x, that each friend had before buying 11 more action figures.
5x + 55 = 120
5x = 120 - 55 (subtract 55 from both sides)
5x = 65x = 13
Therefore, each friend had originally 13 action figures before buying 11 more.

millimeters. Determine the total number of color-wheel size combinations.
(This is probability and I’m having such a hell of a time figuring it out pls help)
There are a total of 8 color-wheel size combinations for the kickboard scooter. This means that customers have 8 different options to choose from when selecting the color and wheel size for their scooter.
To determine the total number of color-wheel size combinations for the kickboard scooter, we need to multiply the number of color options by the number of wheel size options.
Given that there are 4 color options (silver, red, blue, and purple) and 2 wheel size options (125mm and 180mm), we can use the multiplication principle to find the total number of combinations:
Total combinations = Number of color options × Number of wheel size options
Total combinations = 4 colors × 2 wheel sizes
Total combinations = 8

Answer:
The width and length of the rectangle are \(22\) and \(16+x\), for \(x > -16\), respectively.
Step-by-step explanation:
From Geometry, we remember that area of the rectangle (\(A\)) is defined by:
\(A = w\cdot l\) (1)
Where:
\(w\) - Width.
\(l\) - Length.
In addition, we know that area is described by a first-order polynomial:
\(A = 352+22\cdot x\) (2)
Meaning that is the product of another first-order polynomial and a constant. That is:
\(A = a\cdot (b+c\cdot x)\) (3)
Now we determine the Great Common Divisor of 352 and 22:
\(352 = 2\times 2\times 2 \times 2 \times 2 \times 11\)
\(22 = 2\times 11\)
The Great Common Divisor is 22.
Then, the area of the rectangle can be expressed by this expression:
\(A = 22\cdot (16+x)\) (3b)
According to this, the width and length of the rectangle are \(22\) and \(16+x\), for \(x > -16\), respectively.
Farmer Elentire started with 71 dubbles on his farm. Every month, he
got 6 more of them. Farmer Hopt started with 10 dubbles on her farm.
Every month, she purchased 10 more of them.
Write a system of equations, in slope-intercept form, to model each
farmer's dubbles (y) as months (x) increase.
y= 71+ 6x
y= 10+ 10x
What pair of numbers solves the system? Use values accurate to the
nearest tenth.
The pair of numbers that solves the system is (15.25, 164.5).
The system of equations, in slope-intercept form, for Farmer Elentire and Farmer Hopt are:
y = 6x + 71 (for Farmer Elentire)
y = 10x + 10 (for Farmer Hopt)
To find the pair of numbers that solves the system, we need to find the point where the two lines intersect.
We can do this by setting the equations equal to each other:
6x + 71 = 10x + 10
Solving for x, we get:
4x = 61
x = 15.25
Now that we know x = 15.25, we can plug this value into either equation to find y.
71 + 6x = 10 + 10x
Subtracting 6x and 10 from both sides, we get:
61 = 4x
Dividing both sides by 4, we get:
x = 15.25
Now we can use either of the original equations to find y. Let's use the first equation:
y = 71 + 6x = 71 + 6(15.25) ≈ 164.5
Using the first equation, we get:
y = 6(15.25) + 71
y = 163.5
Therefore,
The pair of numbers that solves the system is (15.25, 163.5), accurate to the nearest tenth.

A tower on a college campus was built with a faulty foundation and is starting to lean. A student climbs to the tilted top and drops a rope down to the ground. The
end of the rope lands 3 feet from the base of the tower and measures 57 feet from
the top of the building to the ground. What is the angle that the tower is leaning?
Round your answer to the nearest degree, and enter the number only
Answer:
leaning at 3 degrees off of normal (to the nearest whole degree)
Step-by-step explanation:
To visualize, let's assume the tower is leaning to the right, (as viewed by us).
If the rope is dropped from the top to the ground, the tower, the rope and the ground (between the rope and the tower) form a right triangle.
The height and base of the triangle are given
Often we're looking for the angle near the ground, but here, we're looking for the angle between the rope and the tower because the angle is congruent to the angle that the tower forms with it's original vertical position (alternate interior angles). If the tower was standing straight up and hadn't been leaning at all, we wouldn't say that the tower was leaning 90°... we would say it was leaning 0°. Whereas if the tower fell over and was laying flat on the ground, we would say it was leaning at 90°. So, we're not measuring the angle between the tower and the ground, but rather the angle between the tower where it should be, and where it is... which is the same angle as the rope forms with the tower.
Recall that \(tan(\theta)=\dfrac {opp}{hyp}\)
Since we know the two legs of the right triangle, one can setup a tangent relationship with the two legs, but remember that the "opposite" side is going to be the ground, and the "adjacent side" will be the rope.
\(tan(\theta)=\dfrac {ground}{rope}\\tan(\theta)=\dfrac {3ft}{57ft}\\tan(\theta)=\frac {3}{57}\\\theta=tan^{-1}(\frac {3}{57})\\\theta=3.012787504^o\\\theta \approx 3^o\\\)

Natalie is selling fruit at the Saturday market. She has a
otal of 48 pears that she wants to sell. She makes bags of
pears and sells them for $5 per bag. In which equation
oes b represent the number of bags of pears?
If Natalie puts 4 pears in each bag, she will be able to sell a total of 12 bags of pears at the Saturday market.
To represent the number of bags of pears, b, that Natalie sells at the Saturday market, we can use the following equation:
b = total_number_of_pears / pears_per_bag
In this equation, "total_number_of_pears" represents the total quantity of pears Natalie has, and "pears_per_bag" represents the number of pears she puts in each bag.
Given that Natalie has a total of 48 pears, we can substitute the value into the equation:
b = 48 / pears_per_bag
Now, we need to determine the number of pears she puts in each bag. The information provided states that Natalie sells bags of pears, and each bag is sold for $5. However, the specific number of pears per bag is not given. To proceed, we need this information.
Let's assume that Natalie puts 4 pears in each bag. We can substitute this value into the equation:
b = 48 / 4
Simplifying the equation gives:
b = 12
So, if Natalie puts 4 pears in each bag, she will be able to sell a total of 12 bags of pears at the Saturday market.
It's important to note that the specific value of "pears_per_bag" will affect the final result. If Natalie puts a different number of pears in each bag, the equation will yield a different number of bags sold.

In a lottery, the top cash prize was $632million, going to three lucky winners. Players pick four different numbers from 1 to 57 and one number from 1 to 44. A player wins a minimum award of $100 by correctly matching two numbers drawn from the white balls (1 through 57) and matching the number on the gold ball (1 through 44). What is the probability of winning the minimum award?
The probability of winning the minimum award of $100 in the lottery is \(\frac{113}{140448}\)
The probability of picking first winning number (out of 57 white balls) is \(\frac{1}{57}\)
Now, out of the remaining 56 white balls, the probability of picking second winning number is \(\frac{1}{56}\)
So total probability of the correctly matching two numbers drawn from the white balls is \(\frac{1}{57} + \frac{1}{56}\)
Next, to match the winning number on the gold ball, probability of this event is \(\frac{1}{44}\)
Thus overall probability of winning the minimum award is calculated by multiplying the individual probabilities of aforesaid two independent events as follows:
\((\frac{1}{44}) (\frac{1}{57}+\frac{1}{56})\)
= \(\frac{113}{140448}\)
Above value is the probability of winning the minimum award of $100.

[(4r²t)³]²
Answer:
To solve the expression [(4r²t)³]², you need to follow the order of operations (PEMDAS):
Calculate the expression inside the outermost parenthesis first: (4r²t)³ = (4 * r^2 * t)^3, where r and t are variables.
Raise the result to the power of 3: (4 * r^2 * t)^3 = 64 * r^6 * t^3.
Raise the result to the power of 2: (64 * r^6 * t^3)^2 = 4096 * r^12 * t^6.
So, [(4r²t)³]² = 4096 * r^12 * t^6.

F(x) = x^3 and G(x) = (4x)^3 − 5
so
G(x) = F(4x) -5
the visual effect is
1) shrink horizontally by 1/4
2) shift down by 5
therefore
the answer is the option
D.The graph of G(x) is the graph of F(x) compressed horizontally and shifted 5 units down.
