Answer:
The answer is number three
Step-by-step explanation:
I know this because the formula for pythageon theorm is. (A)squared + (B)squared = (C)squared so if you substitude the value of number three into the therom it would be equal to this 6x6+8x8=10x10
then if you simplify it would equal 36 + 64 = 100 and so this would satisfy the therom.

Three students have summer jobs. The proportional relationship between their pay and the hours they work is shown.
Student A:
Time (hours) 5 14
Pay (dollars) 58.75 164.50
Student B: $162.00 for 12 hours
Student C: The equation p = 14.5h, where p represents total pay and h represents hours worked
Which student is paid the most for 20 hours of work?
Student A, who is paid $270 for 20 hours of work
Student B, who is paid $235 for 20 hours of work
Student C, who is paid $290 for 20 hours of work
All three students are paid $235 for 20 hours of work
PLS HURRY AND THANK YOU
Answer:
C. Student C, who is paid $290 for 20 hours of work
Step-by-step explanation:
What we know:
- Student A ( 164.50 = 14 hours )
- Student B ( 162.00 = 12 hours
- Student C ( 14.50h = p )
What we need to figure out:
- How much each person makes per hour ( Pt.1 )
- Who will make the most in 20 hours ( Pt.2 )
How to execute:
- Divide for A & B
- Convert for C
- Multiply for all
Step 1: Divide the total pay by the hours for A & B
Student A: 164.50 ÷ 14 = 11.75 per hour ( Found PT.1 )
Student B: 162.00 ÷ 12 = 13.50 per hour ( Found PT.1 )
Step 2: Convert C so that it looks like A & B
Student C: 14.5(h) = p ---> p ÷ h = 14.5 per hour ( Found PT.1 )
Step 3: Multiply the hourly rate by the 20 hours
Student A: 11.75 × 20 = 235 for 20 hours ( Found PT.2 )
Student B: 13.50 × 20 = 270 for 20 hours ( Found PT.2 )
Student C: 14.50 × 20 = 290 for 20 hours ( Found PT.2 )

how do you find common multiples and factors explain
Answer:
We can find the common multiples of two or more numbers by listing the multiples of each number and then finding their common multiples. For example, to find the common multiples of 3 and 4, we list their multiples and then find their common multiples. Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, ...
Assume that the carrying capacity for the US population is 800 million. Use it and the fact that the population was 282 million in 2000 to formulate a logistic model for the US population. (Let t = 0 correspond to the year 2000. Use k for your constant.) P (t) = ____ millions
(t) = 326millions. The logistic model for the US population would be:
P(t) = 800 / (1 + e^(-k(t-2000)))
Where P(t) is the population in millions at time t (measured in years after 2000), k is the growth rate constant, and e is the base of the natural logarithm.
Using the fact that the population was 282 million in 2000, we can solve for k:
282 = 800 / (1 + e^(-k(0-2000)))
282(1 + e^(-k(2000))) = 800
1 + e^(-k(2000)) = 2.83687943
e^(-k(2000)) = 1.83687943
-k(2000) = ln(1.83687943)
k = -ln(1.83687943) / 2000
k ≈ 0.0071
Now we can plug in the value of k to get the logistic model for the US population:
P(t) = 800 / (1 + e^(-0.0071(t-2000)))
So, for example, the population in 2020 (t = 20) would be:
P(20) = 800 / (1 + e^(-0.0071(20-2000))) ≈ 326 million

what is the sum of all interior angles of a parallelogram
identify all of the necessary assumptions for a significance test for comparing dependent means.
When performing a significance-test for comparing dependent means, several assumptions are necessary to make a valid inference- Normality, Equal variances, Independence,Random-sampling.
Some of these assumptions are:
Normality: The distribution of differences between the paired observations must be approximately normal.
This can be assessed using a normal probability plot or by conducting a normality test.
Equal variances: The variances of the paired differences should be approximately equal.
This can be assessed using the Levene's test.
Independence: The paired differences should be independent of each other.
This means that each observation in one sample should not influence the corresponding observation in the other sample.
Random sampling: The observations should be selected randomly from the population of interest.
This ensures that the sample is representative of the population.

if the area of a parallelogram is 23/42 inches to the power of 2, and the height is 1/6 in, write an equation that relates the height, base, and area of the parallelogram?
By answering the presented question, we may conclude that (1/7) × 23 parallelograms inches x (1/6) inches Equals 23/42 inches to the power of 2
What is parallelograms?In Euclidean geometry, a parallelogram is a simple quadrilateral with two sets of parallel sides. A parallelogram is a kind of quadrilateral in which both sets of opposite sides are parallel and equal. Parallelograms are classified into four types, three of which are unique. The four distinct shapes are parallelograms, squares, rectangles, and rhombuses. A quadrilateral is a parallelogram when it has two sets of parallel sides. The opposing sides and angles of a parallelogram are both the same length. The internal angles on the same side of the horizontal line are also angles. The total number of internal angles is 360.
Let's start with the formula for parallelogram area:
Base x Height = Area
We know that the parallelogram's height is 1/6 inch and its area is 23/42 inch to the power of 2. So, by plugging these values into the formula, we get:
23/42 inches multiplied by 2 Equals base x 1/6 inch
6 x 23/42 inches multiplied by 2 = base
(6/42) x 23 inches multiplied by 2 = base
base = (1/7) x 23 inches
Base x Height = Area
(1/7) × 23 inches x (1/6) inches Equals 23/42 inches to the power of 2

A group of 5 high school students are hanging out on a weekend evening watching a season of a popular sitcom. Even though when asked individually none of them find the script particularly entertaining they are all laughing after every joke. What might explain this
In the given case, the fact that even if students individually did not find the script particularly entertaining they are all laughing after every joke when they watched as a group can be explained by social facilitation, social norms, and contagious nature of laughter.
A group of 5 high school students are hanging out on a weekend evening watching a season of a popular sitcom. Even though when asked individually none of them find the script particularly entertaining they are all laughing after every joke.
One possible explanation that could account for this phenomenon is called social facilitation. It is a social psychological concept that refers to the tendency for the presence of others to enhance an individual's performance on a given task or activity.
In the case of the high school students watching the sitcom, they may be experiencing social facilitation because they are watching it in a group. The presence of others is making the experience more enjoyable and they are feeding off each other's reactions, which makes it even more entertaining.
In addition, the students may be conforming to social norms and behaving in a way that is expected of them. Laughter is often seen as a socially appropriate response to jokes, even if they are not particularly funny. Therefore, the students may be laughing simply because they feel it is what they are supposed to do when watching a comedy with friends.
Finally, the students may be experiencing the contagious nature of laughter. When people hear others laughing, it can trigger a response in their own brain that makes them more likely to laugh as well. This could be happening among the group of high school students as they watch the sitcom together.

Lucy has to run two errands. She starts from home and travels 3 miles south to the post office. From the post office, she travels 4 miles east to the gas station. Then, from the gas station, she travels 5 miles to return home. The entire trip forms a triangle. What was the smallest angle made in her trip?
Answer:
Smallest angle = \(36.87^\circ\)
Step-by-step explanation:
Given that:
Let the home be at the point A.
Lucy travels 3 miles south to reach point B.
Then 4 miles to east to reach point C and then
returns to home traveling 5 miles making it a triangle for the whole journey.
This travel is nothing but forms a right angled \(\triangle ABC\), right angled at point B.
To find:
Smallest angle in the travel.
Solution:
In a triangle, the smallest angle is the angle opposite to the smallest side.
Therefore, the \(\angle C\) will be the smallest.
We can use tangent trigonometric ratio here:
\(tan\theta = \dfrac{Perpendicular}{Base}\)
\(tan C = \dfrac{AB}{BC}\\\Rightarrow tan C = \dfrac{3}{4}\\\Rightarrow \angle C=tan^{-1}{0.75}\\\Rightarrow \angle C=36.87^\circ\)
Therefore, the answer is:
Smallest angle = \(36.87^\circ\)

What is point slope form of line?
The equation of a straight line that passes through a given point and is inclined at a specific angle to the x-axis can be found using the point slope form.
One of the formulas used to determine a line's equation is the point slope formula. According to the point slope formula, y - y1 = m (x - x1) is the equation for a line with slope "m" and the points (x, y1) on it.
We have to find the equation of line that passes through the points (6, 5) and (0, -7).
First to find the slope of the line,
\(m = \frac{y_2-y_1}{x_2-x_1} = \frac{-7-5}{0-6}= \frac{-12}{-6} = 2\)
Now, consider the point slope form of the line
\(y-y_1=m(x-x_1)\)
Plug \(m = 2, (x_1, y_1) = (0, -7)\)
⇒
\(y-(-7)=2(x-0)\\y+7=2x\\y=2x-7\)
Hence, the equation of line that passes through the points (6, 5) and
(0, -7) is y = 2x - 7.

Sam took 93 minutes to drive from Manchester to Sheffield . a) Work out Sam's average speed for his total drive from Liverpool to Sheffield .
Using the relation between velocity, distance and time, it is found that Sam's average speed for his total drive from Liverpool to Sheffield is of 52 km/h.
Velocity is distance divided by time, that is:
\(v = \frac{d}{t}\)
From Liverpool to Manchester, he drove 56 km, with an average speed of 80 km/h, hence, the time, in hours, was of:
\(t = \frac{d}{v} = \frac{56}{80} = 0.7\)
From Manchester to Sheffield, 61 km, considering a time, in hours, of \(\frac{93}{60} = 1.55\)
Hence, for the entire trip(Liverpool to Sheffield), 56 km + 61 km in 0.7 + 1.55 hours, hence:
\(v = \frac{56 + 61}{0.7 + 1.55} = 52\)
