△MNO ~△DEF. Identify the perimeter and area of △MNO to the nearest tenth. PLEASE HELP!!!
Answer: P =38.7 in, A=63.7in^2
Step-by-step explanation: start by using the formula for area of a triangle: A =bh/2 and plug in values given for the larger triangle to find the height. 115=9h/2,. 230 =9h h= 25.556
Subtract from perimeter to get an estimate of the third side: 62-34.556=27.45
Realize now that the drawing is not to scale!
Use the dimensions of the larger triangle to and the proportion 6.7/9 = smaller / larger to find other dimensions of the smaller triangle. Add the sides to get perimeter. Multiply bh/2 to get the Area. Choose the answer that is closest to your calculations as the numbers are estimated. We cannot assume that this is a right triangle.

Key: 2 | 1 | 0 means 12 for Bay Side and 10 for Seaside
Part A: Calculate the measures of center. Show all work. (2 points)
Part B: Calculate the measures of variability. Show all work. (1 point)
Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)
PLEASE HELP ASAP !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Part A: To calculate the measures of center, we can find the median and the mean for each school.
For Bay Side School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 25, so the median class size is 25.
To find the mean class size for Bay Side School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 12 + 12 + 12 + 14 + 15 + 15 + 16 + 16 + 18 + 18 + 20 + 20 + 23 + 25 + 25 = 243. There are 15 classes, so the mean class size is 243/15 ≈ 16.2.
For Seaside School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 15, so the median class size is 15.
To find the mean class size for Seaside School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 10 + 10 + 10 + 11 + 12 + 15 + 15 + 16 + 17 + 17Part A (continued):
18 + 18 + 20 + 20 + 25 = 222. There are 14 classes, so the mean class size is 222/14 ≈ 15.9.
Therefore, the measures of center for Bay Side School are: median = 25, mean ≈ 16.2.
The measures of center for Seaside School are: median = 15, mean ≈ 15.9.
Part B: To calculate the measures of variability, we can find the range and the interquartile range (IQR) for each school.
For Bay Side School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 12, so the range is 25 - 12 = 13.
To find the IQR for Bay Side School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 15 and Q3 is 20. Therefore, the IQR is 20 - 15 = 5.
For Seaside School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 10, so the range is 25 - 10 = 15.
To find the IQRPart B (continued): for Seaside School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 12 and Q3 is 18. Therefore, the IQR is 18 - 12 = 6.
Therefore, the measures of variability for Bay Side School are: range = 13, IQR = 5.
The measures of variability for Seaside School are: range = 15, IQR = 6.
Part C: If you are interested in a smaller class size, Seaside School is a better choice because its measures of center are lower than those of Bay Side School, indicating that its class sizes tend to be smaller on average. Additionally, Seaside School has a smaller range and IQR, indicating less variability in class size. Therefore, there is less chance of encountering very large classes at Seaside School compared to Bay Side School.
Find the sum by first finding the equivalent fractions so that both of the fractions have common denominators.

Make a perspective drawing of the following figure by using the top, side and front
views as shown. (5 points)
Answer:
The shape really appears in my mind as exactly as the side shows. From the top, it would appear to be a square, first of all because no shadows, and because the slant is facing up. From the front, it would be the exact same thing as I just described. Only from the side can you see that it's a square, wedge triangle.
I have provided an example of this explanation in visual terms, based on the image you provided. I tried to draw it in 3D, but I'm just not a really great artist, so I hope you can make out what I was trying to depict ;)

The area of the circle is 9/64π square units. The radius of a circle is blank units. The circumference of the circle is blank units.
*One radius and one circumference*
a. 9/32
b. 3/8
c. 3/4
d. 9/32π
e. 3/8π
f. 3/4π
Answer:
C = 2π(3/8) = 3π/4 units
Step-by-step explanation: The area of the circle is given by the formula A = πr^2, where A is the area and r is the radius.Therefore, 9/64π = πr^2Simplifying, we get:r^2 = 9/64Taking the square root of both sides, we get:r = 3/8The circumference of a circle is given by the formula C = 2πr, where C is the circumference and r is the radius.Therefore, the circumference of the circle is:C = 2π(3/8) = 3π/4 units
Malia gave the cashier $50 to pay for 5 pizzas. The cashier gave her $1.75 in change. Each pizza cost the same amount. What is the cost in dollars and cents for each pizza?
Answer:
$9.65
Step-by-step explanation:
Subtract the total amount from the change
50 - 1.75 = 48.25
Divide the resulting amount by the amount of pizzas
= 48.25/5
Simplify
= $9.65
Answer: $9.65 I know some one already answered this question but I want to answer also lol

George drove 240 miles to his grandmother's house. The graph below shows the relationship between the distance he traveled and time. What does the slope of the graph represent? A. George's speed in minutes per mile. B. The total distance he has traveled. C. The total distance he has left to travel. D. George's speed in miles per minute.
Answer:
D. George's speed in miles per minute.
Step-by-step explanation:
This answer is quite confusing because A. and D. are very similar but here is my reasoning.
The slope of the line is 1.
So B. and C. isn't right because they didn't travel 1 mile and they don't have 1 mile left to drive.
Now it is between A. and D. (1 minute per mile and 1 mile per minute)
When talking about speed the distance comes first (Ex. 20 miles per hour), so the best answer is D.

Nine friends went on a camping trip a campsite costs 40 per night for the first 4 people and campers can pay an extra fee for each additional person if the group of friends rented one campsite for one night and paid 80 how much did the campground charge for each additional person
Answer:
8 dollars per extra person
Step-by-step explanation:
subtract the original 40 dollars from 80 ,you get 40,the probloem tells you that there is 9 people meaning there was 5 extras ,so 40/5=8
Answer:
$8 charge for each additional person
Step-by-step explanation
$40/night for each person
First 4 people already paid.
Leftover are 5 people.
9-4=5
Since first 4 people paid, the rest to be paid is $40.
$80-$40=$40
To find the charge for each person, divide the amount of money left by the amount of people left.
40÷5= 8
$8 is the additional charge for each additional person.

The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143
