20% of the middle school students decided not to go skiing. How many middle school students are there if 40 stayed in the lodge?
Write a proportion for the situation.
Solve the problem. Show your work.
Answer:
Step-by-step explanation:
s(20/100)=40
20s=4000
s=200
So there are a total of 200 students.
Answer:
There are 200 middle school students
Step-by-step explanation:
The equation for this question can be: 40 is 20% of what. This can be simplified to 40 = 0.2x and then to get x by itself you divide 40 by 0.2 which is 200.

Compare the areas. What is the ratio of the areas? SHOW YOUR WORK
Answer:
Ratio of the area of MIKE to TEAM = 9 : 1
Step-by-step explanation:
Ratio of similar shapes = square of the ratio of their corresponding sides
Since TEAM ~ MIKE, therefore the ratio of their areas = square of the height of MIKE : square of the height of TEAM
Ratio = 33² : 11²
Ratio = 1089 : 121
Ratio = 9 : 1
Dont know this question I am 2nd grade math 2 quarters = how many coins
Answer:
Well, 2 quarters are 2 coins. But, if you are asking the value of 2 quarters, then your answer will be, 50.
Step-by-step explanation:
So, 1 quarter = 25 cents. So that means that, 25 x 2 or 25 + 25 = 50. So, your answer will be 50. Hope that helps! :)
Answer:50
Step-by-step explanation:if a quarter equals 25cents and you have 2 quarters,you have to add .25+25 that equals 50 this is a simple way to do it.
Can you guys help plsssss I’m tireddddd
Answer:
#8 - 52°, #9 - 29°
Step-by-step explanation:
8. The two angles added together are a straight line, so they sum up to 180 degrees.
x + (2x + 24°) = 3x + 24° = 180°
3x + 24° = 180°
3x = 156°
x = 52°
9. Similar to #8. "Supplementary" means they add up to 180° (whether they are actually next to each other or not).
So, 4x + (2x + 6°) = 180°
6x + 6° = 180°
6x = 174°
x = 29°
Hope this helps. Get some rest. Zzzzz :)

Solve for x in the figure below
Answer:
x = 20
Step-by-step explanation:
5x - 21 = 2x + 39 (corresponding angles are congruent)
Collect like terms
5x - 2x = 21 + 39
3x = 60
Divide both sides by 3
3x/3 = 60/3
x = 20

A marketing research firm wishes to determine if the adult men in Laramie, Wyoming, would be interested in a new upscale men’s clothing store. From a list of all residential addresses in Laramie, the firm selects a simple random sample of 100 and mails a brief questionnaire to each. What is the population of interest?
Answer:
The population of interest is composed by all mean that live in Laramie.
Step-by-step explanation:
Sampling
This is a common statistics practice, when we want to study something from a population, we find a sample of this population.
For example:
I want to estimate the proportion of New York state residents who are Buffalo Bills fans. So i ask, lets say, 1000 randomly selected New York state residents whether they are Buffalo Bills fans, and expand this to the entire population of New York State residents.
In this question:
Sample of 100 men from Laramie. This means that the population of interest is composed by all mean that live in Laramie.

Answer:
y = 4
Step-by-step explanation:
The perimeter of a polygon is the distance around the polygon. This can be found by adding up all of the side lengths. In this problem, one is given an expression for the perimeter and an expression for each side length. Using the formula for the perimeter, one can substitute in all of the given expressions and solve for the vairable.
(4y + 5) + (3y + 2) + (4y + 5) + (3y + 2) = 58 + 3y
Simplify,
4y + 5 + 3y + 2 + 4y + 5 + 3y + 2 = 58 + 3y
14y + 14 = 58 + 3y
Inverse operations,
14y + 14 = 58 + 3y
-3y -3y
11y + 14 = 58
-14 -14
11y = 44
/11 /11
y = 4
