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
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

Someone solve this please?
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

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.

Estimate by rounding each mixed number to thenearest whole number 5 1/3 - 3 7/9
Answer:
1.6 or 2?
Step-by-step explanation:
5-3 =2
1/3 - 7/9 LCD
3/9 - 7/9 =-4/9
2-4/9 = 1 5/9
16/3-34/9 LCD
1 5/9 = 1.5555555555 rounded is 1.6 or 2? Not sure if decimals count.

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 :)

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.
