Answer:
x=58
Step-by-step explanation: Since there is a right angle, you add 22 and 10 and get 32. then you subtract from 90, because 90 degrees is what a right angle measures so you should get 58
1. Area: pi x r^2
Radius: 6.9m
Area: 3.14 x 6.9^2
Area: 149.5m
2. Area: pi x r^2
Radius: 150ft
Area: 3.14 x 150^2
Area: 70,650ft
3. Area: pi x r^2
Radius: 8in
Area: 3.14 x 8^2
Area: 200.96in
Area: pi x r^2
Radius: 2in
Area: 3.14 x 2^2
Area: 12.56in
200.96/12.56 = 16
Therefore, it will take 16 4 inch diameter cookies to equal the area of one giant cookie.
For applies= associative and distributive
and for doesnt apply = commutative.
im not 100 sure for the distributive answer but ik the other ones are right
Answer:
Option D) At least 3600
Step-by-step explanation:
We are given the following in the question:
The distribution of scores of individual students on the American College Testing is a bell shaped distribution that is a normal distribution.
Population standard deviation =
We want that the standard deviation of the sample should not be more than 0.1 that is the standard error should not be more than 0.1
Formula for standard error:
Thus, the sample size must be atleast 3600 so that the sample standard deviation is not more than 0.1.
Thus, the correct answer is
Option D) At least 3600
Answer: 400 inches by 10 inches
Step-by-step explanation:
Length of the bridge = 4000feet
Width of the bridge = 100 feet
Since Sue decides that her scale model needs to be 1/10th the size of the real bridge.
If she uses a scale of inches to feet, the dimensions of her model will be:
Length = 4000 × 1/10 = 400 inches
Width = 100 × 1/10 = 10 inches.
Therefore, the dimensions are 400 inches by 10 inches
