The interior angle of a regular polygon is equal to each other since all sides of the polygon are congruent. The formula that expresses the relation of the sides of the polygon and the measurement of the interior angle is (n2)*180/n where n is 7. Each interior angle then measures 128.6 degrees.
If the input value is negative, the output value is always positive. We know this because the negative sign before the 4z will always reverse the negativity of the number that is plugged in.
Answer:
<u>It's expected that Jason make 16 out of 20 free throws</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Jason's free-throw scoring average = 80%
2. In a recent game Jason attempted 20 free throws. How many free throws would you expect him to make?
Free throws expected to make by Jason = 20 * 80%
<u>Free throws expected to make by Jason = 16</u>
Answer:
The two numbers are 29 and 18
Step-by-step explanation:
Let x and y be the two numbers
x = 2y-7
x+y = 47
We have two equations and 2 unknowns
Substituting the first equation into the second equation
2y-7+y = 47
Combine like terms
3y -7 = 47
3y-7+7 = 47+7
3y = 54
Divide by 3
3y/3 = 54/3
y = 18
Now find x
x = 2y-7
x = 2*18 -7
x = 36-7
x = 29
The two numbers are 29 and 18
