Answer:
Here's what i know:
x + y = 23
3y / 20 =x
Here we can use substitution to help find our answer:
y + 3y/20 = 23
20y/20 + 3y/20 = 23
23y/20 = 23
23y = 23 * 20
y = 23 * 20 / 23
y = 20
x + 20 = 23
x = 3
The general form would be:

where 'a' is responsible for the magnitude of the function, 'b' is responsible for horizontal shift.and 'c' is responsible for vertical shift of the function.
Your answer would be:

Looks like choice A
To find the area of the slice of pie, you will represent the part of the pie as 37/360 because this is the fractional part that was cut. Multiply this by the total area of the circle to get the area of this one slice.
A = 37/360 x pi x r^2
37/360 x 3.14 x 17.5^2
A = 98.8 square feet
The approximate area of the slice was 98.8 square feet. That is one big pie!!
Answer:
16.81
Step-by-step explanation:
P = 4a.
then the length of a side is 16.4 /4 = 4.1.
A = a * a = 4.1 * 4.1 = 16.81
The answer would be 92 over 63(92/63) since the least common denominator is 63
