Answer:32
Step-by-step explanation:96-64=32 half of 64 is 32 also equal to 50%
First you find the area of the semi circle. The semi circle would be considered a Sector Area of a circle. The formula to find that is (π(radius²)(given angle)) divided by 360. Assuming the semi circle goes across the width of the rectangle, it would be half of that measure. So 8 would be the radius. And the given angle would be 180 because it’s a semi circle. You just plug that formula into ur calculator and get the answer 235.5in²
Answer:
x=25
Step-by-step explanation:
Assuming you meant 3x = 75 what you want to do is isolate x. To isolate x you want to work backward. Since it is 3 times x you want to divide each side by 3 to get x on its own.
(3x)/3 = (75)/3
When you divide 3 and 3 you get one. 1x is represented by just an x so x=25.
Answer:
20
Step-by-step explanation:
( x − 2 ) 2 − 16 Set y equal to the new right side. y = ( x − 2 ) 2 − 16 Use the vertex form, y = a ( x − h ) 2 + k , to determine the values of a , h , and k . a = 1 h = 2 k = − 16 Find the vertex ( h , k ) . ( 2 , − 16 )
