Answer:
2.11 sec
Step-by-step explanation:
Given that the ball is thrown from a height of 80 feet
it follows the equation
when the ball hits the ground the height if the ball is equal to 0
The equation shown above does not show the substitution property. Instead, it shows the Addition Property of Equation where 3 is added to both of its sides. This is shown below,
4x - 3 = 7
4x - 3 + 3 = 7 + 3
4x = 10
Answer:
9 pi
Step-by-step explanation:
First find the circumference of the circle
C =2 * pi *r
C = 2 * pi *9
C = 18 pi
This is a semicircle which is 1/2 of a circle
Take 1/2 of the circumference
1/2 C = 1/2 ( 18 pi)
1/2 C = 9 pi
The population before the increase was 894.
STEP 1:
put numbers in order from lowest to highest
517, 517, 565, 627, 714, 728, 867, 961
STEP 2:
find the difference between the lowest and highest numbers
961 - 517= 444 ft^2 range
ANSWER: The range of the areas is 444 ft^2.
Hope this helps! :)
