I’m pretty positive the answer is option three, one over twenty-five. Mainly because every second increased is 25ft higher from the ground.
Answer:
22
Step-by-step explanation:
mean is calculated as
mean = 
Given the mean of 12 numbers is 20 , then
= 20 ( multiply both sides by 12 )
sum = 240
Given the mean of 8 numbers is 25 , then
= 25 ( multiply both sides by 8 )
sum = 200
Total sum of the 20 numbers = 240 + 200 = 440, then mean of 20 numbers is
mean = 
= 22
What you do is 8 x 8 x 8 and cube your number
=512
Answer:
D. *6F
Step-by-step explanation:
C=(F-32)*5/9
30=(F-32)*5/9
F = (30*9)/5+32
F = 86
4(-2y + 16) + 8y = 32
-8y + 64 + 8y = 32
64 = 32
