Using the pairs (1,32) and (2,64) the rate of speed is (64-32 / 2-1 = 32 feet per second.
To find the rate of decent you would multiply the rate by time:
The equation is y = 32x
B. Replace x with 15 and solve for y:
Y = 32(15)
Y = 480
The rate of speed is 480 feet per second.
Answer:
140%
Step-by-step explanation:
28-10 = 14 person enrolled
14/10 = 140%
Answer:
2/3
Step-by-step explanation:
3y = 2x
Divide each side by 3
3y/3 = 2x/3
y = 2/3 x
The direct variation relationship is
y = kx
In this case k = 2/3
The answer in scientific notation is: 4.32 x 10^-2
2k = 25
Divide 2 on each side
k = 12.5
Each pizza would cost $12.50
Hope this helps!
