Answer:
866
Step-by-step explanation:
She could add the hundreds first: 400+400=800
Then the tens: 50+10=60
Then the ones: 0+6=6
And add them all up: 800+60+6=866
52.5
Explanation:
x/18. 30/100 cross multiply 30*18=5250
5250 divided by 100= 52.5
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.
