It's goofy to subtract perimeter and area; they're in different units. We persist.
The area is 
and the perimeter is 
. so the difference is
Answer: choice A
Answer:
A. 16 m
B. At t = 2 and t = 6
C. 8 seconds
Step-by-step explanation:
Maximum height is at the vertex
(4,16). So maximum height is 16 m at t = 4
The rocket is at a height of 12m at two distinct times:
At 2 seconds and again at 6 seconds
The rocket is in air when the height is not zero, I.e between t=0 and t=8
8-0 = 8 seconds
D is your answer because you gave 20 and they are subtracting the cost of 3x lbs of apples
Hey there! I'm happy to help!
We want to see how many times bigger 2/5 is than 9/10. Let's call how much bigger 2/5 is b and solve below.
9/10b=2/5 (2/5 is b times larger than 9/10)
We divide both sides by 9/10, so your division would be 2/5÷9/10.
b=4/9
Therefore, the builder worked 4/9 times as long in the morning as he did in the afternoon.
Have a wonderful day! :D
