Answer:
Step-by-step explanation:
V= π(8)^2(12/3)
V= 64(4)π
V= 256π
V= 804.3 cm^3
You need to add the dollar sign so it will look like $0.50 or you could put $.50

Step-by-step explanation: multiply length by width by height and you get 143184.
Answer:
C
Step-by-step explanation:
(c) x + 2y = 7
This equation os linear one but has two variables ( x and y)
a) The function that represent this situation is y = 90 + 8x.
b) His weight be after 8 weeks is 154 lbs.
<u>Step-by-step explanation:</u>
It is given that,
- He started at 90 kilograms.
- And gained weight at a constant rate of 8 lbs a week.
a) Write a function to represent this situation. Use x and y as your variables.
- Let 'x' be the number of weeks he gained weight.
- Let 'y' be the total weight.
Hence the equation can be framed as,
Total weight = starting weight + weight gained in x weeks.
We know that, each week he gains 8 lbs. Therefore, for 8 weeks he gained 8x lbs of weight.
⇒ y = 90 + 8x.
∴ The function that represent this situation is y = 90 + 8x.
b) What would his weight be after 8 weeks?
To find his week after 8 weeks, substitute x=8 in the function y = 90 + 8x.
⇒ 90 + 8(8)
⇒ 90 + 64
⇒ 154 lbs.
∴ His weight be after 8 weeks is 154 lbs.
