205.1000 is greater than 0.205
Answer:
R V
1 9π in³
2 36π in³
3 81π in³
Step-by-step explanation:
For, r = 1
V = π(1)²9 = 9π in³
For, r = 2
V = π(2)²9 = 4*9π in³ = 36π in³
For r = 3
V = π(3)²9 = 9*9π in³ = 81π in
R V
1 9π in³
2 36π in³
3 81π in³
Answer:
48
Step-by-step explanation:
80/100=0.8

Answer:
It will take her 3 hours to read 120 pages.
Step-by-step explanation:
The number of pages read(y) after x hour can be modeled by a linear function in the following format:

In which a is the number of pages read per hour and b is the initial number of pages read.
A straight line goes through (0, 0)
This means that when 
So



(0.5, 20)
When 
So




The function in:

According to the graph, which statement must be true?
It will take her 2 hours to read 60 pages.

Less than 2 hours for 60 pages, so this is false.
It will take her 3 hours to read 120 pages.

This statement is true.
It will take her 4 hours to read 180 pages.

More than 4 hours to read 180 pages. So false.
It will take her 5 hours to read 210 pages.

More than 5 hours to read 210 pages. So false.
Easy. The answer would be 4 1/8.
