Answer:
V = 19.625h
Step-by-step explanation:
Volume of a cylinder V = πr²h
r is the radius
h is the height
Given
r = base/2
r= 5/2
r= 2.5
Substitute into the formula
V = π(2.5)²h
V = 3.14*6.25h
V = 19.625h
hence the required expression is V = 19.625h
Answer:
B
Step-by-step explanation:
The slope of a line is written as a fraction of the vertical distance to the horizontal distance. The line drops down from (0,1) to (4,-2). This is a vertical distance of -3 and a horizontal distance of 4. The slope if the fraction -3/4.
There is a certain order that we follow in doing any mathematical operation:
First we get rid of any operation within brackets, then we do multiplication and divisions and finally we do additions and subtractions.
We need to evaluate: 5x2x(-4) + 6:
So since we have no operations within brackets, then we will do the multiplications first (in their order) then the addition:
5x2x(-4)+6 = 10x(-4)+6 = -40+6 = -34
Now, we need to divide -34 by 2:
-34/2 = -17
The answer is: -17
Answer:
x=9
Step-by-step explanation:
distribute: 3x-6+7=2x+10
add like terms: 3x+1=2x+10
add the x's and the integers: x=9
The largest number in the chart is 45, so the person left 45 minutes after 10:30 a.m. That person left the library at 11:15 a.m.
