Answer
Part A
None of the expressions given is the answer. The answer is w=V/(l*h)
PART B
w=8cm
Step-by-step explanation:
Part A
From the formula given to calculate the volume, we have to isolate the with w:
PART B
We know the formula to calculate with from Part A. Next, we replace given values in the formula.
w=V/(l*h)
w=120/(5*3)
w=120/15
w=8 cm
Answer: LAST OPTION
Step-by-step explanation:
The formula for calculate the volume of a cone is:
Where r is the radius and h is the height.
The formula for calculate the volume of a cylinder is:
Where r is the radius and h is the height.
As you can see, the difference between the the formulas is that <em>r²hπ</em> of the cone is divided by 3. Therefore, if you know the volume of the cone and you know that cylinder has the same base and height as the cone, you have to multiply the volume of the cone by 3.
Therefore, the result is:
Fraction: 26/3
Decimal: 8.6
Q = d - 12
q = 28 - d
d - 12 = 28 - d
d + d = 28 + 12
2d = 40
d = 40/2
d = 20 <== 20 dimes
q = d - 12
q = 20 - 12
q = 8 <== 8 quarters
