what is the height of this cone?
Answers
Answer:
height is = 3/2 ft
Step-by-step explanation:
a cones volume can be represented by 1/3(h)(pi)(r^2)
we must go backwards to find this question out
if the diameter is 2/3 then the radius is 1/3
then you must square that
that is 1/3 * 1/3 which is 1/9
1/9(1/3)(pi)(h) is 1/18(pi)
we can remove pi from both sides and multiply the 1/9 and the 1/3
1/27(h) = 1/18
we must find the lcm or least common multiple to figure this out
the lcm is 54
1/27 is essentially 2/54 and 1/18 is 3/54
2/54(h) = 3/54
we can multiply each side by 54
2h = 3
divide 2 on both sides
h is 3/2

m - 13 = 24
A. Subtract 13 from both sides
B. Add 24 to both sides
C. Add 13 to both sides
D. Divide by 13 on both sides
Answers
Answer:
C. Add 13 to both sides of the equation.
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, m. Add 13 to both sides of the equation:
m - 13 = 24
m - 13 (+13) = 24 (+13)
m = 24 + 13
m = 37

What is the sale price for a beach umbrella with a regular price of $43.59 which is on sale for 20% off?
Answers
Answer:
$34.87
Step-by-step explanation:
20% of $43.59
[tex]\frac{20}{100} X \frac{43.59}{1}[/tex] = [tex]\frac{1}{5} X \frac{43.59}{1}[/tex] = [tex]\frac{43.59}{5}[/tex] = $8.718
Therefore the price is, $43.59 - $8.718 = $34.87
Answer:
The answer is $34.87
Step-by-step explanation:
$43.59- 8.72=$34.87
20% of $43.59 is $8.72
So, your answer will be $34.87
$43.59- 8.72=$34.87
