The volume of the cone shown is 5 cubic inches. What is the height of a cone with the same base diameter but a volume of 10 cubi

MaRussiya [10]

Answer:

The height of the second cone is 2 h₁.

Step-by-step explanation:

The volume of a cone is:

$V=\pi\ r^{2}\frac{h}{3}$

The volume of the first cone is, V₁ = 5 in³.

The volume of the second cone is, V₂ = 10 in³.

The two cones have the same base diameters.

This implies that the two radii are same, i.e. r₁ = r₂.

Compute the height of the second cone as follows:

$r_{1}=r_{2}$

$\frac{3\cdot V_{1}}{\pi\ h_{1}}=\frac{3\cdot V_{2}}{\pi\ h_{2}}$

$\frac{V_{1}}{h_{1}}=\frac{V_{2}}{ h_{2}}$

$\frac{5}{h_{1}}=\frac{10}{h_{2}}$

$h_{2}=2\ h_{1}$

Thus, the height of the second cone is 2 h₁.

Mr. Jones has 3/4 cup of fertilizer. He will use a 1/8 cup measuring scoop to pour all of the fertilizer onto his plants. How ma

dmitriy555 [2]

Answer:

6 times

Step-by-step explanation:

We will have to divide in order to solve this problem.

$\frac{3}{4}$ ÷ $\frac{1}{8}$

We will have to find the reciprocal of 1/8, which is basically flipping it, so it is 8.

After, we will have to multiply 3/4x8. The product would come out as 24/4, and if you simplify it, the answer will be 6 times.

Emma went to a salon to get her hair cut. The price of the haircut is $65. She wants to leave a 20% tip. What is the total amoun

Murrr4er [49]

Answer:

She should leave a total of $78.

Step-by-step explanation:

To find this, we first need to find the tip amount. We can do this by multiplying the total by the tip percentage.

$65 * 20% = $13

Now that we have that, we need to add it to the cost.

$65 + $13 = $78
