One cup is equal to 14.4375 in^3. If a 1-cup measuring cylinder has a radius of 3 in., what is its height? If

patriot [66]

Answer:

The height of the cup is 0.51 in.

The height of the cup is 4.59 in.

Step-by-step explanation:

The volume of the cylinder is $\pi r^2 h$

Given that,

The volume of the cup is 14.4375 in³.

If the measuring cup has a radius of 3 in.

Then,

$\pi r^2h=14.4375$

Plug r= 3 in.

$\pi (3)^2h=14.4375$

$\Rightarrow h=\frac{14.475}{9\pi }$

⇒h=0.51 in.

The height of the cup is 0.51 in.

If it has radius of 1 in.

Then,

$\pi r^2h=14.4375$

Plug r= 1 in.

$\pi (1)^2h=14.4375$

$\Rightarrow h=\frac{14.475}{1\pi }$

⇒h=4.59 in.

The height of the cup is 4.59 in.

Seth invested n dollars into an investment fund last year. After a period of one year, the value of his investment can be repres

Andre45 [30]

Answer:

A. The value of his investment decreased by 16% during this time period.

Step-by-step explanation:

To answer this problem, suppose an amount n.

After a year in value of the investment is:

$0.84n$

Now we calculate the rate of change of n with the following formula:

$V = \frac{Final\ Amount - Initial\ Amount}{Initial\ Amount}$

$V = \frac{0.84n-n}{n}*100\%\\\\V = \frac{n(0.84-1)}{n}*100\%\\\\V = (0.84-1)*100\%\\\\V = -0.16 * 100\%\\\\V = -16\%$

The value of the investment decreased by 16% with respect to the initial amount.

The correct answer is the option

A. The value of his investment decreased by 16% during this time period.

KiRa [710]

Answer:

Farmer Janet can plant carrots more quickly.

Step-by-step explanation:

If we added 15 more minutes to Farmer Janet's time to equal the same amount as her daughter. We would also have to double the amount of carrots she can plant which totals out to 18 carrots which is 1 more carrot more than her daughter. I hope this helps:)
