If its perimeter, it should be quite easy to find. Just add 12+9+15. Which equals 36. So the perimeter is 36 inches. -Hope it helps!

Hi there! P=L+W+H. It really doesn't matter what the length, width, and height is when your dealing with perimeter. In this case, the length is 12 inches, the width is 9 inches and the height is 15 inches. 12 inches+9inches+15inches=36 inches. Therefore, the answer is 36 inches.

A bag contains 15 marbles. The probability of randomly selecting a green marble is One-fifth. The probability of randomly select

dsp73

Given:

Total number of marbles = 15

Probability of randomly selecting a green marble = $\dfrac{1}{5}$ .

Probability of randomly selecting a green marble, replacing it, and then randomly selecting a blue marble = $\dfrac{2}{25}$ .

To find:

The number of blue marbles.

Solution:

Let the number of blue marbles be x.

$\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}$

$P(Blue)=\dfrac{x}{15}$

It is given that,

$P(Green)=\dfrac{1}{5}$

Probability of randomly selecting a green marble, replacing it, and then randomly selecting a blue marble is $\dfrac{2}{25}$ . So,

$P(Green)\times P(Blue)=\dfrac{2}{25}$

$\dfrac{1}{5}\times \dfrac{x}{15}=\dfrac{2}{25}$

$\dfrac{x}{75}=\dfrac{2}{25}$

Multiply both sides by 75.

$\dfrac{x}{75}\times 75=\dfrac{2}{25}\times 75$

$x=2\times 3$

$x=6$

Therefore, the number of blue marbles in the bag is 6.

Find the exact value of tan(pi/12) using the sum and difference formulas

kari74 [83]

Π/12 is half of π/6, which is 30 degree
tan(α/2)=(1-cosα)/sinα)
plug in the values: tan(π/12)=(1-cosπ/6)/sin(π/6)=(1-√3/2)/(1/2)=2-√3

The volume of a cylinder is 400x cm. The radius of the base of the cylinder is 4 cm. What is the height of the cylinder

irina1246 [14]

Answer: 8cm

Step-by-step explanation:

$V=\pi r^2h$

Solve for h;

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

$h=\frac{400cm^3}{(3.14)(4cm)^2}$

$h=7.96\\h=8$
