Answer:

x=2.25

Step-by-step explanation:

ΔABC and ΔADE are similar.

∴ sides are proportional.

$\frac{5}{1} =\frac{x+9}{x} \\5=\frac{x}{x} +\frac{9}{x} \\5=1+\frac{9}{x}\\\frac{9}{x}=5-1\\\frac{9}{x}=4\\x=\frac{9}{4}=2.25$

What is the volume of a right circular cone if the circumference of the base is 125.6 ft and the height is 75 ft.?

Eddi Din [679]

Answer:

Hence the volume of the cone is 31384.52 cubic feet

Step-by-step explanation:

We must first need to understand how the volume of a cone is calculated.

It is simply calculated by multiplying the base area of the cone by the height, and dividing the result by 3.

This is :

Volume of cone = $\frac{\pi r^2 h}{3}$

we are not given the base area of the cone. However, we are given the circumference from which we can get the radius of the base.

Circumference =

$2 \pi r=125.6ft\\r =125.6/2 \pi=19.99ft$

hence the volume of the cone is

$\frac{\pi (19.99)^2 75}{3}=31384.52ft^{3}$

Hence the volume of the cone is 31384.52 cubic feet

Tony spent $60.54 and bought 3 packs of notebooks and a calculator. How much does a pack of notebooks cost if a calculator costs

statuscvo [17]

Well, if the notebooks cost x, then you know that
3x + 45.87 = 60.54
right? so, solve for x. 60.54 - 45.87 = 14.67
Divide the difference by 3.

Calculate.<br> 6P6<br> Note: Pr =<br> n!<br> (n-r)!<br> (Hint: 0!= 1)<br> Enter

kvasek [131]

The value of $^6P_6$ is 720

<h3>How to solve the expression?</h3>

The expression is given as:

$^6P_6$

The permutation formula is:

$^nP_r = \frac{n!}{(n - r)!}$

So, we have:

$^nP_r = \frac{6!}{(6 - 6)!}$

Evaluate the difference

$^nP_r = \frac{6!}{0!}$

0! = 1.

So, we have:

$^nP_r = 6!$

Evaluate the factorial

$^6P_6 = 720$

Hence, the value of $^6P_6$ is 720
