Step-by-step explanation:

He starts 17 and 1/2 feet off the ground

Elevation relative to ground: 17 1/2

Then he increases the height by 4 and 3/4

Expression: 17 1/2 +4 3/4

Elevation relative to ground: 22 1/4

Next he decreases the elevation by 15.8 feet

Expression: 22.25-15.8

Elevation relative to ground: 6.45

Kameryn types 75 words per minute and is just starting to write a term paper. Joe already has 510 words written and types at a s

AnnZ [28]

Answer:

Kameryn will have more words typed than Joe when the number of minutes exceeds 34.

Step-by-step explanation:

Let

x -----> the number of minutes

y ----> the total words typed

we know that

Kameryn

$y=75x$ -----> equation A

Joe

$y=60x+510$ -----> equation B

Solve the system of equations by substitution

Substitute equation A in equation B and solve for x

$75x=60x+510$

$75x-60x=510$

$15x=510$

$x=34\ minutes$

That means

For x=34 minutes

The amount of words written by Kameryn and Joe are the same.

therefore

For x > 34 minutes

Kameryn will have more words typed than Joe when the number of minutes exceeds 34.

What is the volume in cubic centimeters of a right circular cone with radius 2 centimeters and height 9 centimeters?

andreev551 [17]

Answer:

$V = 37.7cm^3$

Step-by-step explanation:

The formula for the volume of a cone is:

$V = \frac{1}{3} \pi r^2h$

Given:

- Radius = 2cm

- Height = 9cm

Let's plug these into the equation:

$V = \frac{1}{3} \pi (2)^2(9)$

Now solve:

$V = \frac{1}{3} \pi (4)(9)\\V = \frac{1}{3}\pi 36\\V = \frac{36}{3} \pi \\V = 12\pi \\V = 37.7cm^3$

Therefore, the volume of the cone is 37.7cm^3.

I hope this helps!!
