Answer: 3900\pi ft^3

if you use the formula on how to find the volume of a cone

V=\pir^2*h/3

you will insert 30 where the r is, 13 in where h is, after you just solve that and your answer would be 3900\pi ft^3

A playstation 5 is $900 and costs $50 per game. A xbox is $400 and costs $60 per game. How many games will it take for both cons
belka [17]

Answer:

It would take a PlayStation 5 and 2 games to equal an Xbox and 10 games.

Step-by-step explanation:

I made a list that increase in the increments of the game price.

Something like this:

900—400~consoles alone

950—460~1 game

1000–520~2 games

1050—580~3 games

1100—640~4 games

1150—700~5 games

1200—760~6 games

1250—820~7 games

1300—880~8 games

1350—940~9 games

1400—1000~10 games

Left side is PlayStation 5 and right side is Xbox. The first row is the price of the consoles alone and then each row after that is the price of the console with an additional game. As you can see, the third row down on the left, the PlayStation 5 with 2 games is $1,000. If you look at the eleventh row on the right, you can see that Xbox with 10 games is also $1,000

Leland was able to build 1/4 of a shelf in 2/3 of an hour. How many shelves can he build per hour?​
Gre4nikov [31]

Answer:

7/20 of one shelf in an hour

Step-by-step explanation:

if you think about the problem in numbers out of 100, we know that

- 2/3 of an hour is 40 minutes per hour because 60/3 = 20

- 1/4 of a shelf is 25% of the shelf

In an hour Leland can build 35% of a shelf in an hour or 7/20 of a shelf

Richard simplified an expression in three steps, as shown:
soldi70 [24.7K]

Answer:

Step 2 because Richard multiply the powers of same base  in denominator instead adding powers  of same base.

Step-by-step explanation:

We are given that Richard simplified an expression in threes steps

We have to find the incorrect step in simplification of Richard

Step 1: all the exponent are multiplied by 3

\frac{x^{-4}y^2}{yx^2\cdot x^2y^{-4}}^{3}=\frac{x^{-12}y^6}{y^3x^6\cdot x^6y^{-12}}

Step 2:The exponents in the denominator are multiplied

\frac{x^{-12}y^6}{y^3x^6\cdot x^6 y^{-12}}=\frac{x^{-12}y^6}{x^{12}y^{-9}}

Step 3:The exponents of the same base are subtracted during division

\frac{x^{-12}y^6}{x^{12}y^{-9}}=x^{-12-12}y^{6+9}

=x^{-24}y^{15}

Richard makes mistake in step 2 when we multiply  then power of same base should be added but Richard multiply the powers of same base  in denominator.
