The average of 9 scores is x. If the tenth score is 36 points more than x, by how many points will the tenth score raise the ave

Alecsey [184]

Answer:

3.6

Step-by-step explanation:

The average of 9 scores is x.

average = (sum of scores)/(number of scores)

x = (sum of scores)/9

sum of scores = 9x

The sum of the 9 scores is 9x.

The tenth score is 36 more than x, so it is x + 36.

The sum of the 10 scores is 9x + x + 36 = 10x + 36.

The average of the 10 scores is (10x + 36)/10 = x + 3.6

The difference of averages is

x + 3.6 - x = 3.6

An oil tank in the shape of a cylinder has a diameter of 40 feet and a height of 32 feet. Which expression can be used to find t

Volgvan

The volume of a cylinder is pi*r^2*h

The radius is half the diameter, so 40/2=20, and the radius is 20 ft.

Plugging in: pi*20^2*32=pi*400*32=12800pi=40212.38597

So the volume is about 40212.4 ft^3 and the expression we used is pi*20^2*32

Hope this helped!

Joshua has math and reading homework tonight. Joshua can solve each math problem in 2.5 minutes and he can read each page in 3 m

liraira [26]

Answer:

Joshua solved 7 math problems and tread 14 pages.

Step-by-step explanation:

Let x be the number of math problems Joshua solved. The number of pages Joshua read is twice the number of math problems he solved, then 2x is the number of pages Joshua read.

Joshua can solve each math problem in 2.5 minutes, then x math problems he solves in 2.5x minutes.

Joshua can read each page in 3 minutes, then 2x pages he reads in $3\cdot 2x=6x$ minutes.

It took him 59.5 minutes to complete all of his homework, so

$2.5x+6x=59.5$

Solve this equation:

$2.5x+6x=59.5\\ \\8.5x=59.5\\ \\85x=595\\ \\x=7\\ \\2x=14$

Joshua solved 7 math problems and tread 14 pages.
