Answer:

If the volume and the rafius of the cylinder is 271.4 cubic inches and 6 inches. Then the height of the cylinder will be 2.4 inches.

What is a cylinder?A cylinder is a closed solid that has two parallel circular bases connected by a curved surface.

If the volume of the cylinder is 271.4 cubic inches and the radius of the cylinder is 6 inches.

Then the height of the cylindr will be

We know the volume of the cylinder is given as

V = πr²h

Then we have

271.4 = π x 6² x h

271.4 = 36π x h

271.4 = 113.1 x h

h = 2.4

How to factor out tue coefficient of the variable

Lets say you have a question such as 7x+1=15.

First you have to start with the addition or subtraction because of PEMDAS. In order to get rid of the +1, you have to subtract 1 from it and do the same thing to the number on the other side of the equal sign.

7x+1-1=15-1

Which leaves you with

7x=14

What you want to do is get the variable by itself so, since the variable is basically multiplying itself by the coefficient, you want to divide the 7x by 7 to get rid of the coefficient. Make sure to do the same for both sides of the equation!

7x/7=14/7

x=2

Thats the answer.

Hopefully you can figure this out on your own problem.

A video game displays 96 frames in 4 seconds on Penelope's computer. What is the rate in frames per second?

Answer:

24 frames per second

Step-by-step explanation:

To find the rate in frames per second, take the frames and divide by the seconds

96 frames/ 4 seconds

24 frames per second

Which equation represents the relationship between x and y in the table below? X Y

-1 4

3 -12

5 -20

9 -36

A. y= x+4

B. y= x-4

C. y= 4x

D. y= -4x

Answer is D. y= -4x

x = -1, y = -4x = -4(-1) = 4

x = 3, y = -4x = -4(3) = -12

x = 5, y = -4x = -4(5) = -20

x = 9, y = -4x = -4(9) = -36

x = -1, y = -4x = -4(-1) = 4

x = 3, y = -4x = -4(3) = -12

x = 5, y = -4x = -4(5) = -20

x = 9, y = -4x = -4(9) = -36

Please help on a timed quiz The heights, in feet, of the trees for sale at two nurseries are shown below,

Yard Works: 7, 9, 7, 12,5

The Grow Station: 9, 11, 6, 12,7

Which statements are true regarding the measures of center and variability of these data sets? Select three choices.

A) The mean of the tree heights at Yard Works is less than the mean of the tree heights at The Grow Station.

B) The median of the tree heights at Yard Works is greater than the median of the tree heights at The Grow Station.

C) The range of the tree heights at Yard Works is greater than the range of the tree heights at The Grow Station.

D) The mean absolute deviation of the tree heights at Yard Works is greater than the mean absolute deviation of the tree heights at The Grow Station.

E) The mean absolute deviation of the tree heights at Yard Works is equal to the mean absolute deviation of the tree heights at The Grow Station

Answer: The range of the tree heights at yard work is greater than the range of the tree heights at the grow station

Step-by-step explanation:

yard works: 7,9,7,12,15

The grow station:9,11,6,12,7

mean of yard works = 7+9+7+12+15/5

=50/5=10

mean of grow station=

9+11+6+12+7 /5

=45/5 =9

The mean of tree heights at yard work is greater than that of grow station.

median(tree at yard work):7,7,9,12,15

median=9

median(tree at grow station)=6,7,9,11,12

median=9

The median of the tree height at yard work is equal to the median of that of tree station.

Range(yard work) = 15 - 7 =8

Range (tree station) =12-6=6

The range of the tree heights at yard work is greater to the tree heights at that of tree station

C.

If you blow air into a cup of water, does the water level change?

Since you are blowing warm air, the air molecules are moving fast so it makes the water expand. By the way that's what happens to a thermometer and I think this is a science question :)
