Answer:

900

Step-by-step explanation:

perimeter: P = 2w + 2h

P = 2(20) + 2(25)

P = 40 + 50

P = 90

Multiply perimeter by 10:

90 × 10 = 900

How do you find a volume of a cube and Rectangular prism and a cylinder? PLEASE HELP ASAP ASAP PLEASSEEEEEEE I BEG YOU
Nat2105 [25]

Of course!

Cube: side length * side length * side length

So if it's a 6x6x6 cube, it's 6*6*6 = 216

Rectangular Prism: side length * side height * base width

So if it's a 6x7x8 prism, it's 6*7*8 = 336

Cylinder: π * (radius squared) * height

So if the base's radius is 6 and the height is 7, it's π*6^2*7 = 252π

Which function has the greatest constant of variation? A x 8 9 10 11 y 20 22.5 25 27.5 B x 1 2 3 4 y 3.2 6.4 9.6 12.8
Lina20 [59]

Answer : B x 1 2 3 4 y 3.2 6.4 9.6 12.8

WE analyze the first option A

x -- y -- Difference

8 -- 20

9 -- 22.5 -- 2.5

10 -- 25 -- 2.5

11 -- 27.5 -- 2.5

From the first function we can see there is a constant difference of 2.5.

We analyze the second option B

x -- y -- Difference

1 -- 3.2

2 -- 6.4 -- 3.2

3 -- 9.6 -- 3.2

48 -- 12.8 -- 3.2

From the second function we can see there is a constant difference of 3.2

3.2 is the greatest

So second function B has the greatest constant of variation.

seropon [69]
So the equation you’ll use for both is
WP = mg • h
It’s delta height generally.

1.) .9 m = h

2.) 216 = WP

I would’ve sent a screenshot, but the app wouldn’t let me.
