1) Find the area of the pizza assuming a uniform regular circular shape. 

Area = PI * 0.25 * (D)^2

A1 = 3.14 * 0.25 * (12)^2 = 113.04 in^2

A2 = 3.14 * 0.25 * (8)^2 = 50.24 in^2

Pizza difference = 113.04 - 50.24 = 62.8 in^2

More pizza = 62.8/50.24 x 100  - 100 = 25 %

Which rule is an example of rigid transformation?
GalinKa [24]

We know that

Rigid transformation:

A rigid transformation (also called an isometry) is a transformation of the plane that preserves length.

Reflections, translations, rotations, and combinations of these three transformations are "rigid transformations"

so, it's length must be preserved

now, we will check each option

option-A:

we have (x,3y)

y-value changes but x-value will remain same

It changes length

so, this is not rigid transformation

option-B:

we have (3x,y)

x-value changes but y-value will remain same

It changes length

so, this is not rigid transformation

option-C:

(2x, y+2)

It changes length of x-value

but it is only shifting y-value

so, it changes length

so, this is not rigid transformation

option-D:

Both shifts values

but it's length will always be same

so, this is rigid transformation..............Answer

Please, someone, help with this question. This is my last question.
Leya [2.2K]

Answer:

4.43 inches

Step-by-step explanation:

The volume of the hot tub is

V = l*w*h

We are given the volume in gallons which we need to convert to cubic inches

1 gallon = 231  in^3

350 gallons *231 in ^3/1 gallon = 80850 in ^3

Substituting in what we know, we can find the height of the tub

80850 = 76*60 *h

17.76026316 is the height of the tub

If the tub is 1/4 full

We take 1/4 of the height

1/4 * 17.76 = 4.432565789

The approximate height of the water is 4.43 inches
