(also peter could totally be a girl and I am misgendered a person)

Answer:

The answer is 5.7%

Step-by-step explanation:

So Peter bought the makeup set that was $30.

and had to pay $1.71.

1.71 of 30.

So you would divide 1.71 with 30.

(1.71/30)

equaling .057

Then you would multiply by 100 because there is 100% total, and so multiplying that you would move the decimal two times to the right, getting 5.7

Answers

Answer:

It's A. 28 degrees

Step-by-step explanation:

First, you determine the angle measure directly below x. That is a straight line, so it measures 180 degrees. You can add 38 and 90 degrees, and then subtract from 180 to get the last angle measure. This gives you 52. The right 3 angles measure 90 degrees, because they are on the opposite side of a right angle marker. You can add 10 and 52 and then subtract from 90 to get the missing x value, 28.

centimeter.

The width of the model building is
centimeter.

The height of the model building is

The volume of the model building is
cubic centimeter.

Answers

6-7 that’s ur awnser girl

Based on the model, we find the dimensions of the cube. The length of the model building is 2/3 centimeter. The width of the model building is 1/3 centimeter. The height of the model building is 1/2 centimeter. The volume of the model building is 1/9 cubic centimeter.

What are dimensions of a cube?

A cube is 3- dimensional shape with 6 equal sides, 6 faces, and 6 vertices in geometry. Each face of a cube is a square. In 3 – dimension, the cube’s sides are; the length, width, and height. Sides of a cube are all equal i.e. Length = Width = Height = a.

The length = breadth = height (of one cube) = 1/6 cm

The length of the model consist of 4 cubes.

Length of model building = 4 * 1/6 cm = 2/3 cm

The width of the model consist of 2 cubes.

Width of model building = 2 * 1/6 cm = 1/3 cm

The height of the model consist of 3 cubes.

Height of model building = 3 * 1/6 cm = 1/2 cm

Volume of the model (cuboid) =

= Length * breadth * height

= [tex]\frac{2}{3} * \frac{1}{3}*\frac{1}{2} = \frac{1}{9}[/tex]
