Answer:

The answer is 15 Shirts

Step-by-step explanation:

We want to know what x is going to equal that makes the equation the same.

First, I make the euations equal to each other by substituting the y -->

7x + 50 = 10x + 5

Then, I combine my similar terms --> 45 = 3x

After that, I divide by 3 to get x on its own --> [tex]\frac{45}{3} =\frac{3x}{3}[/tex] --> 15 = x

This means that after 15 Shirts are sold, the costs for both companies are the same.

You will get. 15 shirts

Find the mean, median, and mode of the data set. Round to the nearest tenth.

5, 7, 2, 6, 7, 10, 12, 7, 9, 13, 5

Answers

Answer:

The mean is 7.5.

The median is 7.

The mode is 7.

Step-by-step explanation:

To find the mean, add up all the numbers in the data set and then divide the sum by the total number of values.

5 + 7 + 2 + 6 + 7 + 10 + 12 + 7 + 9 + 13 + 5 = 83

83 divided 11 equals 7.5.

To find the median, arrange all the numbers in the data set from smallest to largest and then find the number that is in the middle of the set.

To find the mode, put the numbers in order from least to greatest and count how many times each number occurs. The number that occurs the most is the mode.

the mean is 7.5 the median is 7 and more is 7

the answe is A 112 square units

Answer:

Step-by-step explanation:

First find the area of the entire figure.

L= 36

W = 20

Area = 36 * 20 = 720

Find the area of the left right triangle.

Height = 20

Base = 1/2 * 36 = 18

Just as an aside, let me be a little grumpy for a moment. You should never have to guess what a dimension is on a diagram. It's sloppy. However for this problem you have no choice. But you could think to complain to your teacher.

Area = 1/2 * base * height

Area = 1/2 * 18 * 20 = 180

Find the area of the bottom right triangle.

The height is 1/2 20 = 10

The base is 36

Area of the lower triangle = 1/2 * 36 * 10 = 180

Area of the shaded figure = 720 - 180 - 180 = 360

Step 2: Find 4 to the power of 3.

4 x 4 x 4 = 64

Now find 2 to the power of 3

2 x 2 x 2 = 8

Step 3: Subtract the two values as mentioned in the equation:

64 - 8 = 56

Step 4: Now divide 56 by 4 as mentioned in the equation.

56 ÷ 4 = 14

How many lines of symmetry are in a regular polygon?

twice as many as the number of sides
half as many as the number of sides
the same number as the number of sides

Answers

Answer:

the same number as the number of sides

lines of symmetry are in a regular polygon is the same number as the number of sides.

the correct option is (D)

What is Line of symmetry?

A line of symmetry is a line that cuts a shape exactly in half. This means that if you were to fold the shape along the line, both halves would match exactly.

The number of lines of symmetry in a regular polygon is equal to the number of sides.

For example,

It has four lines of symmetry and four sides. A regular pentagon has 5 sides and 5 lines of symmetry.

Hence, lines of symmetry in a regular polygon is equal to the number of sides.
