Answer:

$3.10

Step-by-step explanation:

Since there are three necklaces we multiply $3.80 x 3= $11.40

$20.70 - $11.40= 9.30

9.30/3= 3.10

Answer:

Step-by-step explanation:

Use  PEMDAS rule -----> Parenthesis , Exponent, Multiplication & Division and then Addition & subtraction.

23 + 18 ÷ (8 - 2) + 3  = 23 + 18 ÷ 6 + 3     {Now do division}

Answer:

4 inches wide

Step-by-step explanation:

We see that 984 ÷ 328 = 3, so the real Eiffel Tower is 3 times as tall as it is wide. So the scale model must also be 3 times as tall as it is wide. If the scale model is 12 inches tall, then it is 12 ÷ 3 = 4 inches wide.

Answer: It's congruent because translations, rotations, and reflections only move the shape's location and do not change the shape itself. A rotation changes the shape's position by rotating it around a specific point, but that shape is still the same. Reflections only mirror the shape, so while it will look inverted, it is still the same shape. Translations Only move a shape up or down along the y-axis or laft and right along the x-axis. Congruence essentially means that the shape has the same form and dimensions, not the exact location.

Answer:

Therefore, the selling price of the item is $35.1. Also, the clerks didn't put enough of the amount up too.

Step-by-step explanation:

Find out the selling price.

To prove

As given

A store manager instructs his employees to mark up all the items by 30%. An item that the store bought for $27.

30% is written in the decimal form.

= 0.30

30% of the $27 = 0.30 × 27

                         = $8.1

Selling price of the item = Original price of item + 30% of the $27

                                       = $27 + $8.1

                                           = $ 35.1

Answer:

The answer to your problem is, D. Yes, because 2 + 3 = 5.

Step-by-step explanation:

Refer to the converse of the pythagorean theorem. We need to have both sides equal to each other to have a right triangle.

So we need to have:

\(a^{2} + b^{2} = c^{2}\)

We would need to fill out the problem and replace A, B, and C. Which leads to either being B or D

The longest side is the hypotenuse and the value of c.

Thus the answer to our problem is, D. Yes, because 2 + 3 = 5

Answer:

The mode is 2

The range is 11

7 runs where scores 1 time

The median is 4

19 games

Step-by-step explanation:

The mode is 2 because that has the most dots meaning it was the most common

The highest was 11 and the lowest was 0

11-0=11

above the 7 had 1 dot meaning they only scored 7 runs once

the median is 4 because that is the middle

there where 19 dots in total meaning there were 19 games

Answer:

Step-by-step explanation:

66%

Answer:

Step-by-step explanation:

In this problem, both 7 and 14 can be divided by 1 and 7, meaning these are the factors. This tells us that 7 is the Greatest Common Factor, as 7 is greater than 1.

To factor the expression, we take 7 out of both numbers and put it outside the expression. To do this, we have to divide both numbers by 7. Doing this gives us \(7(\frac{7}{7} +\frac{14}{7} )\), which simplifies to \(7(1 + 2)\).

Answer: (-6, 9)

Step-by-step explanation:

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

We need to solve for k

y = x

21 = 7k  Divide both sides by 7 to solve for k

3 = k

y = xk

y = 5(3)

y = 15

Answer:

C

Step-by-step explanation:

The volume of a right rectangular prism is given by the formula V = lwh, where l, w, and h represent the length, width, and height of the prism, respectively. Since the prism is right and rectangular, the length and width are perpendicular to each other.

We are given that the height of the prism is 17.5 centimeters and the area of the base is 18 square centimeters. Since the base is rectangular, we can find the length and width by dividing the area by one of the dimensions and multiplying by the other. Let's say the length is x and the width is y, then:

xy = 18   (area of base)

y = 18/x  (solve for y)

Now, we can substitute the value of y in terms of x into the formula for the volume:

V = lwh = xyh = (18/x)(x)(17.5) = 315 cubic centimeters

Therefore, the volume of the right rectangular prism is 315 cubic centimeters.
