pls, help for the first person to answer I will give them a brainlist.

Answers

Answer 1

Answer:

x= 3/17

Step-by-step explanation:

4x(2x+6) =8x^2(23-5)

8x^2 +24x = 144 x^2

24x = 136 x^2

24= 136 x

x=24/136

x=3/17

A first number is four more than seven time a second. The sum of the number is 92. Find the number.​

Answers

Answer:

11

81

Step-by-step explanation:

x = 7y + 4

x + y = 92

Solve for x in the second equation

x = 92 - y

92 - y = x

Equate the 2 xs

92 - y = 7y + 4         Add y to both sides

92 = 7y+y + 4          Combine

92 = 8y +  4             Subtract 4 from both sides

88 = 8y                    Divide by 8

88/8 = y

y = 11

First you add 3x+x because they are like terms.

3x+x-7=10  

Your New Simplified Equation:

4x-7=10  

Now, you have to take out the -7 by adding a positive 7. Also you                          have to add +7 on the other side so add 7 to 10.

Your New Simplified Equation:

4x=17      Now, you divide both sides by 4.

The scale of a square map indicates that each inch on the map
corresponds to 5 miles. Write an expression that describes the area of
land shown on the map. If the map is 8 inches on one side, what is the
area of land shown on the map?

Answers

Answer:

Area of land: 800 miles.

Step-by-step explanation:

Since the map is a square, you can assume that all 4 sides will equal 8 inches. (Giving you a perimeter of 32, and an area of 64.) Since each inch corresponds to 5 miles, you multiply 8 by 5 which equals 40.

When the outlier(s) are removed, how does the mean change? dot plot with 1 dot over 15, 1 dot over 23, 1 dot over 24, 1 dot over 25, 1 dot over 26, 1 dot over 27, and 1 dot over 35
The mean doesn't change.
The mean increases by 2.
The mean decreases by 2.
There are no outliers.

Answers

Answer:

So the answer is A-The mean doesn't change

Step-by-step explanation:

With the outliers the mean is 25, how?

well if we put down the numbers 15,23,24,25,26,27,35 and add them together  15+23+24+25+26+27+35 we get 175 now we have to divide by how many numbers are there 175/7=25. That is the mean WITH the outliers.

Now, WITHOUT the outliers. The outliers are 15 and 35. We know this because, there is a huge gap between 15 and 23, and 27 and 35. We basically do the same thing but without the outliers. 23+24+25+26+27=125 we divide by how many numbers are there 125/5 then we get 25.

Hey love! <3

Answer:

The correct answer is A. The mean doesn't change

Step-by-step explanation:

Since this is a dot plot, first we have to count up the total x-axis amount from the dot plots, then divide it by the numeral amounts (y-axis), then repeat this after removing the outlier from the dot plot.

Thus, the mean remaining the same.

The side length of the base of a square pyramid is 30 centimeters. The height of the pyramid is 45 centimeters.
What is the volume of the pyramid in cubic centimeters?

Answers

Answer:

volume = 13500 [tex]cm^{3}[/tex]

Step-by-step explanation:

For a given pyramid, its volume can be determined by:

volume of pyramid = [tex]\frac{lwh}{3}[/tex]

Where: l is the base length, w is the base width and h id the height of the pyramid.

For the given question, l 30 cm, w = 30 cm and h = 45 cm.

So that,

volume = [tex]\frac{30*30*45}{3}[/tex]

            = [tex]\frac{40500}{3}[/tex]

            = 13500

volume = 13500 [tex]cm^{3}[/tex]

The volume of the pyramid is 13500 [tex]cm^{3}[/tex].

The volume of the square-based pyramid is [tex]13500cm^3[/tex]

The volume of a pyramid is given by

[tex]V=\dfrac{Ah}{3}[/tex]

where

[tex]A=\text{area of the square base}\\h=\text{perpendicular height}[/tex]

The area of the square base, [tex]A[/tex], is calculated as follows

[tex]A=side^2\\=(30cm)^2\\=900cm^2[/tex]

substitute the value of [tex]A[/tex], and [tex]h[/tex] ([tex]45cm[/tex]) into the volume formula to calculate the pyramid's volume

[tex]V=\dfrac{Ah}{3}\\\\=\dfrac{900\times 45}{3}\\\\=13500cm^3[/tex]

Therefore, the volume of the pyramid is [tex]13500cm^3[/tex]

Estimate amount of cereal in one bag is 5.867 ounces.

What are mathematical operations?

Calculate the answer using a math operator is referred to as a mathematical operation.

Basic mathematical operations are addition, multiplication, subtraction and division.

Total quantity of cereal that Lazare has = 52.8 ounces.

And number of bags into which cereal equally divides = 9

To find the amount of cereal in each bag,

Use mathematical operations,

Since, total bags are 9 and amount of cereal is 52.8 ounces.

So, in one bag amount of cereal = 52.8 / 9 = 5.8666 = 5.867

So if the ratio of red to blue is 8:3 and there are 15 blue cars then there are 40 red cars.
If the ratio of red to white is 2:10 then then there are 200 white cars.

Explanation:
15 divided by 3 is 5. So you multiply 8 by 5 to get 40. 40:15 reduces to 8:3.

With 40 red cars the ratio of 2:10 would be made into 40:200.
