What is the perimeter of the triangle?

Answers

We can count the bottom units to get 10 units. Now to get the sides of it.

Let’s split this triangle in the middle to get two right triangles.

The height of the triangle is 12 units and one of the legs is 5 ( from 10/2 )

Let’s find the hypotenuse

(5) ^2 + (12) ^2 = c^2

C = 13

So this mean each side is 13 units

13 + 13 + 10 = 36 units

Perimeter = 36 units

Step-by-step explanation:

Answer:

x = -4

Step-by-step explanation:

-9 (1/2x - 3) = 45

Divide both sides by -9

1/2x - 3 = -5

Add 3 to both sides

1/2x = -2

multiply both sides by 2

x = -4

What is the value of x?

Answers

Answer:

28!

Step-by-step explanation:

soooooo its a 90 degree angle

2x+1+33=90

2x+34=90

    -34  

2x=56

x=28

Answer:

x = 28°

Step-by-step explanation:

As you see that the angle is an right angle where right angles = 90°

So,

(2x + 1) + 33 = 90°

Subtract 33 on both sides:

2x + 1 = 57

Subtract 1 on both sides:

2x = 56

Divide 2 on both sides:

x = 28°

What is the median of these numbers :
90, 95, 92, 93, 91, 97

Answers

Answer:92.5

Step-by-step explanation:

The middle numbers are 92 and 93 and then you add 92+93=185 and 185/2=92.5

The median is 92.5

Work :

1) Place the numbers in order
90, 91, 92, 93, 95, 97

2) There are two medians (92 & 93)

3) Add both numbers then divide by 2, because it’s two numbers and you need 1 median

92+93 = 185/2 = 92.5

Can someone give me a small lesson on nets and surface areas??

Thank you if you can. I really don’t understand.

Answers

Hi!

Here is the definition of a net from www.icoachmath.com:

“Net is a two-dimensional pattern of a three-dimensional figure that can be folded to form the figure. In other words, net is a flattened three-dimensional figure which can be turned into the solid by folding it.”

In the photo is an example of a net of a rectangular prism.

Surface area is the measure of the total area of the surface of a 3D object. For example, if I have a cube, the surface area would be the area of the outside of the cube.

Hope this helped,

3(1.5x + 9)= -9

Answers

Answer:

x = -8

Step-by-step explanation:

3(1.5x + 9) = -9

Divide both sides by 3

1.5x + 9 = -3

Subtract 9 from both sides

1.5x = -12

Divide both sides by 1.5

x = -8

Answer:

x = -8

Step-by-step explanation:

3(1.5x + 9)= -9

=> 4.5x + 27 = -9

=> 4.5x = -9-27

=> 4.5x = -36

[tex] = > \frac{45x}{10} = - 36[/tex]

Step-by-step explanation:

25.5/5=5.1

5.1*2=10.2

The width is 10.2 inches

25.5*2+10.2*2=71.4

The perimeter is 71.4 inches

What is the scale factor of the dilation?

Is the dilation an enlargement or a reduction?

Answers

Answers:

Scale Factor = 3/4

This is a reduction

======================================================

Explanation:

Let's focus on the point R(4,4). That's the preimage point for the image of R ' (3,3).

Let k be the scale factor. We multiply this value of k by the x,y coordinates of point R to jump to R '

we have x = 4 jump to 4k which is the x coordinate of point R'

So we set 4k equal to 3 and solve for k to get k = 3/4. The scale factor is 3/4 or 0.75

We have a reduction since the image triangle T'R'S' is smaller compared to the preimage triangle TRS. We can see that we have a reduction by looking at the scale factor. If 0 < k < 1, then we have a reduction. If k > 1, then we have an enlargement instead. So we go with the first option since 0 < 3/4 < 1 or you could say 0 < 0.75 < 1.

Answer:

A reduction (think shrinking) is a dilation that creates a smaller image, and an enlargement is a dilation that creates a larger image

I haven't done these in 2 years and I'm not sure if I remember things correctly but here's what I would put down.

5) No, it is not because the sizes of each section are not even.

6) Yes, this is fair since there are a even chance of getting each number.

7) 3 out of 25 or 3/25

8) The bag with 250 colored tiles would give him a less chance of picking a blue tile. In the first bag, there is a 40% chance that Greg would pick a blue tile while the second bag, he would have a 30% chance of picking a blue tile. To get these percentages, I divided the the amount of blue tiles in the bag by the total amount of tiles.

Explantion for question 8: 10 blue tiles in a bag of 25 so you would do 10/25 which is .4 and as a percentage it would be 40%. For the second question, 75 blue tiles out of 250 total so 75/250 and that would be .3 and as a percentage, it would be 30%. The "/" is a fraction bar and is sometimes used as a division symbol as well, just in case you don't know:)

Record your measurements on a piece of paper. Using a tape measure or ruler, measure the length (in inches) of a persons left foot and then measure the length (in inches) of that same persons forearm (between their wrist and elbow). Refer to the diagrams below. You will have two measurements for each person.(An easy way to measure the length of a foot is to have your subject stand on a piece of paper. Then, trace their foot and measure the outline once they move off the paper.)To measure the forearm, measure inside the arm, between the wrist and the elbow.Part 2Organize your data and find the rate of change.Create a table of the measurements for your data. Label the forearm measurements as your input and the foot measurements as your output. Select two sets of points and find the rate of change for your data. Describe your results. If you had to express this relation as a verbal statement, how would you describe it?Part 3Compare rates of change.The equation below can be used to find the length of a foot or forearm when you know one or the other.(length of the foot) = 0.860 (length of the forearm) + 3.302 If you let y = length of the foot and x = length of the forearm, this equation can be simplified to y = 0.860x + 3.302.Using this equation, how long would the foot of a person be if his forearm was 17 inches long? What is the rate of change of the equation from Part A? Compare the equation from Part A to your data. Are they the same? Which has a greater rate of change? Why do you think the values are different?Is the relation in your data a function? Why or why not? Could the equation in Part A represent a function? Why or why not?
