Which type of transformation must have occurred in order to map triangle RST to its image, triangle R'S'T?​

Answer:

percentage change   ≈  140%

Step-by-step explanation:

There were 144 people in attendance at the school football game last Friday. This week there were 346 people in attendance at the school football game.What is the percent of change from last week to this week?Round your answer to the nearest whole number

To calculate the percentage change, we will follow the steps below:

First, we will find the difference(that is increase) between 144 and 346

Increase = New  number - Original number

             = 346 - 144

              = 202

Next is to divide the increase which is 202 by the original  number which is 144  and then multiply by 100

That is;

percentage change = increase ÷ original number × 100

                                   =202 / 144   ×  100

                                   ≈ 140    to the nearest  whole number

percentage change   ≈  140 %

Answer:

173,380

Step-by-step explanation:

just took the test and got it right

The expected cost of raising a child is $173,380.

Given,

C = 2.32 N + 34,180.

C represents the cost of raising a child.

N represents the income.

If the Murphy family has an annual income of $60,000.

We are to find the expected cost of raising a child using the given equation.

We have,

C = 2.32 N + 34,180________(A)

Now,

If the Murphy family has an annual income of $60,000.

N = $60,000___________(B)

Putting (B) in (A).

C = 2.32 x $60,000 + 34,180

C = 139,200 + 34,180

C = $173,380.

Thus the expected cost of raising a child is $173,380.

Answer:

C

Step-by-step explanation:

If  The probability of spinning a “1” is 0.25, then the probability of spinning 4 ones is:

0.25*0.25*0.25*0.25 = 0.25^4 ≈ 0.004

(the four events are independent)

The pointer landed on 1 each time, which probability is very low. So, we can conclude that the spinner is not fair.

Answer:

First option

Step-by-step explanation:

There is a mistake in the description of the first function.  

On a coordinate plane, a straight line with a positive slope crosses the x-axis at (-6, 0) and the y-axis at (0, 3). Solid circles appear on the line at (-4, 1), (0, 3).

Given two points of a function, (x1, y1) and (x2, y2), its rate of change between them is:

Rate of change: (y2 - y1)/(x2 - x1)

Points of the 1st graph: (-4, 1), (0, 3).

Rate of change: (3- 1)/(0 - (-4)) = 1/2

Points of the 2nd graph: (-4, 1), (0, -3).

Rate of change: (-3 - 1)/(0 - (-4)) = -1

Points of the 3rd graph: (-4, 0), (0, 4).

Rate of change: (4 - 0)/(0 - (-4)) = 1

Points of the 4th graph: (-4, 0.25), (0, 4).

Rate of change: (4 - 0.25)/(0 - (-4))   = 0.9375

Answer:

Step-by-step explanation:

answer on edge

Step-by-step explanation:

Total fruits = 7+ 4 = 11

Probability of apples = 7/ 11

The probability of the apples should be [tex]7\div 11[/tex]

Since A basket contains seven apples and four peaches. You randomly select a piece of fruit and then return it to the basket.

So here the total fruits should be

= 7 + 4

= 11

Now the probability of the apple should be [tex]7\div 11[/tex]

hence, we can conclude that The probability of the apples should be [tex]7\div 11[/tex]

Answer:

-1.5

Step-by-step explanation:

4x - 36 = 36 + 52x

We can make this into another equation.

72 + 52x = 4x

4x - 52x = -48x

-48x = 72

48x = -72

x = -72/48 = -1.5

Pls do mark me as brainliest.Thanks! ;)

Answer:

x = - [tex]\frac{3}{2}[/tex] = - 1.5

Step-by-step explanation:

Given

4(x - 9) = 4(9 + 13x) ← distribute parenthesis on both sides

4x - 36 = 36 + 52x ( subtract 52x from both sides )

- 4x - 36 = 36 ( add 36 to both sides )

- 4x = 72 ( divide both sides by - 4 )

x = [tex]\frac{72}{-4}[/tex] = - [tex]\frac{3}{2}[/tex] = - 1.5

Answer:

x=45

Step-by-step explanation:

Because angles TRS and TRV are a linear pair, their two angle measures must add up to 180 degrees. Therefore:

Answer:

13.6

Step-by-step explanation:

The measure of the segment AQ is related to the measure of the segment A'Q by the dilation factor as follows:

dilation factor = A'Q/AQ

AQ = A'Q/dilation factor

Replacing with data:

AQ = 2.4/0.15 = 16

Then, the distance between points A and A' is

x = 16 - 2.4 = 13.6

The  distance between points A and A' is 13.6 units

Dilation is a way of changing the position of an image on an xy-plane.

The measure of the segment AQ is related to the measure of the segment A'Q by the dilation factor. Hence'

scale factor = A'Q'/AQ

Given the following

A'Q' = 2.4

Scale factor = 0.15

Substitute

AQ = 2.4/0.15

AQ = 16

x = 16 - 2.4

x = 13.6

Hence the  distance between points A and A' is 13.6 units
