Draw the image of \triangle ABC△ABCtriangle, A, B, C under a dilation whose center is PPP and scale factor is 222.

Answers

Answer:

sorry if im wrong i think wrong numbers. plz check

Step-by-step explanation:

The center of dilation of the question is (-4,-3) .

let say that

x0=-4

y0=-3

Label the image A'B'C'

The new coordinate would be

A(-4,-1)

x=4

y=-1

x'=x0+ 2(x - x0)

x'= -4+ 2(-4 +4)

x'=-4

y'=y0+ 2(y - y0)

y'= -3+ 2(-1 +3)

y'=-3 +4= 1

______________________________

B(-4,-3)

x=-4

y=-3

x'=x0+ 2(x - x0)

x'= -4+ 2(-4 +4)

x'=-4

y'=y0+ 2(y - y0)

y'= -3+ 2(-3 +3)

y'=-3

Write an expression to represent the perimeter of the figure below.

Answers

Step-by-step explanation:

A perimeter is when you add up all of the sides

Here would be our equation

[tex]2(x+4)+2(2x-8)[/tex]

Answer: The expression for this would be 2(x+4) + 2(2x-8)

Step-by-step explanation:

This is because when we calculate perimeter, we add up all the sides. So, instead of doing (x+4)+(x+4), we can just do 2(x+4) and add up all sides. So, here’s the answer in simplest form!

6x - 8. Hope this helped!

Answers

a) 20.9

    The mean is calculated by adding up the scores and dividing the total by the number of scores, it is also called the average.

    First, we can count and see there are 11 players (makes sense for a football team). Adding up the ages gives us 19 + 19 + 20 + 20 + 20 + 21 + 22 + 22 + 22 + 22 + 23 = 230. Divide by 11 and we get a mean of of about 20.9!

b) 30

To figure this out, we will set up an equation that looks like this:

[tex]\frac{19 + 19 + 20 + 20 + 20 + 21 + 22 + 22 + 22 + 22 + 23+x}{12} =22[/tex]

And now we will solve:

[multiply both sides by 12] 230 + x = 264

[subtract 130 from both sides] x = 30

So the age of the new player should be 30!

Have a nice day!

The school band has a goal of raising $800 for some new uniforms. If they have raised $512 so far, what percent of their goal have they raised?

Answers

Answer: 64%

Step-by-step explanation:

The band needs $800 for new uniforms and of that, they only raised $512.

Set up a proportion [tex]\frac{part}{total} = \frac{percentage}{100}[/tex]and plug everything you know in.

[tex]\frac{512}{800}[/tex] = [tex]\frac{x}{100}[/tex]

Solve for x by cross multiplying and dividing.

512 × 100 = 51200

51200 ÷ 800 = 64

x = 64

The school band has raised 64% of their goal already.

Answer:

The Answer would be 64%

The total change in the outdoor temperature over 6 hours was -21°F
What was the mean change in temperature per hour?

₋₋₋₋₋₋₋₋ °F per hour

Answers

Answer:

-3.5

Step-by-step explanation:

As there was a total change of -21, that would be the first part of your equation:

-21

As 6 hours had passed and you are trying to find the mean, your equation would now be:

-21 ÷ 6 = ?

Now you can solve the equation, and the answer is -3.5°F per hour.

The mean change in temperature per hour is -3.5 °F.

what is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

The total change in the outdoor temperature over 6 hours was -21°F

So, in one hour the mean change in temperature

= -21/6

= -3.5 °F

Hence, the mean change in temperature per hour is -3.5 °F.

−5.6x=−4

What is the solution to the equation?

Enter your answer as a simplified fraction in the box.

Answers

Answer: 0.714285

Step-by-step explanation:

The solution of the equation (-5.6 = -4) is (x = 5/7) and this can be determined by using the arithmetic operations.

Given :

-5.6x = -4

The following steps can be used in order to determine the solution to the equation (-5.6x = -4):

Step 1 - The arithmetic operations can be used in order to determine the solution to the given equation.

Step 2 - Write the given equation.

-5.6x = -4

Step 3 - Add 4 on both sides in the above equation.

-5.6x + 4 = -4 + 4

-5.6x + 4 = 0

Step 4 - Add 5.6x on both sides in the above expression.

-5.6x + 4 + 5.6x = 5.6x

4 = 5.6x

Step 5 - Divide 4 by 5.6 in the above expression.

[tex]x = \dfrac{4}{5.6}[/tex]

Step 6 - Simplify the above expression.

[tex]x = \dfrac{5}{7}[/tex]
