Triangle QRS was dilated using the dilation rule DP,4.

Point P is the center of dilation. Triangle Q R S is dilated to create triangle Q prime R prime S prime. The length of P R is 3.

What is PR'?

6 units
9 units
12 units
15 units

Answers

Answer 1

Using the dilation rule, the length of P'R' is: C. 12 units.

What is Dilation?Dilation, as a type of transformation, is the enlargement or reduction of a shape to create a new image which is similar to the original image.If the scale factor is a whole number, it means it's an enlargement, if fraction, it means it is a reduction.

Given that the scale factor of dilation is 4, and PR is 3.

Therefore:

P'R' = 4(PR)

P'R' = 4(3)

P'R' = 12 units.

Therefore, using the dilation rule, the length of P'R' is: C. 12 units.

A triangle with sides 9, 12 and 15 is similar to a triangle whose longest side is 25. Find the perimeter of the larger triangle.​

Answers

Answer:

P = 60

Step-by-step explanation:

First, to find the scale factor, or how much bigger the other shape is, you can do so by comparing the two triangles' longest sides.

25       5

----  =  ----

15        3

So the larger triangle is 5/3 times bigger.

This means that all of its other sides with also be 5/3 times bigger.

So:

9 (5/3) = 45/3 = 15

12 (5/3) = 60/3 = 20

25 + 15 + 20 = 60

So the perimeter is 60.

You could have also found the perimeter of the smaller triangle, 9 + 12 + 15 = 36, then multiplied it by the scale factor, which would be:

36 (5/3) = 180/3 = 60

You would get the same thing.

Radius of the Inner circle:

5.4 is the diameter so find the radius, divide by 2 = 2.7

Next, take pi (3.14) and multiply with the radius (2.7), and use a power of 2.

3.14(2.7)^2 = 22.8906. Then round to the nearest tenth: 23.

Radius of Outer circle:

2.2 is the diameter so find the radius, divide by 2 = 1.1

Next, take pi (3.14) and multiply with the radius (1.1), and use a power of 2.

3.14(1.1)^2 = 3.7994. Then round to the nearest tenth: 4.

Radius of the Inner circle: 23

Radius of Outer circle: 4

Does 514, 684, 855 make a right triangle

Answers

Answer:

No, it does not.

Step-by-step explanation:

This does not make a right triangle because in order to have a right triangle you must have 2 of the same numbers.

For example:

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3

Answer:

Let's solve your equation step-by-step.

11x − 2x + 15 = 8 + 7 + 9x

Step 1:

Simplify both sides of the equation.

11x − 2x + 15 = 8 + 7 + 9x

11x + −2x + 15 = 8 + 7 + 9x

( 11x + −2x ) + ( 15 ) = ( 9x ) + ( 8 + 7 )

( Combine Like Terms )

9x + 15 = 9x + 15

9x + 15 = 9x + 15

Step 2:

Subtract 9x from both sides.

9x + 15 − 9x = 9x + 15 − 9x

15 = 15

Step 3:

Subtract 15 from both sides.

15 − 15 = 15 − 15

I need help! ABCD is a rectangle.

m<1 =
m<6 =
m<3 =

Answers

Answer:

m∠1 = 24°

m∠3 = 66°

m∠6 = 66°

Step-by-step explanation:

They are all near the corners of the rectangle

The corners always equal 90°

But as you can see, they are split down the middle by the X in the rectangle and we have only one angle to go off of; 24°

Since m∠1 is in the same triangle as that angle, and it looks exactly the same, the angle is exactly the same.

m∠3 and m∠6, if you look closely, are also the same. And as I said before, the corners always are 90°. Since 24° is taken from the neighboring triangle, the amount left is 66°, and remember, 24° + x° HAS to equal EXACTLY 90°. So

90 - 24 = 66

So both m∠3 and m∠6 = 66°

9 : 3

Step-by-step explanation:

To get from 21 to 3 we divided 21 by 7, therefore we have to do the same to the other side and so we get...

63 / 7 = 9

Therefore 63 : 21 = 9 : 3

9! ratios can be found by dividing. 21 divided by 3 is 7. therefore, divide 63 by 7 and get 9. 63:21=9:3
