I need help with this.

Answer:

x>30

Step-by-step explanation:

x/-3<-10

x<-10*-3

x<30

x>30

Answer:

x > 30

Step-by-step explanation:

Multiply both sides by -3:  This results in x > 30.  Note that the direction of the inequality sign has been reversed, as is required when we multiply or divide an inequality by a negative number.

Answer:

  (a)  A'(-2, 1), B'(-4, -3), C'(-7, 0)

Step-by-step explanation:

If X is the center of rotation, the coordinates of point P are transformed like this:

  P' = -(P -X) +X

  P' = 2X -P

  (x, y) ⇒ (2(-5) -x, 2(3) -y)

  (x, y) ⇒ (-10-x, 6-y)

__

Your points are transformed to ...

  A(-8, 5) ⇒ (-10-(-8), 6-5) = A'(-2, 1)

  B(-6, 9) ⇒ (-10-(-6), 6-9) = B'(-4, -3)

  C(-3, 6) ⇒ (-10-(-3), 6-6) = C'(-7, 0)

These coordinates match the first choice.

Answer:  4/5 (first choice)

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

Work Shown:

sin(angle) = opposite/hypotenuse

sin(A) = BC/AC

sin(A) = 24/30

sin(A) = (6*4)/(6*5)

sin(A) = 4/5

Answer:

See below.

Step-by-step explanation:

The ratio of cats to dogs would be 2/5. This is the simplest ratio, but I assume you are looking for other ratios that are equal to 2/5

Since you did not provide choices to pick from, I can't really answer your question. But, some ratios that are equal to 2/5 are 4/10, 6/15, 8/20, and 10/25.

Answer:

91

Step-by-step explanation:

the formula for a triangle is base x height divided by 2

so the base is 13 and the height is 14

multiply 13 and 14 then divide by 2

13 x 14 = 182/2= 91

Answer:

1.) Scale factor from the actual flower garden to the scale drawing = 20 : 1

2.) Dimensions of the flower garden in the new scale drawing = 7.5 inches × 11.25 inches

3.) Scale factor from the actual flower garden to the new scale drawing = 8:1

Step-by-step explanation:

Given - Penny’s backyard contains a flower garden. The dimensions of the

             actual garden are 5 feet by 7½ feet. A scale drawing of the flower

             garden is 3 inches by 4.5 inches.

To find - 1. What is the scale factor from the actual flower garden to the

                  scale drawing?

              2. If the drawing is enlarged by a scale factor of 5/2, what would    

                  be the dimensions of the flower garden in the new scale

                  drawing?

              3. What is the scale factor from the actual flower garden to the

                   new scale drawing?

Proof -

As we know that,

1 feet = 12 inches

⇒5 feet  = 5×12 = 60 inches

  7½ (= [tex]\frac{15}{2}[/tex]) feet = [tex]\frac{15}{2}[/tex]×12 = 90 inches

∴ we get

The dimensions of the actual garden is 60 inches by 90 inches.

1.)

As,

[tex]\frac{60}{3} = \frac{20}{1} = 20 : 1[/tex]

[tex]\frac{90}{4.5} = \frac{900}{45} =\frac{20}{1} = 20 : 1[/tex]

So,

Scale factor from the actual flower garden to the scale drawing = 20 : 1

2.)

As given,  If the drawing is enlarged by a scale factor of 5/2

⇒Dimensions of flower garden = 3×[tex]\frac{5}{2}[/tex] inches by [tex]4.5 (\frac{5}{2})[/tex] inches

                                                    = 7.5 inches by 11.25 inches

∴ we get

Dimensions of the flower garden in the new scale drawing = 7.5 inches × 11.25 inches

3.)

Scale factor from the actual flower garden to the new scale drawing = [tex]\frac{60}{7.5}[/tex] = [tex]\frac{600}{75} = \frac{8}{1} = 8 : 1[/tex]

Answer:

46.69

Step-by-step explanation:

Multiply 58 by .805

Answer:

measure of both angles is 52°

x = 16

Step-by-step explanation:

5x - 28 = 3x + 4

2x - 28 = 4

2x = 32

x = 16

Plug in 16 for 'x': 3(16) + 4 = 48 + 4 = 52°

Answer:

Both are 56°

Step-by-step explanation:

5x-28=3x+4

x=16

5(16)-28= 56°

Answer: b

Step-by-step explanation:

Answer:

x = 12

Step-by-step explanation:

x = length of side of square A

'x-3' represents length of side of square B

Perimeter of square A = 4x

Perimeter of square A = 4x - 12

we can set up the following proportion based on ratio of 4:3

4x / 4 = 4x - 12 / 3

cross-multiply:

4(3x) = 4(4x-12)

12x = 16x - 48

-4x = -48

x = 12
