B -2

C 2

D 12

Answers

Answer 1
D. 12 is your answer

To get rid of the -5/6, you Have to multiply both sides of the equation by it’s inverse, which is -6/5.

-10 x -6/5 = 60/5 = 12
Answer 2

Answer:

K = 12, so the correct answer is D.

Step-by-step explanation:

- [tex]\frac{5}{6}[/tex]K = -10

-5K = -60 (Multiply 6 to both sides)

K = 12 (Divide both sides by 5)

One circle has a diameter of 6 inches. A second, larger circle has a diameter that is four times the diameter of the first circle. What is the ratio of the area of the smaller circle to the larger circle?

A 2:3
B 1:6.4
C 1:16
D 1:64

Answers

Answer:

Step-by-step explanation:

d₁ = 6 inches

r₁ = 3 inches

area = πr₁² = 9π in²

d₂ = 24 inches

r₂ = 12 inches

area = πr₂² = 144π in²

ratio of areas = (9π)/(144π) = 9/144 = 1/16

Answer:

1. 258 square meters

2. 180 square meters

3. 286 square feet

Step-by-step explanation:

1. Find the surface area of each side:

9 * 5 + 5 * 6 + 9 * 5 + 6 * 5 + 9 * 6 + 9 * 6

45 + 30 + 45 + 30 + 54 + 54

75 + 75 + 108

150 + 108

258

2. Base: 5 * 5 = 25

Top: 5 * 5 = 25

Sides: each 5 * 6.5 = 32.5

Altogether: 32.5 * 4 = 130

130 + 25 + 25 = 180

3. Base and top: both 8 * 10 = 80, together 80 * 2 = 160

Front and back sides: both 8 * 3.5 = 28, together 28 * 2 = 56

Left and right sides: both 10 * 3.5 = 35, together 35 * 2 = 70

Altogether: 160 + 56 + 70 = 286 sq feet

100 points!

Answers

Answer: 6 feet


Explanation: Since the triangles are similar, we can use the proportion 9/4=(12x+2)/(5x+1).

Cross multiplying 9*(5x+1) and 4*(12x+2) gives us 45x+9=48x+8.

Solving for x gives us 1/3.

You can check your work by plugging in x for the two equations, which gives us 6 (RS) and 8/3 (R’S’)

The scale factor is 4/9 (k) from 9k=4

6*4/9=8/3 and (8/3)/(4/9)=6

Answer:

RS = 6 feet

Step-by-step explanation:

Use ratios of corresponding sides:

TS/T'S' = RS/R'S'

Substitute and solve for x:

9/4 = (12x + 2)/(5x + 1)9(5x + 1) = 4(12x + 2)45x + 9 = 48x + 848x - 45x = 9 - 83x = 1x = 1/3

Find the length of RS:

RS = 12x + 2 = 12(1/3) + 2 = 4 + 2 = 6 feet
