11. 6:18 = 1:3
12. 12:48 = 1:4
13. 17:34 = 1:2
14. 8:64 = 1:8

15. 44:4 = 11:1
16. 121:11 = 11:1
17. 12:2 = 6:1
18. 4:2 = 2:1

19. 3:4 and 2:3 = 9:12 and 8:12
20. 1:6 and 3:14 = 7:42 and 9:42
21. 2:7 and 3:5 = 10:35 and 21:35

A circle has an area of 30 in^2. What is the area of a 60 sector of this circle?

yuradex [85]

We use the ratio x:360 to find portions of the circle (again, through the ratio)

so we use 60/360 = x/30 in^2

1/6 = x/ 30

x = 5.

The answer is 5 in^2

what is the sum of two numbers is "-7." Two times the first number equals 4 the second number. Find the two numbers.

skelet666 [1.2K]

Answer:

$\sf \text{The numbers are $\dfrac{-14}{3} $ and $\dfrac{-7}{3}$}$

Step-by-step explanation:

Let the numbers be x , y

Sum of two numers = -7

x + y = -7------------(I)

Two times the first number equals 4 the second number.

2x = 4y ----------(II)

Divide both sides by 2

$\sf \dfrac{2x}{2}=\dfrac{4y}{2}$

x = 2y

Subtitute x = 2y in equation (I)

2y + y = -7

3y = -7

y = -7/3

Plugin y = -7/3 in equation (II)

$\sf 2x = 4*\dfrac{-7}{3}\\\\2x = \dfrac{-28}{3}\\\\x =\dfrac{-28}{3*2}\\\\x = \dfrac{-14}{3}$
