In converting 9 inches to yards, what unit (omit the number) would you place
Anna35 [415]

Answer:

<u>9 inches are 1/4 or 0.25 yards and we used inches in the numerator and yards in the denominator for our ratio.</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

1 yard = 36 inches

2. In converting 9 inches to yards, what unit (omit the number) would you place  in the numerator of your ratio?

This is the ratio for calculating the answer:

36/1 = 9/x

36x = 9 *1

36x = 9

x = 9/36

x = 1/4 or 0.25 yards

<u>9 inches are 1/4 or 0.25 yards and we used inches in the numerator and yards in the denominator for our ratio.</u>

The larger of two numbers is 4 more than 2 times the smaller number. If the sum of the two numbers is 28, what is the larger num
Musya8 [376]

Answer:

The larger number is 20.

Step-by-step explanation:

Let x and y be the two numbers.

y = 2x + 4

x + y = 28

So x + 2x + 4 = 28

3x = 24

x = 8

y = 20

Wires are attached to a pole to make it more secure. The diagram shows one of those wires having a length of 220 feet. The angle
LuckyWell [14K]
The wire, the pole and the segment joining the leg of the pole to the wire in the ground form a right triangle whose hypotenuse is the wire, and the side opposite to the angle 36° is the pole.

By right triangle trigonometry, sin36°=(opposite side)/(hypotenuse.)

Substituting, we have 0.588=(opposite side)/220, thus the length of the opposite side, which represents the length of the pole, is 

                                       0.588*220 ft=129.3 ft
