Two angles with measures (6x + 60) and (90) are supplementary. What is the value of x?

Answers

Supplementary angles add up to 180, so
6x+60+90 = 180 and solve for x
6x= 30
x=5

supplementary means that the angles add to 180, so solve the equation 6x+60+90=180. 6x=30 x=5

1 gallon minus 1 quart, 1 pint, and 1 ounce

Answers

1 gallon minus 1 quart, 1 pint, and 1 ounce.

The smallest unit is the ounce. We need to know the number of ounces there are in 1 gallon, 1 quart, and 1 pint

1 gallon = 128 ounces
1 quart = 32 ounces
1 pint = 16 ounces

128 oz - 32 oz - 16 oz - 1 oz = 79 oz

There are 79 ounces left from the initial 1 gallon.

79 oz * 1gal/128 oz = 79 gal/128 = 0.617 gallon

A recycle machine crushes 175 pounds of cans in 5 minutes. How many pounds of cans will the machine crush in 16 minutes?A) 560
B) 955
C) 1,925
D) 2,805

Answers

x = pounds of cans crushed

*use similar ratios

(175 lbs)/(5 min) = (x)/(16 min)

*find x by multiplying both sides by 16

x = (175 lbs)/(5 min)*(16 min) = 560 lbs

so . . . the answer is . . . A) 560

The answer will be A) 560 because when you divide 175 by 5 is with be 35 then multiply 35 by 16 that will give you 560. Your welcome :)

The diagonal of a TV set is 52 inches long. It's length is 28 inches more than the heigh. Find the dimensions of the TV set.

Answers

The diagonal makes a triangle. Pythagorous means that 52^2=L^2+w^2. 52^2=2704. 2704/2 is 1352. The square root of this is 36.77 inches. If you add 14 onto one and minus 14 from the other (because 14+14=28) you get 50.77 inches (the width) and 22.77 inches (the height).
