the area of a rectangular sandbox is 56 2/3 square feet.The length of the sandbox is 8 1/2 feet. What is the width?

Answers

Answer:

6 and 2/3

Step-by-step explanation:

56 and 2/3 divided by 8 1/2

Rewrite the mixed numbers as a fractions greater than 1.

56 and 2/3 divided by 8 and 1/2 = 170/3 divided by 17/2.

Rewrite the problem as a multiplication using the reciprocal of the divisor.

170/3 divided by 17/2 = 170/3 x 2/17

= 170 x 2

3x17

cross out 170 to 10. Then cross out 17 to 1.

= 20/3, or 6 an 2/3

Divide 56 2/3 by 8 1/2 and that will give you your answer. Check to make sure it right by multiplying the answer you get with 8 1/2 and it should be 56 2/3.

The measure of an angle is three more then twice its supplement. What is the measure of the angle?

Answers

Answer:

121 degrees.

Step-by-step explanation:

If the angle is x degrees then its supplement is 180-x degrees.

So we have the equation:

x = 2(180-x) + 3

x = 360 - 2x + 3

3x = 363

x = 121.
