Hi !

Judy built a rectangular patio that is 9 meters wide and has a perimeter of 40 meters what is the length of Judy’s patio ?

$l=9\;m\\L=x$

$So\;Perimeter=2(9+x)=18+2x=40\;m\\\\18+2x=40\\2x=40-18\\2x=22\\\\x=\dfrac{22}{2}\\\\\boxed{x=L=11}$

The lenght of Judy's Patio is 11 meters.

Malik earned $2,344.55 fixing computers. He charged $35.50 per hour. Which expression does NOT use appropriate compatible number

meriva

Answer:

A, B , C do NOT use appropriate compatible numbers to estimate the total number of hours he worked.

Step-by-step explanation:

Malik earned $2,344.55

Wages per hour $ 35.50

No of hours = Total wages / wages per hour= $2,344.55/ 35.50 = 66.043

Lets analyze all the options

A. 2,400 ÷ 30= 80

B. 2,400 ÷ 40= 60

C. 2,000 ÷ 40= 50

D. 2,000 ÷ 30= 66.67

A, B , C do NOT use appropriate compatible numbers to estimate the total number of hours he worked.

Only D uses appropriate compatible numbers to estimate the total number of hours he worked.

Mr. Shaffer bought a block of fudge that weighed 8 3/4 pounds. He shared 2.45 pounds with his friends. How much does he have lef

Zinaida [17]

Answer:

6.3 or 6 3/10 pounds

Step-by-step explanation:

First you convert 8 3/4 into a decimal.

8 3/4 = 8.75

You then subtract 8.75 and 2.45.

8.75 - 2.45 = 6.3

6.3 as a fraction is 6 3/10

Therefore, he has 6.3 or 6 3/10 pounds of fudge left.

Hope this helps:)
