A rectangle sand box has a length of 5 1/3 feet and a width of 3 3/4 feet . what is the perimeter
taurus [48]
Perimeter is 18 1/6 feet.

Perimeter is solved by adding the length and width of the rectangle and multiplying the sum by 2.

P = 2(l + w)

length = 5 1/3 ⇒ (5*3)+1/3 = 16/3
width = 3 3/4 ⇒ (3*4)+3/4 = 15/4

In adding fractions, make sure that the denominators are the same. Both 3 and 4 are factors of 12. So, we need to multiply each fraction to get 12.

16/3 * 4/4 = 64/12
15/4 * 3/3 = 45/12

Length + Width = 64/12 + 45/12 = (64+45)/12 = 109/12 

P = 2 * 109/12
P = 218/12
P = 18 2/12 ⇒ 18 1/6 feet

brian, tim and kenny got paid a total of $240 for mowing neighborhood lawns . They split the money in the ratio of 5:9:10 . how
Yuliya22 [10]

Answer:

$50 for Brian

$90 for Tim

$100 for Kenny

Step-by-step explanation:

Let 5x = amt for Brian

     9x = amt for tim

     10x = amt for ken

5x + 9x + 10x = 240

24x = 240

x = 10

5x = 5(10) = $50 for Brian

9x = 9(10) = $90 for Tim

10x = 10(10) = $100 for Kenny
