11/30 bags of mulch is needed.

<u>Step-by-step explanation:</u>

We have to find the number of bags of mulch.

7 (1/2) sq. yards need 2(3/4) bags of mulch.

So one sq. yd need 2(3/4) / 7(1/2)

We have to change the mixed fraction into improper fraction and then dividing them we will get the answer.

2(3/4) = ((2×4)+ 3)/4 = (8+ 3)/4 = 11/4

7(1/2) = ((7×2)+1)/2 = (14+1)/2 = 15/2

11/4 ÷ 15/2

It change into multiplication as,

11/4 × 2/15 = 11/30 bags of mulch is needed.

The cost CC (in dollars) of making nn watches is represented by C=15n+85C=15n+85. How many watches are made when the cost is $38

dangina [55]

$\bf \stackrel{cost}{C}=15\stackrel{watches}{n}+85\qquad \boxed{C=385}\qquad \stackrel{cost}{385}=15n+85
\\\\\\
380=15n\implies \cfrac{380}{15}=n\implies \cfrac{76}{3}=n\implies 25\frac{1}{3}=n$

so, 25 whole watches and hmmmm just the wristband of another maybe.

There were 60 runners to start the race. In the first half of the race,1/3 of them dropped out. In the second half of the race,1

Verizon [17]

In the question, it is already given that the total number of runners in the race is 60 and out of them 1/3 dropped out in the first half. In the second half 1/4 of the remaining runners dropped out.
Now
Total number of runners in the race = 60
Number of runners that dropped out in the first half = 1/3 * 60
   = 20
Number of runners remaining = 60 - 20
   = 40
Number of runners dropping out in the second half = 40 * 1/4
   = 10
Then the number of runners that finished the race = 40 - 10
   = 30
Then 30 runners completed the race.
