Jerry walked a dog from 6:40 am to 7:30 pm one day. If he was paid at the rate of 6$ per hour, how much did he earn that day?
Tom [10]

Answer:

$5

Explanation:

Since Jerry walked the dog from 6:40am to 7:30am, the total minutes that he walked the dog was 50 minutes. Also a note, an hour is 60 minutes.


Since he is paid at a rate of $6 per 60 minutes, we can make a proportion.

   660=x50


From here, you have to solve for x. So cross multiply, and then simplify.

   60x=50⋅6

   60x60=50⋅6/60

   60x60=50⋅6/60

   x=5⋅6/6

   x=5

So the answer is $5.

What is 2/5% of 820?<br><br> 1.8<br><br> 2.05<br><br> 2.88<br><br> 3.28
Margarita [4]

Answer:

D) 3.28

Step-by-step explanation:

820/x=100/2.5

(820/x)*x=(100/2.5)*x       - we multiply both sides of the equation by x

820=40*x       - we divide both sides of the equation by (40) to get x

820/40=x

20.5=x

x=20.5

now we have:

2.5% of 820=20.5
