Chris can do 30 pushups in 60 seconds. At this rate<br> how many pushups can he do in 360 seconds?

Y_Kistochka [10]

Answer: 180 pushups

Step-by-step explanation: First set up a proportion. The proportion would be 30 pushups over 60 seconds equal x over 360 seconds. Then you would cross multiply which is 60 times x which is 60x .After that do 30 times 360 which is 10,800.Now you have 60x = 10,800.NOw divide both sides by 60 which gives you 180 as x.

A B C D E Confirm Supplies for last year cost $1,477, which was $177 over budget. Rounded to the nearest 1%, by what percent did

Paha777 [63]

It would be over 12% (11.98375085%)

Lets break it down:

You need to find what percent 177 is of 1,477.
To do this, you need to do 177÷1,477 to get 0.1198 and so on

(To find a percent from a decimal, you move the decimal point 2 places to the right)

If you find the percent, it would be 11.98 (and so on) percent. Rounded to the nearest 1%, it would be 12%

Hope this helps!
