25.2 m/min because 42*(60/100) = 25.2
Answer:
≈ 7 hours
Step-by-step explanation:
Maria can do full job in 13 hours,
she can do 1/13 part of job in one hour
Felipe can do full job in 15 hours,
he can do 1/15 part of job in 1 hour
Together they can do:
- 1/13 + 1/15= 28/13*15= 28/195 of job in 1 hour
to complete full job they need:
- 1 ÷ 28/195= 195/28 ≈ 7 hours
The ratio shown in fraction form would be;
Now to convert it to its simplest form, you need to find their greatest common factor; (so in this case it would be 28...cause 28 goes into 56 evenly)
*Now divide both terms by
28
28 ÷ 28 =
1
56 ÷ 28 =
2
so your ratio 28 to 56 in simplest form is..
Hope this helps :)
Answer:
The lateral area of the pipe is 942 sq ft.
Step-by-step explanation:
A pipe can be modeled as a cylinder prism.
The lateral area of a cylinder prism can be expressed as the product of the length by the perimeter of the section.
We start by calculating this perimeter.
As the diameter is 25 ft, the perimeter of the section can be expressed as:
Then, to know the lateral surface we multiply this perimeter by the length of the pipe (12 ft):
The lateral area of the pipe is 942 sq ft.
3 boxes of paper cost 3*21.99=65.97, 2 toner cartridges cost 2*52.90=105.8.
Given that there's 20% off for all office supplies, then 3 boxes of paper cost 3*$21.99*0.8=$52.78,
2 toner cartridges cost 2*$52.90*0.8=$84.64, the price of folder is $0.99*0.8=$0.792.
So, after buying these things given that there's 20% off for all office supplies, he will have only
$175-$52.78—$84.64= $37.58.
As 37.58/0.792=47.45, hence he can buy only 47 folders
Answer is 47
