an air conditioning system can circulate 360, cubic feet of air per minute. how many cubic yards of air can it circulate per min
ahrayia [7]

Alright, lets get started.

3 feet = 1 yard

If we cube both sides of the equation, we will get the conversion into cubic yards

So,

3*3*3 cubic feet = 1 * 1*1 cubic yards

27 cubic feet = 1 cubic yards

So, 1 cubic feet = \frac{1}{27} cubic yards

So, 360 cubic feet = 360 *\frac{1}{27} cubic yards

So, 360 cubic feet = 13.33 cubic yards

13.33 cubic yards of air can it circulate per minute. : Answer

Hope it will help :)

95141 1404 393

Answer:

  b.  28,300

Step-by-step explanation:

The estimated number of 11th grade students in the state is ...

  (1600 classes)(27 students/class) = 43,200

About 34.6% are estimated to have 2 or more siblings, so the remaining 100%-34.6% = 65.4% are estimated to have fewer than 2 siblings.

Translated to a number of students, that percentage is ...

  0.654 × 43,200 = 28,252.8 ≈ 28,300

A good estimate of the number of students with fewer than 2 siblings is 28,300.

Between 10 P.M. and 7:54 A.M.​, the water level in a swimming pool decreased by 11/40 . Assuming that the water level decreased
xxMikexx [17]

Answer:

It approximately dropped 0.027777 per hour.

Step-by-step explanation:

First, we calculate the decrease.

Decrease = 11/40 = 0.275

Then,  we calculate the time interval.

From 10 pm to 7:54 hours will be 9.54 hours

Time interval= (9 + 54/60) hours

Time interval=9.9 hours

Finally, we calculate how much it dropped each hour

0.275/9.9 ≈ 0.027777

So it approximately dropped 0.027777 per hour.
