Step-by-step explanation:
It is given that, an air conditioning system can circulate 320 cubic feet of air per minute. We need to find how many cubic yards of air can it circulate per minute?
1 yard = 3 foot
1 feet = (1/3) yard
320 feet = 106.66 yard
![320\ \text{feet}^3=320\times( \dfrac{1}{3})^3\ \text{yard}^3\\\\=11.85\ \text{yard}^3](https://tex.z-dn.net/?f=320%5C%20%5Ctext%7Bfeet%7D%5E3%3D320%5Ctimes%28%20%5Cdfrac%7B1%7D%7B3%7D%29%5E3%5C%20%5Ctext%7Byard%7D%5E3%5C%5C%5C%5C%3D11.85%5C%20%5Ctext%7Byard%7D%5E3)
So, it will circulate 11.85 cubic yard of air per minute.
H= 445.36
because you bring the 86.43 over to the 531.79. which would make 86.43 a negative number. so you subtract 531.79 by 86.43
What you gotta take from this problem:
What Joe got during break =
![2t+2](https://tex.z-dn.net/?f=2t%2B2)
What his sister gave him =
![3t](https://tex.z-dn.net/?f=3t)
What he has total = 10 tadpoles.
Now to assemble this equation:
![2t+2+3t=10](https://tex.z-dn.net/?f=2t%2B2%2B3t%3D10)
Now combine like terms to get
![5t+2=10](https://tex.z-dn.net/?f=5t%2B2%3D10)
Subtract 2 on each side of the equation to get
![5t=8](https://tex.z-dn.net/?f=5t%3D8)
Now you would divide 5 on each side and get
![t=1.6](https://tex.z-dn.net/?f=t%3D1.6)
, however since you can't have a .6 of a tadpole, you would have to round it up to 2.
Answer:
1 and 6
Step-by-step explanation:
1 + 6 = 7
1 x 6 = 6
The formula for the area of a rectangle is:
![A=wl](https://tex.z-dn.net/?f=A%3Dwl)
w = width
l = length
First, we have to convert 2
![\frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20)
into an improper fraction, then into a number. The improper fraction would be
![\frac{5}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5%7D%7B2%7D%20)
. Let's convert that into a decimal.
![5/2=2.5](https://tex.z-dn.net/?f=5%2F2%3D2.5)
Let's multiply
![2.5*10=25](https://tex.z-dn.net/?f=2.5%2A10%3D25)
The area of the rectangle would be 25 feet!
