Answer:
2) -7 i think
Step-by-step explanation:
Answer: B) 4 BTUs/ft^3
Step-by-step:
For a cuboid of length L, width W and height H, the volume is:
V = L*W*H
In this case, we have:
L = 20ft
W = 15ft
H = 10ft
Then the volume of the room is:
V = 20ft*15ft*10ft = 3000 ft^3
Now we have 6 people, and each generate 400 BTUs per hour.
Then in total, they generate:
6*400 BTUs per hour
2400 BTUs per hour.
Now we want to find the BTUs per ft^3 produced in 5 hours.
Then if they generate 2400 BTUs per hour, in 5 hours they generate a total of:
5*2400 BTUs = 12000 BTUs
Now we take the quotient between the total BTUs and the volume of the room:
Q = (12000 BTUs)/(3000 ft^3) = 4 BTUs/ft^3
The correct option is B.
his allowance is $14
to find this you:
11-4=7
7*2= 14
The 11 is what he had the four is what he was given extra and the multiplied by two is because he spent half of his money at the candy store
When you are dividing like terms with exponents
1. True - T looks to be centered between A & M
2. True - opposite angle equal each other and H is the midpoint of each angle
3. True - complementary angles = 90 degrees and the two outside lines look like they represent a right angle
( 3 may be false, since they usually have a little square in the corner of a right angle and this picture doesn't, but it looks like one though)
