Including the bus driver, there are 15 people on a bus. During the bus ride, each person produces 750 BTUs (British Thermal Unit
Alecsey [184]
This is the concept of applications of volume. We are required to calculate BTUs per cubic foot. This will be given by the formula:
(BTU)/volume
Total BTU=15*750=11,250
(assuming the bus is a perfect cuboid) volume of the bus will be;
volume=length*width*height
=38*8.5*6.25
=2018.75 ft^2
Thus the BTUs per foot will be:
11250/2018.75
5.57 BTUs/ft

If the product of two positive consecutive odd integers is 63, what’s the larger number ?
myrzilka [38]

For this case we have:

x: Let the variable representing the first odd number

x + 2: Let the variable representing the consecutive odd number at x.

According to the statement we have:

x (x + 2) = 63\\x ^ 2 + 2x = 63\\x ^ 2 + 2x-63 = 0

We found the solution by factoring:

We look for two numbers that, when multiplied, result in -63 and when added, result in 2. These numbers are +9 and -7.

9-7 = 2\\9 * (-7) = -63

Thus, we have:

(x + 9) (x-7) = 0

Therefore the solutions are:

x_ {1} = - 9\\x_ {2} = 7

We choose the positive value, so we have:

x = 7\\x + 2 = 7 + 2 = 9

Answer:

The largest number is 9
