Answer:
<em><u>C</u></em>
Step-by-step explanation:
if h<28
- its area= 28×28 = 784, but it is greater than 15 sq inches
- Its volume = 28×28×28 = 21952, but it is greater than 285 cubic inches
hence h must be less than 28 (h<28)
And not greater than √15 ( h<√15)

Answer:
7 1/3 hours
Step-by-step explanation:
We are to assume that the total number of heater-hours required is a constant. That is, the time is inversely proportional to the number of heaters.
If the number of heaters goes up by a factor of 6/4 = 3/2, then the number of hours will go down by the inverse factor: 2/3.
With 6 heaters instead of 4, the time required is (2/3)(11 hours) = 7 1/3 hours.
Substitute the x values back into the equation
(1, 22)
(2, 18)
(3, 14)
(6, 2)
Answer:
y = 0 and z = 5
Step-by-step explanation:
the denominator of the expression cannot equal zero as this would make the expression undefined Equating the denominator to zero and solving gives the values that y and z cannot be
solve y(z - 5) = 0
equate each factor to zero and solve
y = 0 ← excluded value
z - 5 = 0 ⇒ z = 5 ← excluded value
