You would put # of people x BTUs x # of hours over cubic feet
12 x 400 x 5 / 18 x 38 x 12
the answer is 2.9 BTUs/ft^3
Answer:
There are an infinite number of solutions to this equation. One of which would be (-2, -1)
Step-by-step explanation:
In order to find any solution, start by picking a value for x. For the purpose of this exercise, we'll select -2. Now input that in for x and solve for y. The resulting ordered pair is a solution.
4x - 7y = -1
4(-2) - 7y = -1
-8 - 7y = -1
-7y = 7
y = -1
Answer:
Proportional: second and third, non-proportional: first and fourth
Step-by-step explanation:
Proportional relationships are linear functions that pass through the origin. Using this definition, we can conclude that the proportional relationships are the second and third options whereas the non-proportional relationships are the first and fourth options.
Theres only 4 but the answer is -15
1.
5u - 2u = 3u (diff. between longest and shortest)
3u = 87cm
1u = 87cm ÷ 3 = 29cm
5u + 4u + 2u=11u
11u = 11 x 29cm = 319cm
Ans: 319cm
2.
9u = 1350
1u = 1350 ÷ 9 = 150
6u + 5u = 11u
11u = 11 x 150 = 1650
Ans: 1650
