Answer:
C. 2,940 ft³
Step-by-step explanation:
The building is composed of a triangular prism and a rectangular prism
Therefore,
Volume of air in the building = volume of the triangular prism + volume of the rectangular prism
Volume of triangular prism = ½*bhl
b = 4 yards = 4*3 = 12 ft
h = 15 - 9½ = 5½ = 5.5 ft
l = 20 ft
Volume of triangular prism = ½*12*5.5*20 = 660 ft³
Volume of rectangular prism = W*H*L
W = 4 yds = 12 ft
H = 9½ = 9.5
L = 20 ft
Volume of rectangular prism = 12*9.5*20 = 2,280 ft³
✔️Volume of air in the building = 660 + 2,280 = 2,940 ft³
Answer:
The 2 numbers are 13 and 23
Step-by-step explanation:
If 2 numbers are x and y we have:-
x + y = 36
x - y = 10
Adding:-
2x = 46
x = 23
So y = 36 - 23 = 13
Answer:
2X - Y + 3Z
Step-by-step explanation:
Combine like terms. Like terms are terms that have the same variable part.
6X + 5Y − 2Z − 4X − 6Y + 5Z =
= 6X - 4X + 5Y - 6Y - 2Z + 5Z
= 2X - Y + 3Z
Answer:
12
Step-by-step explanation:
21x + 4x = 300 Put brackets around the first two terms.
(21x + 4x) = 300 Pull the x outside the brackets. Use the distributive property. Combine the left
25x = 300 Divide by 25
25x/25=300/25 Do the division
x = 12
