C = 5, -7
Answer:
1. total volume of box=2.5(V)D
2. 7 Drawers
Step-by-step explanation:
2.5 = V
so 1 draw = 2.5 cubic inches of volume
so V(2.5) × D(number of drawers) = total volume of drawers in the box
Answer:
4 feet on each side.
Step-by-step explanation:
Given :
Width of the wall = 11 feet
Width of the window = 3 feet
Now for the window to be placed in the center of window :


= 4 feet
Therefore, in order to place the window on the center of the wall, 4 feet space must be there on each side of the window.
Answer:
∠B = 60°
a = 4.0 units
b = 6.9 units
Step-by-step explanation:
The triangle is right angled. The sum of all angles of a triangle is equal to 180 degrees.
The 3 angles are 90, 30 , ∠B .
<em>
</em>
Thus, B = 180 - 120 = 60 degrees
by trigonometry,
sin(30) =
= 0.5
a = (8)(0.5) = 4 units
Also,
cos(30) =
= 0.866
b = (8)(0.866)= 6.928
Same solution.
volume = 1/3(8x6)(5) = 16x5 = 80cm^3
answer: 80cm^3
