Answer:
Answer : 100^3
Step-by-step explanation:
formula to find volume of prism =
v = base area * height
v = 20 * 5
v = 100
so , volume is 100^3
First find the length of the room by dividing the area by the width:
99 / 9 = 11
2 walls would be 9 feet and 2 walls would be 11 feet.
Perimeter is the sum of the 4 walls:
11 + 11 + 9 + 9 = 40 feet
The answer is the option b. 1.
Two sides and one angle determine one unique triangle.
If the angle is the between the two sides, you just can use the rule known as SAS, Side Angle Side.
When that is the case you use the cosine rule.
When the known angle is not between the two sides but one of the others, you use sine theorem.
Then in any case when you know two sides and one angle of a triangle the other side and angles are determined, which implies that there is only one possible triangle.
Answer:
2 gallons
Step-by-step explanation:
2 gallons of paint
Explanation:
If 3/4 of a gallon covers 2/5 of a wall, this means that a half of 3/4 gallons can cover 1/5 of a wall.
By knowing this, you can just make up your own expression
(the trick is to find a way to break it down to one, so you can multiply and manipulate it to save yourself some brain cells)

since we're talking about real life it would be 2 gallons of paint instead of 1.875 gallons to paint the whole wall
Hope this helps!
