4/9 ÷ x = 12
u always do the opposite, in an equation/inequality.
multiply 4/9 on both sides.
4/9 * 12/1 = 48/9
so it's 48/9
Answer:
The area of the cover for the hot tub must be:
Step-by-step explanation:
First, you must understand that since a hydromassage tub is mentioned and the diameter, it is assimilated that it is round in its upper part, which is why the formula is used to find the area of a circle:
- <u>Area of a circle = pi * radius ^ 2</u> (you must know that the radius is half the diameter)
Since the diameter is mentioned, it can be replaced in the formula:
- Area of a circle = 3.14 * (3.5 feet) ^ 2
- <u>Area of a circle = 38,465 square feet. Approximately 38 square feet</u>.
Answer:
32
Step-by-step explanation:
ok if it was a normal rectangle =
8 x 6
but the middle part takes 4 from the middle
since there are 2 rectangle
4/2 = 2
since there are lines
6 x 2 = 12 + another 12 since the rectangle on the bottom is the same as the top
24 + ...
6 - 4
2 x 4 = 8
24 + 8 =
32
Answer: area
Step-by-step explanation:
Area is solved with L * W
Volume is solved with L * W * H
Using these formulas we can see that area uses 2-dimensions, the length and the width, while volume uses 3.
