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:
Step-by-step explanation:
6x + 2y = 12 Subtract 6x from both sides
6x-6x+2y = -6x+12 Combine
2y = -6x + 12 Divide all parts of the equation by 2
2y/2 = - 6x/2 + 12/2
y = - 3x + 6
Slope = - 3
y intercept = 6
Answer: 57%
Step-by-step explanation:
Davis's monthly expenditure and his monthly salary was 3 : 7.
This means that for every $7 he received, he spent $3 out of it.
The amount he saved is therefore:
= 7 - 3
= $4
For every $7 received, he saved $4.
Percent = 4/7
= 57%
For example,
write 3 5/4 in simplest form.
3*4+5=12+5=17
17/4 is in simplest form.
