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:
She walked neighbor's dog 4 times.
Step-by-step explanation:
It is given that:
Peri earned $27 for walking the dogs 3 times.
Unit rate = 
Unit rate = $9 per dog
Now,
Peri worked at the same rate and earned $36.
Unit rate = 
d= 36/9
d = 4
Therefore,
She walked neighbor's dog 4 times.
Step-by-step explanation:
We want to find how many miles per minute Joe runs. This means, we need to simplify the equation:
so that the number on the bottom is 1. How do we do that?
Simple.
Just divide 12 / 84
Answer:
Joe runs approx. 0.143 miles per minute.
P - (-3) would turn into p+3.
So we have
p - (-3) = 2
become
p + 3 = 2
To isolate p, we need to move that "+3" over. To do this, we subtract 3 from both sides. Subtraction is the opposite (or inverse) of addition, which is why this works
p+3 = 2
p+3-3 = 2-3 ... subtract 3 from both sides
p+0 = -1
p = -1
So the final answer is p = -1
