Step-by-step explanation:
15 x (1/3+1/5) make common denominators and add
15 x (5/15+3/15) add fractions
15/1 x (8/15) 15 and 15 cancel out and become 1
1/1 x 8/1
1 x 8

Answer:
17662.5 sq. feet
Step-by-step explanation:
We know that the formula for Area of a Circle is
.
r = radius; d = diameter, which is r*2
And so, in the question, it gives you that the diameter is 150, first we divide it by 2 to get the radius.
150/2 = 75
The question said to keep
=3.14, so then we plug in the equation-

Then we use PEMDAS [Parenthesis; Exponents; Multiply & Divide; Add & Subtract] which would get us-
(first doing the Exponent)
And we continue-
(then multiple)
So our answer is-
17662.5 sq. feet
I hope this helps!

Answer:
d) r = -65.
Step-by-step explanation:
The absolute value of r represents the relationship strength and the sign represents the relationship direction
Also if the relationship is nearest to 1 then it would be termed as positive correlated and if the relationship is nearest to -1 then it would be termed as negative correlated
Therefore based on the given options, the last option is correct
