7y. the 7x cancels out and if u distribute, it's 7y.
The domain of C = All positive real numbers
The given relationship is:
C = 20W
where:
W represents the weight of the letter in ounces
C represents the cost of sending the letter in cents
The domain of a function is a set of all the input values.
In the function C = 20W, the weights (W) represent the input values.
Since the weight of a letter cannot be negative, it can only contain positive real numbers (Both integers and decimals)
Therefore, the domain of C is a set of all positive real numbers

<u>Given</u>:
Given that the radius of the sphere is 9 cm
We need to determine the volume of the sphere.
<u>Volume of the sphere:</u>
Let us determine the volume of the sphere.
The volume of the sphere can be determined using the formula,
where r is the radius of the sphere.
Substituting r = 9 in the above formula, we get;
Thus, the volume of the sphere is 972π cm³
Hence, Option B is the correct answer.
The answer is 105 4/61
If you do the long division correctly, you will get 105 and all you have is 4 left.
Since you are dividing by 61, you do 4/61.
So that is how you get 105 4/61
I hope this helps!
Answer:
C = 28.048
Step-by-step explanation:
Circumference = 2pi(r)
Area = pi(r)^2
62.6 = pi(r)^2
r^2 = 62.6/pi
r^2 = 19.926
r = 4.464
Therefore, circumference = 2pi(4.464)
= 28.048
