$15 x .0725 = 1.0875 which we have to round to $1.09
Notice how I changed the 7.25% to a decimal .0725 by moving it back two places.
3/5 = 3/y
40 = 3y
Divide both by 3
Answer= 13.3
Answer:

Step-by-step explanation:
The formula of a surface area of a sphere:

R - radius
We have

Substitute and solve for R:
<em>divide both sides by π</em>
<em>divide both sides by 4</em>

The formula of a volume of a sphere:

Substitute:

Answer:
Step-by-step explanation:
What i would do is multiply both sides by 2z + 1
so you get z-6=20z+10
-19z=16
z=-16/19
Answer:
a. $1.66
Step-by-step explanation:
We have been given that Health and Heart Club charges $259 per year. A person has 3 visits per week. We are asked to find the cost of per visit to Health and Heart Club.
We know that there are 52 weeks in one year. So total visits in one year would be 3 times 52 that
visits.
Now, we will divide total cost by 156 to find cost per visit.


Rounding to nearest hundredths, we will get:

Therefore, the cost per visit is $1.66 and option 'a' is the correct choice.
