To solve for this, simply add the values of people who prefer walking shoes and running shoes, since they are NOT tennis shoes.
runningshoes+walkingshoes=
6+9=15
Answer=D
Answer: Option 'B' is correct.
Step-by-step explanation:
Annual salary of her = $14700
Monthly salary would be
She wants to purchase new things after spending on expenses and save money for her college classes.
According to options :
We can consider Budget B and D as the monthly salary is correct in these budgets only, i.e. $1225.
In Budget B,
Total money she saved = $400
In Budget D,
Total money she saved = $400
So, Budget B is the best which helping meet her goals.
Hence, Option 'B' is correct.
The $378.49 was earned on the investment if the principal amount of $3000 is invested for 3 years at 4% compounded semi-annually.
<h3>What is compound interest?</h3>
It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We can calculate the compound interest using the below formula:
Where A = Final amount
P = Principal amount
r = annual rate of interest
n = how many times interest is compounded per year
t = How long the money is deposited or borrowed (in years)
Here,
P = $3000
r = 4% = 0.04
n = 2
t = 3 years
After plugging all the values in the formula:
After solving:
A = $3,378.49
I = A - P = 3,378.49 - 3000 = $378.49
Thus, the $378.49 was earned on the investment if the principal amount of $3000 is invested for 3 years at 4% compounded semi-annually.

<u>Answer:</u>
If the circumference of a circle is changed from 9 cm to 3 cm, then the diameter decreases by a factor of 3.
<u>Solution:</u>
Given, the circumference of a circle is changed from 9 cm to 3 cm,
We have to find how will the diameter change from the given equations?
We know that, diameter = 2 radius and circumference = 2π radius.
Hence, the diameter decreases by a factor of 3.
