Answer:
$32.80
Step-by-step explanation:
Find out how much Nancy spent on 4 violins and 2 song books.
1 violin = 87.82
4 violins = 87.82 x 4 = 351.28
1 song book = 7.96
2 song books = 7.96 x 2 = 15.92
351.28 + 15.92 = 367.20
4 x 100 dollar bills = 400 dollars
Normally after paying for an item, if you pay much more money than the actual price of the item, you'll get some money back from the cashier. That's called a change.
400 - 367.20 = 32.80
<u>Answer:</u>
The sprinkler will cover 104.66 square feet
<u>Explanation:</u>
A water sprinkler covers a circular area with a diameter D= 20 feet
and radius r = 10 feet
Arc measuring degrees = 120 degree
Area of the Arc = 
= 
= 
= 104.66
The sprinkler will cover an arc area covering 104.66 square feet
Based on the information, there were initially 1200 ferns; the monthly percent rate of change is 68% and this situation is modeled by an exponential growth function
<h3>How to complete the information?</h3>
The given parameters from the question are:
P(n) = 1200(1.68)^n
Where
n represent the number of months
An exponential growth function is represented as:
P(n) = a * (1 + r)^n
Where
a represents the initial value
r represents the rate
By comparison, we have
a = 1200
1 + r = 1.68
This gives
r = 0.68 = 68%
Hence, there were initially 1200 ferns; the monthly percent rate of change is 68% and this situation is modeled by an exponential growth function

The answer is
B) same side interior angles
if you think about it, these angles help to form the straight line (which is 180 degrees)
hope this helps
