Jairo spent $40.18 on 3 music CDs.
Let’s solve for the original prices of each CDs.
=> The sales tax added is 2.33 dollars
=> 40.18 dollars – 2.33 dollars
=> 37.85 dollars
he used 1.00 dollar coupon during his purchase
=> 37.85 + 1.00 = 38.85 dollars
=> now, we need to divide this amount to 3 for 3 CDs
=> 38.85 / 3
=> 12.95
the cost of each CD is 12.95
Answer:
79
Step-by-step explanation:
A square that has side length
has area
.
A circle that has a diameter 20 feet has area ![A=\frac{\pi d^2}{4}](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B%5Cpi%20d%5E2%7D%7B4%7D)
We substitute the diameter into the formula to obtain;
![A=\frac{\pi \times 20^2}{4}=100\pi ft^2](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B%5Cpi%20%5Ctimes%2020%5E2%7D%7B4%7D%3D100%5Cpi%20ft%5E2)
The number of squares that has area 4 feet square that can fit into a circle with area
is
![=\frac{100\pi}{4}=25\pi=78.5398](https://tex.z-dn.net/?f=%3D%5Cfrac%7B100%5Cpi%7D%7B4%7D%3D25%5Cpi%3D78.5398)
When we round to the nearest whole number; we have 79 squares.
Answer:
35 2-point questions, and 15 5-point questions
Assume x 2-points question, so 50-x 5-points question
Total no of points: 2*x+5*(50-x)=145 points
2x+250-5x=145
-3x=-105
x=-105/-3=35 2-points questions
Remaining 50-35=15 5-points questions
ok so i really hope this helped and if it didn't then sorry
