12+28+40+12=52
Perimiter =52ft
Yards=3 feet
52ft/3 is about 17.34yards
Now multiply yards by cost
17.34 x 15=260$
It costs 260 for titles to be put around the pool
C. 3, would be the greatest.
to isolate k, you have to divide 3/2 by 9/10. you will then get 5/3
Answer:
Yes, the sides form a right triangle.
Step-by-step explanation:
<u>Pythagorean Theorem:</u>
a² + b² = c²
↓
20² + 21² = 29²
║a² = 20² = 400
║b² = 21² = 441
║c² = 29² = 841
↓
400 + 441 = 841
║This equation is true.
↓
Yes, the sides form a right triangle.
For this case, the first thing we must do is define variables.
We have then:
x: cost of each bag of popcorn
y: cost of each drink
writing the system of equations we have:
9x + 9y = 117
x + 3y = 23
Solving the system of equations we have:
x = 8 $
y = 5 $
Answer:
a system of equations that can be used to find the price of one bag of popcorn and the price of one drink is:
9x + 9y = 117
x + 3y = 23
The price of a bag of popcorn is $ 8.
