Answer:
7.069 ft²
Step-by-step explanation:
Given that:
Shape of rug = circular
Diameter of rug = 3 feets
The Area in square feet of the rug =?
Area of a circle :
πr²
r = Radius
r = diameter / 2 = 3 /2 = 1.5 feets
Area = π * 1.5^2
Area = 7.0685834
Area = 7.069 ft²
Answer:
30+(2x+7)+63=180(sum of angles of triangle )
30+2x+7+63=180
2x+100=180
2x=180-100
x=80/2
x=40
Answer:
Cost of one pencil: 
Cost of one eraser: 
Step-by-step explanation:
Let be "p" the cost in dollars of one pencil and "e" the cost in dollars of one eraser.
Based on the information given in the exercise, you can set up the following system of equations:

You can use the Elimination Method to solve the system of equations.
Multiply the first equation by -3 ad the second one by 4. Then add the equations and solve for "e":
{
Substitute the value of "e" into any original equation and solve for "p":
