8% sales tax is 8% of the sales price = 8% of 's'
8% of 's' = 0.08 × s = 0.08s
The total price = s + 0.08s ⇒ this is the expression
Answer:
5625in²
Step-by-step explanation:
Area of the plate = πr²
625π = πr²
625 = r²
r = √625
r = 25in
If the radius of the plate is tripled, then the new radius will be 3(25) = 75in
New Area = π(75)²
New Area = 5625π in²
If the radius is tripled, the new area of the plate is 5625in²
Draw a diagram! Lets say the width is x, then the length must be 2x.
Area = length x width
2x x x = 8sq meters
2x^2 = 8
x^2 =4
x = √4
x = 2
we found the width the length is two times the width, making it 4 meters.
Answer:
x=0, -5/3
