Answer: $115.01
Explanation:
First we have to find out the what 18 percent of tip is. So, multiply 97.45 by 0.18, and you’ll get 17.56. 17.56 is the 18 percent tip. However, the question asks for the total amount the family will pay, so add their bill with the tip. 97.45 + 17.56 = 115.01
From the above problem, we
can create the equation:
P = 245 + 20 t
where P is the total payment that
Johnny receives and t is the total time he worked
Given that P = 2245, so find for
t:
2245 = 245 + 20 t
t = 100 hours
Answer: The volume of the cone is 130 cubic centimeters.
Step-by-step explanation:
We know that to find the volume of a cylinder you will use the formula
V= Where r is the radius and h is the height.
And to find the volume of a cone you will use the formula
V= *h /3
So if they have the same dimensions which is the height and the radius then we will just divide the volume of the cylinder by 3 to find the volume of the cone.
V = 390/3
V = 130 cm^3
