Answer:
236 cm^2
Step-by-step explanation:
Formula
Area = sector angle/360 * pi * r^2
Givens
Sector angle = 120
r = 15
Solution
Area = 120/360 * 3.14 * 15 * 15
Area = 1/3 * 3.14 * 225
Area = 235.5
Area = 236 cm^2
This can be calculated easily.
As any two digit number can be written in the following form:
N= 10x +y
If we reverse the number now, it would become:
N' = 10y + x
So if we subtract one from the other, we should obtain 18 ( as mentioned in the question ).
N-N'= 18
=> x-y = 2
Thus, any number whose digits differ by two would be an aswer to the question.
The only numbers which satisfy this are : 13,24,35,46,57,68,79
But this would not be true for any 3 or more digit number.
Answer:
graph{x^2+2x+1 [-10, 10, -5, 5]}
Explanation:
This is a quadratic equation so it makes a Parabola on a graph.
Information:
x-intercept: (1,0)
y-intercept: (0,1)
vertex: (1,0)
line of symmetry: x=1
Answer:
Cost of confetti per ounce = $0.75
Step-by-step explanation:
Cost of 1 pound of confetti =$12
1 pound = 16 ounces
So, cost of 16 ounces of confetti is same as cost of a pound of confetti = $12
Using unitary method to find cost of 1 ounce of confetti.
if 16 ounce cost = $12
then 1 ounce will cost 
∴ Cost of confetti per ounce = $0.75
