(printer cost) = 0.20 * (savings)
(printer cost)/0.20 = (savings)
savings = 5*(printer cost)
Whatever the cost of the printer was (information not supplied here), Corey's savings was 5 times that amount.
Step-by-step explanation:
Radius is half of the diameter
Circumference is 2*pi*radius
Area is pi*radius^2
So r (radius)= 10.3
C (circumference)=64.72
and A (area)=333.29

Since there is 101 Tickets,
Let S + A = 101
1.50S + 2.50A = $186.50
Adults + Students = 101
$186. 50 = $2.50 Adults + $1.50 Students
Answer is 35 Adults, and 66 Students.
Hope that helps!!!
Answer:
$0.558
Step-by-step explanation:
The expected value is the sum of the value of each outcome times the chance that it happens. In this case, there are two outcomes:
- Win $31 million
- Win $0
Then our expected value can be calculated as:
Answer: 22.5 degrees
Step-by-Step Explanation:
As we can see, we are given a line, which is a straight angle. Hence, it will be of 180 degrees.
=> All the angles sum up to 180.
Therefore,
=> 3x + x + 90 = 180
= 4x + 90 = 180
= 4x = 180 - 90 = 90
=> x = 90/4 = 22.5
Therefore, x = 22.5 degrees
Verification:
=> 3x + x + 90 = 180
= 3(22.5) + 22.5 + 90 = 180
= 67.5 + 22.5 + 90 = 180
= 90 + 90 = 180
=> 180 = 180
=> LHS = RHS
