Answer:
expression: (30/t) - 10
evaluation: 30/2 - 10 = 5
Step-by-step explanation:
So what you are trying to find is the certain amount of children tickets and adult tickets. the final amount is a total of $12. This means that a unknown number of children tickets (c) times 1.50 (price of each ticket for children) plus the unknown number of adult tickets (a) times 4.00 (price of each ticket for adults) equals a final cost of $12.00.
Equation: 1.50c+4.00a= 12.00
Answer:
The perimeter or circumference of a half mirror = 37.68 cm
Step-by-step explanation:
- The diameter of circular measure = 24 cm
We know that the perimeter of a circular shape is called the 'circumference', with the formula
- Circumference of a circle = C = 2πr
When the mirror is cut into half, the diameter gets half as well.
- Thus, the diameter of a half mirror = 24/2 = 12 cm
We know that radius = r = diameter / 2 = 12/2 = 6 cm
Thus, the perimeter of half of the mirror = C = 2πr
= 2(3.14)6
= 37.68 cm
Therefore, the perimeter or circumference of a half mirror = 37.68 cm
Its the first one. I typed them all in my graphing calculator to check
