The distance between two points on the circumference of a circle is called the arc. If the arc length subtends an angle θ to the center of the circle and the circle has a radius r, then the length of the arc is calculated by the formula;
θ/360 × 2πr.
Answer:
179 minutes
Step-by-step explanation:
You can write an equation to represent the cost of the rental, and then you can solve the equation to find the number of hours.
Let m = number of minutes.
The total cost is the cost per minute plus the fee to start.
1 minute costs $0.12.
2 minutes cost $0.12 * 2
x minutes cost $0.12 * x, or simply 0.12x.
The fee to start is $2, so the total to rent for m minutes is 0.12m + 2.
The equation
c = 0.12m + 2
gives you the cost, c, for a rental of m minutes.
We are told the total cost was $23.48. Replace c with 23.48, and solve for m, the number of minutes.
23.48 = 0.12m + 2
Switch sides.
0.12m + 2 = 23.48
Subtract 2 from both sides.
0.12m = 21.48
Divide both sides by 0.12
m = 21.48/0.12
m = 179
Answer: 179 minutes
Answer:
72
Step-by-step explanation:
Given that:
P(Red) = Probability of randomly choosing a red
Probability of randomly choosing a red = 7/12
Number of red marbles = 42
The number of marbles in the bag :
P(Red) = number of red marbles / total number of marbles
Total number of marbles = (red marbles + blue marbles)
P(red) = 7/ 12 ;number of red = 42
P(Red) = number of red marbles / total number of marbles
Let:
x = total number of marbles
7/12 = 42 / x
(7/ 12)x = 42
7x / 12 = 42
7x = 12 * 42
7x = 504
x = 504 / 7
x = 72
