Answer:
The third one, is the correct
Answer:
600 minutes
Step-by-step explanation:
Let's make the two equations equal to each other.
24 + .13x = .17x
Subtract .13x from both sides.
24 = .17x - .13x
24 = .04x
Divide by .04 on both sides to get the value of x.
24/.04 = 600
x = 600
Therefore, for 600 minutes of calls will the cost of the two phone plans be equal.
Step-by-step explanation: 85 is 56.67 percent of 150
56.67 percent of 2,400 is 1360 so 1360 people gave the play at least 4 stars
Answer:
28.27
Step-by-step explanation:
first you have to stablish the formula for the area of the circle, which is A=pi×radius square. Then, you have to substitute the variables and solve. the formula with the numbers plugged in would be A=3.14×3 square. Finally, solve by multiplying 3×3=9, so the formula would be 9×3.14, when multiplyed, your answer would be 28.27 if you round it.
Step-by-step explanation:
A sequence is defined recursively using the equation f(n + 1) = f(n) – 8. If f(1) = 100, what is f(6) ?
Since, A sequence is defined recursively using the equation f(n + 1) = f(n) – 8. If f(1) = 100,we have to find the value of f(6).
Consider
f(n+1) = f(n)-8
Let n =1, we get
f(1+1) = f(2) = f(1) - 8 = 100-8 = 92
Let n =2, we get
f(2+1) = f(3) = f(2) - 8 = 92-8 = 84
Let n =3, we get
f(3+1) = f(4) = f(3)-8 = 84 - 8 = 76
Let n =4, we get
f(4+1) = f(5) = f(4)-8 = 76 - 8 = 68
Let n =5, we get
f(5+1) = f(6) = f(5) - 8 = 68-8 = 60
Therefore, the value of f(6) is 60.
