The new hourly rate is $6.15. To find this, you have to set up the rate and percent as x/6=2.5/100. You cross multiply. x times 100 equals 100x. 6 times 2.5 equals 15. It would be written as 100x/100=15/100. You divide by 100 to leave x by itself. 15 divided by 100 equals 0.15. So, x equals $0.15 cents. You add 6 and 0.15. Together, they add up to $6.15. Hoped this helps!
Step-by-step explanation:
You forgot to include the formula, but it has to be either a sine wave or cosine wave:
h = A sin(ωt + φ) + B
The coefficient A is called the amplitude. The diameter of the ferris wheel is double the amplitude.
d = 2A
Answer:
Step-by-step explanation:
d = 200 miles
B rate = x
A Rate = x + 20
Each has traveled two hours
The total distance each travels after two hours is 200 miles (they pass each other).
d = r * t
2*x + 2*(x + 20) = 200 Remove the brackets
2x + 2x + 40 = 200 Combine like terms
4x + 40 = 200 Subtract 40 from each side
4x = 200 - 40
4x = 160 Divide by 4
x = 160/4
x = 40
There B's rate is 40 miles / hour
A's rate is 40 + 20 = 60 miles / hour
