Answer:
The answer is (π/4)*r
Step-by-step explanation:
Formula length of arc when the angle given is in radian as the case given
s = r*θ
s = arc length (in radians)
r = radius
θ = central angle in radians
But when the angle given is in degrees the length is expressed as
s= 2πr*(θ/360)
Let's represent the number of hours with the variable 'h' (or whatever letter you want it to be):
265 + 48h = 553
Substract both sides by 265:
48h = 288
Divide:
h = 6
6 hours of labor was spent
Answer:
There is money left over. They have 48.98 dollars left.
Step-by-step explanation:
Men costumes in total cost $102.68 and women costumes in total cost $248.34. There budget it $400 so we add both the men and women costumes together which is $351.02 which means that they do have left over money. To find the left over money, we have to subtract $400 from $351.02 which is equal to $48.98.
1.) 75 x .62 = 46.5 I multiplied by .62 because the kph to mph ratio is 1:.62
2.) 20 x 1.6 = 32 I multiplied by 1.6 because that's how many km are in a mile.
