To solve this problem you must apply the proccedure shown below:
1. First, you must multiply $8 by the hours given in the exercise:

2. Now, multiply the result obtained above by 4, to calculate her monthly income:
3. If 22% of her paycheck goes to taxes, you have:
![(800dollars)-[(800dollars)(0.22)]=624dollars](https://tex.z-dn.net/?f=%28800dollars%29-%5B%28800dollars%29%280.22%29%5D%3D624dollars)
Therefore, the answer is: $624
The answer is C that is X=27

Answer:
Step-by-step explanation:
If Daniel does 1/9 of the job in one hour
let x = Paul's rate
Paul does 1/x of the job in one hour
They both do the job in 4.95hrs
(1/9)(4.95) + (1/x)(4.95) = job completion
multiply both sides by 9x
(9x)(1/9)(4.95) + (9x)(1/x)(4.95) = 9x(1)
4.95x + 9*4.95 = 9x
4.95x + 44.55 = 9x
9x - 4.95x = 44.55
4.05x = 44.55
x = 44.55/4.05
x = 11 hours i.e time it takes for Paul to pick the 40 bushels alone
Answer:
Note: The expression "h =300- pi r /pi r" would equate to 299, as written. I find h = (300 - π
)/πr to be the equation for height.
Step-by-step explanation:
The total surface area of a sylinder is 2πr(h+r) where h is the height and r is the radius. That consists of top and bottom disks, each with an area of π
, for a total of 2π
. The side is a continous sheet that has an area of 2πrh, where h is the height. 2πr is the circumference of the can, so the surface area of the side is 2πrh.
The total surace area of a closed cylinder is therefore 2π
+ 2πrh.
2π
+ 2πrh = 600
π
+ πrh = 300
πrh = 300 - π
h = (300 - π
)/πr
