29. A carpenter worked for 4 days to finish a repair job. She charged $825 for 15 hours plus $278 for materials. What is the carpenter's rate per hour?
Let’s start solving:
=> 825 dollars + 278 dollars = 1 103 dollars is the total payment a carpenter have received
=> 15 hours is the total hours he worked
=> 1 103 / 15 = 73.5 dollars per hour. This is already including the material or equipment fee.
Step-by-step explanation:
Percentage Calculator: What is the percentage increase/decrease from 4000 to 5000? = 25.
We will determine the surface area as follows:
So, the total surface area is 150 cm^2.
it's a right triangle so you use Pythagoras' theorem.
√28²-14²=
√784 - 196 =
√588
24.24 units (rounded 24.25)
your answer is 24.25 units
