Answer:
288
Step-by-step explanation:
First, find how much of the desk each person can finish in 1 hour. Paul can finish 1/12 because he finishes the whole thing in 12 hours and Shawn can finish 1/8 because he finishes the whole thing in 8 hours.
Then find a common denominator and add those together to find how much they could do together in 1 hour.
2/24 + 3/24 = 5/24 So they can finish 5/24 of the desk in 1 hour if they work together.
So to finish 24/24 of the desk, they'll need to do 4 hours (20/24 of the desk) and 48 minutes (4/24 of the desk)
It asked for the number of minutes, so multiply 4 by 60 and add 48 to find the total number of minutes. 4*60 = 240 and 240 + 48 = 288
So it will take them 288 minutes to build the desk together.
Answer:
-128
Step-by-step explanation:
y = -200-6(X) , x = -12
y = -200 - 6(-12)
y = -200 - (-72) (6x-12=-72) - with a - equals a +
y = -200 + 72
y = -128 ( you minus 200 and 72 and leave the minus sign)
Answer:
(Approximation to the nearest thousandth)
Step-by-step explanation:
The area of a cylinder can be determined by the formula:
(We know that the radius, r, is 2m, and the height, h, is 5m, so we can substitute them into the formula to calculate the volume of this cylindrical tank)
(Simplify)
