The carpenter makes 1/4 of the job per hour.
The assistant makes 1/6 of the job per hour.
When they work together, they make 1/4 + 1/6 = 6/24 + 4/24 = 10/24 = 5/12 of the job each hour.
Thus, it will take 12/5 = 2 2/5 hours = 2 hours and 24 minuets for them to finish the job working together.
Here is the equation to solve the problem above:
f(x) = (7-x)^3
y = (7-x)^3
switch y and x
x = (7 - y)^3
third root of x = 7 - y
-y = 3rootx - 7
so:<span><span>f′(x)=3^<span>√x</span>−7</span></span>
Answer:
Step-by-step explanation:
This linear graph will be shifted downward by 2 1/2 units: first, from y = 1/2 to the x-axis, and next, from the x-axis by 2 more units, for a total shift of 2 1/2 units.
Answer:
1 is a competition, 2 is protection, 5 is division, and 8 is solution.
Step-by-step explanation:
hope these are all correct and you ace this!
If you buy ' N ' of each item, then you'll pay 3.99N for brushes,
21.79N for cans of paint, and 6.89N for rollers.
The question assures us that you bought the same number of
each item. So your total bill at the hardware store checkout is
3.99N + 21.79N + 6.89N
= N (3.99 + 21.79 + 6.89)
= 32.67 N .
