18 Electricians can complete the wiring in 28 days. We are to find how days will 28 electricians take for the same task.
Note that, if the number of electricians are increased, the number of days will be less to complete the same job. So we can conclude that there is an inverse relation between the Electricians and the number of days.
Let 28 electricians take x days to complete the same task. In an inverse relation, the product of two quantities is always equal to the constant of proportionality.
So, we can write:
18(35) = Constant of proportionality
and
28(x) = Constant of proportionality
From both these equation, we can write:
18(35) = 28(x)
⇒ x = 22.5
So, this means 28 electricians will do the same task in 22.5 days
Answer:
➩
Step-by-step explanation:
➨ We can also solve by completing both squares, however. Since we can pull out the square root.
➩ Define of Absolute Value/Square Root
➩
Thus, our new equation is ➩
To solve an absolute-value equation, let there be two conditions.
➨ Where x ≥ 0
Move x to another side
➨ Where x < 0
The answer is that there are no solutions to the equations. They are parallel to each other and never cross. They can also be called inconsistent
Answer:
decagon is 36° 20-gon is 18°
Step-by-step explanation:
divide de number of sides by 360
N/360
10/360= 36
50 is the answer to this question
