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:
x = 35
Step-by-step explanation:
we know that all triangles add up to 180
you first need to make an expression in which the angles equal 180
105 + 140 + x = 180
145 + x = 180
subtract 145 from both sides
x = 35
Answer:
4250 children.
Step-by-step explanation:
72 - 38 = 34
34 degrees = 578 people
/34 /34
1 degree = 17 people
72 + 38 = 110
360 - 110 = 250
17 * 250 = 4250 children.
