Answer:
First option is the correct answer.
Step-by-step explanation:
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
In the year 2008 and 2009, the company had profit 2.5 thousand dollars and 1.75 thousand dollars consecutively
In the year 2010 and 2011, the company experienced a loss of 3.3 thousand dollars and 1.4 thousand dollars.
Total profit is 2.5 + 1.75 = 4.55 thousand dollars
Total loss = 3.3 + 1.4 = 4.7 thousand dollars
Total loss is bigger than the total profit so the company needs to make profit in 2012 to break even = 4.7 - 4.55 = 0.37 thousand dollars (this is the least profit the company needs to make)
Since in this problem, we are dealing with a balloon we can now say that the container or the shape we are dealing with is a sphere. The volume of a sphere is
hence the volume is directly proportional to the radius. The volume increase by a factor of
