If a worker can do his job in 5 hours, and a student can do the same job in 8 hours, what part of the work is left to finish aft

Aleks [24]

Answer:

Part of work left to finish after two work hours is 7/20

Step-by-step explanation:

Firstly, we need to calculate their joint work rate

That will be;

1/(1/5 + 1/8) = 1/(13/40) = 40/13

This means that they will complete the task in 40/13 hours

1 whole part takes 40/13

x part will take 2 hours

x * 40/13 = 2

40x = 26

x = 26/40

So the part that will be completed in two hours is 26/40

This means that the part left to complete will be:

1 - 26/40 = 14/40 = 7/20

Which choice is equivalent to the quotient below shown here when x>0?

qwelly [4]

Answer:

Choice B is correct

Step-by-step explanation:

The given radical division can be expressed in the following form;

$\frac{\sqrt{16x^{3} } }{\sqrt{8x} }$

Using the properties of radical division, the expression can be expressed in the following form;

$\sqrt{\frac{16x^{3} }{8x} }=\sqrt{2x^{2} }$

Simplifying further yields;

$\sqrt{2x^{2} }=\sqrt{2}*\sqrt{x^{2} }=x\sqrt{2}$

Choice B is thus the correct alternative

A sports magazine prints 12 issues per year, and a technology magazine prints 10 issues per year. The total number of pages in a

Evgesh-ka [11]

Answer:

$s=t-18...(1)$

$12*s=10*t+32...(2)$

Step-by-step explanation:

Let s be the number of pages in each issue of the sports magazine, and t be the number of pages in each issue of the technology magazine.

We have been given that Each issue of the sports magazine has 18 fewer pages than each issue of the technology magazine. We can represent this information in an equation as:

$s=t-18...(1)$

We are also given that sports magazine prints 12 issues per year, so the total number of pages in all the issues of sports magazine will be 12*s.

We are given that a technology magazine prints 10 issues per year, so the total number of pages in all the issues of technology magazine will be 10*s.

Further, the total number of pages in all the issues of the sports magazine for one year is 32 more than the total number of pages in all the issues of the technology magazine for one year.

We can represent this information in an equation as:

$12*s=10*t+32...(2)$

Therefore, our desired system of equations will be:

$s=t-18...(1)$

$12*s=10*t+32...(2)$
