Sati [7]

Given :-

  • 12 workers can do a piece of work in 20 days .

To Find :-

  • How many workers should be added to complete the work in 16 days ?

Solution :-

According to the question ,

→ In 20days 12 workers can do a piece of work.

→ In 1day 12*20 workers can do that work

( Less days , more workers )

→ In 16 days 12*20/16 = 15 workers can do the work.

So 15 -12 = 3 workers should be added to complete the work.

<u>Hence</u><u> the</u><u> required</u><u> answer</u><u> is</u><u> </u><u>3 </u><u>.</u>

<em>I </em><em>hope</em><em> this</em><em> helps</em><em>.</em>

Substitution. (6 points) <br> 3x + 2y = 11 <br> y = 5x - 1<br><br> {show work}
nexus9112 [7]
3x+2y=11
y=5x-1

Substitute the y in the first equation:
3x+2(5x-1)=11
y=5x-1

3x+10x-2=11
y=5x-1

13x=13
y=5x-1

Now substitute the x to find the y:
x=1
y=5-1=4

A cylindrical storage container has a radius of 8 inches and a height of 18 inches. What is the volume of the storage container?
antoniya [11.8K]
Use the formula for the volume of a cylinder.

V = area of the base * height

area of the base = π (radius)^2

V = π(radius)^2 * height = π(8 in)^2 (18in) = 1,152π in^3

If you use π≈3.14, you get

V = 3,617.28 in^3
