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>

A direct variation exist between x and y. When x=4, y=3. What is the value of y when x=10
scoray [572]

Answer:

y = 7.5

Step-by-step explanation:

Given

Direct variation implies that:

y = kx

Where k is the constant of variation.

x=4; y=3

Required

Find y when x = 10

y = kx

Make k the subject

k = \frac{y}{x}

For: x=4; y=3

k = \frac{3}{4}

For: x = 10

k = \frac{y}{x} becomes

k = \frac{y}{10}

Substitute k = \frac{3}{4}

\frac{3}{4} = \frac{y}{10}

Make y the subject

y = \frac{3}{4} * 10

y = \frac{3* 10}{4}

y = \frac{30}{4}

y = 7.5

It takes the hot water faucet 4 times as long to fill a bathtub as it does the cold water faucet. Left on together, the cold and
Debora [2.8K]

If it takes the cold water faucet x minutes to fill 1 tub, then its flow rate is (1 tub)/(x min).

The hot water faucet takes 4 times as long, so its flow rate is (1 tub)/(4x min).

Together, the total flow rate is (1 tub)/(3 min), so we have

\dfrac1x+\dfrac1{4x}=\dfrac13

\implies\dfrac5{4x}=\dfrac13

\implies15=4x

\implies x=\dfrac{15}4\,\text{min}=3\,\text{min}\,45\,\text{sec}

Anybody have the answer?
mars1129 [50]
Hello!

Here we have sin=opp/hyp so the sin of 45deg= 7/b so we have

Sqrt(2)/2 = 7/b so b= 7/sqrt(2)/2= 14/sqrt(2)= 14*sqrt(2)/2= 7*sqrt(2) so the final simplified answer for the value of b= 7*sqrt(2)

Any questions please ask. Thank you kindly.
