Tom and Becky can paint Jim's fence together in 12 hours. If all people paint at the same rate, how many hours would it take to

Delvig [45]

Answer: 8 hours

Step-by-step explanation:

Let x be the time taken by each person to paint the fence.

Given: Tom and Becky can paint Jim's fence together in 12 hours.

Since all people paint at the same rate, then we have the following equation ;-

$\dfrac{1}{x}+\dfrac{1}{x}=\dfrac{1}{12}\\\\\Rightarrow\ \dfrac{2}{x}=\dfrac{1}{12}\\\\\Rightarrow\ x=24$

Thus, the time taken by each person to paint the fence alone = 24 hours

Now, the time taken by all three paint together:-

$\dfrac{1}{t}=\dfrac{1}{24}+\dfrac{1}{24}+\dfrac{1}{24}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{3}{24}\\\\\Rightarrow\ t=\dfrac{24}{3}=8\text{ hours}$

Hence, it would take 8 hours if all three paint together.

What is 1/2 minus 3/7

Natali [406]

1/14 because you have to have common denominators so you multiply 1/2 by 7/7 and multiply 3/7 by 2/2 so you end up getting 7/14 - 6/14 = 1/14

how do i make the answer appear in pi form. i did 1/6 pi multiply by 1/12 pi and the answer was 0.1370778389 i want it in pi how

andreev551 [17]

Step-by-step explanation:

what you did was you multiplied all numbers (incl. pi as number) :

1/6, pi, 1/12, pi

and that gives 0.137077839. no i or pi attached. just the plain result number.

so, if you need to just calculate the factors of pi, but don't need the fully numeric result, then your problem looks like

1/6 × pi × 1/12 × pi = 1/72 × pi²

so, you have an expression of pi² with a factor of 1/72.

you only need to type in all the factors, not pi itself (that's what you need to add at the end yourself).

James wants to construct a regular hexagon inscribe in a circle with center O and diameter PQ

Brums [2.3K]

Answer:

B. Place the compass at P and draw an arc of length OP across the circle.

Below is the diagram for help.

Step-by-step explanation:

We are given with an already constructed circle of diameter $PQ$ and $OP$ as radius.

To draw a regular hexagon(six-sided), we need to make first cut on the circle of an arc equal to radius of the circle taking any point of the diameter as center

So here, We will consider $P$ as a center and take an arc of length $OP$ and make a cut on the circle.

This would be the first step and James need to repeat the same steps by considering the newly formed cut as center each time.
