Kyle gave 2/7 of his money to his wife and spent 3/5 of the remainder. If he had $300 left, how much money did he have at first?

weqwewe [10]

Answer:

Kyle gave 2/7th of his money to his wife and spent 3/5 of the remainder. If he had $300 left, the money had by Kyle at first is $1050

Solution:

Step 1:

Consider “x” as the money which Kyle had initially.

From question, Kyle gave 2/7th of his money to his wife. So the remaining money left with Kyle is given as,

$= 1 - \frac{2}{7}$

$= \frac{7 - 2}{7} = \frac{5}{7}$ ----- eqn 1

Now the remaining money left with Kyle is 5/7th.Given that Kyle spent 3/5 of the remaining money.

Now the remaining money left with Kyle is given as

$= 1 - \frac{3}{5} = \frac{5 - 3}{5} = \frac{2}{5}$

Now kyle is left with $300, which is 2/5th of the initial money x .

We get equation as

$\frac{2}{5} x=300$

2x = 1500

x = 750

Now Kyle is left with 750$ which is 5/7th of the initial amount x.( by using eqn 1)

We get equation as

$\frac{5}{7} x = 750$

5x = 5250

x = 1050

So the amount had by Kyle at first is $1050

Find the work (in ft-lb) required to pump all the water out of a cylinder that has a circular base of radius 7 ft and height 200

Virty [35]

Answer:

work done is equal to 384279168 lb-ft

Step-by-step explanation:

The cylinder has a circular base of 7 ft.

The height of the cylinder is 200 ft

The weight density of water in the cylinder is 62.4 lb/ft^3

First, we find the volume of the water in the cylinder by finding the volume of this cylinder occupied by the water.

The volume of a cylinder is given as $\pi r^{2} h$

where, r is the radius,

and h is the height of the cylinder.

the volume of the cylinder = $3.142* 7^{2}*200$ = 30791.6 ft^3

Since the weight density of water is 62.4 lb/ft^3, then, the weight of the water within the cylinder will be...

weight of water = 62.4 x 30791.6 = 1921395.84 lb

We know that the whole weight of the water will have to be pumped out over the height of cylindrical container. Also, we know that the work that will be done in moving this weight of water over this height will be the product of the weight of water, and the height over which it is pumped. Therefore...

The work done in pumping the water out of the container will be

==> (weight of water) x (height of cylinder) = 1921395.84 x 200

==> work done is equal to 384279168 lb-ft

I need help! I already asked this but both the answers came out as wrong. Help please?

I believe the area of that polygon is 473 square feet because to find the area of the odd corner you have to look at the differences between the different side lengths, so 2*5=10 and then you have to divide 10 by 2 because only half of that corner is there.
