Answer:

The volumes of four rectangular prism are 16,54,128,250 cubic feet.

Step-by-step explanation:

Given : One company makes inflatable swimming pools that come in four sizes of rectangular prisms. the length of each pool is twice the width and twice the depth. the depth of the pools are each a whole number from 2 to 5 feet. If the pools are filled all the way to the top.

To find : What is the volume of each pool?

Solution :

Let x be the height of the pool,

The depth of the pools are each a whole number from 2 to 5 feet i.e. 2,3,4 and 5.  

According to question,

The length of each pool is twice the width and twice the depth.

So, width = x , length = 2x and height = x

The equation form to find volume is V=l\times w\times h

V=2x\times x\times x=2x^3

Now,

At x=2

V=2(2)^3

V=2(8)

V=16\text{ ft.}^3

At x=3

V=2(3)^3

V=2(27)

V=54\text{ ft.}^3

At x=4

V=2(4)^3

V=2(64)

V=128\text{ ft.}^3

At x=5

V=2(5)^3

V=2(125)

V=250\text{ ft.}^3

Therefore, The volumes of four rectangular prism are 16,54,128,250 cubic feet.

The equation to find out the volume in this case is V=x*x*2x, or V=2x^3. Use this we can get that the volumes would be 16, 54, 128, and 250.

A shopkeeper sells an article of 400, while he purchases it for 402. Find out loss percent of shop keeper​
Natalija [7]

Answer:

0.5%

Step-by-step explanation:

A shop keeper sells an article for 400

He purchases it for 402.

Therefore, loss = cost price - selling price

402 - 400 = 2

% loss =

loss/cost price x 100%

2/402 x 100%

= 200/402

=0.498

=0.5%

Assume that y varies inversely with x. if y = 16 when x = 1/2, find y when x=32​
MissTica

y varies inversely with x.

Example:

If we multiply x by 2 we need to divide y by 2 too.

So,

If y = 16 and x = 1/2, find y when x = 32

Lets see, from 1/2 to 32 e need to multiply 1/2 by 64, right? So let's divide 16 by 64.

16/64 = 8/32 = 4/16 = 2/8 = 1/4

So we can say that:

If y = 16 when x = 1/2, y = 1/4 when x = 32.

Scorpion4ik [409]

Answer: 204 students

Step-by-step explanation: To find  out the greatest number of students that can fit at the 17 tables in the school cafeteria, we simply need to multiply the number of students that can fit at each table by the number of tables.

12 students can fit at 1 table and there are 17 tables.

So we have (12)(17) which is 204.

So the greatest number of students that can be seated din the cafeteria is 204 students.

aev [14]

Answer:

The number of men was 80

The number of women was 70

Step-by-step explanation:

The question in English is

Having organized a bingo has raised $1900. For the entrance of men $15 and women $10 and an attendance of 150 people has been reported. Determine the number of men and the number of women who participated in the bingo.

Let

x----> the number of men

y----> the number of women

we know that

x+y=150

x=150-y -----> equation A

15x+10y=1,900 -----> equation B

substitute equation A in equation B and solve for y

15(150-y)+10y=1,900

2,250-15y+10y=1,900

15y-10y=2,250-1,900

5y=350

y=70

Find the value of x

x=150-70=80

therefore

The number of men was 80

The number of women was 70
