Considering the given conditions in the question, the dimensions that will minimize the cost of construction of the pool are:

base length = 10 feet

base width = 10 feet

pool depth = 20 feet

Volume of a material implies the maximum amount of substance that it can contain.

From the given question, it is expected that the pool would have the shape of a cuboid, thus its volume can be determined by:

volume of the pool = length x width x height

                                = base area x height

Thus, given that the volume of the pool is 2000 cubic feet, then;

2000 = base area x height

i. Let the dimensions of the square base be 10 feet, and its height 20 feet, so that;

volume = 10 x 10 x 20

            = 2000 cubic feet

The cost of constructing the pool of the assumed dimensions would be:

Total area of its sides = 4 x 200

                                    = 800 square feet

The cost of tiling the sides of the pool = $80 x 800

                                         = $ 6400.0

Area of the base of the pool = 10 x 10

                                            = 100 square feet

The cost of tiling the base of the pool = $40 x 100

                                         = $4000

Total cost = $6400 + $4000

                 = $10400

Total cost of constructing the pool with the assumed dimensions is $10400.

ii. Let the dimensions of the square base be 20 feet, and its height 5 feet, so that;

volume = 20 x 20 x 5

            = 2000 cubic feet

The cost of constructing the pool of the assumed dimensions would be:

Total area of its sides = 4 x 100

                                    = 400 square feet

The cost of tiling the sides of the pool = $80 x 400

                                         = $ 32000

Area of the base of the pool = 20 x 20

                                            = 400 square feet

The cost of tiling the base of the pool = $40 x 400

                                         = $16000

Total cost = $16000 + $32000

                 = $48000

Total cost of constructing the pool with the assumed dimensions is $48000.

Therefore, the dimensions that will minimize the cost of construction of the pool are:

base length = 10 feet

base width = 10 feet

pool depth = 20 feet

90 degrees on each angle.

Answer:

183in^2

Step-by-step explanation:

Given that the length is 15 in and the width is 26 in we can figure out the area of a full rectangle.

15x26=390in

We now want to figure out the small rectangle on the bottom of the image.

The area of a triangle is A=hb/2

A=6x15/2=45

In the image, you can see that the rectangle is incomplete and missing part of it. It's missing a triangle so in order to complete the rectangle you multiply 45x2.

45x2=90

Finally, we can solve for the remaining triangle.

A=9x26/2=117

Add up the triangles and subtract the sum from the area of the rectangle to get the shaded area.

390-(90+117)=183in^2

Step-by-step explanation:

On adding 60 to 325 and then subtracting 40 the answer will be 345.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given numbers 60, 325, and 40. The expression will be formed as below:-

E = 60 + 325 - 40
E = 385 - 40

E = 345

Therefore, on adding 60 to 325 and then subtracting 40 the answer will be 345.

Answer:

Write an equation the represents the words.

6x - 7 = 4x + 9

To solve for x (the number), isolate it from the other variables.

Subtract 9 from both sides.

6x - 7 - 9 = 4x

Combine like terms.

6x - 16 = 4x

Subtract 6x from both sides.

-16 = 4x - 6x

Combine like terms.

-16 = -2x

Divide both sides by -2.

-16/-2 = x

x = 8

The number is 8.

Answer:

The number is 8.

Step-by-step explanation:

Hello there!

We're given an unknown number, let's call this number n

We know that 7 less than 6 times n is equal to 9 more than 4 times n

Let's break that statement down, starting with "7 less than 6 times n"

6 times n should be 6n, since 6 * n = 6n

"7 less" means subtraction.

So "7 less than 6n" should be 6n-7

Now with "9 more than 4 times n"

4 times n should be 4n, as 4 * n = 4n

"9 more" means addition

So "9 more than 4n" should be 4n+9

The statement says that 6n-7 is equal to 4n + 9, and so when we write it as an equation:

6n - 7 = 4n + 9

Now we can solve the equation

Subtract 4n from both sides

2n - 7 = 9

Add 7 to both sides

2n = 16

Divide both sides by n

n=8

The number is 8

PS. we can substitute 8 back into the equation as n to see if it works:

6(8)-7=4(8)+9

Multiply

48-7=32+9

41= 32 + 9

41=41

It works :))

Answer:

y = 3/4x - 5/4

Step-by-step explanation:

6x=8y+10

Well you must first get your equation set up into the form called "Slope intercept."

6x=8y+10

Add 8y on both of your sides because your y is suppose to be alone.

8y + 6x = 10

Subtract 6x on both sides since it is in fact the opposite of addition.

8y = 6x + 10

Now, you will divide by 8 on both sides. When doing this your y will be alone.

y= 6/8x + 10/8

Note: You can leave it like this but you want to probably simplify.

y = 3/4x + 5/2

      or

y = 3/4x - 5/4

Answer:

2.5

Step-by-step explanation:

"Four different positive integers have a mean (average) of 100"

The total of the 4 numbers is then 4* 100 = 400

"the positive difference between the smallest and largest of these integers is as large as possible"

to get the greatest difference the first 3 numbers must be

1, 2 and 3 which totals 6

the 4th number is then 400 - 6 = 394

the four numbers are 1, 2, 3 and 394

The greatest difference is between 1 and 394

"the average of the other two integers"

(2 + 3)/2 = 2.5

The average of the other two integers is 1.5.

An integer is an whole number. An example of an integer is 20.

If the mean of the four integers is 100. It means that the sum of the integers must be 400. If the integers are 0,1,2, 397. The largest number is 397 and the smallest number is 0. The average of the other two integers is (1 + 2 ) / 2 = 1.5
