Of the 120 apartments in a building, 75 have been scheduled to receive new carpet. What fraction of the apartments have not been scheduled to receive new carpet?

1/4
3/8
5/8
3/4

Answers

Answer:

3/8

Step-by-step explanation:

Well, let's start out by figuring out how many apartments have not been scheduled to receive new carpet. We know that 75 have been scheduled and that there are 120 total apartments, so the number of apartments that have not been scheduled is 120 - 75 or 45.

Now, we need to find the fraction of apartments that have not been scheduled to receive new carpet. To do this, we divide the number of apartments that have not been scheduled to receive new carpet by the total number of apartments:

[tex]\frac{45}{120}[/tex]

We can divide both sides by a common factor of 15 to find the simplified fraction and determine our answer.

[tex]\frac{45}{120} /\frac{15}{15} =\frac{3}{8}[/tex]

So, 3/8 of the apartments have not been scheduled to receive new carpet.

Answer:

Step-by-step explanation:

We must prove that triangles ABC and EDC are congruent.

Since BD bisects AE, then AC is congruent with CE.

Since AE bisects BD, then BC is congruent with CD

Angle C is 90° in the triangle EDC and is also 90° in triangle BCA because they are vertical angles.

Being two sides and the included angle congruent, then both triangles are similar by the SAS theorem.

Answer:

7.22 x 10^5

Step-by-step explanation:

Remember that the decimal is always to the right of the ones place.

1. Move it one place to the left and multiply by 10 to compensate.

2. Move it two places to left and multiply by 10^2.

3. Move the decimal point three times and multiply 10^3 to compensate, and the pattern continues until you reach the very last digit, the 7.

4. Numbers after the 7 that are not zeros will be after the decimal point.

so, 7.22 x 10^5

Find the perimeter.simplify your answer.

Answers

The perimeter of a shape is the sum of its side lengths.

The perimeter of the shape is 24z - 18

Represent the length with l and the width with w.

The dimensions are given as:

[tex]l = 10z[/tex]

[tex]w = 2z - 9[/tex]

So, we have:

[tex]P =2 \times (l + w)[/tex] --- the formula of perimeter

The above equation becomes

[tex]P = 2 \times (10z + 2z - 9)[/tex]

Evaluate like terms

[tex]P = 2 \times (12z - 9)[/tex]

Open brackets

[tex]P = 24z - 18[/tex]

Hence, the perimeter of the shape is 24z - 18

Suppose that the functions r and s are defined for all real numbers x as follows.
r(x)=x+3
s(x) = 2x
Write the expressions for (r-s) (x) and (-s) (x) and evaluate (r+s) (-1).

Answers

Step-by-step explanation:

as explained in the other question : when applying an arithmetic operation on functions, you are applying it on the functional expressions.

(r*s)(x) = (x+3)*(2x²) = 2x³ + 6x²

(r-s)(x) = (x+3) - (2x²) = -2x² + x + 3

(r+s)(-1) = (-1 + 3) + (2×(-1)²) = 2 + 2×1 = 4

A line passing through the point(-10,-5) and has a slope of -1/2

Answers

y = -1/2x - 10

ex : -10 is x, -5 is y, -1/2 is slope

y = mx + b, m is slope, solving for b (y-intercept)

-5 = -1/2(-10)+b
-5 = 5 + b

try to get b by itself, so minus the positive 5

-5-5 = b, so -10 = b

which leads to y = -1/2x - 10

A pool with a square bottom is to have a volume of 2000 cubic feet. The owners plan to use a fancy tile to complete the pool. The sides of the pool will cost $80 per square foot and the bottom of the pool will cost $40 per square foot. Find the pool dimensions that will minimize the cost of construction.

Answers

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

2w + 8 + w = 48

3w = 40

w = 40/3

l = 2*40/3 + 8
