Answer: The most cost effective company is Painting USA as it is cheaper comparatively.

Step-by-step explanation:

Since we have given that

Number of hours needed to paint Paul's house = 25 hours

Initial charges of Painting USA to evaluate the house = $75.00

Cost per hour of labor = $25.00

Total cost of Painting USA would be given by

75+25\times 25\\\\=75+625\\\\=\$700

And Upscale Home painting does not charge to evaluate the house.

Cost per hour by Upscale Home painting = $40.00

Total cost of Upscale painting would be

25\times 40=\$1000

Hence, the most cost effective company is Painting USA as it is cheaper comparatively.

Answer:

Step-by-step explanation:

Painting USA

25*25=625 + 75= 700

Upscale Home Painting

40 * 25 = 1,000

It would be better to go with Painting USA because it is cheaper, while Upscale Home Painting is more expensive.

If the sum of four consecutive numbers is 854, what is the third one?
lukranit [14]

Answer:

214

Step-by-step explanation:

The set up would be x + (x + 1) + (x + 2) + (x + 3) = 854, naturally as the numbers are consecutive. Solving for x:

x + (x + 1) + (x + 2) + (x + 3) = 854,

x + x + 1 + x + 2 + x + 3 = 854,

4x + 1 + 2 + 3 = 854,

4x + 6 = 854,

4x = 854 - 6 = 848,

x = 848/4 = 212

The third number then should be 212 + 2 = 214

The area of a circle is 77.28m2.<br> Find the length of the diameter rounded to 1 DP.
allochka39001 [22]

Answer:diameter=9.92m

Step-by-step explanation:

Area=77.28

π=3.14

Area=π x (d/2)^2

77.28=3.14 x (d/2)^2

Divide both sides by 3.14

77.28/3.14=(3.14x(d/2)^2)/3.14

24.6=(d/2)^2

Take them square root of both sides we get

d/2=√(24.6)

d/2=4.96

d=4.96 x 2

d=9.92

Find the domain of the rational expression: x-4/2x-6
marin [14]

Answer:

All real numbers except 3

Step-by-step explanation:

Given

\frac{x - 4}{2x - 6}

Required

Determine the domain

We start by writing the following inequality

2x - 6 \neq  0

Add 6 to both sides

2x -6 + 6 \neq = 0 + 6

2x \neq  6

Divide both sides by 2

\frac{2x}{2}\neq  \frac{6}{2}

x \neq  \frac{6}{2}

x \neq = 3

<em>As such, the domain of x is all real numbers except 3</em>
