According to a survey conducted by the Texas Free Press, 125 out of 500 people do not have internet access at their homes. What percent of the people surveyed do have internet access at their homes?

Answers

75%
500-125 is 375
375/500 gives 3/4 which is .75
move the decimal over to the right twice to get 75%

125 do not                    

375 have

500 is the total

500-125 =375

375/500

500 divided by 375 = 0.75

log(x+1)−log(x−8)=log(10)

How do i solve this?

Answers

Answer:

  x = 9

Step-by-step explanation:

The applicable rule of logarithms is ...

  log(a) -log(b) = log(a/b)

__

Use the rules of logarithms to simplify the left side to a single log, then take the antilogs and solve the resulting equation.

  log(x+1) -log(x-8) = log(10)

  log((x+1)/(x-8)) = log(10)

  (x +1)/(x -8) = 10 . . . . . . . take antilogs

  x +1 = 10(x -8) . . . . multiply by x-8

  81 = 9x . . . . . . . add 81-x, simplify

  9 = x . . . . . . . . . divide by 9

What is the intermediate step in the form (x + a)? = b as a result of completing the
square for the following equation?
x2 + 18x + 57 = 12

Answers

Answer:

(x + 9)² = 36

Step-by-step explanation:

Given

x² + 18x + 57 = 12 ( subtract 57 from both sides )

x² + 18x = - 45

To complete the square

add ( half the coefficient of the x- term)² to both sides

x² + 2(9)x + 81 = - 45 + 81

(x + 9)² = 36

Ryan wrote a total of 8 pages over 2 hours. How many hours will Ryan have to spend writing

Answers

So it says he writes 8 pages in 2 hours. Which would mean he takes an hour to write 4 pages. You divide 48 pages by 4 hours and you get 12.

The image point of A after a translation right 2 units and down 1 unit is the point B (10,−1). Determine the coordinates of the pre-image point A.

Answers

Answer:

pre image point A (8,0)

Step-by-step explanation:

I guess thats the answer

A = (x, y)

After a translation right 2 units and down 1 unit is the point B (10, -1)

A = (x + 2, y - 1)

B = (10, -1)

A = B

x + 2, y - 1 = 10, -1

x, y = 10 - 2, -1 + 1

x, y = 8, 0

(x, y) = (8, 0)

The coordinates of pre-image point A is (8, 0)

As per the quadratic equation, the given equation can be modified into    (x - 2)² = 1. The value of x is 3, 1.

What is a quadratic equation?

A quadratic equation is an equation where the variable has the highest degree of 2. A quadratic equation might have more than one variable. However, the highest degree of any variable must be 2.

Given equation: x² - 4x + 3 = 0

⇒ x² - 4x + 3 + 1 = 1          (By adding 1 on either side)

⇒ x² - 4x + 4 = 1

⇒ x² - 2 × x × 2 + 2² = 1

⇒ (x - 2)² = 1

⇒ x - 2 = ±1

⇒ x = 3, 1

Answers

Answer:

a) 36

b) 8.5

c) 5/2

d) 6

e) 9

f) 8

Step-by-step explanation:

a) [tex]x \div 3 =12[/tex]

Multiply both sides by 3

[tex]x \div 3 =12\\3*(x \div 3) = 12*3\\x=36[/tex]

b) [tex]2x+3=20[/tex]

Subtracting 3 from both sides

[tex]2x+3-3=20-3\\2x=20-3\\2x=17\\x=\frac{17}{2}\\x=8.5[/tex]

c) [tex]\frac{4}{3}x=\frac{10}{3}[/tex]

Multiply both sides by 3/4

[tex]\frac{4}{3}x*\frac{3}{4} =\frac{10}{3} *\frac{3}{4}\\x=\frac{5}{2}[/tex]

d) [tex]-4x=-24[/tex]

Divide both sides by -4

[tex]-4x=-24\\\frac{-4x}{-4}=\frac{-24}{-4}\\x=6[/tex]

e) [tex]2(x-4)=10[/tex]

Divide both sides by 2

[tex]2(x-4)=10\\\frac{2(x-4)}{2}=\frac{10}{2}\\x-4=5\\Adding \ 4 \ on \ both \ sides\\x-4+4=5+4\\x=9[/tex]

f) [tex]-0.5x+1.1=-2.9[/tex]

Subtracting 1.1 on both sides

[tex]-0.5x+1.1-1.1=-2.9-1.1\\-0.5x=-4\\Divide \ both \ sides \ by \ -0.5\\\frac{-0.5x}{-0.5}=\frac{-4}{-0.5}\\x=8[/tex]

Answers

9514 1404 393

Answer:

  D. $40 with 25% discount

Step-by-step explanation:

All of the options have 8% sales tax, so that is not important to choosing the best deal.

The store with the lowest price after discount is D (local shoe store #2), as the discount brings the price down to $30 before tax.

The price at store C (local shoe store #1) will be 15% less than $38.00, so about $5.70 less. That is not as low a price as at store D.

The best buy is had at store D.

__

In the spreadsheet, we have multiplied the base price by (1+discount) then added shipping. That total is multiplied by (1+tax rate).

okay so for the #1 it says that it take 1/2 (half) a day to paint 1/4 of your bedroom and we want to know how many days it would take to paint all of the bedroom, so 4/4 of the bedroom.
We can say that
1/2(number of day) = 1/4(how much you painted)
to paint all of your room you would have to have painted 4/4 of your room
to get to 4/4 i multiplied 1/4 by 4
you do the same thing to 1/2 so 1/2•4=2
So it would take 2 days to paint all (4/4) of your bed room

I dont if im clear but just think about it
If you take half a day to pain 1/4 of your room, in one day you would’ve painted 2/4 of your room, so in one day you paint 2/4 of your room. And in 2 days you paint 4/4 of your room

A parallelogram is a basic quadrilateral with two sets of parallel sides.

The confronting or opposing sides and the opposing angles of a parallelogram are of equal length.

A quadrilateral is a quadrilateral because it has four sides not because it is quadrilateral so it has four sides.

For example, 4 sides are equal so the square is not due to the square all lines will same.
