Total minute(one year) = 15 X 365 no of pages read in one year = 12 x 200 = 1200

number of page read in one minute = no of pages read in one year/total minute(one year) = 2400/5475= .4383

ie 1 minute - .4383 page

ie 60 sec - .4383 page

time for 1 page 60/.4383 = 136.89

Part 2

Time needed to read a page 30 sec less

ie 136.89 -30 = 106.89.

so number of pages read in 1 sec = 1/106.89

number of pages read in 1 min = 1/106.89 * 60

number of pages read in a day = 1/106.89 * 60 * 20

number of pages read in a year = 1/106.89 * 60 * 20 * 365 = 4097.67 ( ie 1/106.89 * 7300)

number of books = number of pages read in a year/200 = 20.49

Help please fast the format is Y-____=_____(x - ____) and i need the actual answer
mojhsa [17]

Answer:

  • y -195 = 15(x -9)
  • $60

Step-by-step explanation:

The form of the equation you are given is called "point-slope" form. The "slope" in this case is the per-hour fee. The point is (9 h, $195). Point-slope form generally looks like this:

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

Here, you have m=15, (h, k) = (9, 195), so the equation looks like ...

  y -195 = 15(x -9)

__

The "one-time fee" is the cost when hours are zero.

  y -195 = 15(0 -9)

  y = 195 -9(15) = 60 . . . . add 195 to both sides, and evaluate

The one-time fee is $60.

Solve each inequality. <br> 1. 5x + 2 &lt;17
butalik [34]

Answer:

x<3

Step-by-step explanation:

5x+2<17

Subtract 2 from both sides.

5x<17−2

Subtract 2 from 17 to get 15.

5x<15

Divide both sides by 5. Since 5 is positive, the inequality direction remains the same.

x=15/5

Divide 15 by 5 to get 3.

x<3

Find the midpoint of CD. C= (7,-4) and D= (-8,-5)
ANTONII [103]

Answer:

( -\frac{1}{2},-\frac{9}{2})

Step-by-step explanation:

The equation of a midpoint is as follows:

(\frac{x_{1} +x_{2}}{2} ,\frac{y_{1} +y_{2}}{2})

The x-coordinate:

x1 = 7, x2 = -8

7+(-8) = -1

Divide by 2 to get the x-midpoint

-1/2

The y-coordinate

y1 = -4, y2 = -5

-4 + (-5) = -9

Divide by 2 to get the y-midpoint

-9/2

You get:

( -\frac{1}{2},-\frac{9}{2})
