To find the percent, divide 9 by 27 to get a decimal, then multiply the decimal by 100 to get the percent:

9 / 27 = 0.333

0.333 x 100 = 33.3%

m = the number of miles driven

C(m) = 0.10m + 41   (Speedy charges a flat rate of $41 plus an additional fee of $0.10 per mile(m) driven)

T(m) = 0.25m  (Tom's Car Rentals charges a fee of $0.25 per mile driven)

Since you know:

m = 200 miles         Substitute/plug it into the equations to see the total cost for each company

C(m) = 0.10m + 41         Plug in 200 for "m"

C(200) = 0.10(200) + 41

C(200) = 20 + 41

C(200) = 61               They charge $61 for 200 miles

T(m) = 0.25m       Plug in 200 for "m"

T(200) = 0.25(200)

T(200) = 50             They charge $50 for 200 miles

Tom's Car Rentals offers a better price for a one-day rental because for 200 miles, they charge $50 while Speedy's charges $61, which is $11 more expensive.

Okay, so let's start by setting up this problem:
(original number=x)(percentage=.06)=(percentage of original number)
So it should look like this:
(x)(.06)=51 Now we should divide .06 from each side
x=850 And there we go! 850 is the answer.
i hope this help

The question is what does x mean. And x = 2/25 and in decimal form x equals 0.08.

  7) K'(1, 1), N'(4, 0), Q'(4, 4)

  9) F'(4, 2), W'(4, 5), K'(3, 2)

Step-by-step explanation:

When you are not sure about reflections and rotations, it can be useful to actually draw a graph. The line of reflection is the perpendicular bisector of the segment connecting a point with its image. That is, the image is the same distance from the line on the other side. A point that is on the line of reflection is "invariant," it doesn't move.

__

7) Reflecting across the x-axis changes the sign of the y-coordinate. That is all. Any point on the x-axis (y=0) is unchanged. The transformation is ...

  (x, y) ⇒ (x, -y)

__

9) Reflecting across a vertical line changes the x-coordinate. The new value of x will be ...

  x' = 6 - x

The "6" is double the x-coordinate of the vertical line. The transformation is ...

  (x, y) ⇒ (6-x, y)

_____

Derivation of the formula for reflection on x=3

In general if M is the midpoint of a point (A) and its reflection (A'), then we have ...

  M = (A +A')/2

  2M = A + A'

  2M -A = A'

When a point is reflected across a vertical line, all of the y-coordinate values remain unchanged. So, for A=(x, y) and M=(3, y), we have ...

  A' = 2(3, y) -(x, y) = (6-x, 2y-y)

  A' = (6 -x, y)

So, the reflection transformation across the line x = 3 is ...

  (x, y) ⇒ (6-x, y)

Below in bold.

Step-by-step explanation:

Amount originally in the cup = amount she drank + amount remaining

= 17 * 4.5 + 148.5

=  76.5 + 148.5

= 225 milliliters.

The time she takes to drink the 148.5 mL = 148.5 / 4.5

= 33 seconds.

So time to drink it all = 17 +33 = 50 seconds.

 A. (-∞, -2) ∪ (-1, 0)

              B. (2, -1) ∪ (0, ∞)

               C. None

Step-by-step explanation:

Let's look at the graph from left to right to see what direction it is going:

It is increasing (↑) from x = -∞ to x = -2     It is (↓) decreasing from x = -2 to x = -1It is increasing (↑) from x = -1 to x = 0 It is (↓) decreasing from x = 0 to x = ∞

There are no straight lines so there are no intervals when it is constant.
