Well you pay 50$ for the first one, for the second one your paying 12.50 less and for the third one your paying 25 less, if you add them together you get 112.5, it originally would have costed 150, so you would subtract 150 - 112.5, which equals 37.5 so she saved 37.5 dollars on the rings(Here is a quick simple short way to do it.. she payed 12.50 less and 25 less that added together is 37.5)

What equation models the data in the table if d = number of days and c = cost?
dedylja [7]

Answer:

c=3d

Step-by-step explanation:

What equation models the data in the table if d = number of days and c = cost? Days Cost 2 6 3 9 5 15 6 18

Answer: An equation is a statement used to show the relationship between variables and shows the equality between two expressions. We want to find the relationship between the number of days and the cost.

Given that:

Days  Cost

2          6

3          9

5         15

6         18

Lets take the ratio of days to cost using the first row:

\frac{d}{c}=\frac{2}{6}\\  \frac{d}{c}=\frac{1}{3}\\c=3d

The relationship c = 3d is true for all values of days and cost

The circular blade on a saw has a diameter of 7.5 inches and rotates at 2400 revolutions per minute.
Archy [21]
For a:
    
       (2400*2*PI)/60(seconds) = 80 PI RAD/Sec

For b: 
   
        arc length s= radius r * central angle(in radians) 

                          = ((80*pi*7.5)/(2*pi)
                          =25

If FX) = 3x+6, which of the following is the inverse of Fx)?
LenaWriter [7]

Answer:

C. F'(x) = x - 6 / 3

Step-by-step explanation:

y = 3x + 6

x = 3y + 6 \\ x - 6 = 3y + 6 - 6

\frac{x - 6}{3}  =  \frac{3y}{3}

y =  \frac{x - 6}{3}

f1 =  \frac{x - 6}{3}
