The graph shows the amount of money paid when purchasing bags of peanuts at the zoo: a graph is shown. the x-axis is labeled from 0 to 9. the y-axis is labeled from 0 to 13. the four points shown on the graph are ordered pairs 0, 0 and 1, 4 and 2, 8 and 3, 12. these points are joined by a line. the label on the x-axis is bags of peanuts. the title on the y-axis is total cost in dollars. write an equation to represent the relationship between the total cost (y) and the number of bags of peanuts (x). y = 4x y = one-fourth x y = 3x y = one-third x

The equation of the line through the given points is required.

dive the cost by the number of bags for each dot:

4 / 1 = 4

8 / 2 = 4

12 / 3 = 4

This means each bag cost $4

The equation would be Y = 4X, because you would multiply each bag bought (X) by $4 to get the total cost (Y).

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
