You compare the degrees of the numerator and the denominator.

The numerator has a degree of 0 and the denominator has a degree of 1.

Since the numerator < denominator the degree is 0.

Max is observing the velocity of a runner at different times. After one hour, the velocity of the runner is 5 km/h. After two ho
Valentin [98]

You have velocity 1 of 5 km per hour after 1 hour and velocity 2 of 3 km per hour after 2 hours.


Part A)

Let Velocity = a +bt, with t being the time in hours.

For velocity 1 you have a +b = 5

For velocity 2, you have a + 2b =3

Now subtract velocity 1 from velocity 2:

a +2b - (a+b) = 3-5

Simplify to get b = -2

Now solve for a in the first equation:

a + b =5

Replace b with -2:

a - 2 = 5

a = 7

Now replace a and b in the original formula:

Velocity = 7 -2t


Part B)

Create a table with x and Y values to graph.

X axis would be the time and the velocity would be the Y axis

Your time would be 0 , 1, 2 3 and 4 hours.

Using the final equation from part A, replace t with the hours ans solve for the velocities, which become the y axis:

7 - 2(0) = 7-0 = 7

7 - 2(1) = 7-2 = 5

7 - 2(2) = 7-4 = 3

7 - 2(3) = 7-6 = 1

7-2(4) = 7-8 = -1


Now you have your x and y coordinates to plot on a graph:

(0,7) (1,5) (2,3) (3,1) and (4,-1)

Ella collects 50 bottles to recycle. Of the bottles she collects, 19 are plastic and the rest are glass.
nekit [7.7K]
QUESTION A

The total number of bottles Ella collected is
50


The number of bottles that are plastic is

19

The percentage of bottles that are plastic is

=  \frac{number \: of \: plastic \: bottles}{total \: number \: of \: bottes}  \times 100\%

=  \frac{19}{50}  \times 100\%

= 19 \times 2\%
= 38\%

Therefore 38% of the bottles are plastic.



QUESTION B

The total number of bottles that are glass is
50 - 19 = 31

The total number of bottles Ella collected is
50

The percentage of bottles that is glass is
=  \frac{number \: of \: glass \: bottles}{total \: number \: of \: bottles}  \times 100\%

=  \frac{31}{50}  \times 100\%

= 31 \times 2\%
= 62\%

Therefore 62% of the bottles are glass
