Answer:

<em>a) She started walking back</em>

<em>b) 0.13 km/min</em>

Step-by-step explanation:

The graph shows the distance traveled by Jo. She starts her journey (t=0) at a distance of 0 Km since the graph passes through the origin (0,0).

a) Ten minutes later she is at a distance of 1 km from the starting point and then the distance starts to drop. This means that at t=10 minutes, she started walking back.

b) To calculate the speed for the last 30 minutes of journey, we find the slope of the line. Select the points (30,0) and (60,4).

If a given line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

\displaystyle m=\frac{y_2-y_1}{x_2-x_1}

Substituting:

\displaystyle v=\frac{4-0}{60-30}=\frac{4}{30}

v=0.13 km/min

If Victor were to put apples in bags so that there were 2 kg in each, then he would use 9 more bags than if he were to place 3 k
Cerrena [4.2K]
Let the number of bags that he would have been used to put 3 kg of apples be x. Thus the number of bags that would be used to put 2kgs will therefore be (x+9), hence the total number of kgs the bags will hold will be given by:
3*x=3x kgs
2(x+9)=(2x+18) kgs
since the total weights are the same then:
2x+18=3x
hence
18=3x-2x
18=x
thus the number of bags required to put 3 kgs of apples will be 18. Thus the total Kgs of apples was:
3x
=3*18
=54 kgs

The amount of tax for each camera is $5.25 and the tax rate is 6%. Explain how the equation: (Original Cost)(Percent) = Tax Amou
Degger [83]

x(1.06)=5.25

The reason it is 1.06 is because it is the original cost plus tax. You can divide each side by 1.06 to get x roughly equals 4.95.

So $4.95 is roughly what the camera costs rounded to the nearest cent.
