Gianna makes $18 per hour.

Step-by-step explanation:

Given Gianna makes 90$ for 5 hours. That means she should make $\frac{90}{5}$ $ = 18$ every hour.

Therefore we have:

HOURS DOLLARS

1 18

2 36

3 54

4 72

5 90

6 108

7 126

For the tabular column mark Hours on the x - axis and Dollars on the Y - axis. It can be plotted from the above table easily.

If Gianna works for 8 hours she would have made 8 X 18 = 144$.

So, she will earn 144$ in 8 hours.

To make 60$ she would have to work $\frac{60}{18}$ hours = 3.33 hours.

A train is traveling at a constant speed and goes a distance of 7 ½ kilometers in 6 minutes. The train will continue to travel a

g100num [7]

Answer:

m = 1.25d

Step-by-step explanation:

A train is traveling at a constant speed and goes a distance of 7 ½ kilometers or 7.5 km in 6 minutes.

6 min = 7.5 km

1 min = (7.5/6) km/min

= 1.25 km/min

In m min, (7.5/6)d is travelled by the train. Hence, the relation between d and is :

$m=\dfrac{7.5d}{6}\\\\m = 1.25d$

Hence, this is the required solution.

The coordinates of the vertices of △JKL are J(3,4) K(3,1) L(1,1). coordinates of the vertices of △J’K’L’ are J’(-3,-5) K’(-3,-2)

Vera_Pavlovna [14]

Given coordinates of △JKL are J(3,4) K(3,1) L(1,1) and

△J’K’L’ are J’(-3,-5) K’(-3,-2) L’(-1,-2).

We know, when we rotate a figure about 180 degrees about the origin, the coordinates (x,y) would result (-x,-y).

So, first step should be "Rotation of 180 degrees about the origin."

After rotating 180 degrees about the origin, J(3,4) K(3,1) L(1,1) points would transform to J(-3,-4) K(-3,-1) L(-1,-1).

Now, we will move 1 unit down. So the new coordinate of (-x,-y) would become (-x, -y-1) and J(-3,-4) K(-3,-1) L(-1,-1) coordinates would transform to exactly J(-3,-4-1) K(-3,-1-1) L(-1,-1-1) => J’(-3,-5) K’(-3,-2) L’(-1,-2).

And those are the coordinates of transformed triangle △J’K’L’.

So, the steps of transformations are as following:

Setp 1) Rotation of 180 degrees about the origin.

Setup 2) Translation 1 unit down.
