olga55 [171]

Answer: Xavier earned $155.25 last week.

Step-by-step explanation:

To find out how much Xavier earn last week, we need to multiply how much He earns per hour ($11.50) by how many hours He worked last week (13.5h), so:

11.50 * 13.5 = 155.25

155.25 is already round to the nearest penny.

So, Xavier earned $155.25 last week.

Explain how to find the unit rate of water to vinegar

kvv77 [185]

Answer:

Helena uses double the amount of water to the amount of vinegar.

Step-by-step explanation:

A unit rate is a ratio that is used to compare different kinds of quantities.

A unit rate describes how many units of the first quantity corresponds to one unit of the second quantity.

So, unit rate of water to vinegar means how much water is needed corresponding to 1 unit of vinegar.
Formula:

$\text{Unit Rtae} = \displaystyle\frac{\text{Amount of Water}}{\text{Amount of Vinegar}} = \displaystyle\frac{5}{2\frac{1}{2}} = 2$

Thus, for every 1 unit of vinegar, one needs two units of water.

Thus, Helena uses double the amount of water to the amount of vinegar.

Use slopes and y-intercepts to determine if the lines 4x−3y=6 and y=43x−1 are parallel.

inn [45]

Answer:

Since they have the same slope, they are parallel.

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

$y = mx + b$

In which m is the slope. If two lines are parallel, they have the same slope.

4x−3y=6

Placing into the above format:

$3y = 4x - 6$

$y = \frac{4x - 6}{3}$

$y = \frac{4x}{3} - 2$

The slope $m = \frac{4}{3}$

y=4/3x−1

The slope is $m = \frac{4}{3}$

Since they have the same slope, they are parallel.
