Answer:

3 hours was spent on labor

Step-by-step explanation:

<u>Key skills needed: Creating an equation, Solving an equation</u>

1) The total cost is 329.00 (or 329). The parts are 125.00 (or 125), and the labor is 68 per hour.

2) If we say h is the number of hours of labor, then we can create this equation --> 68h (or 68 multiplied by "h") 68h would be the cost of labor, and we need to find the number of hours (h) as a number.

3) We can create this equation --> 329 = 125 + 68h

--> This equation can be made as the total cost (329) is equal to the parts (125) and the labor (68h)

4) Subtract 125 from both sides to get 68h by itself

--> 329 - 125 = 204 so 204 = 68h

--> Divide by 68 on both sides (204 divided by 68 is 3)

--> This means that h is 3.

Therefore, the number of hours spent on labor is 3.

Answer:

y = 250x

Step-by-step explanation:

<em>The options are not given; however, the question can still be answered.</em>

Given

Direct Proportion:

In 20 minutes, y = 250 bottles

Required

Determine the graph

<em>In the first 20 minutes, y = 250</em>

<em>In the next 20 minutes, y = 250 + 250 = 500</em>

<em>In the next 20 minutes, y = 500 + 250 = 750</em>

<em />

This gives a arithmetic sequence:

250, 500, 750, ........

Next, is to determine the equation of the sequence using;

T_n = a + (n - 1)d

In this case;

T_n = y

x = n

a = 250

d = 750 - 500 = 500 - 250 = 250

Substitute these values in the above formula;

y = 250 + (x - 1) * 250

Open Bracket

y = 250 + 250x - 250

Collect Like Terms

y = 250x + 250 - 250

y = 250x

Hence; the graph that shows the given description is the graph with equation y = 250x

Yvette uses 6grams of tea leaves to make 24 fluid ounces of tea last week she made 288. Fluid ounces of tea how many grams of te
miskamm [114]

Answer: 72 grams of tea

Step-by-step explanation:

From the question, we are informed that Yvette uses 6grams of tea leaves to make 24 fluid ounces of tea. This means that for 1 gram of tea leaves, she'll use:

= 24/6

= 4 fluid ounces of tea

Since, 1 gram of tea leaves will be used to make 4 fluid ounces of tea, therefore, the number of grams of tea leaves that will be used to make 288 fluid ounces of tea will be:

= 288/4

= 72 grams of tea
