Answer:

$733.80

Step-by-step explanation:

To calculate the profit, you use 7.85m + 8.85d

Since m = 45 and d = 43,

his profit = (7.85 × 45) + (8.85 × 43)

              = 353.25 + 380.55

              = 733.80

∴The restaurant manager's profit in dollars is $733.80.

Hope this helps

A recipe requires 3/4 cups of water targa has a measuring cup that is marked only in ounce but she knows that 8 ounces is equiva
bulgar [2K]

Answer:

6 ounces of water

Step-by-step explanation:

In this question, we are asked to calculate the amount in ounce that would be added to the recipe.

From the question, we can see that the recipe requires 3/4 cups of water.

From the question also, we can also see that one cup equals 8 ounces.

Now to know the amount of water that is to be added, what we need to do is to simply multiply the fraction of water in the recipe by 8 ounces

This is equal to 3/4 * 8 = 6 ounces

Hence, she needs to add a total of 6 ounces of water to the recipe

Liza is driving to her sister's house 360 miles away. After 4 hours, Liza is 2 3 of the way there.
DochEvi [55]

Liza is driving to her sister's house 360 miles away. After 4 hours, Liza is 2/3 of the way there.   How many more hours  does Liza have to drive?

<em><u>Answer:</u></em>

Liza need to drive 2 more hours to reach her sister house

<em><u>Solution:</u></em>

Given that Liza is driving to her sister's house 360 miles away

So total distance = 360 miles

After 4 hours, Liza is 2/3 of the way there.

\frac{2}{3} r d \text { of total distance }=\frac{2}{3} \times 360=240

So Liza has covered 240 miles in 4 hours

Let us find the speed

<em><u>The relation between distance and speed is given as:</u></em>

speed = \frac{distance}{time}

speed = \frac{240}{4} = 60

Thus speed = 60 miles per hour

Assuming speed is same throughout the journey, let us calculate the time taken to complete remaining distance

Remaining distance = 360 - 240 = 120 miles

Now distance = 120 miles and speed = 60 miles per hour

time taken = \frac{distance}{speed}\\\\time taken = \frac{120}{60} = 2

Thus Liza need to drive 2 more hours to reach her sister house

Answer:

The answer to your question is:

x = 1

y = 1

z = 0

Step-by-step explanation:

                                -2x + 2y + 3z = 0             (1)

                                -2x - y + z = -3                  (2)

                                 2x + 3y + 3z = 5              (3)

Solve (1) and (2)  

Multiply 2 by 2

                                 -2x + 2y + 3z = 0

                                 -4x -2y   + 2z = -6

                                -6x          + 5 z = -6        (4)

Solve (2) and (3)

Multiply 2 by 3

                               -6x - 3y + 3z = -9

                                2x + 3y + 3z = 5

                               -4x         + 6z = -4           (5)

Solve (4) and (5)

Multiply (4) by 2 and (5) by -3

                           -12x    + 10 z = -12

                            12x    -  18z   = 12

                                         -6z = 0

                                          z = 0

Then

            -4x + 6(0) = -4

           -4x = -4

            x = -4/-4

            x = 1

Finally

                 -2(1) - y + (0) = -3      

                -2 - y = -3

                 -y = -3 + 2

                 y = 1
