christy uses glass beads to make braclets and necklances it takes her 30 minutes to make a bracelet and 45 minites to make a nec
shtirl [24]

Christy should make at least 30 bracelets and at most 40 necklaces to maximize profit

<h3>How to determine how many bead of each type of bracelets and necklaces should Christy make to maximize his​ profit?</h3>

The given parameters can be represented in the following tabular form:

                       Bracelet (x)    Necklace (y)    Total              

Labor (hour)        0.5                       0.75         40

Profit                    10                         18

From the above table, we have the following:

Objective function:

Max P = 10x + 18y

Subject to:

0.5x + 0.75y <= 40

Because she wants to make at least 30 bracelets, we have:

x >= 30

So, we have:

Max P = 10x + 18y

Subject to:

0.5x + 0.75y <= 40

x >= 30

Express x >= 30 as equation

x = 30

Substitute x = 30 in 0.5x + 0.75y <= 40

0.5 * 30 + 0.75y <= 40

This gives

15 + 0.75y <= 40

Subtract 15 from both sides

0.75y <= 30

Divide by 0.75

y <= 40

Hence, Christy should make at least 30 bracelets and at most 40 necklaces to maximize profit

Please help and show work
gladu [14]

Answer:

A

Step-by-step explanation:

First I converted the fractions into decimals to make it easier to solve.

2 1/2 —> 2.5

1 3/4 —> 1.75

Then I added the two decimals together.

2.5 + 1.75 = 4.25

Then I divided this number by 100 (the number of cups in one bag)

100/4.25=23.529

With this equation I know that one bag lasts 23 full days.

This is almost a month, and so it would not make sense for the answers to be B, C, or D.

Hope this helped

Which equations are equivalent to the expression below ? Check all that apply
taurus [48]

It looks like selections A and C are identical. (Neither is equivalent to 9^x.)

If B is supposed to be 3^(2x), it is equivalent to F and D and to the given expression.

Of course, D evaluates to 9^x, so is equivalent.

Choice E evaluates to 3^(x+2), which is not equivalent to 3^(2x).

The applicable choices appear to be

... B. 3^(2x)

... D. (3*3)^x

... F. (3^x)*(3^x)
