A candy manufacturer has 130 pounds of chocolate-covered cherries and 170 pounds of chocolate-covered mints in stock. He decides
Ilia_Sergeevich [38]

Answer:

He should prepare 260 pounds of first mixture and 0 pounds of second mixture

Step-by-step explanation:

Let x be the total quantity ( in pounds ) of cherries and mints in the first mixture and y be the total quantity in second mixture,

Since, first mixture will contain half cherries and half mints by weight,

That is, in first mixture,

Cherries = \frac{x}{2}

Mints = \frac{x}{2},

While, second mixture will contain one-third cherries and two-thirds mints by weight,

That is, in second mixture,

Cherries = \frac{y}{3}

Mints = \frac{2y}{3}

According to the question,

The manufacturer has 130 pounds of chocolate-covered cherries and 170 pounds of chocolate-covered mints in stock,

That is,

\frac{x}{2}+\frac{y}{3} \leq 130

\frac{x}{2}+\frac{2y}{3}\leq 170

Also, pounds can not be negative,

x ≥ 0, y ≥ 0,

Since, the first and second mixture must be sell at the rate of $2.00 per pound and $1.25 per pound respectively,

Hence, the total revenue,

Z = 2.00x + 1.25y

Which is the function that have to maximise,

By plotting the above inequalities,

Vertex of feasible regions are,

(0,255), (180, 120) and (260, 0),

Also, at (260, 0), Z is maximum,

Hence, he should prepare 260 pounds of first mixture and 0 pounds of second mixture in order to maximize his sales revenue.

The values in the table below represent Function B, which is a linear function.
yan [13]
<h3>1. Compare Functions B and L by determining which one has the greater rate of change.</h3>

The rate of change is expressed as the ratio between a change in one variable relative to a corresponding change in another. On the other hand, a linear function is given as the form:

y=mx+b

And m is the rate of change we are looking for. For Function B we have a Table and the slope can be found by choosing two points, therefore:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ Choosing \ (1,5) \ and \ (3,11) \\ \\ m=\frac{11-5}{3-1}=3

As you can see y=6x+4 has a rate of change of 6 while the function of the table has a rate of change of 3.

<em> In conclusion,</em> y=6x+4 <em>has the greater rate of change</em>

<h3>2. which one has a greater y-intercept?</h3>

We need to get the equation that rules the points given on the table. Two-Point Form of the Equation of a Line is:

y-y_{1}=m(x-x_{1}) \\ \\ We \ know \ m=3 \\ \\ y-5=3(x-1) \therefore y-5=3x-3 \therefore y=3x+2

As you can see y=6x+4 has a y-intercept of b=4 while the function of the table has a y-intercept of b=2

<em> In conclusion,</em> y=6x+4 <em>also has the greater y-intercept</em>

The figure below is a regular pentagon. If mZBAE = 5x + 3, find the value of x.
Pepsi [2]

Answer:

x = 21

Step-by-step explanation:

For a pentagon, n = 5.

Each angle measures:

(n - 2)180/5 = (5 - 2)(180)/5 = 108

5x + 3 = 108

5x = 105

x = 21

Nardia plots points showing equivalent ratios on the coordinate plane below. Mc018-1. Jpg Which ordered pair would represent a r
timurjin [86]

The ordered pair that would represent a ratio that is equivalent to those shown is (8, 12)

<h3>Ratio and proportions</h3>

From the given diagram, we can create two coordinate points which are (2, 3) and (4, 6)

We need to determine the ordered pair would represent a ratio that is equivalent.

Multiplying the coordinate by a scale factor of 4 will give

A(2, 3) = A'(4(2), 4(3)) = (8, 12)

Hence the ordered pair that would represent a ratio that is equivalent to those shown is (8, 12)
