Write out an equation for the total cost. The price per pound multiplied by the number of pounds will give you the total cost.

Total cost

=

Price per pound

⋅

Number of pounds

Rearrange this algebraically to solve for  

Price per pound

. To do this, divide both sides of the equation by  

Number of pounds

to get  

Price per pound

by itself.

Total cost

Number of pounds

=

Answer:

Answer is 3% more peat and 9% more vermiculite.

Step-by-step explanation:

The weight of the initial potting mixture is not given, but the percentage amounts of peat moss & vermiculite are given.

The weight of the new potting mixture is 100lb.

For the new mixture to have 15% peat and 15% vermiculite,

The amount of peat that must be added is 3% of the peat in the initial mixture.

Hint: subtract 12 from 15. Retain the percentage sign.

The amount of vermiculite that must be added is 9% of the vermiculite in the initial mixture.

Hint: subtract 6 from 15. Retain the percentage sign, as that is the scale of measurement here.

Answer:

x + (x +3) + (x +7) = 37

3x = 27

x = 9

Longest side = x + 7 = 16 cm

Step-by-step explanation:

Answer:

16cm

Step-by-step explanation:

x + x + 3 + x + 7 = 37          (make all sides equal 37)

3x + 10 = 37                        (Add x's and coefficiants together)

    -10     -10                        (subtract 10 from each side)

3x = 27                               (divide 27 by 3)

x = 9                                    (answer)

x, x + 3, x + 7                      (finding longest length)

9, 9 + 3, 9 + 7                     (Substitute 9 for x)

9cm, 12cm, 16cm               (add each together)

16cm                                   (answer)

Answer:

(f + g)(x) = |3x + 5| + 13

Step-by-step explanation:

Given

f(x) = |3x + 5| + 6

g(x) = 7

Required

Find (f + g)(x)

In functions

(f + g)(x) = f(x) + g(x)

Meaning that, we simply add the given functions together

So, we have that:

(f + g)(x) = |3x + 5| + 6 + 7

(f + g)(x) = |3x + 5| + 13

Hence, (f + g)(x) when calculated equals |3x + 5| + 13

Answer:

$951

Step-by-step explanation:

EOQ = Sqroot{(2*Annual Demand*Ordering cost)/Holding cost}

= Sqroot{(2*250*12*100)/(0.2*30)}

= 317 Units Approximately

Total Holding cost = Average Inventory * Holding cost per unit

= (EOQ/2)*Holding cost per unit

= (317/2)*(0.2*30)

= $951

So by knowing the holding cost and the percentage that it represents, we want to find the total cost of the masks. We will find that the cost is $150.

We know that the holding cost is 20% of the cost of a single mask, so if the cost of a mask is C, the holding cost is:

(20%/100%)*C = 0.2*C

And we know that this is equal to $30, so we get:

0.2*C = $30

Now we can solve this for C, the total cost of a mask:

C = $30/0.2 = $150.

Answer:

Answer is B

Step-by-step explanation:

If you are unsure about where to start, you could always plot some numbers down until you see a general pattern.

But a more intuitive way is to determine what happens during each transformation.

A regular y = |x| will have its vertex at the origin, because nothing is changed for a y = |x| graph. We have a ray that is reflected at the origin about the y-axis.

Now, let's explore the different transformations for an absolute value graph by taking a y = |x + h| graph.

What happens to the graph?

Well, we have shifted the graph -h units, just like a normal trigonometric, linear, or even parabolic graph. That is, we have shifted the graph h units to its negative side (to the left).

What about the y = |x| + h graph?

Well, like a parabola, we shift it h units upwards, and if h is negative, we shift it h units downwards.

So, if you understand what each transformation does, then you would be able to identify the changes in the shape's location.

Answer:

[tex]V(x) = 66.02\ \text{in}^3 \ \vert \ _x_=_1_._9_6[/tex]

Step-by-step explanation:

The volume of a rectangular prism is found using the formula: V = lwh.

In order to write a formula in terms of the variable x, we need to write expressions for the length, width, and height of the rectangle.

We can say the length is the bottom of the base of the prism. To find this value, we can subtract x and x from 15 and divide this by 2, since there are two equal rectangles (base and lid).

We can say the width is the side of the base of the prism. To find this value, we can subtract 2x from 10.

The height of the prism can be x, which is the labeled length of the rectangle next to the base and lid.

Now we are able to write a formula for volume in terms of x.

The domain of the volume is where x > 0, 2x < 10, and 2x < 15.

This is because our expressions for length ([tex]\frac{15-2x}{2}[/tex]), width (10-2x), and height (x) cannot go below 0, because you cannot have a negative value for measurement - realistically.

Therefore, if we take into account all of these restrictions on x, the domain is where 0 < x < 5.

x cannot be > 5 since that would not satisfy 2x < 10.

The domain of V for this problem situation is D: (0, 5).

In order to find the maximum volume of the rectangular prism using our formula we derived, we can use the idea of optimization in calculus.

Start by taking the derivative of V(x).

Set the derivative equal to 0. This gives us the critical point(s) in order to determine the extreme values of the function, aka where the max and min occur.

Solve for x by using the quadratic formula.

Input this into your calculator and you should get:

We are going to use x = 1.96 since 6.37 is NOT in the domain of V(x).

Now, since this value of x is going to give the maximum volume of this rectangular prism, or cardboard box, we can plug it back into the V(x) equation for volume to determine the maximum volume of the box.

The maximum volume of the cardboard box is 66.02 in³ and the value of x that gives this is 1.96.
