A factory stacks boxes according to their weights. To provide stability to the stacks of boxes, heavier boxes are placed at the bottom of the stack, and lighter boxes are placed at the top. However, because of the boxes’ material, a box can only be placed on top of another if its weight is exactly half the weight of the lower box. Also, due to the height of the warehouse ceiling, boxes can only be stacked 4 levels high. The factory director has asked for your help in answering some questions about these boxes.

a. Explain how you would find the weight of each stacked box if you knew the weight of the bottom box. Find the weight of each box in a stack of 4 boxes if the bottom box weighs 10 pounds.
b. Eventually, these stacks of boxes will go onto pallets for shipping. We need to know how much each stack weighs in order to know how many stacks we can put on each pallet, but the bottom boxes do not necessarily weigh 10 pounds. In fact, we don’t know how much they weigh at all! Write and simplify an expression to find the weight of one stack of 4 boxes based on the unknown weight of the bottom box.
c. Each stack needs to weigh less than 100 pounds. Write and solve an inequality to find the maximum weight of the bottom box. What would be the possible range of weights for this box? It may help you to consider a graph of the solution to your inequality.
I rlly need help for c, I got the other 2.

Answers

If the weight of the bottom box is b then the weight of a stack of four boxes is b + b/2 + b/4 + b/8
= 8b/8 + 4b/8 + 2b/8 + 1b/8
= 15/8 b
A stack must weigh less than 100 pounds
15/8 b < 100
b < 100 x 8/15 = 53 1/3 pounds
If boxes have a minimum weight of 1 pound then
for stacks that contain 4 boxes the range of b is [8, 53 1/3)
and if stacks contain 1 to 4 boxes the range of b is [1, 53 1/3)

If the only restriction is a maximum of 100 then the range of b is [0, 53 1/3)

Find the principal which amounts to $918 in 1 year at a simple interest
of 2% per annum

Answers

Answer:

P = $900

Step-by-step explanation:

Simple Interest Formula: [tex]A = P(1+rt)[/tex]

Where A is the final amount,

P = Principal

r = Interest Rate in Percent or [tex]\frac{r}{100}[/tex] per annum

t = time in years

From the information given in the question,

A = $918

r = 2% per annum or [tex]\frac{2}{100}[/tex]

t = 1 year

Lets substitute these values to find P, the principal.

[tex]P(1+(\frac{2}{100} )(1))=918\\P(1+0.02)=918\\1.02P=918\\P = \frac{918}{1.02} \\=$900[/tex]

What is the measure of arc ef

Answers

Answer: [tex]128^{\circ}[/tex]

Step-by-step explanation:

By the inscribed angle theorem, minor arc EG measures 92 degrees.

Since the circumference of a circle measures 360 degrees, arc EF measures [tex]360-140-92=128^{\circ}[/tex]

The measure of the arc EF = 128°.

What is an Arc?

Arc is that part of the circumference of the circle which is formed by two points on the circle.

The angle subtended by an arc on the center of the circle is twice that it subtends on the circumference of the circle.

So,

The measure of arc EG = 2 * 46 = 92

The measure of arc GF = 140°

The complete circle has an angle of 360° at the center

The measure of the arc EF = 360 -mEG - mGF

The measure of the arc EF = 360 - 92 -140

The measure of the arc EF = 128°.

Therefore, The measure of the arc EF = 128°.

A spiral staircase turns $270^\circ$ as it rises 10 feet. The radius of the staircase is 3 feet. What is the number of feet in the length of the handrail

Answers

The number of feet in the length of the handrail is 17.3 ft.

The easiest way to see this is to imagine that we can "unfold" the spiral to create a rectangle

The bottom side of the rectangle is just the arc length of a circle with a radius of 3 ft  turned through 270°= (3/4) of a whole revolution

(3/4) (2pi) (3)  =  (9/2)pi ft =   4.5 pi ft

The side of the rectangle will be the rise of the staircase = 10ft

And the diagonal of the rectangle will be the length of the handrail

We can use the Pythagorean Theorem to solve this

Handrail length = √ [ (4.5 pi)^2 + 10^2 ]  ≈  17.3 ft

2. What is the total cost of a one-way trip?

Answers

There are 3 tolls where Stephanie pays $ 4.05.

What is Distance?

The distance between two points is the length of the path connecting them.

Here,

Distance covered by Stephanie = 12 1/4 miles

                                                     = 12.25 miles

Distance between two toll tax = 3 1/2 miles

                                                   = 3.5 miles

Number of Tolls = Total distance covered / Distance between two tolls

                            = 12.25 / 3.5

                            = 3.5

                            ≈ 3 tolls.

Cost of 1 toll = $ 1.35

Total amount paid on toll = 3 X 1.35

Answer:

  (a)  The number of positive zeros is either 2 or 0. The number of negative zeros is either 2 or 0.

Step-by-step explanation:

The possible numbers of real zeros can be found using Descarte's Rule of Signs.

Rule

When signs of coefficients of terms of the polynomial are listed in order of decreasing degree, the number of sign changes can be counted. That number is the number of possible positive real zeros of the polynomial.

When the signs of odd-degree terms are changed, the number of sign changes becomes the possible number of negative real zeros.

The actual number of real zeros may be less by a multiple of 2. (The zeros may be complex, and complex zeros come in pairs.)

Application

The signs of the terms in the given polynomial are ...

  + - + + + . . . . . 2 sign changes: 2 or 0 positive real zeros

When the signs of odd-degree terms are changed, they become ...

  + + + - + . . . . . 2 sign changes: 2 or 0 negative real zeros

Descarte's rule of signs lets us conclude ...

The number of positive zeros is either 2 or 0. The number of negative zeros is either 2 or 0.

Additional comment

When we graph the function, we find there are no real zeros. All four of the zeros are complex.

Step-by-step explanation:

So the sample space consists of all products for (5 * 1, 5 * 2, 5 * 3.... and the same thing for 6, 7, and 8)

This gives you the sample space: {5, 10, 15, 20, 25, 30, 6, 12, 18, 24, 30, 36, 7, 14, 21, 28, 35, 42, 8, 16, 24, 32, 40, 48}.

The size of the sample space is 4 * 6, since for each number (5, 6, 7, 8), there are 6 products (the dice have six numbers). This means the sample space has 24 combinations, you can also verify this by manually counting the sample space.

Now filtering the sample space so you only get a product that is 28 or higher you get: {30, 30, 36, 28, 35, 42, 32, 40, 48} which has 9 possible combinations that have a product greater than or equal to 28.

The relative frequency for bird is 0.15.

The relative frequency for fish is 0.1

What is relative frequency?

The ratio of the total number of events occurring in a scenario to the number of times an event occurs is known as relative frequency.

Relative Frequency = Subgroup frequency/ Total frequency.

Relative Frequency = f/ n.

where, f = total frequency

n = subgroup frequency

Calculation for the relative frequencies of the pet types:

(1) Relative frequency for dog:

Total frequency is 20.

The frequency for dog is 8.

Relative frequency for dog =  frequency for dog/total frequency

                                             = 8/20

                                             = 0.4

Relative frequency for dog = 0.4.

(2) Relative frequency for cat:

Total frequency is 20.

The frequency for cat is 7.

Relative frequency for cat =  frequency for cat/total frequency

                                             = 7/20

                                             = 0.35

Relative frequency for cat = 0.35.

(3) Relative frequency for bird:

Total frequency is 20.

The frequency for bird is 3.

Relative frequency for bird =  frequency for bird/total frequency

                                             = 3/20

Relative frequency for bird = 0.15.

(4) Relative frequency for fish:

Total frequency is 20.

The frequency for fish is 2.

Relative frequency for fish =  frequency for fish/total frequency

                                             = 2/20

Relative frequency for fish = 0.1.
