A company has released the following possible designs for a new cereal box. The cost of production depends upon the cost of materials, which is determined by how much material is used. The amount of material used is equal to the surface area of the package plus some overlap. The amount of product contained in the package is the volume of the packaging.

Find the surface area and volume of the following possible cereal boxes. Determine the cost of making the cereal box assuming that cardboard costs $0.05 per square inch.

Matilda and her family took a trip to Yellowstone National Park to see Old Faithful
erupt. Matilda was standing 125ft from the blast. The blast rose 100ft in the air.
What is the angle from Matilda to the top of the blast?

Answers

Using the slope concept, it is found that the angle from Matilda to the top of the blast was of 38.66º.

What is a slope?

The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.

In this problem, the vertical change is of 100 ft, while the horizontal change is of 125 ft, hence:

[tex]\tan{\alpha} = \frac{100}{125}[/tex]

[tex]\alpha = \arctan{\left(\frac{100}{125}\right)}[/tex]

[tex]\alpha = 38.66^\circ[/tex]

The angle from Matilda to the top of the blast was of 38.66º.

The marked price of a car is $49,500. A person can pay deposit of 30%
and interest at 12% per annum is charged on the outstanding balance.
The total amount payable is to be paid in 2 1/2 years. A) the amount of
each monthly installment b) The hire purchase of the car

Answers

The amount of each monthly installment is $1,294 and the hire purchase of the car is: $4,158.

Monthly installement

a. Monthly installment

2 1/2 years=30 months

First step

Amount payable=[49,500×(1-.30)] /30 months

Amount payable=(49,500×.70)/30 months

Amount payable=$34,650/30 months

Amount payable=$1,155

Second step

Amount of monthly installment=[$1,155×(1+0.12)

Amount of monthly installment=$1,155×1.12

Amount of monthly installment=$1,293.6

Amount of monthly installment=$1,294 (Approximately)

b. Hire purchase

Hire purchase=$1,155×.12×30 months

Hire purchase=$4,158

Therefore the amount of each monthly installment is $1,294 and the hire purchase of the car is: $4,158.

The volume of any shape is the amount of space in it.

The volume of the cylinder is 1570 square units

How to determine the volume?

The question is incomplete. Assume the following parameters

Shape = Cylinder

Radius, r = 10

Height, h = 5.

The volume of a cylinder is:

V = πr^2h

So, we have:

V = 3.14 * 10^2 * 5

Evaluate the product

V = 1570

Using the assumed values, the volume of the cylinder is 1570 square units

Find the measure of the red arc or chord in ⊙C. The measure of arc XYZ is a °

Answers

The points on the red arc are points A and B

The measure of the red arc is 75 degrees

How to determine the measure of arc XYZ?

From the complete question, we have:

Angle DCE = 75 degrees

By vertical angles theorem,

Angle ACB = Angle DCE = 75 degrees

So, we have:

Angle ACB = 75 degrees

The measure of the red arc is the same as the measure of the angle ACB.

So, we have:

Red arc = 75 degrees

Hence, the measure of the red arc is 75 degrees

A. 1/7

D.8/7

Answers

The correct option is 3/7

Step by Step Explanation:

Given:

line passing through points (2,5) and (9,8)

To find:

Slope of the line

Solution:-

Here, to find the slope of line passing through two points x₁,x₁ and y₁,y₂ is given by:-

[tex]\sf m=\frac{y_2 - y_1}{x_2 - x_1} [/tex]

where,

x₁ = 2

x₂ = 9

y₁ = 5

y₂ = 8

Therefore putting the values , we get

[tex] \sf \: m=\frac{y_2 - y_1}{x_2 - x_1} \\ \\ : \longrightarrow \: \frac{8 - 5}{9 - 2} \\ \\ : \longrightarrow \: \frac{3}{7} [/tex]

Hence, the slope of line passes through the points (2, 5) and (9, 8) is 3/7.

The depth of the water at the end of a pier changes periodically along with the movement of tides. on a particular day, low tides occur at 12:00 a.m. and 3:30 p.m., with a depth of 3.25 meters, while high tides occur at 7:45 a.m. and 11:15 p.m., with a depth of 8.75 meters. which of the following equations models d, the depth of the water in meters, as a function of time, t, in hours? let t = 0 be 12:00 a.m. d = negative 3.75 cosine (startfraction 4 pi over 31 endfraction t) 5 d = negative 3.75 cosine (startfraction 4 pi over 29 endfraction t) 5 d = negative 2.75 cosine (startfraction 4 pi over 31 endfraction t) 6 d = negative 2.75 cosine (startfraction 4 pi over 29 endfraction t) 6

Answers

In this exercise we have to calculate the value of the water depth, so we have: d=5.5Cos(12t)+6

What are periodic waves?

A periodic wave is a wave with a repeating continuous pattern that determines its wavelength and frequency

Putting together some information given in the statement we have:

The minimum depth of 3.25 m occurs at 12:00 am and at 3:30 pm.Therefore the period t=0 will be 12:00 am.The maximum depth of 8.75 m occurs at 7:45 am and at 11:15 pm.

Knowing that the formula will be given by an equation similar to:

[tex]d=acos(bt)+k[/tex]

Where:

d = depth, mt = time, hoursa= amplitude

The amplitude difference is given by:

[tex]8.75-3.25=5.5\ m[/tex]

The mean depth is:

[tex]k=\dfrac{(3.25+8.75)}{2}=6\ m[/tex]

Then writing the equation with;

[tex]d=acos(bt)+k\\\\d=5.5cos(12t)+6[/tex]

Hence the value of water depth will be d=5.5Cos(12t)+6

2x + 5y = 20
6x - 5y = 12

Answers

Answer:

is this a question?

Step-by-step explanation:

If you’re asking to solve a system of equations, then x=4 and y= 12/5 or 2.4

First Solve 2x+5y=20 for x

Add -5y to each side
2x=5y-20

Divide both sides by 2
x= -5/2y +10

Next substitute -5/2y +10 for y in the equation 6x-5y=12

6(-5/2y+10) -5y=12
-20y+ 60= 12

Then simplify again by adding -60 to each side
-20y= -48

Then divide by -20 on each side

Y= 12/5 (or 2.4)

Now to find x substitute 12/5 for y in x= -5/2y+10

X= -5/2(12/5) +10

X= 4

So X=4 and Y= 12/5 or 2.4

A college professor wants to survey a sample of students taking his course. Here are some details about his course:

He teaches 5 sections of the course.

There are 250 total students across those sections.

There are 50 graduate students and 200 undergraduate students taking the course.

Each section has about 50 students (some graduate and some undergraduate).

The professor wants to take a sample of 30 students for a survey. He suspects that opinions on the survey may differ the most based on student type (graduate or undergraduate), so he wants to design his sample to take that into account. Which of these strategies will accomplish his intended design?

a. Randomly select 6 students from each section for the survey.

b. Randomly select 6 graduate students and 24 undergraduate students for the survey

c. For each section, randomly select one of the first 8 students to arrive to class, and every 8th student thereafter to take the survey.

d. Randomly select one of the sections and give the survey to every student in that section

Answers

Answer: B, Randomly select 6 graduate students and 24 undergrad students for the survey.

Step-by-step explanation: This guarantees that each type is proportionately represented in the survey.

Not A because it risks too many or too few graduate students. It is not C because again, it risks too many or too few graduate students. It is not D because each section has about 50 students and the professor only wants 30 in his sample.

Answers

The expression that represents the volume of the composite figure is (1/2)* (4.4)*(2)*(5) + (1/3)* (1/2)*(4.4)*(2)*(3.9)

What will be the volume of the composite figure?

The volume of the composite figure will be the sum of the volume of the prism and the volume of the pyramid.

The Volume of the prism = Area of the base * height of the prism

Area of the base = 1/2*4.4 *2

Height of the prism =5

So, the Volume of the prism = (1/2)* (4.4)*(2)*(5)

The volume of the pyramid = 1/3 *(area of the base) * (height of the pyramid)

Area of the base of the pyramid = 1/2*4.4 *2

Height of the pyramid =3.9

So, the volume of the pyramid = (1/3)* (1/2)*(4.4)*(2)*(3.9)

So, total volume = (1/2)* (4.4)*(2)*(5) + (1/3)* (1/2)*(4.4)*(2)*(3.9)

Hence, the expression that represents the volume of the composite figure is (1/2)* (4.4)*(2)*(5) + (1/3)* (1/2)*(4.4)*(2)*(3.9)
