Final grades are often computed using weighted averages. Some college professors use complicated weighted averages. Your college professor tells you he will give a 33%-67% split on grades between tests and homework where whichever average is higher will be the 67%. What will your final grade be if your homework average is 68 and your test average is 72? ​

Answers

Answer 1

Answer:

Using weighed averages, it is found that the final grade is was of 82.03.

The weighed average, which represents the final grade, is given by the sum of the grades multiplied by it's weights.

The higher grade has a weight of 67%.

The higher grade was of 85, on homeworks.

The lower grade has a weight of 33%.

The lower grade was of 76, on the test average.

Jessica needs to rent a moving truck for one day. She can choose to rent a moving truck from Rentals Plus or from Speedy Move. At Rentals Plus, it costs $5.24 to rent a moving truck for one day, plus $4.46 per mile driven. At Speedy Move, it costs $85.24 to rent a moving truck for one day, plus $0.46 per mile driven. How many miles would Jessica have to drive for the cost to rent a moving truck for one day to be the same at Rentals Plus and Speedy Move?

Answers

Jessica would have to drive 20 miles for the cost to rent a moving truck for one day to be the same at Rentals Plus and Speedy Move.

How find how many miles would Jessica have to drive

Let's assume the number of miles driven is represented by 'm'. The cost of renting a moving truck for one day at Rentals Plus can be calculated using the equation:

Cost at Rentals Plus = $5.24 + $4.46 * m

Similarly, the cost of renting a moving truck for one day at Speedy Move can be calculated using the equation:

Cost at Speedy Move = $85.24 + $0.46 * m

To find the number of miles that makes the costs equal, we can set up the equation:

$5.24 + $4.46 * m = $85.24 + $0.46 * m

By rearranging the equation, we can solve for 'm':

$4.46 * m - $0.46 * m = $85.24 - $5.24

$4 * m = $80

m = $80 / $4

m = 20

Therefore, Jessica would have to drive 20 miles for the cost to rent a moving truck for one day to be the same at Rentals Plus and Speedy Move.

Charlie has 480 cards, Jack has 520 cards and John 380 cards. How many cards must Charlie and Jack give to John so they can have the same number of cards?​

Answers

Charlie and Jack need to give John 70 cards each so that they all have the same number of cards.

To find the number of cards that Charlie and Jack must give to John so that they all have the same number of cards, we need to find the average number of cards.

The total number of cards is 480 + 520 + 380 = 1380.

The average number of cards is 1380 ÷ 3 = 460.

To get to this same average, Charlie and Jack together need to give John half of the difference between their total number of cards and the average number of cards.

Half of the difference between their total number of cards and the average number of cards is:

(520 + 480) / 2 - 460 = 70

Therefore, Charlie and Jack together need to give John 140 cards in total, which is twice the amount they need to give each.

2) A 25 foot ladder leans against a house. The base of the ladder is 7 feetaway from the house. What

Answers

Answer is 35 ft height of house

Step by step

Using Pythagorean theorem, we can find the height of the right triangle

We know a= 7, we know c= 25, we need to find b

a^2 + b^2 = c^2

7^2 + b^2 = 25^2
49 + b^2 = 625
Subtract 49 from both sides to solve b
49 - 49 + b^2 = 625 - 49
b^2 = 576
Take square root of both sides

√ b^2 = √ 576
b = 24 ft

Now according to the drawing, the ladder did not go to the top of the house, we need to add 11 ft to 24 ft = 35 ft total height

for any integer p, show that p^3+11p will always be a multiple of 6

Answers

By the principle of mathematical induction, it has been proved that

\(p^3 + 11p\) is divisible by 6

What is Principle of mathematical induction?

Let the statement be given by P(n). At first P(n) is proved to be true for 1. Then it is assumed that P(n) is true for all n. If P(n) is true for (n+1) then by Principle of Mathematical induction, P(n) is true for all natural numbers

The given expression is \(p^3 + 11p\)

For p = 1

\((1)^3 + 11 \times 1\\12\)

which is a multiple of 6

Let it be true for p = m

\(m^3 + 11m\) is a multiple of 6

\(m^3 + 11m = 6k\), where k is any integer

For p = m + 1

\((m+1)^3 + 11(m+1) \\m^3+3m^2+ 3m +1+11m+11\\m^3+11m +3m^2+3m+12\\m^3+11m + 3m(m+1) + 12\)

Now,

\(m^3 + 11m\) is divisible by 6

We know that the product of two consecutive integers are divisible by 6

\(3m(m+1)\) is divisible by 6

12 is divisible by 6

\((m+1)^3 + 11(m+1)\) is divisible by 6

So it is true for p = m + 1

By the principle of Mathematical induction, it is true for all natural numbers and eventually for all integers

What is a ratio and how does it apply to math and daily life?

A mathematical phrase that compares two values is called a ratio. It is written as the product of the division of two different quantities. As in 2:1 or 2/1, ratios are frequently expressed as a fraction or with a colon.

Mathematicians employ ratios in many different contexts, such as arithmetic, algebra, and geometry. They are used to compare amounts, identify equivalent values, and resolve proportional and rate-of-change issues.

Convert the ratios in their simplest form:

3 to 4 can be simplified by dividing both terms by their greatest common factor, which is 1. Therefore, 3 to 4 is already in its simplest form.

10 to 12 can be simplified by dividing both terms by their greatest common factor, which is 2. So, 10 to 12 simplifies to 5 to 6.

2 to 1 is already in its simplest form.

To find the area subtract the area of the semicircle from the area of the rectangle.

Although the line isn’t there, if you imagine there is one, then you will see that you form a rectangle which is the same line as the semicircle’s diameter.

The area of rectangle is:

⇒ \(A = lw\)

⇒ \(A = (14)(8)\)

⇒ \(A = 112cm^{2}\)

The area of the semicircle;

⇒ \(A = \frac{1}{2}\pi r^{2}\)

⇒ \(A = \frac{1}{2}\pi (7)^{2}\)

*Note here that the radius is half the diameter, so it is 7cm, not 14cm

⇒ \(A = 76.97cm^{2}\)

Finally subtract the two areas;

A rectangular garden is to be constructed using a rock wall as one side of the garden and wire fencing for the other three sides. Given that there are 30 meters of fencing available, determine the dimensions that would create the garden of maximum area. What is the maximum possible area?

Answers

The dimensions of the garden that create the maximum area are 5 meters by 15 meters, and the maximum possible area is 75 square meters

What is measurement?

Measurement is the process of assigning numerical values to physical quantities, such as length, mass, time, temperature, and volume, in order to describe and quantify the properties of objects and phenomena.

Let's assume that the rock wall is the width of the garden and the wire fencing is used for the length and the other two sides. Let's denote the length of the garden as L and the width as W.

Since we have 30 meters of fencing available, the total length of wire fencing used is:

L + 2W = 30 - W

Simplifying this equation, we get:

L = 30 - 3W

The area of the garden is:

A = LW

Substituting the expression for L from the previous equation, we get:

A = W(30 - 3W)

Expanding the expression, we get:

A = 30W - 3W²

To find the maximum area, we need to take the derivative of A with respect to W and set it equal to zero:

dA/dW = 30 - 6W = 0

Solving for W, we get:

W = 5

Substituting this value back into the expression for L, we get:

L = 15

Therefore, the dimensions of the garden that create the maximum area are 5 meters by 15 meters, and the maximum possible area is:

A = 5(15) = 75 square meters

Answers

The dimensions of the box if it is to use the minimum possible amount of metal are,

⇒ 2.714 m, 2.714 m, 1.358 m

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

A container with an open top is to have 10 m³ capacity.

Now,

Let the dimensions are x, y and z.

Since, Volume of box = 10 m³

Hence, We get;

⇒ xyz = 10

⇒ z = 10/xy

Since, A container is open in top.

Hence, The surface area = 2xz + 2yz + xy

Substitute z = 10/xy;

⇒ S.A = 2x (10/xy) + 2y (10/xy) + xy

          = 20/y + 20/x + xy

For minimum metal;

⇒ d (S.A)/ dx = 0

⇒ - 20/x² + y = 0

⇒ y = 20/x²  ..(i)

And, d (S.A) / dy = 0

⇒ - 20/y² + x = 0

⇒ x = 20/y²   ..(ii)

Divide equation (i) and ((ii);

⇒ x = y

Hence, We get;

⇒ xyz = 10

⇒ x³ = 10

⇒ x = 2.714

And, y = 2.714

So, The value of z is,

⇒ z = 10/xy

⇒ z = 10 / 2.714×2.714

⇒ z = 1.358 m
