Answers

Answer 1

Answer:

The second company should get the contract.

Question

The project manager for the state department of highways has two beds for the resurfacing of a 10 mile stretch of highway.

Reason

Based on the least expensive price per mile per year, the second company should get the contract. This is because the price per mile per year for the second company is lower than the price per mile per year for the first company.

The first company gives a bit of $120,000 per mile and will guarantee the web for eight years. The second company bids the word for $150,000 per mile using a new asphalt material made from used tires.

The second company will guarantee the work for 12 years. Determine the price per mile per year for each company and decide which company should get the contract based on the least expensive price per mile per year.

The project manager for the state department of highways has two beds for the resurfacing of a 10 mile stretch of highway. The first company gives a bit of $120,000 per mile and will guarantee the web for eight years.

The second company bids the word for $150,000 per mile using a new asphalt material made from used tires. The second company will guarantee the work for 12 years.

Determine the price per mile per year for each company and decide which company should get the contract based on the least expensive price per mile per year

Answer 2
The first company will charge $120,000 per mile for the resurfacing project, and will guarantee the work for 8 years. The second company will charge $150,000 per mile for the project, and will guarantee the work for 12 years.

To determine the price per mile per year for each company, we need to divide the total price by the number of years. For the first company, this would be $120,000 / 8 = $15,000 per mile per year. For the second company, it would be $150,000 / 12 = $12,500 per mile per year.

Based on these calculations, the second company offers the least expensive price per mile per year, at $12,500 per mile per year. Therefore, the project manager should choose the second company to receive the contract.

Answers

The functions f(g(x)) and g(f(x)) are not inverse functions

How to determine if the functions are inverse functions?

From the question, we have the following parameters that can be used in our computation:

f(x) = x³

g(x) = 1/3x

Calculate the composite function f(g(x)).

So, we have

f(g(x)) = (1/3x)³

This gives

f(g(x)) = 1/27x³

Calculate the composite function  g(f(x)).

So, we have

g(f(x)) = 1/3(x³)

You deposit $3000 in an account earning 8% interest compounded monthly. How much will you have in the account in 5 years?

Answers

Answer: $5580

The formula for compound interest is:

A = P(1 + r/n)^nt

where A is the final amount, P is the initial principal (the amount you deposited in the account), r is the annual interest rate (8% in this case), n is the number of times the interest is compounded per year (12 times per year if the interest is compounded monthly), and t is the number of years the money is invested (5 years in this case).

Plugging in the values from the problem, we get:

A = $3000(1 + 0.08/12)^(12*5)

= $3000(1.0067)^60

= $3000*1.86

= $5580

So, after 5 years, you will have $5580 in the account if you deposit $3000 and earn 8% interest compounded monthly.

The value of amount after 5 years is,

⇒ A = $4,380

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;

You deposit $3000 in an account earning 8% interest compounded monthly.

Hence, The value of amount after 5 years is,

⇒ A = 3000 [ 1 + 0.08]⁵

⇒ A = 3000 × 1.08⁵

⇒ A = 3000 × 1.46

⇒ A = $4,380

Answers

Answer:

subtract the equations

Step-by-step explanation:

the second answer option is nonsense.

if the equations really have exactly one solution, then it is impossible to make them equal.

if 2 equations can be made equal, that means they have infinitely many solutions.

the other answers have all some merit.

but the last one (subtract the equations) is the best one.

it means

y = 2x + 4

- y = 3x - 6

------------------

0 = -x + 10

after adding x to both sides we get

x = 10

with that we use any of the 2 basic equations to get y :

y = 2x + 4 = 2×10 + 4 = 24

this worked right away, because the y terms have the same coefficients (1). so, by subtracting one equation from the other we eliminate y as variable and can solve for x.

if that was not the case like in

2y = 4x + 8

y = 3x - 6

we would have to do some transformation or manipulation to bring the system into a form like here in the beginning.

and the first and the third answer option would apply.

Please help im stuck on this problem

Answers

Your friend's rate of change in elevation is 0.5 feet per minute more than your rate.

What is the formula for the rate of change in elevation?To find the height of the building (QR), we can use the angle of elevation formula tan θ=QR/PR.If you're looking for an exact number, use an altimeter, computer, or smartphone to calculate your current position above sea level. If you're trying to find a difference in elevation between 2 points of land, use tie a length of string between two posts and use a level to determine the difference.Let the area of the triangle be xy/2 and dA/dt becomes dA/dt= (xy' +yx')/2. To find y' use the Pythagorean theorem x2 +y2 =z2 where z is constant. So xx' +yy' =0 and y'=-xx'/y and substituting this into dA/dt gives dA/dt =(-x2x'/y +x'y)/2 = x'(y2 -x2)/2y.An angle of elevation is an angle with one horizontal arm, and one arm above horizontal. Usually an angle of elevation is less than or equal to 90°.

Rate of change in elevation = elevation of distance/time

The elevation of 720 feet to an elevation of 750 feet in 30 minutes.

Your rate of change in elevation = 750 - 720 / 30

Your rate of change in elevation = 30 / 30

Your rate of change in elevation = 1 foot per minute

Your friend in-line skates from an elevation of 600 feet to an elevation of 690 feet in one hour.

Your friend's rate of change in elevation = 690 - 600 / 60

Your friend's rate of change in elevation = 90 / 60

Your friend's rate of change in elevation = 1.5 feet per minute

The difference in rate of change in elevation = 1.5 - 1 = 0.5 feet per minute

Thus, your friend's rate of change in elevation is 0.5 feet per minute more than your rate.

The dimensions of the wooden block are 14cm tall, 4cm long and 3 cm wide.

What is prism?

In three dimensional space prism is a polyhedron where two ends are similar.

Given that volume of rectangular prism is 168 cubic centimeters.

And the wooden block is 2x cm tall, (x-4) cm wide and (x-3) cm long.

And also given that a wooden block in a set of building blocks is a rectangular prism.

That means,

Volume of wooden block = Volume of rectangular prism = 168 cm³

Volume of wooden block ;

length × width × height = 168 cm³

Substituting given values in above expression,

2x (x-3) (x-4) = 168 cm³

2x (x²-7x + 12) = 168 cm³

2x³ - 14x²+ 24x = 168 cm³

Simplifying the above equation;

2x³ - 14x²+ 24x- 168 = 0

x³ - 7x²+ 12x- 84 = 0

The factor of above cubic equation is x = 7.

The correlation coefficient is -7.44, which shows a strong negative correlation.

To calculate the correlation coefficient, you can use the following formula:

r = (n Σ(xy) - Σ(x) Σ(y)) / √((n Σ(x²) - (Σ(x))²) (n Σ(y²) - (Σ(y))²))

Where n is the number of data points, x is the variable on the x-axis, y is the variable on the y-axis, Σ(xy) is the sum of the products of x and y, Σ(x) is the sum of x, Σ(y) is the sum of y, Σ(x²) is the sum of the squares of x, and Σ(y²) is the sum of the squares of y.

Plugging in the values from the data, we get:

r = (5 x 198 - 39 x 91) / √((5 x 114 - 39²) x (5 x 187 - 91²))

Simplifying this equation gives us:

r = (-179) / √((-97) x (-6))

r = (-179) / √(582)

r = (-179) / 24.07

r = -7.44

The correlation coefficient is -7.44, which indicates a strong negative correlation. This means that as the value of x increases, the value of y decreases. Conversely, as the value of x decreases, the value of y increases.

juliet has 9 cups of orange syrup. she adds 32 fluid ounces of water to the syrup in order to prepare juice. find the total number of cups in the mixture.

Answers

Juliet will have  13 cups mixture of the orange juice and water .

Given :-

Juliet already has 9 cups of orange juice , and she adds 32 fluid ounces of water into the  cup of orange uice syrup.

So, we have to find that how much cups of syrup does Juliet had ,

So, we know that

1 cup = 8 ounces

but she adds 32 ounces of water which means

= No. of ounces added / no. of ounces in a glass

= 32 / 8

= 4

therefore ,

9 + 4 = 13 glasses.

which means she has 13 glasses of the syrup made up of water and orange juice .

What are the 4 properties of equality?

The four properties of equality addition, subtraction, multiplication, and division can be used to solve an equation. To get the value of an equation's unknown variable, we can easily add, subtract, multiply, or divide the two sides of the equation.

The qualities of equality are those characteristics that have no effect on an equation's truth value, i.e., those characteristics that do not affect the equality of two or more values. These equality-related qualities enable us to define an equivalence relation and solve a number of algebraic equations.

-STATISTICS question!!!-

Answers

Answer:

The data given from the graph proves that Catherine and Ana's suspicions were correct and the athletes at their school do indeed have a quicker reaction time than other students at their school. The average reaction time for the athletes ranges from 240 - 300, while the normal student's reaction time ranges from 260 - 330. There still should be more experiments to test this theory to get more detailed and accurate results because there are still athletes that have the same reaction time as normal students and the dot away from the boxes shows that there is a athlete that has a slower reaction rate than all of the  normal students. So it is safe to say there is indeed a difference in reaction times, but not a drastic one.

Write y=2/3x+7 in standard form using integers.
A. -2x+3y=7
B. -2x+3y=21
C. 3x-2y=21
D. -2x-3y=21

Answers

To write an equation in standard form, you need to rearrange the terms so that the variables are on one side of the equal sign and the constants are on the other side. The standard form of a linear equation is typically written as Ax + By = C, where A and B are constants and x and y are variables.

The given equation y = 2/3x + 7 can be written in standard form by moving all of the terms containing x to the left side of the equal sign and all of the constants to the right side:

2/3x - y = -7

Multiplying both sides of the equation by 3 and simplifying, we get:

3(2/3x - y) = 3(-7)
2x - 3y = -21

Therefore, the equation y = 2/3x + 7 can be written in standard form as -2x - 3y = -21, which corresponds to answer choice (D).

15. Every year in Delaware there is a contest where people create cannons and catapults designed
to launch pumpkins as far in the air as possible. The equation y = 12 + 105x-16x² can be
used to represent the height, y, of a launched pumpkin, where x is the time in seconds that the
pumpkin has been in the air. What is the maximum height that the pumpkin reaches? How
many seconds have passed when the pumpkin hits the ground? (Hint: If the pumpkin hits the
ground, its height is 0 feet.)
(1 point)

Answers

To find the maximum height that the pumpkin reaches, we can set the derivative of the equation equal to 0 and solve for x. The derivative of y = 12 + 105x - 16x^2 is y' = 105 - 32x. Setting y' = 0, we get:

0 = 105 - 32x

32x = 105

x = 105/32

The maximum height is reached when x = 105/32 seconds. To find the maximum height, we can plug this value of x into the original equation:

y = 12 + 105(105/32) - 16(105/32)^2

= 12 + 1053.28125 - 163.28125^2

= 12 + 342.8125 - 106.25

= 248.5625

The maximum height that the pumpkin reaches is 248.5625 feet.

To find the number of seconds it takes for the pumpkin to hit the ground (when its height is 0), we can set y = 0 in the original equation and solve for x:

0 = 12 + 105x - 16x^2

16x^2 - 105x + 12 = 0

(4x - 3)(4x - 4) = 0

The solutions to this equation are x = 3/4 and x = 4/4. The second solution is extraneous, since it represents the time at which the pumpkin was launched (when x=0, y would be 12 feet, not 0 feet). Therefore, the number of seconds it takes for the pumpkin to hit the ground is x = 3/4 seconds.

The equation can be written as - 8x + 12 = 8x + 12 which means it has infinite solutions. So, there are infinite values of [x] for which parameters are equal.

What is Parallelogram? What is triangle?

In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -

∠x + ∠y + ∠z = 180°

There are different types of triangles such as -

equilateral triangle , scalene triangle , isosceles triangle etc.

Given is a square and a triangle as shown.

For equal perimeter -

4(2x + 3) = (2x - 2) + 2(3x + 7)

8x + 12 = 2x - 2 + 6x + 14

8x + 12 = 8x + 12

The equation can be written as -

8x + 12 = 8x + 12

which means it has infinite solutions.

So, there are infinite values of [x] for which parameters are equal.

Therefore, the equation can be written as - 8x + 12 = 8x + 12 which means it has infinite solutions. So, there are infinite values of [x] for which parameters are equal.
