Answer:

1/ y= -3x + 12.96

2/ $9.99 for an entire album & $0.99 for a song

Step-by-step explanation:

We know that the

The amount charged for downloading individual songs = x dollars

And the amount charged for downloading an entire album = y dollars

Let's write a function for person A first

6x + 2y = 25.92

Solve, and we will get

y = -3x + 12.96

Now to person B

4x + 3y = 33.93

Putting the value of y from the first equation in the second

4x + 3(12.96 - 3x) = 33.93

- 5x = - 4.95

x = $0.99

Then we take

y = 12.96 - 3x

= 12.96 - 2.97

= $9.99

The number of oil changes that Will and Owen would each have done is 6 oil changes respectively.

The number of hours it would take both Will and Owen is equal to 4 hours.

In order to write a system of equations to describe this situation, we would assign variables to the number of hours per oil change and number of oil changes respectively, and then translate the word problem into algebraic equation as follows:

Since Will has already finished 4 oil changes today, and can complete more at a rate of 2 oil changes per hour, we have;

y = 2x + 4     .....equation 1.

Since Owen just came on shift, and can finish 3 oil changes every hour, we have;

y = 3x     .....equation 2.

Next, we would determine the number of hours per oil changes they both would have each completed by equating equation 1 and equation 2 as follows;

3x = 2x + 4

3x - 2x = 4

x = 4 hours.

For the number of oil changes for Will, we have;

y = 2(4) + 4

y = 12 oil changes.

For the number of oil changes for Owen, we have;

y = 3(4)

y = 12 oil changes.

Options B, C and D are the situations it is appropriate to use a sample.

Simple random sampling is a sampling technique in which each member of a population has an equal chance of being chosen, through the use of an unbiased selection method.  The sample is chosen by a random method as every subject in the sample is assigned a number.

Sampling saves money by granting researchers to gather the same answers from a sample that they would receive from the population. Non-random sampling is significantly cheaper than random sampling because it lowers the cost associated with searching people and collecting data from them.

Therefore, options B, C and D are the situations it is appropriate to use a sample.

Step-by-step explanation:

The speed of the cyclist in miles per hour is 16 miles per hour

The speed of an object is the rate of change of the object's distance over time

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

A cyclist rides 8 miles in 30 minutes.

The parameters in the above statement can be further expressed as

Distance = 8 miles

Time = 30 minutes

This means that the distance is 8 miles and the time taken to cover the distance is 30 minutes

Convert the minutes to hour

So, we have

Time = 0.5 hour

The speed of the cyclist in miles per hour is then calculated as

speed = 8 miles/0.5 hour

Evaluate the quotient

speed = 16 miles/hour

Hence, the cyclist' speed is 16 miles/hour

b) m = -3/2 , b = -2

c) m = not defined , b = none

d) m = 0 , b = -8

e) m = [tex]\frac{2}{3}[/tex] , b = -4

What do you mean by equation of line?

A line equation is an algebraic representation of a set of points that together form a line in a coordinate system. A number of points that together form a line of axes, represented as a set of variables x,y, form an algebraic equation called the line equation.

Slope intercept form of the line is y = mx - b where m is the slope of the line and b is the x-intercept

a) y = 2x + 3

On comparing the equation with y = mx - b, we get m = 2 , b = -3

b) 2y = -3x -4

⇒ y = ( -3x -4 )/2

⇒ y = [tex]\frac{-3x}{2}[/tex] - 2

On comparing the equation with y = mx - b, we get m = -3/2 , b = -2

c) x = -10

⇒ x + 10 =  0

On comparing the equation with y = mx - b, we get m = not defined , b = none

d) y= 8

On comparing the equation with y = mx - b, we get m = 0 , b = -8

e) 3y = 2x + 12

⇒ y = (2x + 12)/3

The required length of the right rectangular prism is 18 in whose volume is 540 cu. in

Having six faces, a rectangular prism is a three-dimensional shape (two at the top and bottom and four are lateral faces). The prism's faces are all rectangular in form. There are three sets of identical faces as a result. A rectangular prism is often referred to as a cuboid because of its form. A rectangular prism may be found in everyday objects like a geometry box, notebooks, diaries, and rooms.

Rectangular prism characteristics

There are two categories into which rectangular prisms can be divided. These are:

A rectangular prism is a prism with rectangular bases. A right rectangular prism is a prism with six rectangle-shaped faces with angles that are all right angles.

Vertices of a rectangular prism = 8

Edges of a rectangular prism = 12

Faces of a rectangular prism= 6 (including bases)

total volume of the prism = 540 cubic inches.

Answer:

Step-by-step explanation:

To estimate the distance across the gorge, Jamal can use the following steps:

First, he can draw a diagram to represent the situation. He can label points Y, X, A, and B on the diagram and draw the lines YX and AB to represent the locations of the tree and the points he marked.

Next, he can use the Pythagorean Theorem to find the distance AC. The theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. In this case, the side AC is the hypotenuse, and the sides YA and YC are the other two sides. Therefore, he can use the theorem to find AC as follows:

AC^2 = YA^2 + YC^2

He knows the values of YA (500ft) and YC (327ft), so he can substitute these values into the equation and solve for AC:

AC^2 = 500^2 + 327^2

AC^2 = 250000 + 107649

AC^2 = 357659

AC = √357659

AC ≈ 597.56 ft

Finally, he can use the distance AC to estimate the distance across the gorge. The distance across the gorge is equal to the distance from X to Y, which is equal to the sum of the distances from X to A and A to Y. Therefore, he can estimate the distance across the gorge as follows:

distance across gorge = XA + AY

distance across gorge = AC + YA + YC

distance across gorge = 597.56 ft + 500 ft + 327 ft

distance across gorge ≈ 1424.56 ft

This is Jamal's estimate of the distance across the gorge.

La notación científica es una forma de escribir números muy grandes o muy pequeños de manera más compacta y legible. En la notación científica, se mueve el punto decimal de un número hasta que tenga una sola cifra a la izquierda del punto y luego se multiplica el número resultante por 10 elevado a una potencia de 10.

Por ejemplo, para escribir 621,000 en notación científica, podemos mover el punto decimal tres lugares a la derecha para obtener el número 6.21. Luego, podemos multiplicar este número por 10 elevado a la potencia de 3 (10^3), lo que da 6.21 x 10^3 = 6.21 x 1000 = 621,000.

Entonces, en notación científica, 621,000 se escribe como 6.21 x 10^3.
