Answer: $7,500

Step-by-step explanation:

8/100 x $7,500

= $600

so we will take and add with original price

$600 + $7,5080

= $8,700

Answer:

For the first one

x= About 32.02

y= About 27.58

z= About 55.16

For the second one

x= 6

y= 12

z= about 16.97

Step-by-step explanation:

Their all really simple

These are special right triangles, a 45, 45, 90 and a 30, 60, 90 triangle. The formla for these triangles are shown in the picture below.

Now for the first one ]

Lets find Z first

Now this is a 45 special right triangle so we know the other side s 39 but the hypotenuse is n\(\sqrt{2}\) (I’m using N becuase x and y is taken) So n is basically 39 (look at the image below) and just solve that. Now for x and y. We know its a 30, special right triangle. We know that 39 here is already the answer for  N\(\sqrt{3}\) so make an equation to find the n and you’ll get 27.58 for y. Now For x, its just doubled the y.

For the second one this is easier

We know that the x is (6) becuase its already in the radical number, now to find the hypotnuse, we double that and get 12. Now we know what y is becuase since the 2nd triangle is a 45/45/90, we know that 12 is y, the hypotnuse is just N\(\sqrt{2}\) and we just plug in the n with 12 and solve it!

Answer:

the equation is f(x)4x+2

if the input is a generic number n, the output will be 4n+2

Step-by-step explanation:

Answer: A right angle is also equal to 90 degrees The sides that include the right angle are perpendicular and the base of the triangle. The third side is called the hypotenuse, which is the longest side of all three sides.

Answer:

B

Step-by-step explanation:

You would have to multiply the prices by how many pizzas were sold. So you would have to 9.99 by 39 since that is the price for the small pizza's, and so on.

STEP-BY-STEP EXPLANATION:-

Given - A city has a 5% sales tax.

To find - Is there a proportional relationship

between the cost of items

before tax and the cost of items after

tax?

PROOF:-

Yes, the cost of items before tax is directly

proportional to the cost of items after tax.

REASON:-

With the increase in the sales tax, there is

increase in the cost of items after tax, therefore,

there is a direct relation between the cost of items

before tax and cost of items after tax

Answer:

The integer that describes the translation from B to B' is (-2,1)

Answer:

c. 2/13

Step-by-step explanation:

The bag starts with 8 red marbles, 4 green marbles, and 2 yellow marbles. Since he draws a red marble from the bag and does not replace it, there will be one less marble.

So now there are 7 red marbles, 4 green marbles, and 2 yellow marbles. Add the number of marbles together and then find the probability of drawing a yellow marble.

7+4+2 = 13

2/13

So the probability of Bill drawing a yellow marble would be 2/13.

Answer:

A.) y=-2x+3

Step-by-step explanation:

from the graph, you can tell that this is a negative graph, therefore you can eliminate C and D. The y-intercept is positive 3, which is why the answer is A.)

Answer:

A. y = -2x +3

Step-by-step explanation:

the equation of a line is y = mx + b

m = the slope of the line

b = the y-intercept

The slope of the line is a negative number because the line is moving downwards on the graph.

The slope of the line is -2.

The line intersects the y-axis at positive 3.

The equation would be y = -2x +3

Answer:

The first one plz brainliest

Step-by-step explanation:

2x + y - 8 =0

- 2x from both sides

Y - 8 = -2x

Then add 8 to both sides

Y = -2x + 8

The second one = -1/2x + 4 when its in slope intercept form

And the third one = y = 2x + 2

So it’s the first equation that ve slope of -2 and y intercept of 8

Answer:

2x + y - 8 =0

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.

19. Distributive property is multiplying everything outside of the parenthesis by everything in them!

Let's do it

2(3x + 4y)

We will multiply 2 by 3x and 2 by 4y

2 × 3x + 2 × 4y = ?

6x + 8y

20. Solving algebraically is using multiplication and division, addition and subtraction!

5h = 25

divide 25 by 5 to find h

h = 25/5

h = 5

2 + c = 12

subtract 2 from both sides

2 + c - 2 = 12 - 2

c = 12 -2

c = 10

3y + 10 = 40

We need to do subtraction and division for this one!

Let's subtract 10 from both sides

3y + 10 -10 = 40 - 10

3y = 30

Divide 30 by 3 to find y

y = 30/3

y = 10

22. To find equivalent ratios, let's simplify them!

To simplify ratios, we need to find the highest common factors

a. 2:6

The highest common factor between 2 and 6 is 2, so let's divide both sides by 2

We get ... 1 : 3

b. The highest common factor between 12 and 30 is 6, so let's divide both sides by 6

We get ... 2 : 5

23. To find how many songs are played during a certain amount of time, all we need to do is multiply 12 (the amount of songs played in 1 hour) by however many hours they say!

This can be expressed like this

a. # of songs = 12 × h

Now let's use this expression to answer the next two parts of this question!

b. to find the "# of songs" played in 24 hours, all we need to do is multiply 12 by 24! 24 will be the "h" in our expression. h is the number of hours

Here's what it looks like using our expression we made

# of songs = 12 ( 24)

Solve using a calculator

# of songs = 288

c. To find how many hours it will take to play 60 songs, we will put it in place of the LEFT SIDE of the equation that says "# of songs"

Let's solve it now!

It looks like this ... 60 = 12h

Let's divide to find the number of hours!

60/12 = h

60/12 = 5

It will take 5 hours to play 60 songs!

Answer:

x=2

Step-by-step explanation:

A graph with a domain of all real numbers means that the x-values can take any real value, which includes all numbers from negative infinity to positive infinity. Let's examine each given graph to see which one has a domain of all real numbers:

The points provided: These points are all isolated points and do not represent a continuous function. They do not have a clear domain, and they are not connected in a specific way to form a graph.

A line through (-4, -1) and (0, -3): This represents a linear equation, but it's a specific line segment rather than a graph with all real numbers as its domain.

A vertical line at x = 2: This is a vertical line passing through the x-coordinate 2. It is not a function because it doesn't pass the vertical line test, but it does have all real numbers as its domain since any x-value can be chosen.

Based on the provided options, the graph with a domain of all real numbers is the vertical line at x = 2.

Answer:

Option d. (also option e depending on which way you want to calculate it)

Step-by-step explanation:

First, I should point out that percentage basically means 'out of one hundred' so 25% means '25 out of one hundred.' The value of the percentage increase = 25% × 865. The new value = 865 + The value of the percentage increase.

______________________________________

More Simple Explanation:

Alright, so this might not be a super 'mathematical' trick or related to this question but it still works. Basically we just have to convert 25% into a decimal which I do by moving the decimal point 2 numbers to the left. (Since we cannot see the decimal point in the percentage we automatically know that it stays at the end of 25 a.k.a 25.0) So now our number becomes 0.25 (we got rid of the percentage symbol). Now we just multiply 865 by 0.25 to get our answer!

______________________________________

More Mathematical Process *Basically the value and random useless stuff to know lol because my math teacher showed me this and I thought I needed to add this*:

1) Calculate the new value of the number increased by percentage of its initial value

The new value =

865 + The value of the percentage increase =

865 + (25% × 865) =

865 + 25% × 865 =

(1 + 25%) × 865 =

(100% + 25%) × 865 =

125% × 865 =

125 ÷ 100 × 865 =

125 × 865 ÷ 100 =

108,125 ÷ 100 =

1,081.25

2) Calculate the actual change (the difference) between the new value and the initial one

The actual change =

The new value - 865 =

1,081.25 - 865 =

216.25

(For positive numbers, the actual change = The value of the percentage increase)

Send him a polite email explaining that, while you completed the assignment on your own (which I am assuming to be true), by stumbling upon the solutions in advance you had a hard time doing anything different. Professors are people--he should recognize his mistake and appreciate that you were forthcoming. Chances are he'll reassign the project or discount its weight toward your grade and just tell people to review it anyway because you need to know the material. The sooner you say something the better though. Indeed, after a while it may look like you were trying to hide it from him.
