Step-by-step explanation:

You need $2500 plus the amount to print the tickets. So 2500+155= $2655.

$155 will break even and then the $2500 will be the profit.

Answer:

The sum of the triangle gives us the Fibonacci sequence. The sequence starts with 0 and 1, then adds along the road, such as 3+5=8, and 5+8=13.

It's a pattern going along while adding sequences together.

i hope this helps, it's not the best, but it works! :)

Answer:

10 1/4

Step-by-step explanation:

okay so the equation 4 3/8-(-5 7/8) needs to be simplified to a answerable equation by changing -(-5 7/8) to + 5 7/8

the reason for this is because when two subtraction signs are like this -(- it turns the number into a positive and we add instead of subtract.

4 3/8 + 5 7/8 = 9 10/8 = 10 2/8 = 10 1/4

I hope this helps you

Man, I have to be honest with you, I have no clue. But here is something else though. I had to take Geometry last year, and you are right. It does suck. But, you will get through it! There is a light at the end of the tunnel and you will get it! Keep up the good work!

Answer:

m<1 = 87

Step-by-step explanation:

Bro I got you! You ain't gotta hate school no more!

Right the equation like this

m<1 + m<2 = <TSV (plug in)

m<1 + 65 = 152 (subtract 65 from 152 to get m<1)

m<1 = 87

There you go!

Hope this helps ya!

Step-by-step explanation:

Answer:

B. The number of vertices equal the number of isosceles triangles.

Step-by-step explanation:

1st figure:

No. of vertices: 4

No. of isosceles triangles: 4

2nd figure:

No. of vertices: 5

No. of isosceles triangles: 5

3rd figure:

No. of vertices: 6

No. of isosceles triangles: 6

Thus, the number of vertices equal to the number of isosceles triangles.

Answer:

The slope-intercept form of the equation of this line is:

[tex]y=-x[/tex]

Hence, option 'c' is true.

Step-by-step explanation:

From the line equation, let us take two points

Finding the slope between two points

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(1,\:-1\right),\:\left(x_2,\:y_2\right)=\left(-1,\:1\right)[/tex]

[tex]m=\frac{1-\left(-1\right)}{-1-1}[/tex]

[tex]m=-1[/tex]

From the line graph, we can determine the y-intercept by setting x=0 and checking the y-value at x=0

at x=0, y=0

Thus, (0, 0) is the y-intercept

We know that the slope-intercept form of the line equation is

y=mx+b

where

As we have already determined m=-1 and y-intercept=b=0

so substituting m=-1, b=0 in the slope-intercept form of the line equation

[tex]y=mx+b[/tex]

[tex]y=(-1)x+0[/tex]

[tex]y=-x[/tex]

Thus, the slope-intercept form of the equation of this line is:

[tex]y=-x[/tex]

Hence, option 'c' is true.

Answer:

3) the vertex is moved to the left 7 units

Step-by-step explanation:

When a number is inside the () and is being added or subtracted it goes to the opposite of the sign if it is + it goes left if it is - it goes right however with linear functions it is + right - left

Answer:

24 pies

Step-by-step explanation:

Let x represent the number of pies and set up an equation:

6x = 3.75x + 54

Solve for x:

6x = 3.75x + 54

2.25x = 54

x = 24

So, Carrie and Joel have to sell 24 pies to break even

Answer:

19.1, rounded= 19

Step-by-step explanation:

115 divided by 6 = 19.1

Answer:

20 tanks

Step-by-step explanation:

Number of tanks = Total fish ÷ Number of fish that a tank can hold

                            = 115 ÷ 6

                             = 19 [tex]\frac{1}{6}[/tex]

                              = 20 tanks

Answer:

4pi

Step-by-step explanation:

Area of a circle is pi (r^2)

Radius is 2, 2 squared is 4, 4 times pi is 4pi.

Answer: The point (5,7) is on the line 5x+6y = 67

=====================================================

Explanation:

(5,7) means x = 5 and y = 7 pair up

Plug in those values to get...

5x + 6y = 67

5*5 + 6*7 = 67

25 + 42 = 67

67 = 67

We get the same number on both sides after fully simplifying. This means the equation is true. A true equation in the last step means the first equation is true when (x,y) = (5,7).

Therefore, the point (5,7) is a solution and it is on the line 5x+6y = 67.

Answer:

The addition expression that represents the situation is;

175 + 100 + 100 - 55 -55

Step-by-step explanation:

Here, we want to write an addition expression to represent the situation

While the deposits are considered positive, the withdrawals are considered negative

So the addition expression will be;

175 + 100 + 100 - 55 - 55

===========================================================

Explanation:

The sequence is not arithmetic because the distance between adjacent terms keeps increasing. For instance, the gap from 0.4 to 1.6 is 1.6-0.4 = 1.2, while the gap from 1.6 to 6.4 is 6.4-1.6 = 4.8. There is no common difference, so we can rule out choices A and B.

To check if we have a geometric sequence, divide each term by its previous term

(term2)/(term1) = (1.6)/(0.4) = 4

(term3)/(term2) = (6.4)/(1.6) = 4

(term4)/(term3) = (25.6)/(6.4) = 4

Each time we get 4 as a result, so this sequence is geometric and the common ratio is r = 4.

Put another way: each new term is found by multiplying the previous term by 4.

0.4*4 = 1.6

1.6*4 = 6.4

6.4*4 = 25.6

This all leads to D being the answer.

Side note: the nth term of this geometric sequence is [tex]a_n = 0.4*(4)^{n-1}[/tex] where n is a positive integer and starts at n = 1.

Answer:

120 mins

Step-by-step explanation:

number of minutes in an hour = 60

number of hours = 2

total number of minutes = 60 x 2 = 120

Answer:

120 minutes

Step-by-step explanation:

an hour is 60 minutes and if you put them in for 2 hours you multiply 2×60 and your answer is 120
