The owner of the deli recorded the number of costumers who ordered each of four sandwiches avaliable. If the deli has 50 customers the first hour it is open, predict how many customers will order turkey andwiches?Ham: 160Cheese: 100Turkey: 180Veggie: 60
First, we want to find the probability of having a costumer who choose Turkey sanwich.
In order to find it, we calculate the ratio of turkey sandwiches over the total number of orders.
Turkey sandwiches: 180
Total number of orders: 160 + 100 + 180 + 60 = 500
Ratio = turkey / total
Ratio = 180 / 500 = 0.36
Then, the probability of having a costumer who choose Turkey sanwich is
P(T) = 0.36 = 36%
Secondly, in order to find the 36% of 50, we just multiply 0.36 by 50:

You told your friend that you could eat 7/8 of a large pizza. If you only ate 2/3 of what you said you could eat, what fraction of a large pizza did you eat?
The fraction of the large pizza that you were supposed to eat is 7/8. You could only eat 2/3 of 7/8. Thus, the fraction that you ate would be
(2/3) / (7/8)
If we flip 7/8 such that it becomes 8/7, the division sign would change to multiplication sign. Thus, we have
2/3 * 8/7
= 16/21
The fraction of the large pizza pizza that you ate is 16/21

1) Let's solve this Linear System of equations
y=-5x-13
x+2y=-23
2) Using the method of Substitution on the 2nd equation
x +2(-5x-13) = -23
x -10x -26= -23
-9x -26 =-23 Add 26 to both sides
9x=-23+26
9x = 3
x= 3/9
x= 1/3

y=-5/3 -13
y=-44/3

Define slope intercept form.An intercept in mathematics is a location on the y-axis through which the line's slope passes. It is a place on the y-axis where a straight line or a curve crosses. This is reflected in the equation for a line, which is written as y = mx+ c, where m denotes slope and c denotes the y-intercept. A line's equation written using a single point on the line and the line's slope is referred to as the point-slope form. The slope is the rise over run, or the ratio of the change in the y values over the change in the x values, and the point form is denoted as (x, y).

Ava has $14. She earns $8 each hour she spent babysitting. She now has $78. Write and solve an equation to find the number of hours Chloe spent babysitting
Answer:
8 hours.
Step-by-step explanation:
Hello there! Let's help you with your question here!
To always begin questions, let's start with what we know! So, we know that Ava has a total of $14 and that she earns $8 each hour she spends babysitting and now her new total is $78. Alright! So, what do we have here? Here, we're solving for how much money Ava will earn in total. When being asked to write and solve an equation, we always look for what's known as fixed value and a variable value. And what do this mean?
A fixed value is something that can't really be changed under any circumstances. In the question we have here, we are looking for a number that does not change at all and that would be $14. Why? Because no matter what the new total amount of money being made, she'll always start with $14.
A variable value is something that can be changed based on a quantity. In the question we have here, we are looking for a number that follows up with something that we are unsure of but necessary. In this case, that would be $8 each hour. The reason we use this is because we don't know how many hours Ava's going to work. It can be anything and the total amount of money she earns depends on how many hours she worked.
So, now that we have all of our information, we can start by creating a formula! Let y be the new total amount of money that Ava has and let x be how many hours Ava has spent babysitting. And that would be as such:
[tex]y=8x+14[/tex]
Now that we have our formula, we can now begin to solve. We are looking for how many hours Ava spent babysitting to get her new total value up to $78. We substitute y and then solve for x. It would be as such:
[tex]78=8x+14[/tex]
[tex]64=8x[/tex] - Subtracting 14 from both sides.
[tex]8=x[/tex] - Dividing both sides by 8 to isolate x.
Therefore, in order for Ava to get $78 in total, she would need to spend 8 hours of babysitting, if she started out with $14.
Graph a line with an undefined slope that goes through the point (-14,0)Identify the slope:And the Intercept:Write special equation of the line:
We need to first graph a line that goes through the point (-14, 0).
The chosen line passes through the point (-14,0) and (0, 28).
The slope of a line is given by:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Where m is the slope, (x1,y1) is the first point and (x2,y2) is the second point. Applying these points to the problem:
[tex]m=\frac{28-0}{-0-(-14)}=\frac{28}{14}=2[/tex]The slope of the line is 2.
The intercept of the line is the point at which it crosses the "y" axis. In this case this point is (0,28).
We can write the line in its slope-intercept form, since we already calculated those values. This form is given by:
[tex]y(x)=m\cdot x+b[/tex]Where "m" is the slope and "b" is the intercept, therefore the equation of the line is:

This question does not require an understanding of number theory.
NUMBER THEORY
A rational number is any real number that can be represented as a fraction or an integer. This group of numbers excludes imperfect squares or constants like pi.
THE MATH PART
We can use a bit of logic and algebra to do this.
(2/3) > (3/5)
This means we need to find a number relative to (2/3).
Calculate the distance between (2/3) and (3/5) by finding the least common multiple denominators. Two brackets placed together mean multiplication.The rational number is ( 13 / 20 ).
I could have probably made step 2 easier by subtracting ( 1 / 4 ) of ( 1 / 15 ) from ( 2 / 3 ).

[tex]\implies 0.8:48=1:x[/tex]
[tex]\implies \dfrac{0.8}{48}=\dfrac{1}{x}[/tex]
[tex]\implies 0.8x=48[/tex]
[tex]\implies x=\dfrac{48}{0.8}[/tex]
[tex]\implies x=60[/tex]
Therefore, there were 60 books in the book sale.

Aiyana read 147 pages of the book.She completed 70% of the book.If she has completed 70% of the book, then she still has 30% left to read, as 100% - 70% = 30%.
Let x be the number of pages Aiyana still has to read.
Create equivalent ratios with the given information and defined variable, and solve for x:
[tex]\implies 70\%:147=30\%:x[/tex]
[tex]\implies 0.7:147=0.3:x[/tex]
[tex]\implies \dfrac{0.7}{147}=\dfrac{0.3}{x}[/tex]
[tex]\implies 0.7x=44.1[/tex]
[tex]\implies x=\dfrac{44.1}{0.7}[/tex]
[tex]\implies x=63[/tex]
Therefore, Aiyana still has 63 pages left to read.

c = 10.72
hence side c = 10.72 = Opposite
Similarly;
Cos theta = adjacent/Hypotenuse
Cos 47 = 10/d
d = 10/Cos47
d = 10/0.6819
d = 14.66
Hence Side d = 14.66 = Hypotenuse
Side C: Adjacent
Side D: Hypotenuse
Side length of 10 units: Opposite
