Answer:
[tex]P(x)=8x-150[/tex]
Step-by-step explanation:
Let
x-----> the number of shirts
we know that
The equation of the cost is equal to
[tex]C(x)=2x+150[/tex]
The equation of the sell is equal to
[tex]S(x)=10x[/tex]
The equation of the profit is equal to
[tex]P(x)=S(x)-C(x)[/tex]
substitute the values

tell whether in the sequence is arithmetic if it is what is the common difference 20,11,2,-7
The sequence 20 , 11 , 2 , -7 is an arithmetic sequence.
The common difference is (20 - 11) = (11 - 2) = (2 - -7) = 9
The common difference is 9.
Yes, the given sequence is arithmetic. The common difference is -9.
Arithmetic sequenceAn arithmetic sequence is a list of numbers in which the difference between any two consecutive terms is always the same. This constant difference is called the common difference.
For the sequence shown:
1st Term: 20
2nd Term: 20 - 9 = 11
3rd Term: 11 - 9 = 2
4th Term: 2 - 9 = -7
In other words, the common difference in the arithmetic sequence is -9.

A bakery has 72 half gallons of milk. It takes 1 2/3 cups of milk to make the cake. Note that 1 cup= 1/8 half gallon= 0.125 half gallon. How many cakes can the bakery make? A. 43 cakesB. 288 cakesC. 345 cakesD. 576 cakes
To determine the number of cakes the bakery can make, the required milk per cake in cups is converted to half gallons and then divided into the total available milk in half gallons. Upon calculation, the bakery can make approximately 345 cakes. Thus, the correct answer to the student's question is option C) 345 cakes.
To solve how many cakes the bakery can make using 72 half gallons of milk and with each cake requiring 1 2/3 cups of milk, we must first convert the cups needed for one cake into half gallons. Since 1 cup equals 0.125 half gallons, 1 2/3 cups is equivalent to 1.6667 * 0.125 half gallons. Now, let's calculate the number of cakes:
1 2/3 cups of milk for one cake = 1.6667 * 0.125 half gallons = 0.2083 half gallons per cake.Total available milk in half gallons = 72.Number of cakes = Total available milk / Milk per cake = 72 / 0.2083.After performing the division, we find that the bakery can make approximately 345 cakes. Therefore, the correct answer is C. 345 cakes.
A rental car company charges a basic fee plus a price per mile. One customer drove 250 and paid 56.50, while another customer drove 400 and paid 79. Write an equation in slope - intercept form for the cost of renting a car. Use your equation to find how much it would cost to drive 325 miles?
Answer:
y = 0.15x+19 and
67.75
Step-by-step explanation:
Let us assume y for total cost and x no of miles.
Then x and y are related by a straight line.
Two points lying on the line are
(250,56.50) and (400,79)
Use two point formula
y-56.50/(79-56.50) = x-250/(400-250)
y-56.50 = 22.5(x-250)/150
y = 22.5x/150 -37.50+56.50
Or y = 0.15x+19
To find out cost for 325 miles:
x=325
y= 0.15(325)+19
= 48.75+19
=67.75
Handsome Jack is buying a pony made of diamonds. The price of the pony is PPP dollars, and Jack also has to pay a 25\%25%25, percent diamond pony tax.
Which of the following expressions could represent how much Jack pays in total for the pony?
Choose 2 answers:
A: P+1/4
B: P + 0.25 P
C: (P + 1/4) P
D : 5/4 P
E: 0.25P
Answer:
B: P + 0.25 P
D : 5/4 P
Step-by-step explanation:
The price is P.
The tax is 25% of P, or 0.25P.
The total price is the price plus the tax,
P + 0.25P = P + 1/4P = 4/4P + 1/4P = 5/4P
A percentage is a number expressed fraction of hundred
The correct options for the expression that represent how much Jack pays in total are;
B: P + 0.25·P
D: (5/4)·P
Reason:
The given parameters are;
Material from which the pony is made = Diamond
Price of the pony = P dollars
Amount Jack has to pay as diamond pony tax = 25%
Required:
The expression that represents how much Jack pays per pony
Solution:
The amount Jack pays, A = The price of the pony + Tax
The amount paid as tax = 25% of P = 0.25·P
∴ A = P + 0.25·P
The total amount Jack pays in total for the pony, A = P + 0.25·P[tex]\therefore A = P + 0.25 \cdot P = P + \dfrac{1}{4} \cdot P = \dfrac{5}{4} \cdot P[/tex]
Therefore; The total amount paid = P + 0.25·P = (5/4)·PThe correct options are; B: P + 0.25·P, and D: (5/4)·P

3 problems based on rational and irrational numbers properties only
The discussion covers rational and irrational numbers' properties, particularly focusing on the absence of the smallest positive rational number and the non-manifold nature of rational numbers.
The properties of rational and irrational numbers are fundamental concepts in mathematics, particularly when studying the real number system. Rational numbers include integers and fractions where the numerator and the denominator are integers (e.g., 2/3), while irrational numbers are those that cannot be expressed as such a simple ratio (e.g., √2 or π). The completeness axiom of the real numbers ensures that every number on the number line has a place, whether rational or irrational. An example of how rational and irrational numbers interact is that a graph of a function defined only on rational numbers could approach but never touch an irrational number, which is illustrated in the claim that there is no smallest positive rational number, akin to how there is no smallest positive real number. This is due to the density of rational numbers—between any two rational numbers, there is another rational number.
Example Problems:
Prove by contradiction there is no smallest positive rational number.Discuss why a graph of a function restricted to rational inputs could approach but not contain an irrational number like √2.Explain why the rational numbers are not a manifold by considering an arbitrarily small neighborhood around √2.Angle Bisector Solve for Y

Eric is having a party. he'll have 3 tables for every 6 guests. complete the table showing the number of tables and the number of guests
The relationship between the number of tables and guests for Eric's party maintains a consistent ratio of 1 table for every 2 guests. By setting up a proportional table, we can see this ratio and calculate the number of tables needed for any given number of guests.
The question involves creating a table to show the relationship between the number of tables and the number of guests at Eric's party. Since we know that there are 3 tables for every 6 guests, we can create a proportional table that maintains this 1:2 ratio (one table for every two guests). For example, if there were 12 guests, you would need 6 tables (because 12 guests divided by the ratio of guests to tables, which is 2, equals 6 tables). Similarly, if there were 18 guests, you would need 9 tables, as 18 divided by 2 equals 9.
Proportional Table for Eric's Party:
6 guests - 3 tables12 guests - 6 tables18 guests - 9 tables24 guests - 12 tables30 guests - 15 tables... and so on.This table can be continued in the same manner as long as you keep the same ratio of 1 table for every 2 guests.

I know that: the first term of the sequence is -2, and the fifth term is -1/8
.
What do you know?
Solution
Here the first term = -2
5th term = -1/8
Now we have to find the common ratio (r)
Fifth term A5 = -1/8
-1/8 = [tex]a_{1} r^{4}[/tex]
Here [tex]a_{1} = -2[/tex]
Plug in [tex]a_{1} = -2[/tex] in the fifth term and find the value of r.
-1/8 = -2[tex]r^{4}[/tex]
r^4 = 1/16
Taking 4th root, we get
r = 1/2
Now let's find the second term.
first term *r = -2 *1/2 = -1
2nd term = first term * 1/2 = -1
3rd term = second term * 1/2 = -1 * 1/2 = -1/2
4th term = 3rd term *r = -1/2 *1/2 = -1/4

A "principal square root" is always...
A: a negative fraction
B: a positive integer
C: a negative integer
D:a positive fraction
Really none of the above.
A principal square root of a real number is a positive real number (or a positive real number times i, if you're up to complex numbers, but let's assume not.) It's not necessarily a positive integer, √2 being the obvious example.
Is √2 a positive fraction? We can write it as √2 / 1 so I suppose it is. It's certainly not a rational number. Even if we grant irrationals as fractions surely √0=0 isn't a positive fraction. So "always" isn't correct.
I'd go with none of the above, but if I had to choose I'd choose D.

Use the 2 dots on the line located at (0,1) and (-3,0).
The slope is the change in Y over the change in X:
Change in Y = 0-1 = -1
Change in X = -3 - 0 = -3
Slope = -1 / -3 = 1/3
They intercept in this case is Y1 which = 1.
