3 regular pizzas and 2 small pizzas cost $31.
9 regular pizzas and 8 small pizzas cost $103.
What's the cost of 1 regular pizza?
What's the cost of 1 small pizza?
first of all, lets set up the equation
3x + 2y = 31
9x + 8y = 103
+--------------------
now make them equal
12x + 8y = 124
9x + 8y = 103
+----------------------
x=7
y=5
Find the volume of a region bounded by the functions y = 2x + 6, the y-axis, and the x-axis as it revolves
around the x-axis.
GRAPH !
V=
units3
(round to the nearest tenth)
The bounded region in question is a triangle in the second quadrant. The line y = 2x + 6 has intercepts (0, 6) and (-3, 0), so revolving the triangle about the x-axis forms a cone with height 3 and whose circular base has radius 6. Its volume would then π/3 • 6² • 3 = 36π ≈ 113.1 units³.
But you're probably supposed to use calculus. Using the disk method, the integral for the volume is
[tex]\displaystyle V=\pi\int_{-3}^0 (2x+6)^2\,\mathrm dx[/tex]
[tex]\displaystyle V=\pi\int_{-3}^0(4x^2+24x+36)\,\mathrm dx[/tex]
[tex]V=\pi\left(\dfrac43x^3+12x^2+36x\right)\bigg|_{-3}^0=\boxed{36\pi}[/tex]
as expected.

Which statement(s) most directly apply to capitalism?
1. There is heavy government regulation of industry.
II. Individuals can start some, but not all, kinds of enterprises.
III. The price and availability of goods is determined primarily by the market.
a. I and II
b. ll only
c. I and III
d. Ill only
Answer:
The answer is D, lll only.
Step-by-step explanation:
Just took the test on e d g e!
The statement that most directly applies to capitalism is III only.
Option D is the correct answer.
What is capitalism?It is a system of the economy where means of production and distribution are owned by the private, not the government.
We have,
The economic system of capitalism is characterized by private ownership of the means of production and distribution of goods and services, as well as the profit motive as the driving force behind economic activity.
Based on this definition, statement III most directly applies to capitalism, as it highlights the central role of market forces in determining prices and availability of goods.
On the other hand,
Statement I, which suggests heavy government regulation of the industry, is not a typical feature of capitalism, as it implies a more interventionist approach by the government in the economy.
Capitalism generally favors a more limited role for the government in economic affairs, although some government regulations may still be present.
Statement II, which suggests that individuals can start some, but not all, kinds of enterprises, is also not a defining characteristic of capitalism.
In a capitalist system, individuals are generally free to start any kind of enterprise that they wish, provided they can obtain the necessary resources and meet any legal or regulatory requirements.
Therefore,
The statement that most directly applies to capitalism is III only.

find the answer in simplest form 3/7x2/3
Answer:
7 6/7 or 7.8571429
Step-by-step explanation:
The simplest form of the given expression (3/7) x (2/3) is 2/7.
The expression is given as:
(3/7) x (2/3)
The numerator will be 3 x 2 = 6, and the denominator will be 7 x 3 = 21.
So, the simplified form of (3/7) x (2/3) is 6/21.
However, we can further simplify this fraction by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 3.
Dividing 6 and 21 by 3 gives us 2 and 7 respectively.
Therefore, the simplest form of (3/7) x (2/3) is 2/7.

A survey showed that 70% of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight. If 7 adults are randomly selected, find the probability that exactly 2 of them need correction for their eyesight.
Answer:
0.0250047
Step-by-step explanation:
Given that :
Proportion who need correction glasses = 70%
Number of trials = 7
Probability that exactly 2 needs correction glasses :
Using a binomial probability formula :
P(success) = p = proportion who need glasses = 0.7
P(x =x) = nCr * p^x * (1 - p)^(n - x)
P(x = 2) = 7C2 * 0.7^2 * 0.3^(7 - 2)
P(x = 2) = 7C2 * 0.7^2 * 0.3^5
P(x = 2) = 21 * 0.49 * 0.00243
P(x = 2) = 0.0250047

What is the x -coordinate of the x-intercept of the function 2/3y=−6x+12?
Answer:
y=9x+18
Step-by-step explanation:
to get 9, use the rise over run way. Using that, I got 9/1, which is equivalent to 9. Then you MUST add x after, so then you get 9x. The last number is always the y intercept, or where the line meets the vertical line. That was 18.

Bank teller has 500 bills totalling $8100.00. How many tens and twentys does she have
Answer:
$20 bills = 310, $10 bills = 190
Step-by-step explanation:
To solve this problem, we must make a system of equations
Let x = the number of $20 dollar bills and let y = the number of $10 dollar bills
A $20 bill is 20 dollars and a $10 dollar bill is 10 dollars. The money added together will equal $8100, so an equation for this would be:
20x + 10y = 8100
The number of 20 dollar bills and 10 dollar bills added together will be 500 bills, so that equation would be:
x + y = 500
Now we have our system of equation! To solve this, we will use substitution.
If x + y = 500, then x = 500 - y.
We can substitute this into x in the first equation.
20x + 10y = 8100 will become:
20(500 - y) + 10y = 8100
10000 - 20y + 10y = 8100
10000 - 10y = 8100
We can add 10y to both sides and subtract 8100 from both sides
1900 = 10y
Now divide both sides by 10.
190 = y
There are 190 10 dollar bills.
Plugging this value into the equation, we have:
x + y = 500
x + 190 = 500
Subtract 190 from both sides
x = 310
There are 310 20 dollar bills
