Answer: [tex]A = 28.26 ft^2[/tex]
Step-by-step explanation:
The formula for the area of a circle is: A = π[tex]r^2[/tex]
We need to plug in the values from the question into the formula.
r = 3 feetuse 3.14 for π[tex]A = (3.14)(3)^2[/tex]
A = (3.14)(9)
A = 28.26
Don't forget the units! Since we found the area of the circle, we need to square the units.
[tex]A = 28.26 ft^{2}[/tex]
Last weekend, the movie theater in Wildgrove issued 8,060 tickets to comedies. This weekend, it issued 15,314 tickets to comedies. What is the percent of increase in the number of comedy ticket issued per weekend?
The percent increase in the number of comedy tickets issued per weekend, given the number of tickets issued, can be found to be 90 %
How to find the percentage increase ?To find the percentage increase, you need to find out the increase in the number of tickets issued between last weekend and this weekend. This difference would then be found as a percentage of the number of tickets sold last weekend.
The increase in tickets sold for comedies is therefore:
= This weekend tickets - Last weekend tickets
= 15, 314 - 8, 060
= 7, 254 tickets
The percentage increase is:
= Increase in tickets sold / Total tickets sold last weekend x 100 %
= 7, 254 / 8, 060 x 100 %
= 0. 90 x 100 %
= 90 %

What is a Fraction?A fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator. In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator. In a proper fraction, the numerator is less than the denominator.
Using the rule [tex]y = x + \frac{2}{3}[/tex]
when y = 2
2 = x + 2/3

5x + 3y = 134
x+y = 32
Answer:
(19,13)
x = 19
y = 13
Step-by-step explanation:
5x + 3y = 134
x + y = 32 ⇒ multiply through by -3 -3x -3y = -96 add this to the first equation
5x + 3y = 134
-3x -3y = -96
2x = 38 Divide both sides by 2
x = 19
Substitute 19 for x
x+ y = 32
19 + y = 32
y = 13

Ernie has another account at the bank that pays 2½% simple interest. How
much interest will he earn in 8 years on an initial deposit of $250?
Answer:
$50
Step-by-step explanation:
To find the amount of interest earned in 8 years, we can use the formula:
interest = principal * rate * time
where "principal" is the initial deposit, "rate" is the interest rate, and "time" is the number of years the interest is compounded.
Plugging in the values from the problem, we get:
interest = $250 * 2.5% * 8 years
interest = $250 * 0.025 * 8
interest = $50
So Ernie will earn $50 in interest in 8 years on his initial deposit of $250.

Graph the inequality on the axes below y>-5/4x-2
The graph of the inequality:
y > (-5/4)*x - 2
Can be seen in the image at the end.
How to graph the inequality?Here we want to graph the following inequality:
y > (-5/4)*x - 2
To graph the inequality, we first need to draw the line:
y = (-5/4)*x - 2
With a dashed line (because the points on the line are not solutions) and then shade all the region above that dashed line.
To graph that line you need to find two points on the line and then connect them.
To find the points, we need to evaluate the line in two values of x.
if x = 0.
y = (-5/4)*0 - 2
y = -2
So we have the point (0, -2)
if x = 4
y = (-5/4)*4 - 2
y = -5 - 2
y = -7
So we have the point (4, -7)
Now we can graph the inequality, you can see the image below.

If a success is defined as getting a 6 on a six-sided die, what is P( x < 4) if the dice is rolled 20 times
The probability of rolling a number less than 4 on a six-sided die, when rolled 20 times, is 0.5.
What is probability?Probability is the mathematical study of outcomes in uncertain situations. It is used to describe the likelihood of an event occurring, and it can be expressed as a number between 0 and 1. Probability is used to quantify the uncertainty associated with any given event. It helps us understand how likely it is that something will happen, and it can be used to make predictions about future events. Probability theory is a cornerstone of modern statistics and is widely used in fields such as finance, economics, and science.
This is because there are four possible outcomes when rolling a six-sided die, and two of those outcomes are numbers less than 4: 1 and 2. The probability of rolling a number less than 4 is therefore 2/4, or 0.5. This probability holds true regardless of how many times the die is rolled, as long as it is a fair and unbiased die.

The slope of the line tells us how steep the line is and the direction it is going (positive or negative slope) and the y-intercept is the point at which the line crosses the y-axis.

Q.4. Which of the following substances cannot pass through the cell membranes by simple diffusion? a) Glucose b) Oxygen c) Carbon dioxide d) Water
Answer:
The substance that cannot pass through the cell membranes by simple diffusion is d) Water.
Step-by-step explanation:
Simple diffusion is a type of passive transport that allows substances to move from an area of higher concentration to an area of lower concentration. Small, uncharged molecules, such as oxygen, carbon dioxide, and glucose, can pass through the cell membranes by simple diffusion because they are small enough to fit through the pores in the membrane.
Water, on the other hand, is too large to pass through the pores in the cell membrane by simple diffusion. Instead, it must pass through the membrane by other means, such as osmosis or facilitated diffusion.
Therefore, the substance that cannot pass through the cell membranes by simple diffusion is d) Water.

For the function: y = √(x - 7) - 1
The domain is D: [7, ∞) and the range is R: [1, ∞)
How to find the domain and range of the function?
Remember that the for a function y = f(x), the domain is the set of the possible inputs (possible values of x) while the range is the set of the possible outputs (possible values of y).
Here we want to find the domain and range of the function:
y = √(x - 7) - 1
First, we will find the domain, remember that the argument of a square root must be zero or larger, then the minimum of the domain is the value of x such that:
x - 7 = 0
x = 7
The domain is:
D: [7, ∞)
The square root is an increasing function, then the minimum of the range is given by evaluating the function in the minimum of the domain:
f(7) = √(7 - 7) - 1
f(7) = 1
