Circumference of a circle
Answers
Circumference of a circle with equation \((x+2)^{2}+(y-3)^{2}\) = 9 is 6pi.
To find the circumference of a circle with equation \((x+2)^{2}+(y-3)^{2}\) = 9, we first need to identify its radius, which is the square root of the constant term 9. The radius is therefore 3 units.
The formula for the circumference of a circle is C = 2πr, where C is the circumference, r is the radius, and π is a mathematical constant approximately equal to 3.14159.
Using this formula, we can calculate the circumference of the given circle as:
C = 2πr = 2π(3) = 6π
Therefore, the circumference of the circle with equation \((x+2)^{2}+(y-3)^{2}\) = 9 is 6π units.
It's important to note that the circumference of a circle is the distance around the edge of the circle. It is an important parameter for many applications in geometry, physics, and engineering, among others. Being able to calculate the circumference of a circle given its equation is a fundamental skill in mathematics and is essential for solving many problems in different fields.

Employees of a venue are setting up for a wedding in a hall that has indoor and patio seating. They are trying to decide how to best arrange the flowers. The bride instructed the employees that she wants some of the aisles to have bouquets of only roses and some of the aisles to have bouquets of only dahlias.
For the indoor area, they have decided that in each rose-only aisle, there will be 4 less bouquets of roses than there are roses in each bouquet. There will be 6 rose aisles and one aisle with 2 bouquets of dahlias.
The patio seating area will have one aisle with 4 bouquets of roses and one aisle with 8 bouquets of dahlias.
They plan on using 100 total flowers for the indoor aisles and 132 total flowers for the patio aisles. They want to apply these numbers to determine how many flowers will go in the bouquets if all of the bouquets have an equal number of flowers.

The number of solutions that are viable is; D: There are 2 solutions and only 1 is viable.
How to create a system of equations?For the Rose Only Aisle;
Let the bouquets of roses be X.
Let the number of roses per bouquet be r.
Thus;
Number of bouquets of roses = Xr - 4
Number of rose Aisles = 6
Number of bouquets of dahlias = 2
Patio seating area;
Number of bouquets of roses = 4
Number of bouquet of dahlias (d) = 8
For the rose only aisle, the equation is;

92.4 at 8pm
90 at 9pm
87.6 at 10pm
Answer:
It will be 87.6 at 10pm
Step-by-step explanation:
First, we had to find out how many hours passed between 4pm to 10pm. If we count, we will find that 6 hours passed. Next, multiply 2.4 by 6. This will give us how much the temperature dropped in 6 hours. We can do this because we know it dropped by 2.4 every hour. After you do 2.4*6, you will get the answer 14.4. This is how much the temperature dropped in 6 hours. Next, do 102-14.4. You will get 87.6. This means that the temperature at 10pm will be 87.6.

mote than thtee times the measure of ∠B, and the sum of the measures of the fwo angles is 130
∘
, what is the measure of each angle? m(∠A)= m(∠B)=
Answers
The measure of angle A is 132.5 degrees and the measure of angle B is -5/2 degrees.
To solve this problem, let's represent the measure of angle B as x.
According to the given information, the measure of angle A is 140 degrees more than three times the measure of angle B. So, we can write the equation:
∠A = 3x + 140
The sum of the measures of angle A and angle B is 130 degrees. We can write this as another equation:
∠A + ∠B = 130
Now, substitute the value of ∠A from the first equation into the second equation:
(3x + 140) + x = 130
Combine like terms:
4x + 140 = 130
Subtract 140 from both sides:
4x = -10
Divide both sides by 4:
x = -10/4
Simplify the fraction:
x = -5/2
So, the measure of angle B is -5/2 degrees.
To find the measure of angle A, substitute the value of x into the first equation:
∠A = 3(-5/2) + 140
Multiply:
∠A = -15/2 + 140
Convert -15/2 to a decimal:
∠A = -7.5 + 140
Add:
∠A = 132.5

Which situation best describes a positive correlation? Group of answer choices The height of a candle and the amount of time it stays lit. The price of a pizza and the number of toppings added. The temperature of a cup of hot chocolate and the length of time it sits. The amount of rainfall on Fridays.
Answers
Answer:
The correct option is;
The price of a pizza and the number of toppings added
Step-by-step explanation:
A positive correlation is one in which the variables being correlated, progress in the same direction, such that an increase in one variable will lead o an increase in the other variable;
The price of a pizza depends on the size of the pizza and the price increases for each additional topping added, such that the price of the pizza will increase as the number of toppings is increased
The variable, the height of the candle and the variable, the length of time it stays on, are positively correlated because, the two variables depends on each other whereby the time it takes to completely burn a candle increases as the length of the candle increases, however, the candle can be put out depending on usage, even if it can stay lit for a longer period of time.

At the school carnival, the soccer team sold hamburgers and hot dogs. A person buying one hamburger and one hot dog will spend $17.65. The soccer team sold 22 hamburgers and 39 hot dogs and made $511.55.
Let x be the cost of hamburgers and y be the cost of hot dogs. Then the equation will be
x + y = 17.65 ...1
22x + 39y = 511.55 ...2
Solve the equations, then we have
22(17.65 - y) + 39y = 511.55
388.3 - 22y + 39y = 511.55
17y = 123.25
y = $7.25
Then the value of x will be
x + 7.25 = 17.65
x = 17.65 - 7.25
x = $10.40
The cost of the hamburger and hot dog will be $10.4 and $7.25, respectively. Then the correct option is D.

The function below shows the cost of a large pizza with different numbers of toppings (t). f(t) = 10.25 +1.25t Before tax, Carla paid $19.00 for a large pizza. How many toppings were on Carla's pizza?
A) 6 toppings C) 8 toppings
B) 7 toppings D) 9 toppings
Answers
"The correct answer is B) 7 toppings." The Carla's pizza had 7 toppings.
To find out how many toppings were on Carla's pizza, we need to solve the equation by setting the cost of the pizza equal to the amount Carla paid.
The given function is f(t) = 10.25 + 1.25t, where t represents the number of toppings on the pizza.
Carla paid $19.00 for the pizza.Setting up the equation, we have:
10.25 + 1.25t = 19.00
Subtracting 10.25 from both sides:
1.25t = 8.75
Dividing both sides by 1.25:
t = 7.

Answers
The correct answer is D. $2.75 / $3.24
To determine how much you should expect to pay for gas in Philadelphia versus Cleveland, we need to compare the transportation expenses in both cities. Based on the given data, the transportation expenses are as follows:
Philadelphia: $117
Cleveland: $106
To calculate the expected gas prices, we need to consider the transportation expenses relative to the national average. The formula to find the expected gas price is:
Expected Gas Price = National Average * (Transportation Expense / National Average)
National Average for gas = $2.59
For Philadelphia:
Expected Gas Price in Philadelphia = $2.59 * ($117 / 92) ≈ $3.30
For Cleveland:
Expected Gas Price in Cleveland = $2.59 * ($106 / 78) ≈ $3.51
Comparing the expected gas prices, we find that:
A. $3.03 / $2.75: This option does not match the expected gas prices in Philadelphia and Cleveland.
B. $1.95 / $2.59: This option does not match the expected gas prices in Philadelphia and Cleveland.
C. $2.34 / $2.75: This option does not match the expected gas prices in Philadelphia and Cleveland.

The simplified form of the expression 4(3 - 4x) - 4x + 7 - 8x + 12 - 16x is \(16x^2\) - 52x + 31.
Simplify the given expression, we apply the distributive property first. We multiply 4 with each term inside the parentheses:
4(3 - 4x) - 4x + 7 - 8x + 12 - 16x
This simplifies to:
12 - 16x - 16x + 16x^2 - 4x + 7 - 8x + 12 - 16x
We combine like terms by grouping the variables and constants together:
(-16x - 16x - 4x - 8x - 16x) + (12 + 7 + 12)
This simplifies to:
-52x + 31
Hence, the simplified form of the expression is 16x^2 - 52x + 31. It is a quadratic expression with a coefficient of 16 for the x^2 term.
The -52x term represents the combined coefficient of all the x terms, and the constant term is 31.

Answers
Answer:
Step-by-step explanation:
A nonexperimental research design is a type of research design that lacks manipulation of the independent variable and random assignment.
In other words, the researcher does not intervene or manipulate the independent variable, but instead observes and measures it in its natural setting. Nonexperimental designs are often used in observational studies, surveys, and correlational research.
The absence of manipulation of the independent variable is a key feature of nonexperimental designs. Instead, the researcher typically observes and measures the independent variable in its natural setting, along with the dependent variable. This allows the researcher to examine relationships between variables and draw conclusions about their association, but does not allow for causal inferences.
Nonexperimental research designs are useful for investigating naturally occurring phenomena, exploring relationships between variables, and generating hypotheses for further research. However, they are limited in their ability to establish cause-and-effect relationships due to the lack of manipulation and random assignment.
