A game room has three circular targets to play darts with. Target A has a diameter of 14 inches, Target B has a radius of 10 inches, and target C has a circumference of 18π inches.
A. Which target is the largest? Justify your answer using the lengths of the radii of all three targets.
B. What is the circumference, in inches, of target A? Use 3.14 to approximate it.
C. What is the area, in square inches, of target C? Use 3.14 to approximate it.
(A). The largest target is Target B since it has the widest radius. (B). The size of Object A is around 44 inches around. (C). Target C has a surface area of around 254 square inches.
What does the term "circumference" mean?The length of a circle and perhaps other circular geometric object is referred to as its circumference. Anything in a double circular shape that is linear in one dimension is the perimeter.
A). We must contrast the radii of the three objects in order to compare their sizes.
Target A consists of a radius of 7 inches and a width of 14 inches.
The radius of Target B is 10 inches.
Target C has a circumference of 18π inches, so we can use the formula C = 2πr to find its radius:
18π = 2πr
r = 9 inches
Target B is the main market since it has the greatest radius.
B). The circumference of a circle is given by the formula C = 2πr, where r is the radius. For Target A, r = 7 inches, so:
C = 2πr
C = 2π(7)
C ≈ 44 inches (using 3.14 to approximate)
Target A's circumference is therefore around 44 inches.
C). The area of a circle is given by the formula A = πr², where r is the radius. For Target C, we know its circumference is 18π inches, so we can use the formula for circumference to find its radius:
C = 2πr
18π = 2πr
r = 9 inches
Target C's area is as follows because of its 9-inch radius:
A = πr²
A = π(9)²
A ≈ 254 square inches (using 3.14 to approximate)
Target C therefore has a surface area of around 254 square inches.

Determine the length and width of a rectangle if the perimeter is
26 and the length is four more than twice the width
The length and width of the rectangle are 10 and 3, respectively.
Let's use "l" to represent the length of the rectangle and "w" to represent the width. From the problem statement, we've got portions of information:
The perimeter is 26. The formulation for the perimeter of a rectangle is P = 2l + 2w. So we are able to write:
2l + 2w = 26
The length is four extra than twice the width. In equation shape:
l = 2w + four
Now we can use substitution to resolve for the length and width. we will alternative the expression 2w + 4 for l within the first equation:
2(2w + 4) + 2w = 26
Simplifying:
4w + 8 + 2w = 26
6w + 8 = 26
6w = 18
w = 3
So the width of the rectangle is three. To discover the length, we're going to substitute w = 3 into the equation for l:
l = 2w + 4 = 2(3) + 4 = 10
So the length of the rectangle is 10.
Thus, the length and width of the rectangle are 10 and 3, respectively.

31. The equation in slope-intercept form is y = -6x + 9.
What is an equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
26.
y-8 = 3(x+4)
y - 8 = 3x + 12 (distribute the 3)
y = 3x + 12 + 8 (add 8 to both sides)
y = 3x + 20
The equation in slope-intercept form is y = 3x + 20.

A box contains 5 balls numbered 1, 2, . . . , 5. In each trial
we remove one ball without replacement. Let X be the total number
of trials until all odd numbered balls are removed. Find V ar(3X +
2022
The variance of 3X + 2022 is -26.
The variable X in this scenario contains the total number of trials until all odd numbered balls are removed from the box without replacement. In order to find the variance of 3X + 2022, we can use the formula for the variance of a linear transformation: V ar(aX + b) = a^2V ar(X).
In this case, a = 3 and b = 2022, so the formula becomes: V ar(3X + 2022) = 3^2V ar(X) = 9V ar(X).
To find the variance of X, we can use the formula for the variance of a discrete random variable: V ar(X) = E(X^2) - [E(X)]^2.
Since X is the total number of trials until all odd numbered balls are removed, we can find E(X) by calculating the expected value of the number of trials until each odd numbered ball is removed. This can be done using the formula for the expected value of a geometric random variable: E(X) = 1/p, where p is the probability of success.
For the first odd numbered ball, the probability of success is 3/5, so E(X) = 1/(3/5) = 5/3. For the second odd numbered ball, the probability of success is 2/4, so E(X) = 1/(2/4) = 4/2 = 2. For the third odd numbered ball, the probability of success is 1/3, so E(X) = 1/(1/3) = 3/1 = 3.
Therefore, the expected value of X is E(X) = 5/3 + 2 + 3 = 14/3.
To find E(X^2), we can use the formula for the expected value of the square of a geometric random variable: E(X^2) = (2 - p)/p^2.
For the first odd numbered ball, E(X^2) = (2 - 3/5)/(3/5)^2 = (10/5 - 3/5)/(9/25) = 7/5 * 25/9 = 35/9. For the second odd numbered ball, E(X^2) = (2 - 2/4)/(2/4)^2 = (8/4 - 2/4)/(4/16) = 6/4 * 16/4 = 24/4 = 6. For the third odd numbered ball, E(X^2) = (2 - 1/3)/(1/3)^2 = (6/3 - 1/3)/(1/9) = 5/3 * 9/1 = 15.
Therefore, the expected value of X^2 is E(X^2) = 35/9 + 6 + 15 = 170/9.
Now we can find the variance of X: V ar(X) = E(X^2) - [E(X)]^2 = 170/9 - (14/3)^2 = 170/9 - 196/9 = -26/9.
Finally, we can find the variance of 3X + 2022: V ar(3X + 2022) = 9V ar(X) = 9(-26/9) = -26.
Therefore, the variance of 3X + 2022 is -26.

Ranjit made pies for a fundraiser. He cut all the pies into eighths. After the first day of the fundraiser Ranjit sold 10 slices and had 2- of the pies left. Write and solve an equation to determine how many pies Ranjit made for the fundraiser.
If Ranjit made pies for a fundraiser. The number of pies Ranjit made for the fundraiser is: 26.
How to find the number of pies Ranjit?Let p = total number of pies that Ranjit made
Let s = Total number of slices of pie that he made.
Since each pie is cut into 8 slices, we have:
s = 8p
After the first day of the fundraiser, Ranjit sold 10 slices, which means he had s - 10 slices left. Since he had 2 whole pies left, we know that he had 16 slices left. Therefore:
s - 10 = 16
Substituting s = 8p, we get:
8p - 10 = 16
Adding 10 to both sides, we get:
8p = 26
Dividing both sides by 8, we get:
p = 3.25
This means that Ranjit made 3.25 pies for the fundraiser.
The total number of slices would have been:
s = 8p = 8(3.25) = 26
On the first day, he sold 10 slices, which means he had 16 slices left. This matches our initial calculation and confirms that our solution is correct.

Now, let Q(x)=3x^2+5x+10 and consider the input value a=3. We could now write the difference quotient as
(Q(3+h)−Q(3))/h
where h≠0h≠0.
Use this difference quotient to calculate the average rate of change of f(x) from x=3 to x=3+h for the following particular values of h.
When h=0.2, the average rate of change of Q(x) is?
The average rate of change of Q(x) from x=3 to x=3+h for h=0.2 is 21.2.
To find the average rate of change of Q(x) from x=3 to x=3+h, we need to plug in the values of h and a into the difference quotient and simplify.
When h=0.2, the difference quotient becomes:
(Q(3+0.2)−Q(3))/0.2
= (Q(3.2)−Q(3))/0.2
= ((3(3.2)^2+5(3.2)+10)−(3(3)^2+5(3)+10))/0.2
= ((30.24+16+10)−(27+15+10))/0.2

John and Scott are selling cheesecakes for a school fundraiser. customers can buy new york style cheesecake and so apple cheesecake. John sold 7 new york style cheesecakes and 4 apple cheesecake for a total of $116. Scott sold 8 new York style cheesecake and 12 apple cheesecakes for the total of$244. Find the cost of each of one New York style cheesecake and one apple cheesecake.
Let
x
represent the
price of one New York style
cheesecake
and
y
the price of
one apple cheesecake
. Based on the information provided, we can construct two equations:
7x + 4y= 116
8x + 12y = 244
We can
solve
for
x
in terms of
y
using the first equation:
7x= 116-4y\sx= (116-4y) / 7
When we plug this expression into the
second equation
for
x
, we get:
8[(116 - 4y) / 7] + 12y = 244
To
eliminate
the fraction,
multiply both sides by 7
.
8(116 - 4y) + 84y = 1708
Extending the parentheses and combining similar terms yields:
928-32y + 84y= 1708
When we simplify, we get the following:
52y = 780
When we
divide both sides by 52
, we get:
y = 15
We now know that
y = 15
; we can use either of the original equations to solve for x:
7x + 4(15) = 116
7x = 56
x = 8
Therefore, one
New York cheesecake costs $8
, and
one apple cheesecake costs $15
.

If pure water is added to a 15% alcohol solution, what percent alcohol is being added?
If I understand your question correctly, pure water is 0% alcohol, so by adding water, this will dilute your 15% alcohol solution and lower the percentage of alcohol in the solution.
Many word problems are set up like "You have some amount of 15% alcohol solution and you add some pure water. You end up with some other amount of the diluted mixture. How much 15% alcohol solution and how much pure water were mixed."
For those ones, use 0% alcohol for your pure water.

The value for the function f(g(-2)) is obtained as f(g(-2)) = 0.
What is a function?
In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.
The graph for the function y = f(x) is given.
The graph for the function y = g(x) is given.
We need to evaluate the function f(g(-2)).
From the graph of y = g(x) the value for g(-2) is obtained as -
g(-2) = 1
So, now we have -
f(g(-2)) = f(1)
From the graph of y = f(x) the value for f(1) is obtained as -
f(1) = 0
Therefore, the value is obtained as 0.
