The perimeter of a rectangular garden is 372 m
If the width of the garden is 88 m, what is its length?
Answer:
Let L be the length of the rectangular garden. We know that the perimeter of a rectangle is given by: P = 2L + 2W where P is the perimeter, L is the length, and W is the width. In this case, we are given that the perimeter is 372 m and the width is 88 m. Substituting these values into the equation, we get: 372 = 2L + 2(88) Simplifying and solving for L, we get: 372 = 2L + 176 2L = 196 L = 98 Therefore, the length of the rectangular garden is 98 m.
Answer: L = 98 m
Step-by-step explanation:
The perimeter of a rectangle can be found with this formula:
P = 2W + 2L
➜ P is Perimeter
➜ W is Width
➜ L is Length
We will input known values and solve for the length. To solve, we will use multiplication and inverse operations.
372 m = 2(88 m) + 2L
372 m = 176 m + 2L
196 m = 2L
L = 98 m

What are the ordered pair solutions
for this system of equations?
y = -x² + 2
y = x
First, set the equations equal to each other and
move everything to one side.
A:-x²+x+2=0
C:-x² + 2 = x
B:x²+x-2 = 0
D:x²+x+2=0
To find the ordered pair solutions, we need to solve the system of equations by setting them equal to each other:
-x² + x + 2 = x
Simplifying:
-x² + 2x + 2 = 0
We can solve for x using the quadratic formula:
x = (-2 ± sqrt(2^2 - 4(-1)(2))) / (2(-1))
x = (-2 ± sqrt(12)) / (-2)
x = 1 ± sqrt(3)
So the x-values of the ordered pair solutions are:
x = 1 + sqrt(3)
x = 1 - sqrt(3)
To find the corresponding y-values, we can substitute these x-values into either equation. Let's use y = x:
When x = 1 + sqrt(3):
y = 1 + sqrt(3)
When x = 1 - sqrt(3):
y = 1 - sqrt(3)
Set up a proportion and solve for x
Thus value of x in the given the proportion is 7.

The value of cos (90 - x ) = sin (x) = 7/11.
option B.
What is the value of cos (90 - x)?In trigonometry identity, we know that sin(x) = opposite / hypotenuse. Therefore, we can draw a right triangle with an angle x and opposite side 7 and hypotenuse 11.
Using the Pythagorean theorem, we can find the adjacent side of the triangle:
adjacent² = hypotenuse² - opposite²
adjacent² = 11² - 7²
adjacent² = 120
adjacent = √(120)
adjacent = 2 √(30)
Now, we can use the definition of cosine to find cos(90 - x):
cos(90 - x) = sin(x)

Let G := {a1, . . . , an} be a finite abelian group such that n := |G| is odd. Prove that
a1 + · · · + an = 0.
We have shown that the sum of the elements in G is equal to zero, as required.
What is abelian group?An abelian group, also known as a commutative group in mathematics, is a set of elements where the outcome of applying the group operation on two elements of the set does not depend on the order in which the elements are written. The group operation is hence commutative. The integers and real numbers both form abelian groups when addition is used as an operation, and the idea of an abelian group can be seen as a generalisation of these cases.
We can prove this statement using the fact that the sum of the elements in an abelian group is always equal to zero.
Since G is a finite abelian group, every element ai in G has an inverse, denoted by -ai. Furthermore, since G is abelian, the order in which we add the elements does not matter. Therefore, we can rearrange the terms in the sum a1 + a2 + ... + an so that all of the terms are paired with their inverse:
a1 + a2 + ... + an = (a1 + (-a1)) + (a2 + (-a2)) + ... + (an + (-an))
Since n is odd, we have an odd number of elements in G, which means that we have an odd number of pairs of the form ai + (-ai). Therefore, there is exactly one element in the sum that is not paired with its inverse, which is either ai or -ai for some i.
Without loss of generality, suppose that ai is the element that is not paired with its inverse. Then, we have:
a1 + a2 + ... + ai + ... + an = (a1 + (-a1)) + (a2 + (-a2)) + ... + (ai + (-ai)) + ... + (an + (-an))
= 0 + 0 + ... + 0 + ai + (-ai) + ... + 0
= ai - ai
= 0
Therefore, we have shown that the sum of the elements in G is equal to zero, as required.

If you are dealt five cards from a standard deck of 52 cards then find the probability of getting one ten and four kings.
Answer:
The probability of getting one ten from the deck of 52 cards is 4/52, since there are four tens in the deck. After one ten is drawn, there are only 51 cards remaining in the deck.
Step-by-step explanation:
The probability of getting four kings from the remaining 51 cards is (4/51) * (3/50) * (2/49) * (1/48), since there are four kings left in the deck after the ten is drawn, and the probability of drawing a king decreases with each card drawn.
Therefore, the probability of getting one ten and four kings is:
(4/52) * (4/51) * (3/50) * (2/49) * (1/48)
= 0.0000026
This is an extremely low probability, since the chances of getting this specific combination of cards is very low.

If you bet $5 in a Pick 4 lottery game, you either lose $5 or gain $9,995. (The winning prize is $10,000, but your $5 bet is not returned, so the net gain is $9,995.) The game is played by selecting
a four-digit number between 0000 and 9999. What is the probability of winning? If you bet $5 on 1234, what is the expected value of your gain or loss? What is the probability of winning?
Answer:
the expected value of your gain or loss is a net loss of $0.5006.
The probability of winning is 1/10,000 = 0.0001.
Step-by-step explanation:
There are 10,000 possible four-digit numbers between 0000 and 9999. Only one of those numbers is the winning number. Therefore, the probability of winning the Pick 4 game is:
Probability of winning = 1/10,000 = 0.0001
If you bet $5 on 1234, there are two possible outcomes:
-You lose $5 with probability 0.9999
-You gain $9,995 with probability 0.0001
The expected value of your gain or loss is the sum of the products of each outcome and its probability:
Expected value = (-$5 x 0.9999) + ($9,995 x 0.0001)
Expected value = -$0.5006

y = mx + b, where, m - is the slope, b - is the y-interceptUse two points on the line:
(0, 8) and (4, 5)The first point represents the y-intercept, b = 8.
Find the slope, using the slope equation:
m = (y₂ - y₁)/(x₂ - x₁)m = (5 - 8)/(4 - 0) = -3/4Substitute the found values to get the equation of the line:
y = (- 3/4)x + 8Prove the value of the expression (36^5-6^9)(38^9-38^8) is divisible by 30 or 37
Answer:
The given expression is divisible by both 30 and 37
Step-by-step explanation:
First, let's consider the expression (36^5-6^9). We can factor out 6^5 from both terms to get:
(36^5-6^9) = 6^5(6^10-36^3)
Next, let's consider the expression (38^9-38^8). We can factor out 38^8 from both terms to get:
(38^9-38^8) = 38^8(38-1)
Now, we can substitute these factorizations back into the original expression:
(36^5-6^9)(38^9-38^8) = 6^5(6^10-36^3)38^8(38-1)
To show that this expression is divisible by 30, we need to show that it is divisible by both 2 and 3. We can see that 6^5 is divisible by both 2 and 3, so the entire expression is divisible by 2 and 3, and hence divisible by 30.
To show that this expression is divisible by 37, we can use Fermat's Little Theorem, which states that if p is a prime number and a is any integer not divisible by p, then a^(p-1) is congruent to 1 mod p. In this case, p=37 and a=6, so we can write:
6^36 ≡ 1 (mod 37)
Multiplying both sides by 6^10 gives:
6^46 ≡ 6^10 (mod 37)
We can use this congruence to simplify the expression we are interested in:
(36^5-6^9)(38^9-38^8) ≡ (6^10-6^9)(1-38^-1) (mod 37)
Simplifying this expression further gives:
(6^10-6^9)(1-38^-1) ≡ 0 (mod 37)
Therefore, the expression (36^5-6^9)(38^9-38^8) is divisible by both 30 and 37.

What is Probability ?
Probability is a branch of mathematics that deals with the study of random events or outcomes. It is a measure of the likelihood or chance of an event occurring, expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.
If the spinner has 12 sections labeled with the numbers 1 through 12, then the probability of landing on a number greater than 7 would be:
There are 12 equally likely outcomes when the spinner is spun.
Out of these 12 outcomes, 4 are greater than 7: 8, 9, 10, and 11.
Therefore, the probability of landing on a number greater than 7 is 4÷12 or 1÷3, which is approximately 0.333 or 33.3%.
So P(>7) = 1÷3 or 0.333 or 33.3%.

The missing data value in the table of values is y = 14
Determining the missing data valuesWe can use the two given data points (1,6) and (2,10) to find the equation of the linear function that represents the data.
First, we can use the slope formula to find the slope of the line:
slope = (change in y) / (change in x) = (10-6) / (2-1) = 4/1 = 4
Next, we can use the point-slope formula to find the equation of the line using one of the given points. Let's use (1,6):
y - 6 = 4(x - 1)
We can simplify this equation to slope-intercept form (y = mx + b) by solving for y:
y = 4x + 2
Now we can use this equation to find the missing data value when x = 3:
y = 4(3) + 2 = 14

Find the coordinates of the circumcenter of triangle ABC with vertices of A(0,3), B(0,-1), and C(6,1).
Answer:
the circumcenter of triangle ABC is the point (3, 7/3).
Step-by-step explanation:
To find the circumcenter of triangle ABC, we need to find the intersection point of the perpendicular bisectors of its sides.
First, let's find the midpoint and slope of each side of the triangle:
Side AB: midpoint = (0,1), slope = undefined (vertical line)
Side AC: midpoint = (3,2), slope = -1/3
Side BC: midpoint = (3,-1/2), slope = 3/2
Next, we need to find the equations of the perpendicular bisectors of each side. The perpendicular bisector of a segment is the line that passes through its midpoint and is perpendicular to the segment.
Perpendicular bisector of AB: x = 0 (it is a vertical line passing through the midpoint of AB)
Perpendicular bisector of AC: passes through the midpoint (3,2) and has a slope of the negative reciprocal of AC's slope, which is 3
Therefore, the equation of the perpendicular bisector of AC is y - 2 = -1/3 (x - 3), which simplifies to y = -x/3 + 8/3
Perpendicular bisector of BC: passes through the midpoint (3,-1/2) and has a slope of the negative reciprocal of BC's slope, which is -2/3
Therefore, the equation of the perpendicular bisector of BC is y + 1/2 = -2/3 (x - 3), which simplifies to y = -2x/3 + 7/2
Now we need to find the intersection point of any two of these perpendicular bisectors. We can choose any two, but it is usually easier to choose the ones that have equations in slope-intercept form, which are the perpendicular bisectors of AC and BC.
Solving the system of equations y = -x/3 + 8/3 and y = -2x/3 + 7/2, we get x = 3 and y = 7/3.
Therefore, the circumcenter of triangle ABC is the point (3, 7/3).
To make blackberry jam, you must cook blackberries until they become juice. If 4 cups of blackberries give you 1 1/3 cups of juice, find the constant of proportionality of juice to blackberries.
I don't need sleep, I need answers.
The constant of proportionality of juice to blackberries is 3. This means that for every cup of blackberries, you will get 1/3 cup of juice.
Describe Constant of proportionality ?The constant of proportionality is a mathematical term used to describe the relationship between two quantities that are directly proportional to each other. When two quantities are directly proportional, they vary in proportion to each other such that if one quantity doubles, the other also doubles. The constant of proportionality is the number that relates the two quantities together.
To find the constant of proportionality, we need to divide the amount of juice by the amount of blackberries.
Let x be the amount of blackberries required to make 1 cup of juice. Then we have:
4 cups of blackberries = 1 1/3 cups of juice
Divide both sides by 1 1/3 cups of juice:
4 cups of blackberries / (4/3) cups of juice = 3 cups of blackberries / cup of juice
So the constant of proportionality of juice to blackberries is 3. This means that for every cup of blackberries, you will get 1/3 cup of juice.

The outside of a closed glass display case measure 22 inches by 15 inches by 12 inches. The glass is half an inch thick. how much air is contained in the case?k
Answer:
V_air = V_inside = 2,600 cubic inches.
Step-by-step explanation:
To find the amount of air contained in the display case, we need to subtract the volume of the glass from the volume of the outside dimensions.
The volume of the outside dimensions of the display case is:
V_outside = 22 * 15 * 12 = 3,960 cubic inches
The glass is half an inch thick, which means it adds 1 inch to each dimension of the display case. Therefore, the inside dimensions of the display case are:
22 - 2(1) = 20 inches
15 - 2(1) = 13 inches
12 - 2(1) = 10 inches
The volume of the inside dimensions of the display case is:
V_inside = 20 * 13 * 10 = 2,600 cubic inches
The volume of the glass is the difference between the outside and inside volumes:
V_glass = V_outside - V_inside = 3,960 - 2,600 = 1,360 cubic inches
Therefore, the amount of air contained in the display case is:
V_air = V_inside = 2,600 cubic inches.
A student is solving the equation 3(x−12)=9x . Which describes a first step the student could use to solve the equation correctly? Responses The student can distribute 3 on the left side of the equation, resulting in 3x−36=9x . The student can distribute 3 on the left side of the equation, resulting in 3 x − − 36 = 9 x . The student can distribute 3 on the left side of the equation, resulting in 3x−12=9x . The student can distribute 3 on the left side of the equation, resulting in 3 x − − 12 = 9 x . The student can divide both sides of the equation by 3 , resulting in x−12=6x . The student can divide both sides of the equation by 3 , resulting in x − − 12 = 6 x . The student can divide both sides of the equation by 3 , resulting in x−4=3x .
Step-by-step explanation:
The correct first step the student could use to solve the equation 3(x-12)=9x is to distribute 3 on the left side of the equation, resulting in 3x - 36 = 9x.
This is because the distributive property states that a(b + c) = ab + ac. In this case, we have 3(x - 12), so we can distribute the 3 by multiplying it by both terms inside the parentheses: 3(x - 12) = 3x - 36.
Then, we can simplify the equation by subtracting 3x from both sides: -36 = 6x. Finally, we can solve for x by dividing both sides by 6: x = -6.
Therefore, the correct option is: "The student can distribute 3 on the left side of the equation, resulting in 3x−36=9x."
The first step in solving the equation 3(x−12)=9x is to distribute the 3 on the left-hand side of the equation. You multiply each term inside the parentheses by 3, resulting in a simplified equation: 3x - 36 = 9x.
Explanation:If you're aiming to solve the equation 3(x−12)=9x, the initial step would be to distribute the 3 into the parentheses on the left side of the equation. This is achieved by multiplying each term inside the parenthesis by 3. Here's the process in detail:
Step 1: Start with the initial equation, which is 3(x−12)=9x.
Step 2: Remove the parentheses by distributing 3, resulting in 3x - 36 = 9x.
This is a viable initial step because now you have simplified equations on both sides, which helps you to get closer towards isolating the variable x.
