The garden is approximately 5.5 meters long.
1 yard is approximately 0.91 meters (since 1 meter is approximately 1.094 yards). Therefore, 6 yards is approximately 5.5 meters (6 x 0.91).
Proportionality refers to the relationship between two quantities that change together in a consistent manner. In a proportional relationship, when one quantity changes, the other quantity changes in direct proportion to it.
Since 11 meters is approximately 12 yards, we can set up a proportion:
6 yards = x meters
12 yards = 11 meters
Solving for x, we get:
x = (6 yards)(11 meters/12 yards) = 5.5 meters
Rounding to the nearest tenth, we get that the garden is approximately 5.5 meters long.

Answer:
x = 11.0
Step-by-step explanation:
Since this is a right triangle, we can find the measure of x using one of the trigonometric ratios.
If we allow ∠A to represent the reference angle, we see that BC is the opposite side and AB is the hypotenuse. Thus, we can use the sine ratio, which is sin (reference angle) = opposite/hypotenuse.We can plug in everything into the sine ratio and solve for x:sin (27) = BC / AB
sin (27) = 5 / x
x * sin (27) = 5
x = 5 / sin (27)
x = 11.01344632
x = 11.0
Two angles, ∠A and ∠B, are complementary. If sin A = 4/7, what is cos B?
A. 74
B. 47
C. 37
D. √44/7
The Value of cos B is,
⇒ cos B = 0.64
We have to given that;
Two angles, ∠A and ∠B, are complementary.
And, sin A = 4/7
Now, We can simplify as;
sin A = 4/7
A = sin⁻¹ 4/7
A = 39.8°
Since, Two angles, ∠A and ∠B, are complementary.
Hence, We get;
∠A + ∠B = 90°
39.8° + ∠B = 90°
∠B = 90 - 39.8°
∠B = 50.2°
Thus, Value of cos B is,
⇒ cos B = cos 50.2° = 0.64

suppose at a certain college we know 80% of the students like chipotle and 65% of the students like papa john's pizza. moreover, of the students that like chipotle we know 69% like papa john's pizza. suppose we randomly select a student. what is the probability that a student likes papa john's, given they do not like chipotle?
Therefore, the probability that a student likes papa john's given they do not like chipotle is approximately 0.275 or 27.5%.
Bayes' theorem allows us to calculate conditional probabilities, which is the probability of an event occurring given that another event has already occurred. In this case, we want to find the probability that a student likes Papa John's pizza given that they do not like Chipotle.
We start by using the given probabilities to calculate the probability that a student does not like Chipotle, which is the complement of the probability that they do like Chipotle. Then, we calculate the probability that a student likes both Papa John's and Chipotle, and use this to find the probability that a student likes Papa John's given that they do not like Chipotle.
Bayes' theorem is a powerful tool that is used in a wide range of fields, including statistics, probability theory, and machine learning. It provides a systematic way to update probabilities based on new information or evidence, which is a crucial aspect of many real-world applications.
P(B) = 1 - 0.8 = 0.2 (the probability that a student does not like chipotle)
P(A|B) = P(A and B) / P(B) = (0.65 - 0.69*0.8) / 0.2 ≈ 0.275

Determine the missing dimension of the area is 112 in.²
The missing dimension of the rectangle is 8 inches.
To determine the missing dimension of an area of 112 in.², we need to know at least one of the dimensions. Let's assume we know the length of the rectangle is 14 inches.
We can then use the formula for the area of a rectangle, which is length multiplied by width, to solve for the missing dimension.
We can rearrange the formula to solve for the width by dividing both sides by the length: width = area/length. Plugging in the values we know, we get: width = 112 in.² / 14 in. = 8 inches.
It's important to note that if we had started with the width instead of the length, we would have used the same formula but rearranged it to solve for the length instead. The formula for the area of a rectangle is very useful for solving these types of problems.

one way of solving systems of linear equations is by adding a multiple of one equation to the other. the multiplier for one equation is chosen so that one of the two variables will cancel out in the sum. what should you multiply the equation y
To eliminate one of the variables by adding a multiple of one equation to the other, you should multiply the equation containing the variable you want to eliminate by a suitable multiplier.
Let's assume you want to eliminate the variable y. In this case, you should multiply the equation containing y by a multiplier that will make the coefficient of y in one equation equal to the negative coefficient of y in the other equation. This will ensure that when you add the two equations, the y terms will cancel out.
For example, if the equation you want to eliminate y from is 2x + 3y = 7, and the other equation is 4x + 5y = 9, you would multiply the first equation by -5 and the second equation by 3 to obtain:
-5(2x + 3y) = -5(7) (equation 1 multiplied by -5)
3(4x + 5y) = 3(9) (equation 2 multiplied by 3)
This will result in:
-10x - 15y = -35 (equation 1 after multiplication)
12x + 15y = 27 (equation 2 after multiplication)
Now, when you add the two equations, the y terms will cancel out, and you can solve for the remaining variable x.

paperback books cost a total of $. How much change will Prakash get if he buys 3 hardcover books and 5 paperback books, and gives the clerk $20 bills?
If the cost of one paperback book is less than $1, he would receive even more change.
To solve this problem, we need to know the cost of one paperback book. Unfortunately, that information is missing from the question. Without it, we cannot determine the total cost of the 5 paperback books and therefore cannot calculate Prakash's change.
However, we can make an educated guess based on the fact that the question mentions both paperback and hardcover books. Typically, hardcover books are more expensive than paperbacks, so we can assume that the cost of one paperback book is less than the cost of one hardcover book.
Assuming that each hardcover book costs $10, the total cost of 3 hardcover books would be $30. If Prakash gives the clerk $20 bills, he would pay $60 in total. If we subtract the cost of the 3 hardcover books ($30) from the total amount paid ($60), we are left with $30.
This is the maximum amount of change Prakash could receive if each paperback book costs $1.

The region inside the circle
(x +3)^2 + y^2 = 9
and outside the circle
x^2 + y^2 = 9
The area of the region is (27π/4) square units.
We have,
To find the area of the region inside the circle (x + 3)² + y² = 9 and outside the circle x² + y² = 9, we can use a double integral in polar coordinates.
The region is an annulus (a region between two concentric circles) with the smaller circle centered at (-3,0) and radius 3, and the larger circle centered at the origin and radius 3.
We can rewrite the equations of the circles in polar coordinates as:
(x + 3)² + y² = 9
And,
r² + 2r cos(theta) + 9 = 9
r² + 2r cos(theta) = 0
r = -2 cos(theta)
And,
x² + y² = 9
r² = 9
The region can be described as 0 ≤ r ≤ 3 and -π/2 ≤ θ ≤ π/2 since we are only interested in the part of the region above the x-axis.
The area of the region can be calculated using the following double integral:
A = ∫∫R r dr dθ
where R is the region in polar coordinates.
We can integrate with respect to r first:
A = ∫(-π/2)^(π/2) ∫0³ r dr dθ
= ∫(-π/2)^(π/2) [(1/2) r²]_0³ dθ
= ∫(-π/2)^(π/2) (9/2) dθ
= (9/2) [θ]_(-π/2)^(π/2)
= (9/2) [π - (-π/2)]
= (9/2) (3π/2)
= (27π/4)

let $s$ be a subset of $\{1,2,3,...,50\}$ such that no pair of distinct elements in $s$ has a sum divisible by $7$. what is the maximum number of elements in $s$?
The maximum number of elements in $s$ is $\boxed{7}$, which we can achieve by choosing one element from each of the residue classes modulo $7$.
To find the maximum number of elements in $s$, we need to consider the elements of $\{1,2,3,...,50\}$ that are congruent to each residue class modulo $7$. There are seven residue classes modulo $7$, namely $\{0,1,2,3,4,5,6\}$. Since the sum of two elements from the same residue class modulo $7$ will also be in the same residue class modulo $7$, we cannot include more than one element from each residue class in $s$.
We can include one element from the residue class $0$, which gives us one element. For the other six residue classes, we can choose at most one element from each of them without violating the condition that no pair of distinct elements in $s$ has a sum divisible by $7$. This gives us a total of $1+6=7$ elements in $s$.
Therefore, the maximum number of elements in $s$ is $\boxed{7}$, which we can achieve by choosing one element from each of the residue classes modulo $7$.

a) Define the cardinality of the complement of set
b) Workout the percentage of pupils who
i) Do both jog and cycle
ii) Swim or cycle
iii) Do not swim
iv) Do not jog, swim and cycle
Step-by-step explanation:
a) The complement of the set of pupils who do not jog or swim or cycle would be the set of pupils who do at least one of these activities.
b) We can use a Venn diagram to help us visualize the information given and answer the questions:
```

```
- i) To find the percentage of pupils who do both jog and cycle, we look at the intersection of sets A and B, which is 8%. Therefore, 8% of pupils do both jog and cycle.
- ii) To find the percentage of pupils who swim or cycle, we add the percentages of sets B, C, and D (the parts of the circles that include swimming or cycling), which gives 8% + 15% + 18% = 41%. Therefore, 41% of pupils swim or cycle.
- iii) To find the percentage of pupils who do not swim, we add the percentages of sets A, B, and D (the parts of the circles that do not include swimming), which gives 15% + 8% + 18% = 41%. Therefore, 41% of pupils do not swim.
- iv) To find the percentage of pupils who do not jog, swim, or cycle, we look at the complement of the set of pupils who do at least one of these activities. This is given as 15%, so the percentage of pupils who do not jog, swim, or cycle is 15%.
15% of pupils do not jog, swim or cycle. Of the remaining pupils, 19% both jog and cycle, 61% either swim or cycle, and 39% do not swim. The numbers are based on a full 100% participation rate in regards to these three activities only.
Explanation:The cardinality of a complement of a set refers to the elements that are not in the original set. In context of this question, the complement of the set would be the 15% of pupils who do not partake in jogging, swimming or cycling.
To answer the other parts of the question:
The percentage of pupils who both jog and cycle can be found by adding the percentages of pupils who take part in two or more activities (42%) and then subtracting the percentage of pupils who swim and cycle but do not jog (15%) as well as those who do all three activities (8%). This gives 42% - 15% - 8% = 19%. The percentage of pupils who swim or cycle can be found by adding the percentage of those who swim only (20%), cycle only (18%), do all three activities (8%), as well as those who swim and cycle but do not jog (15%). This gives 20% + 18% + 8% + 15% = 61%. The percentage of pupils who do not swim can be found by subtracting the percentage of those who swim from 100%. This gives 100% - 61% = 39%.The percentage of pupils who do not jog, swim, or cycle is given directly as 15%.Please note that this solution is assuming that all pupils participate in at least one of these activities or none at all and that there are no other activities available.

Answer: How many distinct license plates can be formed if the first number cannot be zero and the three letters cannot form "DOG"?
Step-by-step explanation:
Since the first digit cannot be 0, there are 9 choices for the first digit.
For the three letters, there are 26 choices for the first letter, 26 choices for the second letter, and 25 choices for the third letter (since we cannot use "D", "O", or "G").
For the last three digits, there are 10 choices for each digit.
Therefore, the total number of distinct license plates can be formed is:
9 x 26 x 26 x 25 x 10 x 10 x 10 = 16,290,000
So there are 16,290,000 distinct license plates that can be formed if the first number cannot be zero and the three letters cannot form "DOG".

4. a) Verify that DEF is a right triangle.
E(-2, 2)
D(1,4)
F(3,1)
b) Describe another method that you could
use to answer part a).
Answer:To verify whether triangle DEF is a right triangle, we can use the slope formula and the perpendicularity criterion.
a) Verification of DEF as a right triangle:
Calculate the slopes of the two sides:
Slope of DE = (y2 - y1) / (x2 - x1) = (4 - 2) / (1 - (-2)) = 2 / 3
Slope of EF = (y2 - y1) / (x2 - x1) = (1 - 2) / (3 - (-2)) = -1 / 5
Check if the product of the slopes is -1 (perpendicular lines):
(Slope of DE) * (Slope of EF) = (2 / 3) * (-1 / 5) = -2 / 15
Since the product of the slopes is not -1, the sides DE and EF are not perpendicular. Therefore, triangle DEF is not a right triangle.
b) Another method to determine if triangle DEF is a right triangle:
Another method to answer part a) is by calculating the lengths of the three sides DE, EF, and DF. Then, we can check if the Pythagorean theorem holds true.
Calculate the lengths of the sides:
Length of DE = sqrt((x2 - x1)^2 + (y2 - y1)^2) = sqrt((1 - (-2))^2 + (4 - 2)^2) = sqrt(9 + 4) = sqrt(13)
Length of EF = sqrt((x2 - x1)^2 + (y2 - y1)^2) = sqrt((3 - 1)^2 + (1 - 4)^2) = sqrt(4 + 9) = sqrt(13)
Length of DF = sqrt((x2 - x1)^2 + (y2 - y1)^2) = sqrt((3 - (-2))^2 + (1 - 2)^2) = sqrt(25 + 1) = sqrt(26)
Apply the Pythagorean theorem:
If DF^2 = DE^2 + EF^2, then triangle DEF is a right triangle.
DF^2 = (sqrt(26))^2 = 26
DE^2 + EF^2 = (sqrt(13))^2 + (sqrt(13))^2 = 13 + 13 = 26
Since DF^2 equals DE^2 + EF^2, the Pythagorean theorem holds true, indicating that triangle DEF is a right triangle.
Therefore, the two methods of verification provide conflicting results. One method (using the perpendicularity criterion) suggests that DEF is not a right triangle, while the other method (using the Pythagorean theorem) suggests that it is a right triangle. In such cases, it is important to double-check the calculations and verify the accuracy of the given points to resolve the discrepancy.

Question 18
YARDWORK Each week Imani and Demond must mow their 4-acre yard. When they use both their 36-inch mower and 42-inch mower, it
takes them 2 hours. When the 36-inch mower is out for repairs, it takes them 3 hours. How long would the job take if the 42-inch mower
were broken?
Answer:
6/12
Step-by-step explanation:
this is because if you do the math it is 6/12
Answer all these questions for ratio and rate
1. We can buy 15 cans of green beans for $10.
2. The jet could fly 959 miles in 7 hours at same speed.
3. Its take 4 days for the car manufacturer to produce 800 cars.
How many cans can be bought for $10?A proportion refers to an equation in which two ratios are set equal to each other.
To get how many cans of green beans you can buy for $10, we will set up a proportion:
9 cans / $6 = x cans / $10
By cross-multiplying, we get:
9*($10) = 6x
90 = 6x
x = 90 / 6
x = 15.
2. To get distance the jet can fly in 7 hours, we will use [tex]Distance = rate * time[/tex]
Rate = Distance / Time
Rate = 548 miles / 4 hours
Rate = 137 miles per hour
Now we will it to get how far the jet could fly in 7 hours:
Distance = Rate × Time
Distance = 137 miles per hour × 7 hours
Distance = 959 miles.
3. We will set up a proiportion.
1400 cars / 1 week = 800 cars / x days
To solve for x, we cross-multiply and divide
1400 * x = 800 * 7
1400x = 5600
x = 5600 / 1400
x = 4.
