In triangle ABC as per given measurements the measure side length BC is equal to 7.26cm (Rounding to three significant figures).
In triangle ABC,
Measure of angle A = 36 degrees
Measure of angle B = 90 degrees
length of AB = 8.7cm
Use trigonometry to solve for the length of BC.
First, Measure of angle C,
In triangle ABC,
Measure of (Angle A + Angle B + Angle C ) = 180
⇒ 36 + 90 + Measure of angle C = 180
⇒ Measure of angle C = 54 degrees
Now , use the sine function to solve for BC,
sin(C) = opposite side /hypotenuse
Substitute the values we have,
⇒ sin(54) = BC/AB
⇒BC = AB × sin(54)
⇒ BC = 8.7 × 0.834
⇒ BC = 7.2558
Rounding to three significant figures, we get,
BC ≈ 7.26 cm.
Therefore, the measure of length BC in triangle ABC is equal to 7.26cm.

Convert 330 litres per hour into millimeters per minute
330 litres per hour = 5489.64 millimeter³ per minute.
Given that330 litres per hour needs to be converted into millimeters per minute.
Conversion factor: 1 litre =1000 cubic centimeter 1 cubic centimeter =1 millimeter³
∴ 1 litre=1000 millimeter³
∴ 1 litre per hour=1000 millimeter³ per hour
Also, 1 hour = 60 minutes
∴ 1 hour = 60 × 60 seconds = 3600 seconds
∴ 1 second = 1/3600 hours=0.0002778 hours
Thus, 1 litre per hour =1000/3600 millimeter³ per second =0.2778 millimeter³ per second
Therefore, 330 litres per hour = 330 × 0.2778 millimeter³ per second=91.494 millimeter³ per second
Also, 1 minute =60 seconds
∴ 1 minute = 60 × 60 seconds=3600 seconds
∴ 1 second = 1/60 minutes=0.01667 minutes
Thus, 91.494 millimeter³ per second = 91.494/0.01667 millimeter³ per minute = 5489.64 millimeter³ per minute

Out of 18 students who study French, German, or both, 13 study French, 5 study only German
and 6 study both.
Draw a Venn diagram below to show the two sets.
Answer:
In this diagram, "F" represents the set of students who study French, "G" represents the set of students who study German, "F∩G" represents the set of students who study both French and German, "G∩F" represents the same set but the order of the labels has been reversed to emphasize that this is the same set, and the numbers inside the diagram indicate how many students belong to each set.
Based on the given information, 13 students study French, 5 study only German (i.e., not French), and 6 study both French and German. Therefore, the number of students who study French only is 13 - 6 = 7.
Step-by-step explanation:
To arrive at the number of students who study French only, we subtract the number of students who study both French and German (6) from the total number of students who study French (13), which gives us 7. This means that there are 7 students who study French but do not study German.

How much plastic wrap will be needed to completly cover and ice cream cone with the slant height of 4. 25 inches and a diameter of 2 inches
The amount of plastic wrap required to cover the entire cone will be 16.575 square inches.
To calculate how much plastic wrap is required to completely cover an ice cream cone with a slant height of 4.25 inches and a diameter of 2 inches, we must use the surface area of the cone.
Here, the ice cream cone can be visualized as a cone-shaped object with an added circular base.
We must use the following formula to calculate the surface area:
Surface area = πr2 + πrl
Where r is the radius and l is the slant height of the cone.
As we know the diameter of the ice cream cone is 2 inches, and its radius can be calculated by dividing it by
2.r = d/2 = 2/2 = 1 inch.
Substitute the values of r and l in the formula, and then calculate the surface area of the cone.
π = 3.14r = 1 inchl = 4.25 inches
Surface area = πr2 + πrl
= 3.14 × 1² + 3.14 × 1 × 4.25
= 3.14 + 13.435

MODELING REAL LIFE You deposit $5000 in an account earning 7. 5% simple interest per year. How long will it take for the balance of the account to be $6500?
We use the formula I = Prt where I is the interest earned, P is the principal, r is the interest rate per year, and t is the time in years. Substituting the values, we find that it will take 4 years for a $5000 balance to reach $6500 with a 7.5% simple interest rate.
To solve this problem, we can use the formula for simple interest:
I = Prt
Where I is the interest earned, P is the principal (initial amount), r is the interest rate per year (as a decimal), and t is the time in years.
In this case, we know that the principal is $5000, the interest rate is 7.5% or 0.075, and we want to find the time required for the balance to reach $6500.
Substituting these values into the formula, we get:
I = $6500 - $5000 = $1500
P = $5000
r = 0.075
t = ?
Solving for t, we get:
$1500 = $5000 * 0.075 * t
t = $1500 / ($5000 * 0.075)
t = 4
Therefore, it will take 4 years for the balance of the account to be $6500 with a 7.5% simple interest rate.

Complete the story problem so that it can be represented by the equation, and then solve. Aldo and Leola help their teacher, Ms. Krebs, put books on the bookshelves in her classroom. There are 2 times as many nonfiction books as fiction books. There are fiction books. They put the same number of books on each of the 7 bookshelves and put as many as they can on each shelf. Then, they put any remaining books on Ms. Krebs's desk. Aldo and Leola put books on each bookshelf. They put books on Ms. Krebs's desk
Aldo and Leola would put 9 fiction books and 18 nonfiction books on each of the 7 bookshelves, for a total of 189 books on the shelves. They would then put the remaining 7 books on Ms. Krebs's desk.
To represent the problem as an equation, we first need to define some variables. Let's let "f" represent the number of fiction books, and "n" represent the number of nonfiction books. We know from the problem that there are 2 times as many nonfiction books as fiction books, so we can write:
n = 2f
We also know that they put the same number of books on each of the 7 bookshelves and put as many as they can on each shelf. Let's call this number "s". We can then write an equation for the total number of books that can fit on the bookshelves:
7s = f + n
Since n = 2f, we can substitute 2f for n in the equation:
7s = f + 2f
Simplifying, we get:
7s = 3f
Finally, we know that any remaining books are put on Ms. Krebs's desk. Let's call this number "r". We can write an equation for the total number of books:
f + n = 7s + r
Substituting 2f for n, we get:
f + 2f = 7s + r
Simplifying, we get:
3f = 7s + r
Now we can solve for "f":
3f = 7s + r
f = (7s + r) / 3
We don't have enough information to solve for "s" or "r", but we can use this equation to find the number of fiction books. For example, if we know that there are a total of 70 books, we can write:
f + n = 70
f + 2f = 70
3f = 70
f = 23.33
Since we can't have a fractional number of books, we would round down to the nearest whole number and get:
f = 23
We could then use the equation f = (7s + r) / 3 to find the number of books on each shelf, assuming there are no books left over:
23 = (7s + 0) / 3
69 = 7s
s = 9.86
Since we can't have a fractional number of books on a shelf, we would round down to the nearest whole number and get:
s = 9
So Aldo and Leola would put 9 fiction books and 18 nonfiction books on each of the 7 bookshelves, for a total of 189 books on the shelves. They would then put the remaining 7 books on Ms. Krebs's desk.

in how many ways can we seat $8$ people around a table if alice and bob won't sit next to each other? (two seatings are the same if one is a rotation of the other.)
There are a total of 7 ways to seat eight people around a table if Alice and Bob won't sit next to each other. This is because the seating arrangement must be a permutation of the seven people not including Alice and Bob.
We can calculate this by taking the factorial of the number of people not including Alice and Bob, which is seven. Since a factorial is the product of an integer and all the integers below it, we can calculate the factorial of seven by multiplying all the integers from one to seven.
This gives us 7=5040, which is the total number of ways to seat eight people around a table if Alice and Bob won't sit next to each other.

a) The rate of change of the drug's concentration at 50 minutes is 1.7 mg/min.
b) The rate of change of the drug's concentration at 85 minutes is 0.2 mg/min.
c) The drug's concentration is decreasing at 115 minutes.
a) The central difference approach can be used to calculate the rate of medication change after 50 minutes.
f'(x) = (f(x+h) - f(x-h))/2 × h ....(1)
As per the question, we have h = 10 and x = 50
Substitute the values of h = 10 and x = 50 in (1),
f'(40) = (f(50+10) - f(50-10))/2 × 10
f'(40) = (89-55)/20
f'(40) = 1.7 mg/min
b) For the rate of change of concentration at 85 minutes:
Here, f(80) = 111 mg and f(90) = 113.
The concentration at 90 minutes is 113 mg.
Rate of change = (f(90) - f(80)) / h
= (113 - 111) /10
= 2 / 10
= 0.2 mg/min
c) Since the concentration at 120 minutes (68 mg) is lower than the concentration at 110 minutes (103 mg), the drug's concentration is decreasing.
Therefore, the drug's concentration is decreasing at 115 minutes.

Work out how many newts are in the pond
The initial number of newts and toads in the pond were in the ratio 3:4, making the total number of organisms in the pond 7x. Solving for x, we get the initial number of toads and newts in the pond as 108 and 81.
Let's assume that the initial number of newts and toads in the pond were 3x and 4x, respectively. Therefore, the total number of organisms in the pond would be 7x.
When 9 more toads entered the pond, the number of toads became 4x + 9, and the ratio of newts to toads changed to 3:5. This means that the number of newts and toads in the pond increased by a factor of 3/2 and 5/4, respectively. We can set up the following equation to solve for x:
3/2n = 4x + 9
5/4n = 4x + 9
Simplifying these equations, we get:
6x + 18 = 5x + 45
x = 27
So, the initial number of toads in the pond was 4x = 108, and the initial number of newts was 3x = 81.

A rectangle has an area of 717. 8m2. One of the sides is 7. 4m in length. Work out the perimeter of the rectangle
The perimeter of the rectangle is approximately 208.9 meters.
To find the perimeter of the rectangle, we need to know the length of the other side.
Let's use the formula for the area of a rectangle:
area = length x width
We know that the area is 717.8 m^2 and one of the sides (width) is 7.4 m. So we can rearrange the formula to solve for the length:
length = area / width
length = 717.8 / 7.4
length ≈ 97.05 m
Now we have both the length and width of the rectangle, so we can find the perimeter:
perimeter = 2 x (length + width)
perimeter = 2 x (97.05 + 7.4)
perimeter = 2 x 104.45

As per the given average, the solution of the breakeven w/ hidden costs is 62% higher.
Let's assume that the costs associated with running a 315-ticket run are $7,592. This means that on average, each ticket needs to sell for $24.10 (($7,592/315) = $24.10) to break even.
Similarly, if we consider the other two runs, we can calculate the average number of tickets needed to break even per show as follows:
For the 323-ticket run, the average number of tickets needed to break even per show is 65. (($7,784/323) = $24.10)
For the 331-ticket run, the average number of tickets needed to break even per show is 56. (($7,977/331) = $24.10)
Furthermore, we can calculate the break-even occupancy percentage for each run, which is the percentage of tickets that need to be sold to break even. The break-even occupancy for each run is as follows:
For the 331-ticket run,
=> 56/331 = 0.17 or 17%,
=> 1-0.17 = 0.83 or 83%,
=> 0.83/0.17 = 4.88,
=> 4.88 x 100% = 488%,
=> 488% x 0.62 = 303%,
=> 303%/4.88 = 62%

Corey spies a bald eagle in a tall tree. He was able to measure the angle of elevation to the bird from where he stands at 62°. The leaves on the tree make it difficult for Corey to watch the bird, so he moves 10 feet further away from the tree to get a better view. Now his angle of elevation is 56°.
What is the height of the tree? Round your answer to the nearest foot.
pls help
The height of the tree is approximately 76 feet.
What is the angle of elevation?
The angle of elevation is the angle created between the line of sight and the horizontal. The angle created is an angle of elevation if the line of sight is upward from the horizontal line.
We can use tangent to set up the following two equations based on the given angles of elevation:
tan(62°) = h/x
tan(56°) = h/(x+10)
We can rearrange the first equation to solve for "h":
h = x * tan(62°)
tan(56°) = (x * tan(62°)) / (x+10)
We can solve for "x" by multiplying both sides by (x+10) and rearranging:
x = 10 * (tan(62°) - tan(56°)))
Now we can substitute this value for "x" into either of the two equations we set up earlier to find the height of the tree "h". Using the first equation, we get:
h = x * tan(62°) ≈ 76 feet
Therefore, the height of the tree is approximately 76 feet.

Write ^4√11^5 without radicals.
Answer: ^4√11^5 = 11^(5/4)
Step-by-step explanation: When we apply a radical, we are asking what number, when raised to a certain power, gives us the number under the radical. For example, ^4√16 is asking what number, when raised to the fourth power, gives us 16. The answer is 2, since 2^4 = 16.
So, ^4√11^5 is asking what number, when raised to the fourth power, gives us 11^5. We can simplify this expression using the exponent laws:
^4√11^5 = (11^5)^(1/4) = 11^(5/4)
Therefore, the simplified expression for ^4√11^5 is 11^(5/4). This expression does not have any radicals, making it easier to work with and manipulate.

an apple falls from a tree 100 km to the ground. if the acceleration due to gravity is 9,8 m/s² and the mass of the apple is 0,2 gram. what is the potential energy of the apple?
Answer: 196 Joules (J)
Step-by-step explanation:
To calculate the potential energy of the apple, we can use the formula:
Potential Energy = Mass x Gravity x Height
First, let's convert the height from kilometers to meters:
100 km = 100,000 meters
Now, let's convert the mass of the apple from grams to kilograms:
0.2 gram = 0.0002 kilograms
Using these values, we can calculate the potential energy:
Potential Energy = 0.0002 kg x 9.8 m/s^2 x 100,000 m
Potential Energy = 196 Joules (J)
Therefore, the potential energy of the apple is 196 Joules (J).

The solution to the system of equations are (-4, 5), (2, 7), (3, -1), no solution, (-5, 8) and (7, -3)
How to solve system of equation by substitution method?System of equation can be solved using different method such as elimination method, substitution method and graphical method.
Question 1 and 2
See attachment for the graphs, where we have the solutions to be
System 1: (-4, 5)
System 2: (2, 7)
Question 3 and 4
Here, we solve the system of equation by substitution method.
So, we have
2x - 7y = 13
3x + y = 8
Make y the subject in (2)
y = -3x + 8
Let's substitute the value of y in equation (i)
2x - 7(-3x + 8) = 13
2x + 21x - 56 = 13
23x = 13 + 56
23x = 69
Divide both sides by 23
x = 69 / 23
x = 3
Let's find y
y = -3(3) + 8
y = -9 + 8
y = -1
For system (4), we have
x - 3y = 2
2x - 6y = 6
So, we have
x = 2 + 3y
By substitution, we have
2(2 + 3y) - 6y = 6
4 + 6y - 6y = 6
4 = 6
The system has no solution
Question 5 and 6
Here, we have
x + y = 3
x - 3y = -29
By eliminating x, we have
4y = 32
So, we have
y = 8
This means that
x + 8 = 3
x = -5
So, the solution is (-5, 8)
For system 6, we have
3y = 26 - 5x
6x + 7y = 21
So, we have
5x + 3y = 26
6x + 7y = 21
This gives
30x + 18y = 156
30x + 35y = 105
By elimination, we have
17y = -51
y = -3
This means that
6x + 7(-3) = 21
6x = 42
So, we have
x = 7
So, the solution is (7, -3)

Question below!
Answer: Line PQ is parallel to line LM
Step-by-step explanation:
We can check if they are of equal distance apart by checking if the ratios of the given lines are equal...in other words we must check if LP/PN=MQ/QN
We know that triangle PNQ is inscribed inside triangle LNM
Using the information we have we see that side LP is 18 units, PN is 16 units, MQ is 27, and QN is 24. With this information we can write out LP/PN=MQ/QN and see if it's true.
LP= 18, PN= 16, 18/16= 1.125
MQ= 27, QN=24, 27/24= 1.125
therefore, LP/PN=MQ/QN is true. Making line PQ and line LM parallel.
