a. Okay. So we have to make a table for the amount of butterflies to total insects. Let's simplify the ratio. 36:100 simplifies to 9:25. We can use that ratio to make this table. Just multiply 25 by the amount it takes to get to 50 or 100, and multiply by the same amount at the top to find the amount of butterflies. If you do it correctly, your table should be as shown below in the image.
b. On that note, let's solve for the amount of butterflies in the conservatory. There are 450 total of them. Let's divide 450 by 100 to find the amount we will multiply by. 450/100 is 4.5. We will mutliply 36 by that amount to find the total amount of butterflies. 36 * 4.5 is 162. That's it. There are 162 butterflies in the conservatory.
What is the solution for the system of equations?
Use the substitution method to solve.
y=5−3x
5x−4y= −3
Enter your answer in the boxes.
Answers
Once you have an equation in one of these formats, you take the equation and input it into the value of its correspondent of the other equation.
In this case you have y= 5-3x and 5x-4y=-3.
You should have 5x-4(5-3x)=-3.
Note how the first equation is substituted for the y value of the second equation.
Next solve. First distribute, 5x-20+12x=-3. Combine like terms. 17x-20=-3. Separate the variable and constants by adding 20 to both sides.
17x-20+20=-3+20 -> 17x=17. Divide both sides by 17 to get x = 1.
Now we need to find y. Go back to the first equation and input your x value into it and solve. y=5-3(1) -> y=5-3 -> y = 2
You can check your answer by inputting both values into the second equation and solving. 5(1)-4(2)=-3 -> 5-8=-3 -> -3=-3
The answer is (1,2)

In the diagram ,M//N . Identify all of the angles that are congruent to 2
Answers
Answer:
Angles 4, 6 and 8.
Step-by-step explanation:
Let α and β be two angles, these will be congruent angles if they have exactly the same measure, that is, α = β.
A line that cuts two parallels forms congruent angles.
When two intercept lines form 4 angles. Those that are opposite to each other are vertical angles, these are always congruent.
In the diagram you can see that the angles congruent to 2 are: 4, 6 and 8.
Angle 4 is opposite to the angle 2, therefore it is congruent.
Angle 6 has the same measure of angle 2 because the lines m and n are parallel.
Angle 8 is opposite angle 6, so it is congruent to angle 2 which is equal to angle.

You are going to the State Fair and would like to play one carnival game with the hopes of winning a prize. You can only choose one game to play and want to choose strategically so that you increase your chances of winning. Find the probability of winning each game below and explain HOW you found the probability for each game.
With that information, what game you will play? Explain.
Answers
-------------------------------------------------------
Ring Toss: There are 12 white bottles out of 36 bottles. Assuming each bottle is equally likely to land on, the probability of getting a white bottle is 12/36 = 1/3 = 0.333 = 33.3% roughly. Note: this is assuming that each toss lands on a bottle and there are no tosses that miss.
-------------------------------------------------------
Spinner: There are 8 spaces. Of these spaces, there are 3 spaces we want to land on: 1, 2, or 5. So the probability of winning is 3/8 = 0.375 = 37.5%
-------------------------------------------------------
Nine Sided Dice: We want either the value 2 or a number less than 4 (1,2,3). So there are 3 outcomes we want (1,2,3) out of 9 total. The probability of winning is 3/9 = 1/3 = 0.333 = 33.3% roughly which is the same chances of winning as the ring toss
-------------------------------------------------------
-------------------------------------------------------
In summary, the best game to play is the spinner game because this provides the highest probability of winning (which was 37.5%)

A car’s original price was $26,500. Mr. Thomas paid $21,730. What percent discount did Mr. Thomas receive on the car?
Answers
Final answer:
Mr. Thomas received an 18% discount on the car purchased for $21,730 from an original price of $26,500.
Explanation:
Mr. Thomas received a discount on the car he purchased, and we can calculate the percent discount using the original price and the sale price. The formula for percent discount is: Percent Discount = ((Original Price - Sale Price) / Original Price) × 100%. Applying this to the given numbers:
Original Price = $26,500
Sale Price = $21,730
The difference between the original price and the sale price is the discount amount:
Discount Amount = Original Price - Sale Price
Discount Amount = $26,500 - $21,730
Discount Amount = $4,770
Now we use the formula to calculate the percent discount:
Percent Discount = ($4,770 / $26,500) × 100%
Percent Discount = 18%
Therefore, Mr. Thomas received an 18% discount on the car.

Which angle measure in the triangle shown is the largest?
A.)
B.)
C.)
D.) Not Possible
Answers
Therefore, I cannot provide an exact answer, however, I will try to help you with the concept.
For a triangle, the measure of each angle is proportional to the length of its opposite side.
This means that:
1- The largest angle is the angle opposite to the longest side
2- The smallest angle is the angle opposite to the shortest side
Since you are looking for the largest angle, pick the one facing the longest side
Some tips and tricks:
1- In a right angle triangle, we know that the hypotenuse is the longest side, therefore, the largest angle would be the right angle
2- In an obtuse triangle, the largest angle is simply the obtuse angle itself (the one whose measure is greater than 90)
3- In equilateral triangle, all three angles are equal

The volume of oil currently in the cylindrical tank that is 1/4 full is (90/4) cubic feet.
To determine how much oil in cubic feet is currently in the cylindrical tank when the tank is 1/4 full, we use the formula for the volume of a cylinder, V =
2h, where r is the radius and h is the height. In this case, the radius is 3 feet and the height of the oil will be 1/4 of the total height of the tank.
First, calculate the volume of the entire tank:
Vtotal = 2h = 2(10). Plugging in the values we get
Vtotal =
(3)2(10).
Since the tank is 1/4 full, the volume of oil in the tank will be 1/4 of the total volume: Voil = (1/4)Vtotal = (1/4)
(3)2(10) = (9/4)
(10) = (90/4)
.
Therefore, the volume of oil in the tank is (90/4) cubic feet.

The length of the sides of a triangle are three consecutive integers. If the perimeter is 87, find the dimensions of the triangle. Show all work.
Answers
Since they are consecutive, that means they will all measure the same.
Hope this helps! :)
x+1 = midsized side length
x+2 = largest side length
Add up the three sides. Set the sum equal to 87 and then solve for x
(x)+(x+1)+(x+2) = 87
(x+x+x) + (1+2) = 87
3x+3 = 87
3x = 87-3
3x = 84
x = 84/3
x = 28
If x = 28, then
x+1 = 28+1 = 29
x+2 = 28+2 = 30
So the triangle has the three sides: 28, 29, 30
Check: 28+29+30 = 87

What is the area of this figure?

Answers
Given is the irregular hexagon.
We can divide the given figure into two triangles and one rectangle, and then find areas of each, and then add all of them to find the final answer.
We can find the dimensions by counting the blocks on graph. Given two triangles are identical in shape with base (b=7) and height (h=2).
The area of triangle [tex] =\frac{1}{2} bh = \frac{1}{2} (7)(2) = 7 [/tex] squared units.
Area of two triangles = 14 squared units.
Rectangle has length (l) same as base (b) of triangle i.e. l=7 and width (w=4).
Area of rectangle = l × w = 7 × 4 = 28 squared units.
Total area = 14 + 28 = 42 squared units.
So, final answer is 42 squared units.
Answer:
[tex]42[/tex] [tex]units^2[/tex]
Step-by-step explanation:
A simpler and faster way of solving this problem is through Pick's Theorem.
The theorem states that the area of any given shape (Specifically polygons) on a grid is the number of internal points (every point inside the shape) added to the quantity of the number of boundary points (Every point that is exactly on a point of the grid and is a part of the perimeter of the shape) divided by 2. Take this quantity and subtract 1 and it shows like so,
[tex]A=I+\frac{B}{2}-1[/tex].
In this case, we see that there are 36 internal points and 14 boundary points. So in turn, we get
[tex]A=36 + \frac{14}{2}-1\\A=36+7-1\\A=43-1\\A=\boxed{42}[/tex]
Hence giving our desired result of 42 square units.

The mean of the language arts book is higher than the mean of the social studies book, however, there is a lot of variability in the language arts book. This means that the language arts book could actually be lower than the social studies book. It is not likely but it could happen.
The correct choice is, No, because there is a lot of variability in the language arts book data.
What is Mean?Mean of a set of data is defined as the average of all the values. It gives the exact middle point of the data set.
From the given data, it is clear that the mean number of pages of language arts book is greater than that of social studies book.
However, the mean absolute deviation is greater for language arts book and median is lower for language arts book.
This clears the fact that the variability is high for language arts book. So the number of pages could actually be less than that in social studies book.
Hence the correct option is that we cannot say a valid inference because there is a lot of variability in the language arts book data.
