There are currently 6,210 fish in a lake. If the number of fish in the lake increased by 15 percent during the last year and 20 percent during the year before that, how many more fish are in the lake currently than in the last two years ago?
Answers
I’m pretty sure the answer should be 1,710 if not i’m sorry
Answer:
1710 fish
Step-by-step explanation:
Let the number of fish in the lake last year be 'x'
The equation becomes-
x + 15x/100=6210 (This is because 15% of x is added in x to become
6210... hope you understand)
x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400
Therefore- The number of fish last year = 5400
Now, let the number of fish in the lake 2 years ago be 'y'
The equation becomes-
y + 20y/100 = 5400 (Same logic as last time)
y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500
Therefore- Fish in the lake two years ago = 4500 fish
Difference between current and two years ago = 6210-4500
= 1710 fish
Hope you understood the answer and I hope it helps you :)

Use the diagram of the equilateral triangle shown below to answer the following questions. Show the work that leads to your answers. a. What is the perimeter of the triangle? b. What is the height, ℎ mm, of the equilateral triangle? Write an exact answer using a square root and an approximate answer rounded to the tenths place.
Answers
Answer:
Perimeter is 12mm, height is \(2\sqrt3\)mm in simplest radical form, and 3.5mm in approximate decimal form.
Step-by-step explanation:
The perimeter is easy; since it's an equilateral triangle, all sides are the same length of 4, so you can just do 3*4 (3 sides, 4mm each) to get a perimeter of 12.
For the height, you can see that it forms two right triangles, each with a given base of 2 and a hypotenuse of 4. We can apply the pythagorean theorem (\(a^2+b^2=c^2\)) here to find the missing leg length of the smaller right triangles, which is equal to the big triangle's height.
I've enclosed an attachment for that.

Mario is making dinner for 8 people. Mario buys 6 containers of soup. Each container is 16 ounces. If everyone gets the same amount of soup, how much soup will each person get?
Answers
Answer:
They would get 12oz of soup
Step-by-step explanation:
First, you would do 16x6 because you want to find the total amount of soup you have.
Next, after finding how much you have in total 96oz you then divide by how many people in this case is 8 then you get your answer.
Answer:
Each person gets 12 ounces.
Step-by-step explanation:
If we have 6 containers with 16 ounces in each, in total, we have 96 ounces. (16*6=96)
Now we have to divide the ounces evenly
96/8= 12
Each person gets 12 ounces, to check your work multiply your answer (12) by the amount of people (8) and see if you get you're overall ounces (96)
12*8=96

The table shows the results of 500 experiments. Each experiment involved one person choosing one card from each of two identic decks of cards, labeled 1 through 5. What is the experimental probability of a person choosing a 2, then a 3? Express the answer as percent. ( I really need help with this, I tried looking at my notes and my brain literally can’t function )
Answers
Unfortunately, I cannot see the table you mentioned. However, I can explain how to calculate experimental probability and apply it to the given situation.
Experimental probability is the ratio of the number of times an event occurs to the total number of trials or experiments conducted. In this case, the event is a person choosing a 2, then a 3 from two identical decks of cards labeled 1 through 5.
Let's say we conducted 500 experiments, and in 50 of those experiments, a person chose a 2, then a 3. Then the experimental probability of choosing a 2, then a 3 is:
Experimental probability = (Number of times the event occurred) / (Total number of experiments) = 50 / 500 = 0.1
To express this as a percent, we simply multiply by 100:
Experimental probability as percent = 0.1 x 100% = 10%
Therefore, the experimental probability of a person choosing a 2, then a 3 from two identical decks of cards labeled 1 through 5, based on 500 experiments, is 10%.

Answer: The ratio is 18:3

Step-by-step explanation:
A ratio refers to a fraction. In this case the question asks how many players to coaches there are.
The word "to" means that is where the fraction bar goes.
Players/Coaches
There are 18 players and 3 coaches.
18/3
18 can be divided by 3, 6 times so the fraction can be simplified to
6/1 meaning there are 6 players for every coach.
the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there
Answers
Answer:
Step-by-step explanation:
To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.
Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.
The sum of the parts in the ratio is 8x + 5x + 2x = 15x.
We know that the total number of fruits is 120. Therefore, we can set up the following equation:
15x = 120
To solve for x, we divide both sides of the equation by 15:
x = 120 / 15
x = 8
Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:
Number of bananas = 2x = 2 * 8 = 16
So, there are 16 bananas in total.
We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.
I know I just asked a question i'm sorry but if you could please help me that would mean a lot. Thank you♥♥♥♥

Graph the linear equation,find three points that solve the equation,then plot on the graph. -4y=x-18
Answers
Answer:
Step-by-step explanation:
The equation given to us is:
-4y = x-18
y = (x-18)/-4
Substitute x = 0:
y = (0-18)/-4
y = 4.5
Substitute x = 18
y = (18-18)/-4
y = 0
Substitute x= -18
y = (-18-18)/-4
y = -36/-4
y = 9
The three points found are (0,4.5), (18,0), (-18,9)
Graph all three point onto the coordinate plane.
Join all three point with a line, and extend the line.
