This is really hard to explain how to do in words, so I will give you physical movements to perform.
For the first one, draw the graph, then rotate the paper. Redraw the graph on another paper, but draw the triangle where it is on the rotated paper.
For the second, draw the graph, then flip the paper. Place the paper on a light source and trace it on the back.
These strategies are much easier than actually mathing through it, and take much less energy and time.

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.

Which is the correct answer
Answer:
The mode is equal to the minimum
Is the correct answer
Step-by-step explanation:
In this case,
Mean = (52+48+48+54+50)/5
Mean = 50.4
The Median = 50,(the middle value)
Mode = 48 (the value that appears most often)
Now, the minimum value(smallest value) of the data set is 48
so,
The mode is equal to the minimum
Answer: the mode is equal to the minimum

what point below is the solution to the expression 2x+y=12
A) (4,2) C) (8,-1)
B) (3,6) D) (0,6)
Answer:
Step-by-step explanation:
It's B.
Let's rewrite the expression like this :
2x+y=12 ⇒ y=12-2x
and try given values for x :
if x=4 ⇒ y=12-(2×4)=12-8=4 ( so it is not 2 ) ⇒ wrong if x=3 ⇒ y=12-(2×3)=12-6=6 (it is 6) ⇒ right if x=8 ⇒ y=12-(2×8)=12-16=-4 (so it is not -1) ⇒ wrong if x=0 ⇒ y=12-(2×0)=12-0=12 (so it is not 6) ⇒ wrongFigure A is a scale image of Figure B. What is the value of x?

Algebraic Expression:
Answer:
25m+50
Step-by-step explanation:
Answer: y = 25m +50
Step-by-step explanation: Mark will pay $25 each month plus the initial fee of $50. Plug in the amount of months for m to find out how much he has paid in all.
ex: Mark has been with the gym for 7 months
formula- y = 25 x 7 + 50 > $225

Step-by-step explanation:
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?
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

The height of the dead tree is 16 feet
The direction in which the tree should fall is Northeast, Northwest, Southeast, Southwest.
How to solveFrom the given question, since the ray is straight, AC is parallel to DF
Meanwhile triangles ABC and DEF are right angles,
AB/DE =BC/EF
AB/6 = 8/3
AB= 16 feet.
Thus, the height of the tree is 16 feet.
Since 16 ft> 15ft> 14ft> 13ft> 12ft
Therefore, the direction which the tree is falling is Northeast, Northwest, Southeast, Southwest.
