The thing that can be conluded about the diagram is that the ponds are the same length. This is according to the SAS theorem.
What is SAS theorem?According to the SAS theorem, if two sides and the included angle of one triangle equal two sides and the included angle of another, the triangles are congruent.
If all three corresponding sides are equal and all three corresponding angles are equal in measure, two triangles are said to be congruent. If two triangles meet one of the following criteria, they are congruent. All three corresponding side pairs are equal. Two corresponding side pairs and their corresponding angles are equal.

The pair of points (-6, y) and (4,8) lie on a line with a slope of 5/2. Set up and solve for the missing y-value using the slope formula. Show all work to receive credit.
Step-by-step explanation:
Slope = (y2 - y1) / (x2 - x1)
Slope = 5/2
x1 = -6
y1 = y
x2 = 4
y2 = 8
5/2 = (8-y) / (4 - (-6))
5/2 = (8-y) / (4+6)
5/2 = (8-y) / 10
5 x 10 = 2 x (8-y)
50 = 16 - 2y
2y = 16 - 50
2y = -34

9 feet is the same as = 2.74 m
Given
1 ft≈ 0.305 m
To find out 9 feet is the same as how many meters:
To convert a foot measurement to a meter measurement, multiply the length by the conversion ratio.
Since one foot is equal to 0.3048 meters, you can use this simple formula to convert:
meters = feet × 0.3048
= 9 * 0.3048
= 2.7432 m
The length in meters is equal to the feet multiplied by 0.3048.
Hence the answer is the 9 feet is the same as meters = 2.74m.

(3x + 8)°
(5x – 20)°
(5x + 4y)°
Find the value of each variable.
Answer:you have 2 lines that cross.
the left angle formed is equal to 3x + 8
the right angle formed is equal to 5x - 20.
the bottom angle formed is equal to 5x + 4y
since the lines are crossed, the opposite angles to each other are equal.
this means that:
3x + 8 = 5x - 20
solve for x to get x = 14 degrees.
the angle on the left side will be equal to 3(14) + 8 = 50 degrees.
the angle on the right side will be equal to 5(14) - 20 = 50 degrees.
this is at it should be since the angles are equal to each other.
since the sum of the 4 angles formed is equal to 360 degrees, the sum of the remaining 2 angles is equal to 260 degrees.
since those 2 angles are equal, then each one must be equal to 130 degrees.
one of those angles is equal to 5x + 4y.
you get 5x + 4y = 130
since x was already found to be 14, replace x with 14 to get:
5(14) + 4y = 130
solve for y to get y = (130 - 5(14)) / 4 which is equal to 15 degrees.
when x = 14 and y = 15, 5x + 4y = 5(14) + 4(15) = 70 + 60 = 130 which confirms the value of 15 for y is good.
your answers are:
x = 14 degrees
y = 15 degrees
2 of the angles measure 50 degrees each.
2 of the angles measure 130 degrees each.

Check step-by-step explanation.
Step-by-step explanation:1. Form a table for the given equation.In order to form the table, we must take several values of x (any values you want to evaluate) and find it's correspondent y value. This is how you do it:
[tex]y=3x+12[/tex]
[tex]x=0, \\y=3(0)+12\\y=12[/tex]
As you may notice, we are just substituting the x value for the x variable into the equation and calculating y. Do this with several values and form a table (check attached image 1).
[tex]x=1, \\y=3(1)+12\\y=15[/tex]
[tex]x=2, \\y=3(2)+12\\y=18[/tex]
2. Draw the points.Using the calculated points, draw them in the cartesian plane. Remember that "x" means how many spaces you move horizontally, and "y" means vertical spaces.
Check attached image 2.
3. Interpret the information.Let's take point (2, 18) as an example. This point is generated when you substitute the x value of 2, meaning 2 hotdogs and the souvenir hat. Then, the functions gives a result of 18, which would be the cost of those 2 hotdogs in addition to the souvenir hat. Point (0, 12), on the other hand, means that you didn't buy any hotdogs but you still have to pay $12 for the souvenir hat.
Abby and Annie have the same number of coins Abby has sorted her coins into groups of 80 and he has sorted her coins into groups of 75 they each have less than 2000 coins how many coins do they have altogether
Altogether, Abby and Annie have 2,400 coins, using the Lowest Common Multiple of 75 and 80.
What is the lowest common multiple?The lowest common multiple (LCM) of two or more numbers is the common multiple shared by the numbers.
LCM of 75 and 80 can be obtained by multiplying common prime factors of 75 and 80, and then raising them to their respective highest power, i.e. 2^4 × 3^1 × 5^2, which gives 1200.
For instance, 1,200 can be divided by both 75 and 80 evenly without a remainder. And there is no other number less than 2,000 that 75 and 80 can divide evenly without a remainder.
Abby's coins = 1,200
Annie's coins = 1,200
Total coins = 2,400
Abby's 80 coins will have 15 groups (1,200/80)
Annie's 75 coins will have 16 groups (1,200/75)
Thus, using the LCM of 80 and 75, the total number of coins held by Abby and Annie is 2,400.

where the middle-term is just a product of "2 times the square root of the terms on both sides".
so let's start by grouping the terms with a variable, and then adding the last term for the trinomial, keeping in mind the middle-term is just that product.
[tex]x^2+6x+5\implies (x^2+6x) ~~ +5\implies (x^2+6x+\square^2) ~~ +5 \\\\\\ \stackrel{middle-term}{6x}=2(\sqrt{x^2})(\sqrt{\square^2})\implies 6x=2x\square\implies \cfrac{6x}{2x}=\square\implies 3=\square[/tex]
ahhhaaa!!! so our missing term from our group is 3, meaning we need to use 3², however, let's remember, all we're doing is borrowing from our very good friend Mr Zero, 0, so if we add 3², we also have to also subtract 3²

Find a b and c ??????
Answer:
a = 70 degrees
b = 20 degrees
c = 20 degrees
Step-by-step explanation:
First, we can find "c":
angleBCA = 90
angleBCA = angleBCD + c
90 = 70 + c
90 - 70 = c
20 = c
Knowing "c", we can find "a".
angleADC = 90
triangleADC = 180
triangleADC = angleADC + c + a
180 = 90 + 20 + a
180 = 110 + a
180 - 110 = a
70 = a
Knowing "a", we can find "b".
angle BCA = 90
triangleACB = 180
triangleACB = angleBCA + a + b
180 = 90 + 70 + b
180 = 160 + b
180 - 60 = b
20 = b

Step-by-step explanation:
You want to know the area of the rectangle with vertices (-5, 5), (-1, 7), (4, -3), and (0, -5).
Distance formulaThe distance formula can be used to find the lengths of the sides. That formula is ...
d = √((x2 -x1)² +(y2 -y1)²)
The distance between the first two points is ...
d = √((-1 -(-5))² +(7 -5)²) = √(4² +2²) = √20
The distance between the next two points is ...
d = √((4 -(-1))² +(-3 -7)²) = √(5² +(-10)²) = √125
AreaThe area is the product of two adjacent side lengths:
A = LW
A = (√125)·(√20) = √(125·20) = √2500 = 50 . . . . square units
The area of the rectangle is 50 units².
Una barra de fierro tiene 3,5 metros de largo. en un punto de la barra se ubica una marca que dista 125cm de uno de los extremos.¿cuanto dista en dm del otro extremo?
Answer:
El otro extremo dista :
12.5 decímetros
Step-by-step explanation:
1 dm = 1 decímetro = 10 cm
1 m = 1 metros = 10 decímetros = 10 dm
3.5 metros = 3.5 * 10 = 35 decímetros
125 cm = 125/10 = 12.5 decímetros
Entonces:
35 dm - 12.5 dm = 22.5 dm

The purpose of post hoc tests following an Analysis of Variance is to address the question of which groups differ from one another. Option A is correct.
Let us understand the post hoc tests:
Post hoc tests are an essential component of ANOVA. When at least three group means are tested for equality using ANOVA, statistically significant findings suggest that not all of the group means are equal. ANOVA results, on the other hand, do not specify which differences between pairs of means are significant. Use post hoc tests to investigate variations between various group averages while keeping the experiment-wise error rate under control.

Find an equation of the line containing the given pair of points (3,4) and (9,9)
Answer:
y = 5x/6 + 3/2
Step-by-step explanation:
First, find the slope (m):
m=(y2-y1)/(x2-x1)
m=(9-4)/(9-3)
m=5/6
y=mx+b ==> slope-intercept form equation
y = 5x/6 + b==> substitute the value of the slope for m
9 = 5(9)/6 + b ==> substitute a point (x, y) or (9, 9) into the equation
9 = 45/6 + b ==> simplify
(9 = 45/6 + b)*6 ==> multiply the equation by 6 to remove denominators
54 = 45 + 6b ==> simplify
54 - 45 = 45 - 45 + 6b ==> solve for b
9 = 6b
9/6 = 6b/6
b = 3/2
y = 5x/6 + 3/2 ==> plug in b for the slop-intercept equation
