All the given triangles are congruent by SSS, SAS, and AAA rules.
What is congruence?If two figures are exactly the same in sense of their length side all things then they will be congruent.
If it is possible to superimpose one geometric figure on the other so that their entire surface coincides, that geometric figure is said to be congruent or to be in the relation of congruence.
As per the given triangles,
In the first triangle, two sides are the same and the third side is the common side thus it will be congruent with the SSS rule.
The remaining triangles are also congruent similarly to SAS and AAA rules like this.
Hence "By the SSS, SAS, and AAA criteria, every triangle in the example is congruent.".

BOOKS Eduardo is writing a historical novel. He wrote 16 pages today, bringing his total number of pages written to more than 50. How many pages p did Eduardo write before today? Complete the inequality that represents this situation. Then solve the inequality.
Answer:
p > 34
He wrote more than 34 pages before today.
Step-by-step explanation:
Eduardo wrote 16 more pages, increasing his total number of pages above 50.
p = pages he wrote before today
p + 16 > 50
p > 50 - 16
p > 34
He wrote more than 34 pages before today.
what is the slope of a line perpendicular to the following line
y=1/3x-2
Answer:
The slope of a line perpendicular to the line y=1/3x-2 is the negative reciprocal of the slope of that line. The slope of the line y=1/3x-2 is 1/3, so the slope of a line perpendicular to it is -3.

The next number in the given sequence is 256
What is Fibonacci sequence?
Leonardo Pisano Bogollo, an Italian, was the first to discover the Fibonacci sequence (Fibonacci). The numbers in the Fibonacci sequence are all whole numbers: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34,... Each phrase in this infinite sequence—which has 0 and 1 as its initial values—is the sum of the two terms before it. This pattern has been referred to as "nature's secret code."
Sunflowers, daisies, broccoli, cauliflower, seashells, and other spiral-shaped plants all display the Fibonacci sequence.
Observe that, the terms in the sequence are based on the 2 to the power of the Fibonacci series (0,1,1,2,3,5,8 …)
2^0=1
2^1=2
2^1=2
2^2=4
2^3=8
2^5=32
2^8=256

given the triangle below, select all true statements
Answer:
first and fourth statements are true
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180° , so
2x + 1 + x + x + 15 = 180 , that is
4x + 16 = 180 ( subtract 16 from both sides ) ← True
4x = 164 ( divide both sides by 4 )
x = 41 ≠ 49
then
∠ A = 2x + 1 = 2(41) + 1 = 82 + 1 = 83° ≠ 99°
∠ C = x + 15 = 41 + 15 = 56° ← True

(A) The rate of making coffee by coffee maker is 6 mL/second.
(B) The rate of making juice by juice maker is 8 mL/second.
(C) Juice is being made at a faster rate.
What is ratio?Ratio basically compares quantities, that means it show value of one quantity with respect to other quantity.
If a and b are two values, their ratio will be a:b,
Given that,
The rate of coffee made by coffee maker is represented by,
y = 6x (1)
Here, y represents the amount of coffee in mL and x represents the time passed in seconds.
Also, The rate of juice made by juice make can be represented by the given table as,
k = 8h (2)
Here, k represents the amount of juice in mL and h represents the time passed in seconds.
(A)
To find the rate of making coffee, solve the equation (1),
y = 6x
⇒ y/x = 6 mL/second
The rate of making coffee by coffee maker is 6 mL/second.
(B)
To find the rate of making juice, solve the equation (2),
k = 8h
⇒ k/h = 8 mL/second
The rate of making juice by juice maker is 8 mL/second.
(C)
Since, the juice is made at the rate of 8 mL/second and the coffee is made at the rate of 6 mL/second.
Therefore, juice is being made at a faster rate.

B. 7,696 in²
C. 4,784 in²
D. 6,162 in²
The surface area of the model is 4,784 in². Option C. is the answer
How to find the surface area of the model?Given: depth of the television = 4 inches, the height of the television = 39 inches and diagonal length = 65 inches.
From the image attached. You can find the width of the television using Pythagoras' theorem:
Width (W) = √(65²-39²) = 52 inches
Surface area of the model = (area of back and front) + (area of left and right) + (area of top and bottom)
Let H, D and W represent the height, depth and width of the television respectively
Surface area of the model = 2WH + 2WD + 2DH
Surface area of the model = 2×52×39 + 2×52×4 + 2×4×39
Surface area of the model = 4056 + 416 + 312

2. x=6
3. y=30; x=20
Step-by-step explanation:
1.) 180 - 130 = 2x
2x = 50
x = 50/2 = 25
2.) 24 = 3(x+2)
24 = 3x + 6

The number line in the question is presented as follows;
<________|_____|_____|__|__|____|____|____|___|_|____|_____|____>
-5 A B 0 C D 5 [tex]{}[/tex]
Therefore, based on the number line, we get;
The location of the point A is 4 units to the left of the point 0, taking the points to the right of zero as positive, we get;
Each unit to the left of point O, is -1 larger than the previous value, moving from right to left.
The coordinates of the point A is therefore, -1 × 4 = -4
The point A represents -4The point B is two and a half unit to the left of 0, therefore, the point B represents -2 1/2The location of the point C is one unit to the right of 0, therefore, the coordinates of the point C is 1
The point C represents 1The location of the point C = 1 is further right to 0 than the point B = -2 1/2
Therefore;
C > B, which indicates 1 > -2 1/2The correct option is; Point B represents -2 1/2, Point C represents 1, and 1 > -2 1/2

The average of two numbers is 13, and their product is 133. Use the quadratic formula to find the numbers. What is the value of the larger number?
The two numbers are 12 and 14 (using quadratic equation)
Let two numbers be a and b
given,
(a + b)/2 = 13 ⇒ a + b = 26 ⇒a = 26 - b→ eq 1
also,
ab = 133
using eq 1 in ab = 133 we get,
[tex]b^{2}[/tex] - 26b + 133 = 0
using quadratic formula,
[tex]\frac{-b+- \sqrt{b^{2}-4ac } }{2a}[/tex]
we get b = 38,14
if b = 38, a = -12, which doesn't satisfy the question
so, b = 14, a = 12
quadratic equation:
The definition of a quadratic as a second-degree polynomial equation demands that at least one squared term must be included. It also goes by the name quadratic equations. The quadratic equation has the following generic form:
ax² + bx + c = 0
where a, b, and c are numerical coefficients and x is an unknown variable. An example of a quadratic equation is x2 + 2x + 1. Here, an is greater than zero because if it equals zero, the equation will cease to be quadratic and change to a linear equation, such as:
bx+c=0
As a result, we cannot refer to this equation as a quadratic equation.
