Question:
Is triangle AFD congruent to triangle BEC?
Answers
Answer: is not congruent
To be congruent, it has to be same size and shape. It can face in any directions. Both the shapes have to be equal in all side lengths and equal angles.
Looking at the triangle you can understand that it is not congruent as the triangles have a size difference of being big and small. But if you still desire detailed explanation then here:
There is four rules for a triangle to be congruent. If one of these rule matches then you can say the triangle is congruent.
1. The three sides are equal
2. Two angles are the same and a corresponding side is the same
3. Two sides are equal and the angle between the two sides is equal
4. Two angles are equal and the side between them is equal
There are no angles, so find if all the three sides are equal. Even if one side is not equal, you can say it is not congruent. So if you just measure any side length of the smaller and big triangle, the length is not equal. None of the side lengths in either of the triangle is equal.

95 is not a term here as the next verse should be 98 as it is a 94 term in this pattern

What is arithmetic sequence ?An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence.
The given sequence of numbers is,
1, 5, 9, 13, 17, .....
The first term of the given sequence a₁ =1,
From the given sequence, the common difference pair of two consecutive terms d = 4,
Let nth term of the sequence aₙ= 95,
By arithmetic sequence formula,
aₙ = a₁ + (n-1).d
Substitute the value of aₙ and d,
95 = 1 + (n-1).4
94 = (n-1). 4
(n-1) = 23.5
n = 24.5
The value of n can't be decimal, so 95 can't be a term of the given sequence.

Maggie's brother is 7 years younger than four times her age. The sum of their ages is 68.
How old is Maggie?
Answers
=============================================
Explanation:
m = Maggie's age (some positive whole number)
4m = four times her age
4m-7 = seven years younger than 4m = brother's age
Add up her age (m) and her brother's age (4m-7) to get a sum of 68.
m+(4m-7) = 68
5m-7 = 68
5m = 68+7
5m = 75
m = 75/5
m = 15
Maggie is currently 15 years old.
Her brother is currently 4m-7 = 4*15-7 = 60-7 = 53 years old.
Their current year ages add to: 15+53 = 68 which confirms the answer.

A triangle has side lengths of 2 feet, 5.4 feet, and 5 feet. The angle measures are 90 degrees, 73 degrees, 17 degrees. Another triangle has side lengths of 3 feet, 8.1 feet, 7.5 feet. The angle measures are 90 degrees, 73 degrees, 17 degrees. Are the triangles similar? If so, what is the scale factor going from the top triangle to the bottom triangle?
Answers
Answer:
Yes. The factor is 3/2 (=1,5)
Step-by-step explanation:
They have all the 3 angles congruent, so they are similar. You calculate the scale factor by dividing the hypotenuse (for example) of the second triangle by the hypotenuse of the first one.
Answer:
1) yes 2) 1.5

Y+2= 1/3(x+6)
Solve for y
Answers
Answer:
y = 1/3x
Step-by-step explanation:
Alright, so we have an equation with two variables (y and x) and I need to solve for y in terms of x. That is, I need to isolate y one one side with all the other terms on the other side.
First, let's distribute the 1/3 on the right side of the equation onto the x and 6 inside the parentheses.
y + 2 = 1/3(x + 6)
y + 2 = 1/3(x) + 1/3(6)
y + 2 = 1/3x + 2
Now, let's isolate y on the left side by removing 2 from both sides.
y + 2 = 1/3x + 2
y + 2 - 2 = 1/3x + 2 - 2
y = 1/3x
So, y is equal to 1/3x. Hopefully that's helpful! :)

Step-by-step explanation:
[tex] {5}^{2} + {2}^{2} = 25 + 4 = 29 \\ \\ {6}^{2} + {1}^{2} = 36 + 1 = 37[/tex]
The values are 29 = 5² + 2² and 37 = 6² + 1².
What is square of number?The definition of a square number states that they are numbers that have been multiplied by themselves. In other terms, a natural number is referred to as a square number if it is multiplied by itself.
Decimal squares are fairly simple to calculate, and the process is the same for both whole numbers (integers) and decimals.
Given numbers 29 and 37
to express in form of sum of two square
let = 29 = a² + b²
the perfect square number near 29 is 25
29 = 25 + 4
29 = 5² + 2²
and 37 = a² + b²
the perfect square near 37 is 36
37 = 36 + 1
37 = 6² + 1²
Hence the numbers in sum of two squares are,
29 = 5² + 2² and 37 = 6² + 1²

A 9-foot roll of waxed paper costs $4.32. What is the price per inch?
Answers
The price per foot is $0.91
Step-by-step explanation:
A 6-yard roll of butcher paper costs 16.38
1 yard = 3 foot
6 yards = 3 times 6 = 18 foot
the cost of 18 foot is $16.38
To find price per foot, we divide the cost of 6 yards by 18
16.38÷ 18 = 0.91
The price per foot is $0.91
