Answer:
they have to be congruent
Step-by-step explanation:
both rectangles have the same perimeter which means there Identical
If two rectangles have the same perimeter, they
do not have to be congruent is the correct option.
Given,
If two rectangles have the same perimeter.
We need to find whether both rectangles are congruent.
What is the perimeter of a rectangle?The perimeter of a rectangle is given by:
P = 2 ( Length + width )
Now,
Let the two rectangles be A and B.
Rectangle A:
Let,
Length = 2
Width = 4
Now,
Perimeter = 2 ( 2 + 4 ) = 2 x 6 = 12
Rectangle B:
Let,
Length = 3
Width = 3
Now,
Perimeter = 2 ( 3+ 3 ) = 2 x 6 = 12
We see that both rectangles have the same perimeter even if they have different lengths and widths so the rectangles need not be congruent.
Thus,
If two rectangles have the same perimeter, they do not have to be congruent.

Explanation:
We have these three rules for scale factors
scale factor > 1, enlarge the image0 < scale factor < 1, shrink the imagescale factor = 1, the preimage and image are identicalWith those rules in mind, we have enlargements for these transformations.
P to QP to RQ to RAll of which represent some scale factor larger than 1. We don't have enough information to pinpoint what that scale factor would be.
In other words, if you go from small to big, then you apply some scale factor larger than 1 to enlarge the image.
----------------
We also have these reductions
Q to SR to PThis is where we go from big to small. The image shrinks and we use some scale factor between 0 and 1.
----------------
And finally we have these transformations in which the size of the image does not change. Therefore the scale factor is 1.
P to SS to PThe order doesn't matter for this subset, but the order will matter for the other batches of transformations.
What is the length of b
Answers
Answer:
b = 24
Step-by-step explanation:
Concepts
The Pythagorean Theorem states that the sum of the squares of the two other sides on a right triangle is equal to hypotenuse (longest side) squared. It can be represented by the equation \(a^2+b^2=c^2\). We can also use this formula to solve for the other two legs in the right triangle.
Application
In this case, we're asked to find the length of b in the right triangle, given c as 26 and a as 10. Now, we just apply the formula and solve for b.
Solution
Step 1: Set up equation and simplify.
\(10^2+b^2=26^2\) \(100+b^2=676\)Step 2: Subtract 100 from both sides.
\(100+b^2-100=676-100\) \(b^2=576\)Step 3: Take square root of both sides.
\(\sqrt{b^2} =\sqrt{576}\) \(b=24\)Therefore, b = 24.

Find the volume of a pyramid with a square base, where the perimeter of the base is
16.9 cm and the height of the pyramid is 19.6. Round Your answer to the nearest tenth of the cubic centimeter.
Answers
Answer:
116.6
Step-by-step explanation:
Volume = ⅓ × area of base ×height. We don't have the area of base, we need to find it.
Perimeter (4×Length) = 16.9 cm
Length = 16.9÷4 = 4.225 cm
Area = L² = 4.225² =
Volume of pyramid = 1/3 × 4.225² × 19.6 = 116.624 = 116.6 cm³

What is the value of x in the proportion?
A: 2 2/5
B: 5 2/5
C: 8 1/10
D: 12 3/20
Answers
Explain
n= (2 1/4)/x=(1 1/2)/(3 3/5) we should change is to easy fraction
(9/4)/x=(3/2)/(18/5)
(9/4)=2.25
(3/2)=1.5.
(18/5)=3.6
Substitute those fraction number with decimal number that makes easy to calculate
2.25/x=1.5/3.6 now we should do cross multiple
That means 2.25*3.6=8.1
1.5*x= 1.5x
8.1=1.5x divide both side with 1/5
X=5.4

B, 5 2/5

9/4 or 2.25
Explanation:
Put 6 over a one (6/1)
Now multiply 6/1 by 3/8 = 18/8 (what you do is you multiply the top, then bottom)
Now simplify:
Both have 2 in common so we would do 18 divided by 2 (9)
Then 8 divided by 2 (4)

Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)
Answers
Answer:
Sure, I'll explain the cosine rule and sine rule in simple terms:
The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.
Here's an example of how to use the cosine
Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.
Using the cosine rule:
a^2 = b^2 + c^2 - 2bc * cosA
where A is the angle opposite side a, we can plug in our values and solve for a:
a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)
a^2 = 64 + 36 - 96 * 0.707
a^2 = 10.56
a = sqrt(10.56)
a = 3.25 (rounded to two decimal places)
Therefore, the length of side a is approximately 3.25 units.

The sum of two numbers is 88; one number is 12 less than the other. What is the larger number? 1. Cut the _______ number in half. Write both halves on your paper. 2. Cut the ______________in half. 3. Now ADD half and SUBTRACT half from each side.
Answers
Answer:
50
Step-by-step explanation:
I have set up an equation, where 'x' is the larger number:
x + (x - 12) = 88
Solve for 'x':
x + (x - 12) = 88
x + x - 12 = 88
2x - 12 = 88
2x -12 + 12 = 88 + 12
2x = 100
2x/2 = 100/2
x = 50
The larger number should be 50.
