Answer:
two polygons are congruent if and only if there exists a composition of translation/rotations that maps one polygon to the other polygon.
(instead of translations/rotations we could write transformations, but there are transformations that also change the size of the figure, so I think that writing translations/rotations is more precise)
Step-by-step explanation:
Two figures are congruent if they have the same shape and size.
So for example, if we have one triangle, and we reflect that triangle along some line, those bot images will have the same shape and size (but maybe different orientations) so the triangles are still congruent.
Also, we could translate the image, or simply rotate it along some point, and the resulting image will be congruent to the initial image.
Then two polygons are congruent if and only if there exists a composition of translation/rotations that maps one polygon to the other polygon.
The composition that maps one polygon to the other polygon to make both congruent is called; Similarity transformation.
In transformations in mathematics, it could involve dilation, translation, rotation e.t.cNow, we are told that there has to be a composition that will map one polygon to another one. This means that the two polygons must have the same shape after transformation.
The only method of transformation that can achieve mapping of one polygon to another is called similarity transformation.Read more about Similarity transformations at;

The growth of a certain organism can be modeled by C(t)=10(1.029)^24t, where C(t) is the total number of cells after t hours. Which function is approximately equivalent to C(t)?
1. C(t) =240(0.083)^24t
2. C(t)=10(.083)^t
3. C(t)=10(1.986)^t
4. C(t)= 240(1.986)^t/24
Given:
The function is:
[tex]C(t)=10(1.029)^{24t}[/tex]
Where, C(t) is the total number of cells after t hours.
To find:
The function that is approximately equivalent to C(t).
Solution:
We have,
[tex]C(t)=10(1.029)^{24t}[/tex]
It can be rewritten as:
[tex]C(t)=10(1.029^{24})^{t}[/tex] [tex][\because (a^m)^n=a^{mn}][/tex]
[tex]C(t)\approx 10(1.986)^{t}[/tex] [tex][\because 1.029^{24}\approx 1.986][/tex]

Step-by-step explanation:
if (1x2y6z) is a number divisible by 9 , then what os the least value of x+ y+z ?
Given:
Number 1X2Y6Z is divisible by 9.
To find:
The least value of X+Y+Z = ?
Solution:
First of all, let us learn the divisibility rule of 9.
A given number will be divisible by 9 if and only if the sum of digits of the given number is also divisible by 9.
For example:
Let us consider a number 923463.
The sum of digits = 9 + 2 + 3 + 4 + 6 + 3 = 27
27 is divisible by 9 so the number 923463 will also be divisible by 9.
Let us consider another example 8972.
Sum of digits = 26
26 is not divisible by 9 so the number 8972 will also be not divisible by 9.
Now, we are given the number 1X2Y6Z.
Sum of digits = 1 + X + 2 + Y + 6 + Z = 9 + X+Y+Z
The number 1X2Y6Z will be divisible by if 9+X+Y+Z is divisible by 9.
The least value of X+Y+Z can be zero, so the sum of digits = 9 + 0 = 9
which will make the number 1X2Y6Z divisible by 9.
So, the answer is:
Least value of X+Y+Z = 0 so that the number 1X2Y6Z is divisible by 9.
9514 1404 393
Answer:
0
Step-by-step explanation:
For a number to be divisible by 9, the sum of the digits must be divisible by 9. The given digits total 9, so x+y+z must be a multiple of 9. The least possible multiple of 9 is 0.
The least value of x+y+z is 0.

Answer:

Step-by-step explanation:
Ok to solve this we can write this as
80 = [tex]\frac{73+82+85+83+x}{5}[/tex]
We put the equation like this because were finding out how much he needs to get on his 5th test x in order to get a 80%
Your grade is the average of all of your scores hence the divided by 5
We next multiply both sides of the equation by 5 to get
400 = 72+82+85+83+x
400= 322+ x
78 = x
He must get a 78% minimum on his next test to get 80%

James has a board that is 3/4 foot long he wants to cut the board into pieces that are each 1/8 foot long long division
Answer:
6 pieces can be cut out of the board
Step-by-step explanation:
The complete question is
James has a board that is 3/4 foot long. He wants to cut the board into pieces that are each 1/8 foot long. How many pieces can James cut from the board?
Solution
Given,
The total length of the board is equal to [tex]\frac{3}{4}[/tex] feet
Total number of pieces to made = X
Size of each piece that is cut from the board is [tex]\frac{1}{8}[/tex] feet long
Total number of pieces that can be cut from the board is equal to total size of board divided by size of each sub part
[tex]X = \frac{\frac{3}{4} }{\frac{1}{8} } \\X = \frac{3}{4} * \frac{8}{1} \\X = 3 * 2 \\X = 6[/tex]
Hence, 6 pieces can be cut out of the board
solve: log3(x)+log3(x-2)=log3(x+10)
log3 ( x ) + log3 ( x - 2 ) = log3 ( x + 10 )
log3 ( x )( x - 2 ) = log3( x + 10 )
log3 ( x^2 - 2x ) = log3( x + 10 )
x^2 - 2x = x + 10
x^2 - 3x - 10 = 0
( x - 5 )( x + 2 ) = 0 ==》x = 5 Or x = - 2

2 + (4h- 1) = 13h
Need All Steps Plz
Answer and Step-by-step explanation:
For this equation, we are solving for h.
We are given the equation:
2 + 4h - 1 = 13h
First, we need to Simplify the equation.
2 - 1 + 4h = 13h
1 + 4h = 13h
Now, we need to Subtract 4h from both sides of the equation.
1 + 4h - 4h = 13h - 4h
1 = 9h
Finally, we Divide both sides by 9 to get h.
[tex]\frac{1}{9} = h[/tex]
h is equal to [tex]\frac{1}{9}[/tex].
To check your answer, we plug [tex]\frac{1}{9}[/tex] back into the given equation.
[tex]2 + 4(\frac{1}{9} ) - 1 = 13(\frac{1}{9} )\\\\\\\\2 + \frac{4}{9} -1 = \frac{13}{9} \\\\\\1 = \frac{9}{9} \\\\1 = 1[/tex]

split 50 into the ratio 9:1 what is the answer
Answer:
46
Step-by-step explanation:
The numbers 45 and 5, in the ratio of 9:1, when added together, sum up to 50.
To split the number 50 into a specific ratio, 9:1. This means we need to divide 50 into two parts, where one part is nine times larger than the other part.
To split 50 into the ratio 9:1, we need to divide the number 50 into two parts, let's call them "x" and "y." The ratio 9:1 tells us that one part is nine times larger than the other. So, we can express this relationship mathematically as:
x = 9y
Now, we know that the sum of the two parts, x and y, should add up to 50:
x + y = 50
Since we have an expression for "x" in terms of "y," we can substitute it into the second equation:
9y + y = 50
Now, let's combine the y terms:
10y = 50
Next, we isolate "y" by dividing both sides of the equation by 10:
y = 50 / 10
y = 5
Now that we've found the value of "y," we can use it to find "x" using the first equation:
x = 9 * 5
x = 45
So, the two parts are x = 45 and y = 5. We can verify that the ratio is indeed 9:1:
x / y = 45 / 5 = 9
And the sum of the two parts is:
45 + 5 = 50
The numbers 45 and 5, in the ratio of 9:1, when added together, sum up to 50.
In summary, to divide 50 into the ratio 9:1, we found that one part (x) is 45, and the other part (y) is 5. This satisfies the condition that one part is nine times larger than the other, and their sum is 50.
