What is a factor tree, and how do you know when a factor tree is completed?(5th grade math Please help me.)

Answers

Answer 1

Answer: A factor tree starts with one number, such as 8. You draw to lines, and at the end of each is a possible way to divide 8, such as 4 and 2, because 4*2=8. Then, you divide 4 by 2, which is the only possible way without getting a 1 or a 4. Then, since 2 cannot be divided by 2 or 1.That is a complete factor tree. You can tell if a factor tree is over if you end up with a prime number.

Answer 2

Answer: A factor tree is a tree to represent what are the factors of the number.
Ex: 20:1,2,4,5,10

1x20
2x10
4x5
5x4
10x2
All of this equals 20
*in a factor tree you have to include all the factors of a number

Which ones greater 3/4 or 11/16

Answers

Multiply 3/4 (top to bottom) by 4:
$(3)/(4)$ = $(12)/(16)$

$(12)/(16)$ > $(11)/(16)$

So, the answer is: 3/4 > 12/16

Solve equation
2/3=18/x+5

Answers

Subtract 5 from 2/3 to get -4 and 1/3 or -13/3
-13/3=18/x
Multiply both sides by x to get rid of it from the 18/x
-13/3x=18
Multiply both sides by 3 to get rid of the fraction
-13x=54
Divide -13 from 54
x=-4.1538

The determinant of the given matrix is 8+4xz-8y. Therefore, the determinant depends on the variable.

What is determinant?

Determinants are considered as a scaling factor of matrices. They can be considered as functions of stretching out and the shrinking in of the matrices. Determinants take a square matrix as the input and return a single number as its output.

The given matrix is

$\left[\begin{array}{ccc}1&x&y\n0&2&z\n0&0&4\end{array}\right]$

The determinant of 3×3 matrix can be find using

|C|= a₁(b₂c₃−b₃c₂)−b₁(a₂c₃−a₃c₂)+c₁(a₂b₃−a₃b₂)

Now, 1(2×4-z×0)-0(x×4-y×0)+4(x×z-y×2)

= 8+4xz-8y

The determinant of the given matrix is 8+4xz-8y. Therefore, the determinant depends on the variable.

How do you write 18\42 in simplest form

Answers

divide each numbers by 6

Answer: 3/7

You have to find a common number divisible by both numbers of the fraction until you cannot divide the numbers of the fraction any more. So on your problem 18/42 start by dividing both numbers by say 2
18 divided by 2 gives you 9
42 divided by to gives you 21
Then try dividing them again say by 3
9 divided by 3 gives you 3
21 divided by 3 gives you 7
If you try dividing again you will see that you can no longer divide it so 3/7 would be your answer. I hope that helps.

In an isosceles triangle, the third angle is ten times the measure of each of the congruent angles. What is the measure, in degrees, of the largest angle? Explain how you got this answer.

Answers

The angles of the triangle would be represented by x for the congruent sides and 10x for the 3rd angle.
All of the angles in a triangle equal 180°
The equation would be set up like this:
12x=180
x=15°
10x= 150°
