The total number of yellow marbles in the bag was 78 marbles

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

Given data ,

The ratio of yellow marbles to purple marbles in the bag = 13 : 4

Let the total number of yellow marbles in the bag be = 13x

Let the total number of purple marbles in the bag be = 4x

Now , the equation will be

The total number of marbles in the bag = 102

So , substituting the values in the equation , we get

The total number of marbles in the bag = total number of yellow marbles + total number of purple marbles

The total number of marbles in the bag = 13x + 4x

13x + 4x = 102

17x = 102

Divide by 17 on both sides of the equation , we get

x = 6

Therefore , substituting the value of x in the above expressions , we get

Total number of yellow marbles in the bag = 13x

Total number of yellow marbles in the bag = 13 x 6

Total number of yellow marbles in the bag = 78 marbles

And ,

Total number of purple marbles in the bag = 4x

Total number of purple marbles in the bag = 4 x 6

Total number of purple marbles in the bag = 24 marbles

Hence , The total number of yellow marbles in the bag was 78 marbles

Explain how to divide an amount by number 3
Greeley [361]

Answer:

Dividing by 3 means splitting a number into 3 numbers, all equal. The division sign can be represented by a /.

For example, 12/3=4. We can check our answer by multiplying our answer by 3, and seeing if we get our original answer.

4*3=12

Division is the opposite of multiplication, so it makes sense that multiplication is a valuable tool to check our work.

Hope this helps!

Find the degree of the polynomial<br> 2x^4y^2+9x^2y^5-3x^4y^4
coldgirl [10]

Answer:

the polynomial has degree 8

Step-by-step explanation:

Recall that the degree of a polynomial is given by the degree of its leading term (the term with largest degree). Recall as well that the degree of a term is the maximum number of variables that appear in it.

So, let's examine each of the terms in the given polynomial, and count the number of variables they contain to find their individual degrees. then pick the one with maximum degree, and that its degree would give the actual degree of the entire polynomial.

1) term  2\,x^4\,y^2  contains four variables "x" and two variables "y", so a total of six. Then its degree is: 6

2) term  9\,x^2\,y^5  contains two variables "x" and five variables "y", so a total of seven. Then its degree is: 7

3) term  -3\,x^4\,y^4  contains four variables "x" and four variables "y", so a total of eight. Then its degree is: 8

This last term is therefore the leading term of the polynomial (the term with largest degree) and the one that gives the degree to the entire polynomial.
