Ivan has 15 yards of green felt and 12 yards of blue felt to make 3 quilts. If Ivan uses the same
total number of yards for each quilt, how many
yards does he use for each quilt?​

We need 5 yards green felt and 4 yards blue felt for each quilt.

Step-wise:

Let length of green felt be 'x' , length of blue felt be 'y' and and number of quilts be z.

If Ivan has 15 yards of green felt and 12 yards of blue felt to make 3 quilts.

⇒15x+12y=3z15x+12y=3z

Now, divide both sides by 3 , we get

5x+4y=1z5x+4y=1z

Therefore, we need 5 yards green felt and 4 yards blue felt for each quilt.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
