Doris uses 6 square pieces of fabric to make one scarf. Each side of a square piece of fabric is one third yard in length. Doris

brilliants [131]

Answer:

5 large pieces of fabric.

Step-by-step explanation:

Length of each side of a square piece of fabric = $\frac{1}{3}$ yard

Area of a Square = Length X Length

Area of one square piece of fabric = $\frac{1}{3}$ X $\frac{1}{3}$ = $\frac{1}{9}$ square yard.

To make one scarf, Doris uses 6 square pieces.

Area of one scarf = $6 X \frac{1}{9}= \frac{6}{9}=\frac{2}{3}$ square yard

Each large pieces of fabric is one-third yard long and 2 yards wide.

This is clearly a rectangle,

Area of a Rectangle = Length X Width

Area of each large piece of fabric= $\frac{1}{3}X 2=\frac{2}{3}$ square yard.

Since the Area of one scarf is equal to the area of each large piece of fabric, in order to make 5 scarves, Doris would need 5 large pieces of fabric.

2+5k=3k-6 i need the steps to solve this . i am struggling to find the answer. can you help me?

Katarina [22]

Ok, so what you're going to do is add the -6 to the other side and combine it with the number 2 making it 8, then you are going to subtract the 5k from the left side and add it to 3k so if you now have a -5k + 3k it would = -2k then you would take the 8=-2k and divide each side by -2 which leaves you with -4=k

Complete the table Original Price:? Percent of Discount: 25% Sale Price: $40

BigorU [14]

Answer:

The original price would be 50$.

Step-by-step explanation:

To find this answer you have to divide 25% by 100, which equals 0.25. Now multiply 0.25 by 40 and you get 10$. Since 10$ was the discount, you just add 10$ + 40$, therefore 50$ is the original price.
