Thx, 5 star and brainliest for first

In calculating this, you would have to find the unit price first.

$13 per 3 1/4 yards is also equal to $4 per yard.

Then you would have to find out the other ones' unit prices.

a) $16 per 4 2/3 yards is equal to around $2.82 per yard, so No

b) $11 per 2 3/4 yards is equal to $4 per yard, so Yes

c) $26 per 6 1/2 yards is equal to $4 per yard, so Yes

I solved these by dividing the amount of money by the amount of string.

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
