Valentina is cutting three different-sized circular mirrors to fit in a piece of art. The radius of the medium-sized mirror will be 40% larger than the radius of the smallest mirror, and the radius of the largest mirror will be 40% larger than the radius of the medium-sized mirror. If the radius of the smallest mirror is 1/2 foot, what will be the area, in square feet, of the largest mirror? A 2.5 B 3.0 C 5.3 D 6.2

x=half

step-by-step explanation:

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

yes

step-by-step explanation:

yes

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
