10. If ABCD is a kite, DB=48 in. and CE=7 in. find DC. * 49 in.
23 in.
25 in.
47 in.

25 in.

Step-by-step explanation:

DEC is a right triangle. <DEC is a right angle.

(DE)² + (EC)² = (DC)²

DE = ½DB = ½(48 in.) = 24 in.

(24 in.)² + (7 in.)² = (DC)²

576 in.² + 49 in.² = (DC)²

(DC)² = 625 in.²

DC = 25 in.

a.480 feet

b.$96 because you would have to divide and I knew where to place the decimal because since it's money, that's where it would go.

c. I don't know what the expression is but the answer is 2500 yards.

Step-by-step explanation:

a.64 x 2.5=160y = 480f

ratio-1y=3f

b.480 divided by 0.20

c.1000 x 2.5
