WILL MARK BRAINLIES For every 1/4 of an inch a boy grows, he gains 3/4 of a pound. If the boy weighs 64 pounds when he is 52 inches tall, how many pounds will he weigh when he is 53.5 inches tall?

64-53=11-0.50=10.50

Step-by-step explanation:

brainliest please

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
