Tanina needs to buy at least 3 pounds of bananas. if she buys a bunch of bananas that way 42 ounces will she have enough ? explain

No, there is not enough

Step-by-step explanation:

We can tell this because there are 16 ounces in a pound. So we divide the number of ounces she bought by 16 to see how many pounds she got.

42/16 = 2 5/8

Since 2 5/8 is less than 3, we know she does not have enough.

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 3/2 and for decimal: 1.5
