Answer:

40%

Step-by-step explanation:

Well, 6/15 of the pieces of fruit are apples, so all you have to do is divide 6 by 15 to give you 0.4. This means you have 0.4 out of 1, which, if you multiply by 100, would give you 40 percent.

PLEASE HELP!! Need to finish my quiz!!

Answer:

Square

Step-by-step explanation:

Given are 3 options with same dimension of 12 feet. The condition is base area should be minimum for maximum volume

A) A hemisphere has

$V=\frac{2}{3} \pi (\frac{12}{2} )^3\\=452.57\\Base area = \pi (\frac{12}{2} )^2\\=113.04\\Ratio=4.00$

B) A cube with side length 12 ft

$V=6^3 =216\\Base area = 36\\Ratio = 6$

C) A cone with diameter 12 ft and height 10 ft

$V=\frac{1}{3} \pi(6^2)10\\=377.14\\Base area =113.04\\Ratio =3.34\\$

D) A square pyramid

$V=\frac{lwh}{3} \\=\frac{144(9)}{3} \\=432\\Base area = 144\\Ratio =3$

To maxmize the ratio of floor area to volume, we have to maximise the ratio of volume to floor area

Hence of these 4 figures square is the best one that meets the criteria
