A tree casts a shadow of 28 feet. at the same time, a biologist who is 7 feet tall casts a shadow of 2 feet.

lilavasa [31]

Ratio of shadow to object's size = 2/7

Then, size of tree would be: 7/2 * 28 = 7 * 14 = 98 feet

So, your final answer is 98 feet

Hope this helps!

The length of a rectangular prism is 8

Lena [83]

Surface area is:

$W=width$
$L=length$
$H=height$

$S=2*(L*W+L*H+W*H)$

replacing the values

$250=2*(8*W+8*1+W*1)$

$250=2*(8*W+8+W)$

$250=2*(9*W+8)$

dived each member by 2

$125=9W+8$

$9W=125-8$

$9W=117$

$\boxed{\boxed{W=13~unit~of~measure}}$

The volume of a rectangular prism is

$V=L*H*W$

$V=8*1*13$

$\boxed{\boxed{V=104~unit~of~volume}}$

Caleb's kayak is 12 3⁄5 feet long. Ava's kayak is 20 2⁄5 feet long. How much longer is Ava's kayak?

USPshnik [31]

7 4/5 feet long because 20 2/5 can't be subtracted by 12 3/5 so you change 20 2/5 to 19 7/5. 19-12=7 and 7-3=4 so the answer is 7 4/5 feet long
