Emma is going camping. each side triangle on her tent is 5 feet tall the square base is 4 feet wide what is the surface area of her tent?

The surface area of her tent = 36.661 ft²

Step-by-step explanation:

∵ The tent is shaped square pyramid without base

∴ The tent has 4 triangular faces

∴ Its surface area = area of each triangular face × 4

∵ The triangular face has base of length 4ft and 2 equal sides of

   length 5ft

∴ The height of the Δ =

∴ Its surface area = 4 × = 36.661 ft²

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
