Kayla used 4 isosceles and one square for her figure. each edge of the square was 10 inches. the two congruent sides of the triangles are 13 inches long. the height of the triangles is 12 inches. which figure did kayla construct? what is the surface area of the figure? show your work .

Kayla constructed a square pyramid.

The area of the square is 10*10 = 100.

The area of each of the triangles are 12*5/2 = 30.

In total, we get 30*4 + 100 = 220.

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

70

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
