What is equivalent to 5^3 ( choose all that apply)
a)5^7*5^-4
b) 5^12/5^4
c) 5+5^2
d) 5^0*5^3
e)5^3-5^0

A, and D

Step-by-step explanation:

A works because when you multiply like bases, you add exponents, so we have...

  5^7*5^-4 = 5^(7+(-4)) = 5^(7 -4) = 5^3

B  doesn't work because when you divide like bases, you subtract the exponent of the denominator from the exponent of the denominator...

  5^12/5^4 = 5^(12 - 4) = 5^8

C doesn't work because there is addition.  

 5 + 5² = 5 + 25 = 30, and 5³ = 125

D works because 5^0 = 1, so we have

  5^0(5^3) = 1(5^3) = 5^3

E doesn't work because there is subtraction...

  5^3 - 5^0 = 5^3 - 1 = 124

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

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%
