The ratio of the number of buttons in Package A to the number of buttons in Package B can be represented as :12.

For every button in Package C, there are
buttons in Package D.

The ratio of buttons in Package A to the total number of buttons in all five packages can be represented as
:5.

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

the answer is a i belaeve atleast thats what my calculator just gfave me

step-by-step explanation:

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

x = 12

y = 1

for the points!
