Answer:
8.9 meters
Step-by-step explanation:
this seems like a problem where you can use the pythagorean theorem:
you know one of the two legs (6m) and the hypotenuse (9m), you must find the other leg
a^2 + 6^2 = 9^2
a^2 + 36 = 81
a^2 = 45
a = or
·
which simplifies to be 3
or approx. 8.9 meters
What you gotta take from this problem:
What Joe got during break =
What his sister gave him =
What he has total = 10 tadpoles.
Now to assemble this equation:
Now combine like terms to get
Subtract 2 on each side of the equation to get
Now you would divide 5 on each side and get
, however since you can't have a .6 of a tadpole, you would have to round it up to 2.
