Answer:
y = 0.55 or 5 / 9
Step-by-step explanation:
here's the solution :-
=》y + 7 = 19y - 3
=》7 + 3 = 19y - y
=》18y = 10
=》y = 10 ÷ 18
=》y = 5 ÷ 9
=》y = 0.55
Answer: I attached a picture of the graph
You can square the whole problem to cancel out the square root. Might make things easier.
Just count the notches between the two points, there are 15 notches so 15 is tour answer
Answer:
E. 300
Step-by-step explanation:
A rectangle split in half diagonally yields 2 right triangles.
((For this problem, you are probably supposed to use the pythagorean theorem to find the diagonal length, and then calculate perimeter (length of fence around triangular field). In other words:
(sqrt( (50m)^2 + (120m)^2 )) + 50m + 120m)
))
By definition, the hypotenuse (diagonal) is the longest side.
This means that it must be longer than 120m.
If you add the 2 sides (50m + 120m), you get 170m.
Since the third side has to be longer than 120m, the answer _must_ be over 290m (170m + 120m).
300m is the only answer that fits.
