I think the answer is maybe A
Let x and y be islands and peninsulas respectively
x+y=191919
2x+3y=454545
y = 191919- x
2x + 3 (191919 - x) = 454545
2x + 575757 - 3x = 454545
2x-3x = 454545 - 575757
-x = -121212
x = 121212
121212 + y = 191919
y = 191919 - 121212
y = 70707
Ni Hua visited 121212 islands and 70707 peninsulas
23/ 4621 is 0.00497728, if you meant 4621/ 23 then it's 200.913043.
to graph f (x) + k, move the graph k units up..your answer should be;
y = x ^ 2 + 5/2
<span>The proper sequence John would use to find the measure he wants.is given as follows:
Step 1: </span><span>John drives a stake opposite the tree to establish a line between two points.
Step 2: </span><span>John uses a compass to walk away from the stake at a right angle.
Step 3: </span><span>On the path John walks until he finds a line of sight to the tree that equals 60 degrees.
Step 4: </span><span>John drives a second stake in the ground.
Step 5: </span><span>John measures the distance between the two stakes.
Step 6: </span><span>John multiplies the distance between the two stakes by 1.7 to find the distance.</span>
