Answer:
Step-by-step explanation:
there are infinite numbers between 2 and 3 having average=2.5
2.49,2.51
2.48,2.52
2.47,2.53
2.46,2.54
.................
2.491,2.509
2.492,2.508
2.493,2.507
......................
B and C are correct, A and D are incorrect
100 to 49. Because area is units squared, and it is finding by multiplying the side lengths, you would simply square the ratio.
They are easy to compare if they all have the same common denominator, then you can easily order them by the magnitude of the numerators...
85/10, -67/10, -56/10, 82/10 so now they are easy to compare...so
-6.7, -28/5, 8.2, 17/2
d1 = 51(t)
d2 = 71(8 - t)
d1 + d2 = 508
and now you just have to solve for t.
