Step-by-step answer:
If there are 40% students that are girls , and the rest are 250 boys. Then that must mean there are 60% boys. Because that is the compliment.
i)

Answer:
v>-2 ( the > is underlined)
Step-by-step explanation:
Step-by-step explanation:
please, be careful when writing the problem definition.
the formula is as I understand it from the definition
S = 93×log(d) + 65
with log being truly the logarithm to the base 10.
so, we have
150 = 93×log(d) + 65
85 = 93×log(d)
log(d) = 85/93
d = 10^(85/93) = 10^(0.913978495...) =
= 8.203109232... ≈ 8.2 miles
the tornado had traveled 8.2 miles.
