The 8 is in the tenth place. There is a 7 in the hundredths place. Since 7 is greater than or equal to 5, we round the 8 up. So it becomes a 9.

Answer: 1129.9
Answer:
20ln(3)
Step-by-step explanation:
Put 15 for A and solve for t.
15 = 45e^(-.05t)
15/45 = 1/3 = e^(-.05t) . . . . divide by 45
ln(1/3) = -.05t . . . . . . . . . . . take natural logs
20ln(3) = t . . . . . . . . . . . . . . multiply by 20, simplify
It will take 20·ln(3) years for the area to decrease to 15 km^2.
I believe the answer is C because each teacher would get 2 packs for the three that get paper
That would simply be
38.14 ÷ 4 = 9.535
thus he scored 9.535 on each event
The correct answer is B. So for A, 8m is smaller than 12 m. For B, 20 m is Bigger. For C, Find how many meters is 1 centimeter, the answer is 1 cm : 12m, the meter is not bigger than 12, but the same, so C is wrong. For D, divide both sides by 3 to find 1 CM, the answer is 1 cm : 5 m, it is wrong.
