Answer:
(If they were talking about 3,335, then) 100 times greater
(If they were talking about 3,335 then) 10 times greater
Step-by-step explanation:
When you visualize it, ignore the other numbers and think of only the threes.
Count how many spaces/places they are from each other, and that's how many 0s you should put after a 1 as your answer.
Same as decimal moving and multiplying by 10's.
Answer:
4
Step-by-step explanation:
First, set the number set from least to greatest:
2 , 3 , 3 , 3 , 5 , 6 , 7 , 10
Next, find the middle number(s) [median]. Note that if there is a even number in the given set (as in this case), you will find the mean of the 2 middle numbers. In this case, the middle numbers are: 3 & 5:
(3 + 5)/2 = (8)/2 = 4
4 is your median.

The opposite of -3.4 would be positive 3.4
You can write the equations of motion as
h(t) = -16t² + v₀sin(θ)t
d(t) = v₀cos(θ)t
Solving the second of these for t and substituting into the first equation gives the time of flight as
0 = -16t² + d(t)·tan(θ)
t = √(d(t)·tan(θ)/16)
So, for d(t) = 400 and θ = π/6, this becomes
t = √((400/16)/√3)
t = 5/√(√3) ≈ 3.79918
The ball is in the air about 3.80 seconds.
The right answers are B and D
