First, solve the exponent part because it has a higher precedence than multiplication. And we have a negative exponent. Which means we takes the reciprocal of 4 then take to the power of 4.
4^-4 = 1/4^4 = 1/256
Now do the multiplication part.
16 * 1/256 = 1/16
453.10/734 = .617% * 100 = 61.7% --> 62%
D. 62%
The answer is <span>2.25
You could multiply 0.5 by 72, then by 36, then by 18, and so on, until you found the 6th term.

In this question, you're solving for x.
Solve for x:
x + 4.2 = 7
You need to get x by itself, to do so, you would need to subtract 4.2 from both sides:
x = 2.8
Answer:
x = 2.8
Distance = (rate)(time)
In this problem, note that both girls traveled the same distance.
Karens distance = r * 1.5 hrs we dont know her rate
Nancy distance = 50 * 1 hr we know she started 30 min later
but arrived at the same time
since the distances are equal
r*1.5 = 50 * 1 all you have to do is solve for r
1.5r = 50
r = 50/1.5
r = 33 1/3 miles per hour
