Answer:
$11.80 per hour
Step-by-step explanation:
So in the first 30 hours.Julio's rate is r ( the normal hourly rate)
so in the 35 hours we divide it as 30 hours and 5 hours as
30(r) + 5 (1.4r) = 436.60
solve for r : 30r + 7r = 436.60
37r=436.60
Divide both sides by 37 : r= 11.8
Julios normal hourly rate is $11.80 per hour
The answer is
A half life pertains to the time it takes for exactly half of a substance to disappear. So, if U235 has a half life of 700 million years, it will take 700 <span>million years for half of it to decay. That would leave .5kg or 500g.</span>

Answer:
This question seems to be incomplete, I guess that we have a circular pool, with a diameter of 3.5 m.
Now, the circunference of a circle can be written as:
C = 2*pi*r
where:
pi = 3.14
r = radius = half of the diameter = 3.5m/2 = 1.75m
Then replacing those values in the equation for the circumference we have:
C = 2*3.14*1.75m = 10.99 m.
And knowing that the value of pi is actually larger than 3.14 (pi = 3.1415926535....)
We can safely round up the circumference to the next whole number, C = 11m
