The 3rd one
This is because in the graph it’s looking for numbers 70-79 but only with 2 numbers and the 3rd is the only one that fits in the description.
3minutes 45 seconds = 3 45/60 = 3.75 minutes
28 copies/ 1 minute = x copies/3.75 minutes
using cross products
28 * 3.75 = 1 * x
105 = x
We can print 105 copies in 3 3/4 minutes
Your answer is5x^4 * sqrt 3x
That would be 314 because 100xpi
Hello,
Let's assume x the time the express runs.
56*x=35*(1.5+x)
==>21x=52.5
==>x=2.5 h =2 h 30 min
