B percent of something (x)
means: b/100 * x
ex: (2)
20% of 120 = 20/100*120 = 24
ex: (4)
18 = 40 % of x
means: 40*x/100 = 18
x=45
and so on
hope that helps

Answer:
Step-by-step explanation:
make a graph of what we need more of an explanation
45 minutes x 22= 990, 990 divided by 60 is 16.5 hours or 16 and 1/2 hours
"deci" means ten. So 3x10 = 30. With this information the answer is obvious that it is equal not more than.
Answer:

is the fraction of sensors upgraded per unit.
Step-by-step explanation:
We are given the following in the question:
Let x be the number of upgraded sensors in one unit and y be the number of non-upgraded sensors in one unit.
Number of modular units = 30
Since some part of unit is upgraded and some are non-upgraded, then, we can write the equation:

Number of non-upgraded sensors =

Thus, we can write the equation:

Fraction of sensors upgraded per unit =
