<span>The problem is basically asking you to approximate the square root of numbers that are not perfect squares. You should be able to recognize that 54 is very close to 49 and you should know that the square root of 49 is 7. You should also know that the next perfect square is 64 (whose square root is 8). Therefore the square root of 50 is between 7 and 8, but closer to 7 since 50 is closer to 49.</span>
X^3=8
x^3=2^3
Therefore, x=2
Hours = 34
Income per hour = 12.5$
Service calls = 6
Income per call = 4
Therefore, total income
= (time of working * income per hour) + (service calls * income per call) = (34*12.5) + (6*4)
= 425+24
= 449
Well, 6/8 can be simplified: divide the numerator and denominator by 2, then your simplified fraction is 3/4. Now, multiply straight across: 4 times what=12? 3 does. So, you do the same thing to the numerator, because whatever you do to the denominator must be done to the numerator, and same reversed. 3*3=9, so the answer to this is 9/12!!
Given:
a.) The population of Arizona is estimated to increase by 6.2% every year.
b.) The population was 4.18 million in 2016.
For us to be able to determine the population in 2022, we will be using the following formula:

Where,
P = Total population after time (t)
P₀ = Starting population = 4.18 million
r = Growth rate (in decimal form) = 6.2%/100 = 0.062
t = time (in years) = 2022 - 2016 = 6 years
e = Euler's number = 2.71828182845
We get,


Therefore, the population in 2022 will be approximately 6,063,646.
