Answer:

59 minutes

Step-by-step explanation:

In the table of values ​​it is observed that for each day of training 2 minutes are increasing and that day 1 begins with 5 minutes of training , so

y(x)=2\frac{min}{d}(x)+3min, where x= evaluation day

we have to for the day 28

y(28)=2\frac{min}{d}(28d)+3min=59min

t=\sqrt{\dfrac{ab-s}{r+ak}}\\\\t^2=\dfrac{ab-s}{r+ak}\\\\rt^2+akt^2=ab-s\\\\akt^2-ab=-rt^2-s\\\\a(kt^2-b)=-(rt^2+s)\\\\a=-\dfrac{rt^2+s}{kt^2-b}\\\\a=-\dfrac{rt^2+s}{-(b-kt^2)}\\\\a=\dfrac{rt^2+s}{b-kt^2}

A news paper article reports the results of an election between candidates the article says that smith received 60% of the votes
Leokris [45]
If you want some help here, I can tell you!

60% is 60%, since the best way to find out is by converting the two numbers into percents.

You need to find out a decimal first for the second number in order to convert it to a percent. To find a decimal out of a fraction, you put the numerator in the house (I forgot what it was called) and then you put the denominator out. You divide, and you find that 1/3 is actually a repeating decimal, 0.33333333 and so on. You round to 0.34, and that's 34% since 0.34 is 34 out of 100, basically. 34% plus 60% is NOT 100%, and 100% is a whole, so that's why it isn't accurate.
