I think any irrational number would do this? I'm not positive though. Some examples may be pi or the square root of 2.

How do you answer this question.
Ipatiy [6.2K]
Lets write this out:-

\frac{50}{100} + \frac{30}{100}

To answer this we just need to add the numerators of both fractions because the denominator's are already common multiples. 

\frac{50}{100}+ \frac{30}{100} = \frac{80}{100}

Now lets simplify \frac{80}{100}.

\frac{80/20}{100/20}=  \frac{4}{5}

So, \frac{50}{100}+  \frac{30}{100} = \frac{80}{100}= \frac{4}{5}

Hope I helped ya!! xD

Martin is paid an hourly rate of d dollars per hour for the first 40 hours he works per week. He is paid one-and-a-half times hi
Nat2105 [25]

Answer:

40d + 10(1.5d) = 770 can be used to determine Martin's hourly pay.

Step-by-step explanation:

Given that:

Hourly rate = d

Earning to first 40 hours = 40d

Earning of more than 40 hours = 1.5d

Amount paid per week = $770

Hours worked = 50 hours

first 40 hours + 10 hours = total earned

40d + 10(1.5d) = 770

Hence,

40d + 10(1.5d) = 770 can be used to determine Martin's hourly pay.
