So, I didn't quite understand your question clearly, but I'll try my best to answer it.

So, the first question is quite simple: Did the runner have a % decrease in his time or an increase.
Well, 7:45 is minor than 5:51. So, his time decreased.

2nd question:
The percent of change. Well, first things first 7:45 has 2 different units, wich are minutes and seconds, I suppose. Same goes for 5:51.
So let's put everything in seconds. multiply both the 7 and 5 for 60(for every minute has 60 seconds.)

That means:
7*60= 420+45 = 465.
5*60=300+51=351.

Now, let's do the math itself:
465 -> 100%
351 -> x%
 Is equal to about  75,5%
How much did it decrease then?
(75,5-100)%= 24,5%, approximately

Does the expression 1.016x represent a percent increase greater than 12% if the original amount is x? How could I rewrite the ex
GrogVix [38]

Answer:

The expression 1.016x does not represent a percent increase greater than 12%.

Step-by-step explanation:

We are asked to find whether the expression 1.016x represent a percent increase greater than 12% if the original amount is x.

First of all, we will find 12% increase. The total amount after x% increase would be original amount plus 12% of original amount.

\text{12 percent increase}=x+\frac{12}{100}x

\text{12 percent increase}=x+0.12x    

\text{12 percent increase}=1.12x

Since 1.12 is greater than 1.016, therefore, the expression 1.016x does not represent a percent increase greater than 12%.

We can rewrite 1.016x as:

1.016x=1x+0.016x=x+0.016x

Let us convert 0.016 to percent by multiplying by 100.

0.016\times 100\%=1.6\%

Since 1.6% is less than 12%, therefore, the expression 1.016x does not represent a percent increase greater than 12%.
