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
Answer:
<u>2.75</u>
Step-by-step explanation:
3/4 (three fourths) plus 2 =<u> 2.75!</u>

A square side is twice of the radius
sq side: 4 x 2
sq side: 8
find the area of the square.
A = b x h
A = (8) x (8)
A = 64
<em>Area of square is 64</em>

Find the area of the circle
Area of circle:
A = πr²
A = π(4)²
A = 16π
A = 16(3.14)
A = 50.24
----------------------------------------------------------------------------------------------------------------
Divide the circle from the total
50.24/64
50.24/64 = 0.785
0.785 = 78.5/100 = 78.5%
----------------------------------------------------------------------------------------------------------------
Subtract the circle's percentage from 100% (the total)
100 - 78.5 = 21.5
21.5% is your chance of not hitting a point in the circle.
-----------------------------------------------------------------------------------------------------------------
21.5%, or (B), is your answer
