liberstina [14]

Answer:

Step-by-step explanation:

Given Annabella time for a race is 24.2 seconds, if another runnee's time was 6.43 seconds faster, then the time taken for another  runnee's time will be 24.2 - 6.43 = 17.77secs.

Let a variable X be the difference between annabelle's time and the other runners time.

X = annabelle's time  - other runners time.

X = 24.2 - (24.2 - 6.43)

X = 24.2-24.2+6.43

X = 6.43seconds

Hence the expression between annabelle's time and the other runners time is X = 24.2 - (24.2 - 6.43)

<em>The difference between annabelle's time and the other runners time is 6.43seconds</em>

Answer:

x = 36

y = 37.95

Step-by-step explanation:

By geometric mean property:

{12}^{2}  = 4 \times x \\  \\ 144 = 4 \times x \\  \\ x =  \frac{144}{4}  \\  \\ x = 36 \\  \\

By Pythagoras Theorem:

{y}^{2}  =  {12}^{2}  +  {x}^{2} \\  \\  {y}^{2}  =  {12}^{2}  +  {36}^{2}  \\  \\  {y}^{2}  = 144 + 1296 \\  \\  {y}^{2}  = 1440 \\  \\ y =  \sqrt{1440}  \\  \\  y = 37.95
