Thank you for the opportunity to help you with your question!

10. From the equation of height one can deduce that g = 16 ft/sec^2

v= u-gt

0 = 230-16*t hence t = 230/16 = 14.38 sec

hence height attained by mice h =-16*14.38^2 +230*14.38+5 = 6.15 ft Answer

time = 14.38 seconds

11.

Shampooo : 0.45x +1.5-0.15x = 2.8

solving we get , 0.3x =1.3 hence x = 4.33 liter

Conditioner = 10-4.33 = 5.666 liters or 5.67 liters Answer
