Answer:
The answer is 256 + 336 = 592. Although in reality you couldn't play soccer that much in two days.
For every one stone it's 14lb and for every kg it's 2.2 lb therefore you would have to multiply 14 by 9 then divide that answer by 2.2 and that answer will be your answer..
14•9=126
126÷2.2=57.27
You would have 57.27kg or if rounded you would have 57kg
Hope this helps
Answer: Rate of change of Area of the triangle = 2.75cm~/min
Step-by-step explanation:
If the present height of the triangle is 22cm and the height increases by 5cm/min. It means the height was 2cm four minutes earlier: 5cm for 1st min + 5cm for 2nd min + 5cm for 3rd min + 5cm for 4th min = 20cm after 4min.
Therefore height equals 22 - 20 = 2cm four minutes earlier.
Using the same four minutes for the base. Since the base shrinks at 1cm/min, for the base to shrink to 10cm it means it was 14cm four minutes earlier.
The Area of a triangle is given by
A = 1/2 × base × height
Therefore Area= 1/2× 10×22 = 110cm~
Since it took four minutes to get to this area, the rate of change of the area will be 110÷4 = 2.75cm~/min
