Answer: The answer is 1833 heads and 11 hours, 11 minutes.
Step-by-step explanation: Given that the Magic Dragon has 2013 heads. The brave Leo is cutting off the Dragon's heads at a speed of 5 heads per minute. But, the Dragon's heads are growing back at a speed of 2 heads per minute.
So, the number of heads of Dragon that are decreasing per minute = 3.
Therefore, after 1 hour, i.e., 60 minutes, The number of heads of the Dragon
= 2013 - 60 × 3 = 2013 - 180 = 1833 heads.
Now, the fight will last until all the heads of the Dragon are cut. Let the fight lasts for 'x' minutes, then
Hence the fight lasts for 671 minutes, i.e., 11 hours and 11 minutes.
Thus, the Dragon will have 1833 heads after 1 hour and the fight will last for 11 hour and 11 minutes.
Answer:
40.2 Yards
Step-by-step explanation:
To find the diagonal length of the orchard, we need to use the Pythagorean Theorem. The formula of the Pythagorean Theorem is:
c²= a² + b²
a = 36 Yards
b = 18 Yards
Now let's plug in our values to the formula.
c² = a² + b²
c² = 36² + 18²
c² = 1296 + 324
c² = 1620
Now to find the value of c we need to get the square root of both sides.
c = 40.2
So the diagonal length of Mr. Richard's orchard is 40.2 Yards.
