The theorem was known to the Babylonians and Indians long before Pythagoras's time. However it is thought That the Greek Pythagoras was the first to construct a proof of the theorem, that,s why it was named after him.
Answer:
340 sheep.
Step-by-step explanation:
There is a decrease of 640 - 576 = 64 sheep in the first year.
This is 1/10 of the previous year, so the number in year 2 is 0.90 of the number of sheep in year 1, so a model for this could be:
640(0.90)^x where x is the year.
So after 6 years the estimate would be 640 *(0.90)^6
= 340 sheep.

Answer:
10 liters.
Step-by-step explanation:
Let the volume of 2% acid be x liters.
Then the volume of the 8% solution will be (x + 30) liters.
Work in amounts of pure acid: amount of acid in the 10% solution = 30 * 0.1
= 3. So we have the equation:
0.02x + 3 = 0.08(x + 30)
0.08x - 0.02x = 3 - 0.08*30
0.06x = 0.6
x = 10
So the answer is 10 liter of the 2% solution.
