Answer:
4.7 to nearest tenth.
Step-by-step explanation:
By Pythagoras:
8^2 = x^2 + 6.5^2
x^2 = 8^2 - 6.5^2
x^2 = 64 - 42.25 = 21.75
x = √21.75
= 4.6637
Answer:
Train A is 287 tons
Train B is 94 tons
Step-by-step explanation:
My method of solving it may have been a bit different from how you were taught. I divided 381 by 2 to give both trains an equal weight of 190.5 tons. I then divided the difference, 193, by 2 to get 96.5 tons. I subtracted the new difference from the weight of Train B and added it to train A. To double check, you can grab a calculator and see that their weights are equal to 381.
