Can anyone tell me examples of someone who is considered a modern-day social critic?

If you have 1 sack of cotton (which is expected to float on water) and were asked to measure the volume, what will you do?

help me finish the sentence? "I enjoy writing and the privilege of having me intern here is a _______?"

1. A boat traveled 210 miles downstream and back. The trip downstream took 10 hours, the trip back took 70 hours. What is the speed of the boat in still water? What is the speed of the current? 2. Flying to Kampala with a tailwind a plan averaged 158km/h....

how come if I do: x+y=158 x-y=112 and then i subtract them: 2y=46 -> y=23 why do I get the speed of plane as 23?

oh okay thank you so much! i also have another question: does it matter whether we add or subtract simultaneous equations? do we have to either add or subtract or are both fine?

oh okay thanks! I got 135 not 155... but does that apply everytime or is that just a shortcut type of thing? it's not wrong if I subtract x+y=158 and x-y=112 right?

Well, obviously the speed of the plane must be greater than the speed of the wind, so in x-y = 112 x must be the plane's speed and y the wind's speed so sub y = 23 into x+y = 158 x+23=158 x = 155 ^that's what you said.. you wrote 155 not me..?

1 000 000 more than 746 000

underestimate

60

Thanks Earl, 3/3 on connexus!

You forgot the negative at the beginning in part B. Everything else is correct

Ilove you to
