We can use a pattern of the last two digits for power's of 11. 11,21,31,41,51,61,71,81,91,01 So every 10th power has 01 at the end, now we can count 5 more time to get to the tens digit being 5.
So the digit in the tens place is 5.
The number of sides is 8.
Based on looking at other problems similar to this, I think you meant 1/3 of the total load which means if we say t=800+x and t=4/3x then subtract the first equation from the second, we get 1/3x=800, or x=2400. Then to solve for t we add 800 to get t=3200.
So the greatest load the truck can carry is 3200 pounds.
Sure there can, if you make a square that has all vertices which touch the edge of the circle, then you have 4 chords in a circle already. So, yes.
Well, we can say it is (x+y)^2 which expanded is x^2+2xy+y^2. We can see in the original equation it is x^2 which is in our expanded equation and then 8x is 2xy in the expanded equation. This means that 2xy=8x, or y=4. This means the blank which is y^2 is 4^2 or 16.
So the constant is 16 and the equation is x^2+8x+16.
Yes, that was what was happening lol. Thx!
Now I realize that lol. I was confused on how I should write the sentence and ended up writing a sentence which, as you said, is contradicting itself.
Guest had done simple interest, which is why they got it wrong.
