Rounded to the nearest ten thousand, 15,677 would become 20,000. To be
rounded down to 10,000, the original number would need to be 14,999 or
lower.
All u have to do is find what variable will make each statement true, I'll do one so u would get what I mean,
61. x + 13.5 < 19, this could be anything under 19 since it's supposed to be greater, I chose 5 + 13.5 < 19 which is 18.5 < 19
The number goes from 13.5 to 19 you could do it like decimals, start it from 13 then go on like this, 13,13.5,14,14.5,15,15.5,16,16.5,17,17.5,18,18.5,& 19.
Original height of tree = (x+5) m
In triangle ABC x square = 5 square + 12 square
X square = 25+144
X square = 169
X = 13
Thus the original height of the tree was 13+15 = 18m
For the first question, yes, they are similar. Each of the corresponding sides has a ratio of 4:1 from the first polygon to the second, meaning they are similar. For the second question, the ratio is 1.6:1, and if we multiply the 10 on the bottom polygon by 1.6, we get 16, which is the answer.
For real though, I’m hoping you don’t get sent back there. I’m assuming you dislike it there, so good luck with your course. I’m here to help if you need it.
