You can find the answer by plugging in any of the multiple choice options into a,
when you square a number (^2), the result is always positive even if the number starts off negative,
-25 or 125 wouldn't work for this equation because the answer is too big
but when you plug -5 or 5 in you get the right answer, so the answer is c
Answer:
1.59 < 1.73 < 2.061 < 2.1
Step-by-step explanation:
Hello,
We know that 2 is higher than 1. So to pick the first ones we know it won't be the two numbers starting with a 2. We are left with two numbers : 1.73 and 1.59. <u>In this case we can multiply these two numbers by 100. We are allowed to do this only if we do it to all the numbers we are trying to figure out.</u> In this case, it is 1.73 and 1.59 (we are excluding the 2s). So we end up with : 173 and 159. This might help you. We obviously know that 173 is a larger number than 159.
So, we then proceed to the numbers starting with a 2. <u>In this case we can multiply both by 1,000 considering the fact that the number 2.061 has 3 digits after the dot.</u> This will make it easier for us. When we multiply both by 1,000 we end up with 2,061 and 2,100. We obviously know that 2,061 is smaller than 2,100.
I hope this helped

Well if Bob (represented by x) is three years older than Bill (y), the only one correct is x=y+3. Dividing by three wouldn't make sense (choice A), adding three more years onto Bob won't work (choice B), and multiplying Bob's age by three wouldn't work either (choice D). The answer is choice C.
x=y+3
All you have to do is divide 280 by 1.75
It'll therefore take 160 seconds to travel 280 feet
