Answer: 1.3 (Estimated)
Work: To find that out, I divided 4 minutes by 3 laps, and that's 1.333... In which I rounded that to 1.3.
.25*3=.75
.375*2=.75
.5*2=2.0
.625*2=1.25
.75*3=2.25
.875*2=1.75
1*2=2
1.25*2=2.5
1.5*2=3
1.5+2=3.5
1.25+2.25=3.5+3.5=7
3.5+1.75=5.25
5.25+4.5=9.75
9.75+3=12.75
answer = 12.75in^2
Given:
First, just leave the negative sign at the side. You will deal with that later. For now, you focus on solving on the square root of 25. The square root of 25 is a number that when multiplied with itself, equals to 25.
For example, 4x4=16. So, the square root of 16 is 4.
Now, for 25, the answer would be 5. Since 5x5 = 25.
Then, you take the negative sign with the 5. The answer would be
-5.

Answer:
2.25
Step-by-step explanation:
The number 2.25 is already in standard form.
___
In the US (and other places), "standard form" is an ordinary decimal number, with the integer part to the left of the decimal point and the fractional part to the right of the decimal point: 2.25.
In the UK (and other places), "standard form" is a number written in scientific notation with a mantissa consisting of the leading non-zero digit to the left of the decimal point, the remaining significant digits to the right of the decimal point, and a multiplier that is 10 to the power appropriate to the place value of the leading digit. When the multiplier is 1, we need not write it.
2.25 = 2.25×10⁰ (full form) = 2.25 (with superfluous 10⁰ removed)
