Trace metals in drinking water affect the flavor and an unusually high concentration can pose a health hazard. We obtain the fol

lowing data for 9 glasses of water. Each glass contained the same amount of water. We look at the zinc concentration (mg/L) in bottom water and the zinc concentration in surface water for each glass. It is fine to round any standard deviations to 2 decimals. Glass 1 2 3 4 5 6 7 8 9 Bottom Water .48 .32 .62 .58 .76 .77 .70 .64 .52 Surface Water .42 .24 .39 .41 .61 .61 .63 .52 .41

Find the standard equation of a circle that passes through the point (−1, 1) with center (2, 3).
Firlakuza [10]
The equation of a circle is
  (x-h)² + (y-k)² = r²
for center (h, k) and radius r. Of course, the radius can be computed by putting the point in the equation.
  (x-2)² + (y-3)² = (-1-2)² + (1-3)² = 9+4 = 13

The standard equation of the circle is (x-2)² + (y-3)² = 13.

Ramon uses models to compare two decimial he says 0.09 greater than 0.1 because 9>1 which of these explain ramon's mistake
Shalnov [3]

Answer:

Ramon's mistake was that he used whole numbers in comparison to decimals, which is not an accurate way to solve. Think about it this way, 0.1 is the tens place, 0.01 is the hundreds place. Which would be greater 100% of the time? The hundreds place, in decimal terms, the hundredths.

0.09 is greater than 0.1

If it takes Tim 2 hours to drive to the campground and it takes 3 times more long then driving to the campground. Then all you have to do is 3 multiplied by 2 and then your answer would be 6 hours.
