Round off 278.785 to the nearest hundredth

Round off 278.785 to the nearest hundredth

The correct answer is: $278.79$

Explanation

We are rounding $278.785$ to the nearest hundredth (two decimal places). The hundredths digit is $8$ and the digit to its right (the thousandths) is $5$, so we round the hundredths up by $1$.

Steps:

  1. Identify digits: tenths $=7$, hundredths $=8$, thousandths $=5$.
  2. Rounding rule: if the digit right of the hundredth is $5$ or greater, increase the hundredth by $1$.
  3. Apply the rule: $278.785$ → hundredths $8$ becomes $9$ → $$278.785\approx278.79$$

Therefore, $278.785$ rounded to the nearest hundredth is $278.79$.

Name ___________________________ Section ___________________________ EXERCISE 29 U.S. Geological Survey Topographic Maps EXERCISE 29 PROBLEMS—PART I The following questions are based on the lower right (southeast) corner of the “Greasewood Spring, Arizona,” quadrangle (Maps T-18 and T-19 shown in color in the back of the Lab Manual): 1. What is the contour interval of the map? __________ feet 2. What is the difference in elevation between index contours? __________ feet 3. What is the elevation of the highest contour line at the top of the eastern Twin Butte? __________ feet 4. What do the dashed blue lines represent? _______________________________________ 5. What do the gray lines around and between the Twin Buttes represent? _______________________________________ 6. What is the name of the adjoining quadrangle to the south? _______________________________________ 7. The latitude of the upper right (northeast) corner of the map is 35°30′ N, while the longitude of the lower left (southwest) corner of the map is 110°00′ W. Why is this called a “7.5 minute” topographic map? (Hint: What is “minute” referring to?) 8. At the time this quadrangle was printed, what was the difference (in degrees) between true north and magnetic north for this map? __________ degrees 9. On all three graphic scales for the map, “0” is not at the far left. Explain the reason for this. 10. Using the graphic map scales, determine the maximum width of the eastern Twin Butte (use the 6100′ contour to be the outer edge of the butte). __________ feet __________ kilometers 205

Q6.1. If there is NO VARIATION in shell thickness within a population of snails, and no mutations occur, what happens to shell thickness in response to crab predation? ○ Shell thickness does not evolve in the population. ○ Shell thickness evolves for some snails in the population. ○ Shell thickness increases for all snails in the population. ○ Average shell thickness in the population evolves over several generations. Submit Q6.2. If there is NO SELECTIVE SURVIVAL based on shell thickness within a population of snails, what happens to shell thickness in response to crab predation? ○ The average shell thickness increases within each generation, but there is no change in shell thickness from generation to generation. ○ There is evolution by natural selection of shell thickness, and average shell thickness increases every generation. ○ There may be evolution of shell thickness, but not through natural selection and not necessarily toward thicker shells. ○ There is no change in shell thickness within the population. Submit Q6.3. If mutations arise that affect shell thickness within a snail population, then with crabs present, those mutations: ○ Will result in offspring having thicker shells than their parents. ○ Will result in offspring having thicker or thinner shells than their parents. ○ Will happen because the parents choose to give them to their offspring. ○ Will occur because crabs are present and snails need protection against predation.
