Well you would have to round this 5 and above goes up. Since 1 is lower than 5 that would leave you at 6.37. 7 rounds up so that would change to 6.4. Lastly 4 would round down, So that would leave you with 6. Now 6 is the simplest form but if your looking for rounded to the nearest tenth the answer would be 6.4. If your looking for rounded to the nearest 100th place 6.37. But over all simplest form is 6.
4.the dot would be on 1 1/2 and the x would be pointing toward the negative numbers
The time duration between 9:30 AM and 12:00 PM is 2.5 hours.
From the graph, we want the diameter, d, to be 1 cm when the time, t, is 2.5 hours.
Graph A yields d = 1.0 when t = 2.5. CORRECT
Graph B yields about d = 0.6 when t = 2.5. INCORRECT
Graph C yields about d = 0.48 when t = 2.5 INCORRECT
