Answer:
B. 0 ≤ x ≤ 6
Step-by-step explanation:
The horizontal grid lines are 10 °C apart, so 45 °C corresponds to a vertical position halfway between the 4th grid line and the one marked 50.
The graph intersects that position at the 2nd vertical grid line. The vertical grid lines are 3 minutes apart, so the 2nd grid line represents 6 minutes.
If Peter conducted the experiment from its start until the temperature reached 45 °C, he conducted it over a period of 0 to 6 minutes, inclusive:
0 ≤ x ≤ 6
Answer:
C
Step-by-step explanation:
2x larger since 14x6.5=91 and 7x6.5=45.5
91/45.5=2
The least common multiple would be 56 because that is the lowest number that they both can divide into
