Answer 1

D and we all know that's a think through math screen and question

;D

Answer 2

Answer: At this rate, it would take less than 10 minutes for the temperature of the liquid to rise 52° C.

Step-by-step explanation:

Given: The graph shows the temperature of a liquid that is being heated during an experiment.

From the graph , we can see the the line is going up from left to the right.

Therefore, the temperature of liquid is increasing at a constant rate [as the line is at same distance from temperature axis and time axis].

In 6.5 minutes the rise in temperature= 26°C

Therefore in 1 minute , the change in temperature= $\frac{26}{6.5}=4^{\circ}$

Now in quarter hour(15 minute), temperature=$4\times15=60^{\circ}C$

To rise in temperature by 52°C, time taken=$\frac{52}{4}=13\ minutes$, which is greater than 10 minutes.

Thus fourth statement is incorrect about the graph.
