in a hypothetical thermometer, the freezing point of water is marked as -10 and the boiling point is marked at 70. What would be the reading if this thermometer is used to measure the temperature of 50 degree water?

40 degrees

60

To determine the reading on the thermometer if it is used to measure the temperature of 50-degree water, you need to consider the freezing and boiling points as reference points.

In this hypothetical thermometer, the freezing point of water is marked as -10 and the boiling point is marked at 70. To find the reading for 50-degree water, you need to determine the temperature scale being used.

Assuming a linear scale, you can calculate the difference between the freezing and boiling points (70 - (-10) = 80), which represents the range of temperatures from freezing to boiling.

Next, find the value that corresponds to 50 degrees within this range. To do this, divide the temperature difference (80) by the overall range (80).

50 / 80 = 0.625

This means that 50 degrees represents 0.625 of the overall temperature range.

Finally, multiply this ratio (0.625) by the corresponding range on the thermometer scale (70 - (-10) = 80) to obtain the reading on the thermometer for 50-degree water.

0.625 * 80 = 50

Therefore, the reading on the thermometer for 50-degree water would also be 50.
