On the fahrenheit scale the difference between the freezing and boiling point of water is 180 degrees. on the celsius scale the difference between the freezing and boiling point of water is 100 degrees. if the temperature in the us increased by ten degrees fahrenheit and on the same day in the uk the temperature increased by ten degrees celsius, which location got warmer?

Step-by-step explanation:

Given that On the Fahrenheit scale the difference between the freezing and boiling point of water is 180 degrees. On the Celsius scale the difference between the freezing and boiling point of water is 100 degrees.

This implies that smaller differences make a large impact on warmth for celcius than fahrenheit.

THis is because 100 degrees increase is sufficient to boil water but 180 degrees is required for fahrenheit

So for same 10 degrees change celcius will have more effect to warm.

UK would be more warmer since increase in 10 degree celcius is equivalent to 18 degree fahrenheit.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
