Sidana [21]3 years ago
3 0

Answer:

18

Step-by-step explanation:

60% of 50 is 0.60x50=30

40% of 30 is 0.40x30=12

30-12=18

<u>So 60% of 50 is 18 greater than 40% of 30.</u>

At what temperature would the centigrade and Kelvin scales give similar readings<br>​
Serjik [45]

Answer:

The formulas for converting between degree Celsius and degree Fahrenheit are:

°F = (°C * 9/5) + 32

°C = (°F - 32) * 5/9

To find the temperature when both are equal, we use an old algebra trick and just set ºF = ºC and solve one of the equations.

°C = (°C * 9/5) + 32

°C - (°C * 9/5) = 32

-4/5 * °C = 32

°C = -32 * 5/4

°C = -40

°F = (°F * 9/5) + 32

°F - (°F * 9/5) = 32

-4/5 * °F = 32

°F = -32 * 5/4

°F = -40

So the temperature when both the Celsius and Fahrenheit scales are the same is -40 degrees

Have a nice day!!!
