Answer:

1. Express 30°C to F

F = C × 9/5 + 32

= 30 × 9/5 + 32

270/5 + 32

54 + 32

= 86°F

Answer: 86°F

2. Express 75°F to °C

C = F - 32 × 5/9

= 75 - 32 × 5/9

43 × 5/9

215/9

= 23.889°C

Answer : 23.889°C

3. Express 95°F to kelvin

Since there is no conversion From F to K,we will convert first °F to °C to K.

Solution:

°F to °C

C = F - 32 × 5/9

= 95 - 32 × 5/9

63 × 5/9

315/9

= 35°C

°C to K

K = °C + 273.15

= 35 + 273.15

= 308.15 K

Answer: 308.15K

Sana nakatulong ^_^
