8. Convert 100°F into Celsius scale.
9. Change 8% into decimals,
10. Find the value of 20% of 2500.​

Answer 1

Answer:

(6) First three digit numbers are 10,11 and 12

So average = 10 + 11 + 12 / 3

= 33/3

= 11

(7) F = 9/5 × C + 32

= 9/5 × 55 + 32

= 99 + 32

= 122°F

(8) C = 5/9[F - 32]

= 5/9 ( 100 - 32 )

= 5/9 (68)

= 37.77°C

(9) 8% = 8/100

= 0.08

(10) 20% of 2500 = 20/100 × 2500

= 500
