Answer:

  • 9.5

Solving the given expression.

We know that:

  • t = 0.2
  • Given expression: 300t² − 0.5 ÷ t

Now, let's solve the given expression.

  • 300t² − 0.5 ÷ t
  • => 300 x 0.2² − 0.5 ÷ 0.2
  • => 300 x (2/10 x 2/10) − (5/10 x 10/2)
  • => 300 x (4/100) − (5/2)
  • => 300 x 4/100 − 5/2
  • => 3 x 4 − 5/2
  • => 12 - 5/2
  • => 12 - 2.5
  • => 9.5

Hence, the solution is 9.5.

300 • ( 0.2 )^2 - ( 0.5 / 0.2 )

0.2 ^ 2 = 0.04

300 • 0.04 = 12

0.5 / 0.2 = 2.5

12 - 2.5 = 10 - .5

9.5
