Question

Evaluate the expression when t = 0.2.

300t2−0.5÷t

Enter your answer as a decimal in the box.

Answer 1

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

Answer 2

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.
