Solution:

<u>A few changes were made:</u>

  • 4 as 4.00.
  • 0.3 as 0.30

<u>New equation:</u>

  • 4 + 0.3 + 0.09 = 4.00 + 0.30 + 0.09

<u>Solving the equation:</u>

  • 4.00 + 0.30 + 0.09
  • => 4.39 (Refer to image for work)

Answer:

B)

Step-by-step explanation:

4 + 0.3 + 0.09 = 4.39

standard form is written in the form of a \times 10^n, where a is a number bigger than or equal to 1 and less than 10.

Therefore, 4.39 written in standard form is \mathsf{4.39 \times 10^0}

Answer:

95

Step-by-step explanation:

you first find out the angles mn and mt.

Since ns and ms are the same, we know ms is 35 degrees.

mt is 50, so we subtract 50 and 35 from 180, which is the degree of m.

so the answer is 95 degrees.
