Answer:
Diameter = 2 × inches
Step-by-step explanation:
Given the diameter of the smallest visible particle, 0.0002 inches, we can express this into the following scientific notation: 2 × inches.
In expressing decimal forms into scientific notation, the goal is to move the decimal point towards the right, until there is only one non-zero digit remaining towards the left-side of the decimal point. In this case, it will take 4 units towards the right of the sole non-zero digit, which is 2. Moving the decimal point towards the <u>right</u> means that 10 will have a <em>negative</em> exponent.
Therefore, the scientific notation of 0.0002 inches is 2 × inches.

Answer:
thats long just use calcukator
Supplementary angles add up to 180
so (2x + 3) + (3x + 2) = 180
.
<u>Solve x:</u>
2x + 3 + 3x + 2 = 180
5x + 5 = 180
5x = 175
x = 35
.
<u>Find the angles:</u>
One angle = (2x + 3) = 2(35) + 3 = 73°
Other angle = (3x + 2) = 3(35) + 2 = 107°
.
Answer: The two angles are 73° and 107°
