Answer:
<h3>No it is not in scientific notation</h3>
Step-by-step explanation:
The standard form of a scientific notation is expressed as:
A * 10^n where;
A is any number from between 1 and 10
Given the expression 33.4 × 10^ − 2
Comparing with the general formula, you will see that A = 33.2
Since the value of A does not fall between 1 and 10, hence the expression 33.4 × 10^-2 is not a scientific notation

Answer:
obtuse angle
Step-by-step explanation:
Answer:
The measure of an interior angle of a regular 15-gon is 120°.
Step-by-step explanation:
We need to determine the measure of the size of an interior angle of a regular 15-gon having 15 sides.
Thus,
The number of sides n = 15
Hence,
Using the formula to determine the measure of an interior angle of a regular 15-gon is given by
(n - 2) × 180° = n × interior angle
substitute n = 15
(15 - 2) × 180 = 15 × interior angle
13 × 180 = 15 × interior angle
Interior angle = (10 × 180) / 15
= 1800 / 15
= 120°
Therefore, the measure of an interior angle of a regular 15-gon is 120°.
Answer:
11/12
Step-by-step explanation:
(1 1/10)/(1 1/5) = 1.1/1.2 = 11/12
__
You can also work this using improper fractions:
(1 1/10)/(1 1/5) = (11/10)/(6/5) = 11/10×5/6 = (11×5)/(6×10)
= (11×5)/(6×2×5) = 11/(6×2) = 11/12
