Answer:
36.50$
Step-by-step explanation:
The power of the light bulb in this problem is
P = 100 W = 0.1 kW
And the light bulb is operated for a time of
t = 10 hours
per day.
The light bulb is operated over 1 year (365 days), so the number of hours of operation is:
So the total energy consumed by the light bulb is
We know that the cost of operation is
p = 10 cents/kWh
Therefore, the total cost will be:
So, 3650 cents, or 36.50$.
An inequality can be formed by simply translating the problem statement to numerical expressions.
From the problem we know that
added with 
hours should be equal or greater than 
(helpful insight from the keyword "at least"). Therefore, it's inequality would look like:
(>= is used instead of ≥ for constraints in formatting)
The inequality above best models the situation.
From the problem we know that
The inequality above best models the situation.

Step-by-step explanation:
Given:
In ΔLMN and ΔXYZ,
To find: criteria that needs to be shown to prove ΔLMN ΔXYZ using SAS similarity theorem
Solution:
According to SAS Similarity Theorem, if two sides in one triangle are proportional to two sides in another triangle and the included angle between the sides are congruent, then the two triangles are said to be similar.
In ΔLMN and ΔXYZ,
So, ΔLMN ΔXYZ by SAS similarity theorem if
