Answer:
a. Earnings of Enguun for 12 hours this month (G)
G = 204 dollars
b. Earnings of Enguun for 19.5 hours last month (G)
G = 331.5 dollars
Step-by-step explanation:
Nomenclature
G: Total earnings of Enguun in dollars
E: Enguun's earnings for 1 hour of tutoring (dollars/hour)
n: number of hours that Enguun tutored per month (hour/month)
Formula
G = E*n
E = $17 per hour = 17 dollars/hour
Problem development
a. Earnings of Enguun for 12 hours this month
n = 12 hours
G = E*n
: We eliminate hours
G = 204 dollars
b. Earnings of Enguun for 19.5 hours last month
G = E*n
G = 17 * 19.5
G = 331.5 dollars
Answer:
500.
Step-by-step explanation:
(1 * 10^6) / (2 * 10^3)
= 1/2 * 10^6/10^3
= 0.5 * 10^3
= 5 * 10^2
= 500.

Answer:
179/495
Step-by-step explanation:
When the repeating decimal starts at the decimal point, the repeating digits can be turned into a fraction by putting them over the same number of 9s. That is, 0.61616161... is equivalent to 61/99.
Here, the repeating part is 1/10 that value, so is 61/990. This is added to the non-repeating part, which is 0.3 = 3/10.
Then the entire decimal is ...
0.361_61 = 3/10 + 61/990 = (297 +61)/990 = 358/990 = 179/495
Answer: Choice C)
g(x) = -|2x|
You get this answer by simply sticking a negative out front of the original function. In other words, g(x) = -f(x) or more technically, g(x) = -1*f(x).
The negative will flip every y coordinate from positive to negative (or vice versa)
You'll also use the idea that |2x| = 2|x|. The two can be pulled out since we can say |x*y| = |x|*|y|
So |2*x| = |2|*|x| = 2|x|
