Answer:
m<1= 120
Step-by-step explanation:
1. we know supplementary angles equals 180. the angle 130 is part of a supplementary angle so we can subtract it by 180 to see that missing angle.
2. we also know that all triangles three angles add up to 180. So if we add the number we know 70+50 (50 is from subtracting 130 from 180), Once we find that answer, we subtract it from 180 to find angle 2 which is 60 degrees
3. Last step, angle 2 is part os a supplementary angle in which the two angles add up to 180. So, subtracting 60 from 180 will get you the degree of the angel one which his 120 degrees.
Absolute value- the amount a number is away from zero. With this information, we can conclude,
|-12| = 12
|-15| = 15
The equation relating this should be linear since the increase in amount earned is constant throughout which is $24 per hour. The equation is in the form:
y = mx + b
where,
y = earning
m = slope or earning per hour = $24
x = total number of hours
b = y intercept or initial earning upon visit = $45
Hence,
y = 24x + 45
Since we are working at two separate work sites, therefore each site we must earn 810/2 = 405
So when y = 405:
405 = 24x + 45
x = 15 hours
So you must work 15 hours at each site, 30 in total.
I beleive the answer is C
