Answer:
m∠1 = 123°
Step-by-step explanation:
Since a straight line is always a supplementary angle, it equals 180°. To solve for the unknown angle, we can subtract the known angle from 180°.
180° - 57° = 123°
So m∠1 = 123°
Cost = $12,800
Time = 2 hours, 8 - 10 pm
Cost per hour = ($12800)/(2) = $6400 per hour
There are 60*660 = 3600 seconds per hour.
Therefore the cost per second is
($6400)/(3600 s) = $1.7778 per second = $1.78 per second (nearest cent)
Answer: $1.78 (nearest cent)
You can solve using the pythagorean theorem which is
a^2+b^2=c^2 where a and b are the legs and c is the hypotenuse in a right triangle.
12^2+x^2=24^2
144+x^2=576
x^2=432
x =20.78 (approximately)
Answer:
600 minus 28 w less-than-or-equal-to 300
Step-by-step explanation:
1.) 3x -4 <_ 2
Add 4 to both sides.
-4 + 4 = 0
2 + 4 = 6
3x <_ 6
Divide both sides by 3.
3x / 3 = x
6 / 3 = 2
x <_ 2 is your answer for the first inequality.
2.) 2x + 11 _> -1
Subtract 11 from both sides.
11 - 11 = 0
-1 -1 = -2
2x _> -12
Divide both sides by 2.
2x / 2 = x
-12 / 2 = -6
x _> -6 is your answer for the second inequality.
I hope this helps!
