The two equations are:
y=.17x+35.96
y=.12x+49.96
He would have to drive 280 miles for both of them to cost the same.
Your overall grade will go down. I'd try to ask your teacher if you can make them up.
Multiply the numbers
2(2/3)
2/1(2/3)= 4/3 = 1 1/3
Answer:
26.8°
Step-by-step explanation:
The cosine of an angle is the ratio of the adjacent side of the triangle in which the angle is formed to the hypotenuses side of the triangle. The cosine of the angle gives the ratio of these sides. However, the arc cosine of the ratio gives the angle measured in degrees.
If cos B = 0.8926
then arc cosine 0.8926 which may be expressed as cos-1 0.8926 will give the value of B.
B = cos-1 0.8926
= 26.8°
