y = 9x + 55 because the 9x is the amount you get paid an hour, and to get to the 199 you need to include to rate at which you get paid, and add that to how much you already have saved.
Answer:
55 miles
Step-by-step explanation:
11 miles = 45 min
speed = distance/time
speed = 11/45
speed = 0.2444 miles/min
for 225 min, speed is same
distance = speed * time
= 11/45 * 225
=55 miles
You would divide 100/20 and get 5. then u would multiply 9 times 5 equals 45 then add a decimal to get ur answer 0.45
The value of tan3x must be greater than the value of cos3x, because it is subtractable by a lesser value.
We have that
cos(alfa)=0.2546
arc cos (0.2546)=75.2501---------- > 75.25°
the answer is 75.25°
