We have that
cos(alfa)=0.2546
arc cos (0.2546)=75.2501---------- > 75.25°
the answer is 75.25°
The base price of the car is about $22,196 because:
x= major options package
10x + x = 24,416
*the 10x is the price of the car
This then simplifies to
11x = 24,416
use division.
The destination charge is not needed unless you want to check your answer. If you have to then you would do the same thing. The equation would be:
y= destination charge
5y + y = 24,416
Hope this helps.
12:32 is simply 3:8 but divided by 4 to both sides.
The domain is (-infinity, 6] I believe.
