Answer:16x?
Step-by-step explanation:
1. Percent error is
The guess is 15.5mi, and the actual distance is 14.5 mi.
Percent error is
2. The cost will be $31.95*(1+0.075) = $34.35
The 1 represents 100% of the original amount of $31.95, and now we add 7.5% (0.075) to the 100%. In other words we multiply $31.95 by 107.5%.
3. His commission will be $165 out of $4125, or $165/$4215 = 0.039 = 3.9%
4. The principal (amount of money you start with) is $12000, and the interest rate is 15% of that.
15% of $1800 = 0.15*$12000 = $1800
12 different combinations because 4 times 3 equals 12.
If you want to find cosP , since angles Z and P are 2 complementary angles then cosZ is the same as cosP so you say the cosP=sinZ=4/5 (property of 2 complement angles in a right triangle)
Since there is no info on how many salads were sold all together it would have to be 12. That is all the info you could give us..sorry if that doesnt help :(
