Answer:
90%
Step-by-step explanation:
If you are going to find out the percent of the car that do not have 4 wheel drive, you take the total amount of car that passed though the stoplight which is 100% . You take this 100% and then subtract the 10% to get the final answer 90%. 90% of the cars do not have 4 wheel drive.
Answer: Mr Brust snored a total of 19,840 times last summer
Step-by-step explanation:
Mr Brust snores in the ratio of 1 nap : 320 snores or 1 nap = 320 snores
Given that he took a nap everyday, last summer We have that .
For the month of July,
he had 31 naps( 31 days are in July)
Number of snores he made =31 x 320=9,920 snores
For the month of August
he also took 31 naps ( 31 days are in AugusT)
Number of snores he made = 31 x 320=9,920 snores
Therefore Mr Brust snored a total of 9,920+ 9,920 =19,840 times
Given expression is sin(45)sin(15)
this expression best matches with left side of the formula:
2 sin(A) sin(B)= cos(A-B) - cos(A+B)
so we can plug given angles 45 and 15 there
2 sin(45) sin(15)= cos(45-15) - cos(45+15)
2 sin(45) sin(15)= cos(30) - cos(60)
sin(45) sin(15)= [cos(30) - cos(60)]/2
We are getting negative sign and cos in the solution while none of the given choices have same situation so answer will be none of them.
-----------
For cos(75)-cos(15), we will use formula:
Now plug the given angles
Hence choice B is correct.
