Answer:
let say the number is x, then 30x÷100=78, x=260...from this we can calculate 95 percent of 260 which is equal to 247
Answer:
60 °
Step-by-step explanation:
Applying the law of sine we have the following:
160 / Sin B = 80 / Sin 30 °
We solve for B and we have:
160 / Sin B = 80 / 0.5
160 / Sin B = 160
Without B = 160/160
B = Arc Sin (1)
B = 90 °
Now to calculate the other angle (true
course) would be:
A = 180 ° - (B + C)
A = 180 ° - (90 ° + 30 °)
A = 60 °
That is to say that true course is 60 °
Answer:
Step-by-step explanation:
Needs to sell 24 more mugs to reach his goal
A = pi x r^2
A = pi x 8^2
A = pi x 64
A = 201.061..
A = 201cm^2 (3sf)
