Answer:
The speed of the balloon is 0.16 m/s.
Step-by-step explanation:
CD = 300 m
Let AD = x
AB = y
time, t = 3 min
Triangle, ADC
Triangle, BCD
So, y = 109.2 - 80.4 = 28.8 m
Speed = 28.8/180 = 0.16 m/s
Answer:
16.67%
Step-by-step explanation:
Step one:
given data
predicted value= 300 bottles
Actual value = 350 bottle
Required:
the % error
Step two:
%error= actual- predicted/predicted *100
%error= 350-300/300 *100
%error= 50/300 *100
%error= 0.166*100
%error= 16.67%
The answer is A, 651. You would first start by multiplying the number of students, 1,860, by 45%, or .45. You'd come out with the answer of 837. You would then add 837 and 372 together to get a sum of 1,209. Finally, you would subtract 1,209 from the total number of students, which was 1,860 and get an answer of 651. I hope this helped you understand how a problem like this should be worked out!
The sum of the 3 interior angles must be 180 degrees.
Thus, 42 + 4p + 2p = 180 degrees, or 6p = 138 degrees. Then p = 23 degrees.
