Answer:
155
Step-by-step explanation:
its the only angle larger than 90 degrees and 90 degrees is a right angle
Answer: A. y = 4x + 3 is the correct answer.
Step-by-step explanation:
h = -490t² + 1470t
When h = 980:
980 = -490t² + 1470t
Simplifying:
0 = -490t² + 1470t - 980
0 = t² - 3t + 2
Factoring:
0 = (t - 1) (t - 2)
t = 1, 2
There are two solutions because the rocket first reaches the height of 980 cm as it's going up at 1 second, then it reaches that height again as it's coming down at 2 seconds.
I believe that the question is asking if there is a large variation between the results or not, as it asks if the births are with equal frequency. Since the largest is 72 and the smallest is 43 (for a 29 number difference), it doesn't seem like they are with the same frequency
Answer:
12.
Step-by-step explanation:
4 divides exactly into 12 so the LCM = 12.
