It's stays the same so the answer is 9,138
Answer:
the greatest common factor is 50
Step-by-step explanation:
200 = 2 × 2 × 2 × 5 × 5 Find the prime factorization of 1650
1650 = 2 × 3 × 5 × 5 × 11 To find the GCF, multiply all the prime factors common to both numbers:
Therefore, GCF = 2 × 5 × 5GCF = 50
There are a couple of ways to think about this.
1) Weight the speed by the time and compute the weighted average.
(60*2.5 + 75*1.5)/(2.5 + 1.5) = 65.625
Her average rate of speed is 65.625 mph.
2) Consider distance and time.
distance = speed * time
distance₁ = speed₁ * time₁
distance₂ = speed₂ * time₂
total distance = distance₁ + distance₂
total time = time₁ + time₂
And the average speed is given by
average speed = (total distance)/(total time)
Using the above formulas, we have
distance₁ = 60 mi/h * 2.5 h = 150 mi
distance₂ = 75 mi/h * 1.5 h = 112.5 mi
total distance = 150 mi + 112.5 mi = 262.5 mi
total time = 2.5 h + 1.5 h = 4.0 h
average speed = (262.5 mi) / (4.0 h) = 65.625 mi/h
Bette's average rate of speed is 65.625 mph.
Answer:
BC, CA, AB
Step-by-step explanation:
the measure of each angle is super important, bc you use it to compare the lengths of each side in this problem. the bigger the angle, the bigger the opposite side is. so, if you were to draw a line from the angle measuring 83 degrees, it would go to side AB. since the angle measure is the largest out of the three angles, it makes AB the largest side.
hopefully that makes sense!! :)
