What is the greatest common factor for 1650 and 200
enyata [817]

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

bette drives at 60 mph for 2 and a half hours and 75 mph for 1 and a half hours. What is her average rate of speed?
andrezito [222]
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.

Help please !!!!!!!xxxxx
vladimir1956 [14]

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!! :)
