Answer:
On Wednesday
Step-by-step explanation:
In this question, We have Alana practicing for three days. We now need to know in which of the days has she practiced closest to 2 hours. Hence, what we are to do here is simply find which of the practicing hours is nearest to 2hours.
The best thing to do here is to work with minutes. Hence whatsoever fraction we are having would be worked with based on minutes. Let’s do this!
On Monday, she practiced 11/4 hours. This means she practiced 11/4 * 60 minutes = 165 minutes
On Tuesday, practice was for 19/8 hours. This means she had practiced for 19/8 *60 = 142.5 minutes
Lastly, on Wednesday, her practice time was 2.6 hours and that is 2.6 * 60 = 156 minutes
Kindly note that 2 hours is same as 120 minutes. We just need to know which of these minutes is closest to 120 minutes. From what we have, 142.5 is the closest.
This means that her practice on Wednesday is the closest to two hours.
Answer:
the angles are 80 degrees and 40 degrees
Step-by-step explanation:
The sum of two opposite interior angles equal to the exterior opposite angle.
so;
4x + 2x = 120
x = 120 / 6
x = 20
4x = 80
2x = 40
The mean (or average) for the data set is 67.428
