On the graph, it shows that the shortest meeting has lasted for 1/4 of an hour. An hour has 60 mins, you know it the shortest will be 15 minutes.
If its for any other number that you do not know, you can list as a proportion:
1/4 = x/60 (1 and x are on the top of the fractions)
Cross multiply: 1 * 60 = 60
Then divide by the number on the opposite corner of x: 60/4
x = 15
Answer:
Step-by-step explanation:
The answer would be "both groups show about the same average time"
Answer: 56.64%
Step-by-step explanation:
Given: Previous amount of flour = 2.26 kilograms
By the end of the baking session, amount of flour = 0.98 kilograms
Decrease in amount = 2.26-0.98 = 1.28 kilograms
Percent decrese = 

Hence, the percent decrease in the amount of flour = 56.64%
Imagine each horizontal line as 180 degrees. So if your angle measure on the top right is 81 the other side of that will be 99 degrees and then you can apply vertical angles. Since angle two is a vertical angle to the degree measure of 81 it is also 81. Which means angle three is equal to angle 1, which is 99 degrees. Now since the horizontal lines are parallel the same angle measure will apply to angles 4,5,6, and 7
Final answer angles 1,3,4,7 are 99 degrees
And angles 2,5,6 are 81 degrees
