Brianna is crocheting a scarf as a birthday present for her sister. She started the scarf yesterday and needs to finish it today
before her sister's birthday party. This table shows the relationship between the amount of time (in minutes) Brianna spends crocheting today, x, and the total length of the scarf (in inches), y.
x (minutes) y (inches)
10 19
50 23
60 24
80 26
According to the values in the table, do x and y have a proportional relationship?
The table says Brianna crocheted 19 inches in 10 minutes. If the relation were proportional, Brianna would have crocheted 5×19 = 95 inches in 5×10 = 50 minutes. Her actual length is only 23 inches, so length is not proportional to time.
The answer is 44 The angles are supplementary meaning they add up to 180 degrees, so you subtract the 4 and get 176 then divide by 4 for the four x’s hope this helps
