Answer:
66170 mm
Step-by-step explanation:
0.06617 km * 1000 km/m * 1000 m/mm = 66170 mm
Given:
The table of values is
Number of Students : 7 14 21 28
Number of Textbooks : 35 70 105 140
To find:
The rate of change and showing that the ratios of the two quantities are proportional and equivalent to the unit rate.
Solution:
The ratio of number of textbooks to number of students are
All the ratios of the two quantities are proportional and equivalent to the unit rate.
Let y be the number of textbooks and x be the number of students, then
Here, k=5.
Hence the rate of change is constant that is 5.
Answer:
x = 110°, y = 110°
Step-by-step explanation:
y = 110° ( vertical to 110° )
x = 110° ( alternate angle to y )
