Which students, if any, have correctly identified a base and its corresponding height? which ones have not? explain what is incorrect.
(explain)!

The Explanation is below .

Step-by-step explanation:

a. )

Raul is correct because Height should always be Perpendicular

and Raul has drawn Height 'h' Perpendicular to the corresponding Base 'b'.

b. )

Mark is incorrect because Height drawn is NOT Perpendicular.

c. )

Kiki is incorrect because the corresponding base is incorrect, Height drawn is correct that is Perpendicular.

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

the least common denominator is 40
