The richmond family restaurant has several types of hamburgers on its menu. the more hamburgers their customers order, the more hamburger buns they will use.

h = the number of hamburgers ordered
b = the number of hamburger buns used

which of the variables is independent and which is dependent?

INDEPENDENT  variable  : h = the number of hamburgers ordered

DEPENDENT variable :   b = the number of hamburger buns used  

Step-by-step explanation:

Independent Variables: The type of variables whose change is NOT DEPENDENT on the change of other variables are known to be independent variable.

Dependent Variables: The type of variables whose change is DEPENDENT on the change of other variables are known to be independent variable.

Now here:

h = the number of hamburgers ordered

b = the number of hamburger buns used

The number of buns used depend upon the number on the buns ordered.

More buns Ordered ⇒  More buns Used

⇒  Used buns is dependent upon the order.

Hence, h = the number of hamburgers ordered  is INDEPENDENT.

b = the number of hamburger buns used    is DEPENDENT variable.

the correct answer is a.) bc< mn 5 stars if this you : )

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
