Please help me with these questions
Any help will be appreciated.

Step-by-step explanation:

28) Perimeter = 10 + 2 + (10 -2) + 3 + (8-2) + 1 + 8 + (1+3+2)

                       = 10 + 2 +  8 + 3 + 6 + 1 + 8 + 6

                        = 44 cm

29) Area = Area of upper block + area of middle block + area of the down block

= (10 * 2) + (2*3) + (1*8)

= 20 + 6 + 8

= 34 cm²

the answer is b

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
