Date 1. Melissa gives vitamins to her adult dogs. The recommended dosage is 2 teaspoons per

weighs 90 pounds. How many teaspoons of vitamins are needed for Buster?

Melissa needs to give buster 4 and a half vitamins

Step-by-step explanation:

if 2 table spoons is recommended for 20 pounds and buster weighs 90 pounds, to find how much to give buster you need to divide busters weight with the recommended weight to find out how many tablespoons to give him.

90 ÷20= 4.5

buster needs 4.5 tablespoons of vitamins for his weight.

english, cause i can’t you

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
