The constant of proportionality is the number with the letter x.
The number with chicken in the above problem is 1/2
The answer is 1/2
Answer: If you take 4 times 6 you get 24, so take 3*6 to get an 18-foot shadow. 4:3=24:18. I hope this helps. I'm not sure what your choices are, though.
3 3/4 inches are equivalent to 3.75 inches:3 3/4 = 3.75. Divide 45 inches by 3.75 to see how many boards are needed: 45 / 3.75 = 12. To check: 3.75 x 12 = 45 inches. So, 12 boards are needed.
Answer:
The correct answer is option B
Step-by-step explanation:
The general form of inverse variation between the variables x and y is as following:
where c is constant
option A : y = x/12 ⇒ x = 12y (wrong option)
option B : y = 12/x ⇒ y * x = 12 (correct option) and c will be equal 12
option C : y = x + 12 ⇒ not similar to the general form (wrong option)
option D : y = 12x (wrong option)
So, the correct option is B
