Answer:
2cm³
Step-by-step explanation:
Answer:
d) not proportional
Step-by-step explanation:
the rate of change between the first two pairs of x-and-y values is 12/3, between the second pair it is 21/3, and 15/3 between the last pair
4, 7, and 5 are all different values so there is not one constant of proportionality
Answer:
x=-8
Step-by-step explanation:
We are solving for the variable, x, so let us <u>isolate</u> all terms of x. Let us start by moving the numerical value 2 to the right side, thereby <u>isolating</u> the term 2x on the left:
2x= -18+2
2x=-16
So close! Let us divide both sides by 2 now:
x= -8

<span>It is not clear whether the populations are proportional to the radii or to the areas, but I seem they are proportional to the areas, which is to say to the square of the radii. So China's population % should be (17%)(3.4/3.2)^2 = sorry I don't bring a calculator right now. But you can solve it easily.</span>
