That’s your final answer :)
Answer:
Step-by-step explanation: the inequality itself would be like this
8<x (there should be a line under the “<“ i just can’t make it) then you want to draw a vertical line on the x value 8 and shade to the right of the line.
Answer:
Step-by-step explanation:
Use the distributive property of equality to multiply and get:
Simplify by combining like terms to get your end result:
The ratio of the areas is the ratio of the squares of the sides ( which is 10:15 or 2:3) so the answer is
2^2 : 3^2 = 4:9.
The ratio of the perimeters = ratio of corresponding side = 2:3.
<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>
