Answer:
Step-by-step explanation:
You can fill in the space between 0 and 1/2 with 3 ovals that are of length 1/6.
This tells you that 1/2 ÷ 1/6 = 3.
Answer:
5sqrt3
Step-by-step explanation:
Using the pythagorean theorem, we have a^2+4^2=9^2
a^2 + 16 = 81
a^2 = 75.
a = sqrt75.
75 = 25*3. 25 is a perfect square, so sqrt75 = 5sqrt3
Answer:
B
Step-by-step explanation:
Yes, both of these ratios are proportional. You could either plug it into an equation and solve it, or do like I did and divide. If you divide 16 by 12, you get 0.75. If You divide 24 by 18, you also get 0.75, therefore they are equal. The reason why I divided by the numbers that I did is because you're trying to figure out how much it increased and if it was equivalent. They increased 0.75% of their size that they started with. I hope this helps!
