Step-by-step explanation:
Answer:
2/3
Step-by-step explanation:
Since the length increases by 0.5 cm every second, after 8 seconds the length will increase by 4 cm. 12 + 8 + 12 + 8 = 40, and 40 - (16 + 16) = 8. 8/2 = 4, so the width is now 4. 16 * 4 = 64, and 12 * 8 = 96. 64/96 = 2/3.
1 times 10 is 10. 10 times 10 is 100. So for those 3 models, the base is 10. All grids relate to the base 10 number system, because from left to right, the shaded part is getting bigger (increasing) by multiplying by 10. Hope this helps!
