Answer:
2:5
Step-by-step explanation:
The ratio of a dimension on Figure B to the corresponding dimension on Figure A is ...
4:10 = 8.6:21.5 = 10:25 = 2:5 or 1:2.5
___
In such problems, it isn't clear if the desired answer is the ratio of two integers or if it is 1 : (something). We have expressed it both ways, so you can use the answer that matches your requirement.
<u>Answer</u>
D
<u>Explanation</u>
9⁽¹/²⁾² = (9⁽¹/²⁾)²
= 9¹/² × 9¹/² (Since the base are the same, we can add the power.)
= 9⁽¹/² ⁺¹/²⁾
= 9 ¹
= 9
The correct simplification is D.
