Answer:
Imperfect substitutes
explanation:
The choices above are not perfect substitutes, meaning they can not be perfectly or directly replace the other. Imperfect substitutes are close substitutes but not perfect substitutes. Unlike perfect substitutes, imperfect substitutes satisfies same utility but has different characteristics and therefore not entirely substitutable. For example, while one may want to have the 40 marks too, he'd rather have 60 marks even if the criteria for a 60 mark score was increasingly hard.

Answer: n=4
Step-by-step explanation: 4/4=1 and 16/4=4 (1,4) n=4
Area = πr²
Area = 3.14* 6²
A = 3.14 * 36
A = 113.04
Now find the area of the other one.
<span>Area = πr²
A = 3.14 * 0.75</span>²
A = 1.76625
Now subtract them.
113.04 - 1.76625 = 111.27375
Now, we have our answer: A = <span>111.27375
However, I don't see why they told you to have an exact answer for the area. You can't have an exact answer when you use 3.14 for pi.</span>
