<h3>Answer: Choice A) </h3><h3>The circumference of one of the circles would be greater than the longer side of the rectangle</h3>

=============================================

Why this is the answer:

The rectangle has 3 circles packed inside it each with the same radius r. The diameter of each circle is 2r, so 3 of them result in a total rectangle length of 3*2r = 6r.

While one circle has a circumference of C = 2*pi*r = 2*3.14*r = 6.28r

Comparing 6.28r and 6r, we see that 6.28r is larger than 6r

6.28r > 6r

6.28 > 6 ... dividing both sides by r (the inequality sign doesn't change because r > 0)

This is true for any value of r.

Your father earned $34,000 per year in 1984. To the nearest dollar, what is that equivalent to in 2014 if the CPI in 2014 is 2

xeze [42]

Answer:

The answer is : 70288.46

Step-by-step explanation:

Your father earned $34,000 per year in 1984.

The CPI in 2014 is 215 and the CPI in 1984 is 104.

The CPI or consumer price index examines the weighted average of prices of goods and services like transportation, food etc.

The Current income equivalent will be = value in 1984 X ( CPI in 2014/CPI in 1984)

$34000\times\frac{215}{104}$ = 70288.46
