Answer:

7/14 and 20/40 are proportional.

Step-by-step explanation:

We're looking for the pairs of ratios where the two ratios are equal.

6/21 and 2/42 are not equal, although 6/21 and 12/42 would be equal.

25/100 and 50/150 are not equal.

18/24 and 6/12 are not equal.  Notice that dividing 18 and 24 by 6 results in 3/8, which does not equal 6/12 or 3/6 or 1/2.

In the last case, notice that 7/14 = 1/2 and 20/40 = 1/2.  This pair of fractions is proportional.  Note that 20/7 times 7 is 20 (the numerator of the 20/40), and that 20/7 times 14 is 40.  The constant of proportionality is thus 20/7.

Consider that a population of fruit flies grew in a 40-day experiment. Average rate of change: 9 flies/day. Find the average gro
Harman [31]

Answer: Average Growth Rate is 24.19%

Step-by-step explanation:

Given that;

Average rate of change = 9 flies/day

Average growth rate of change = ?

we can determine the average growth rate of change from the expression;

Average Annual Growth Rate = [((Present Value - Past Value)^1/N) - 1 ]  × 100%]

Now our present value; 30th day = 9 × 30 = 270

past value; 05th day = 9 × 05 = 45

the value of N = 30 - 5 = 25

so we substitute

Average Annual Growth Rate = [((270 - 45)^1/25) - 1 ]  × 100%]

=  ([1.2419 - 1) × 100]

= 24.19%

Therefore Average Growth Rate is 24.19%
