Answer:

ROI = 66.67%

Step-by-step explanation:

Given:

josh investment= $12,000

Received sum= $20,000

ROI=?

ROI is the return on investment that gives the loss or gain in any investment and is calculated by the following formula:

ROI= (interest/investment) x 100

Finding interest:

interests= received sum- investment

= 20,000-12,000

=8000

Putting values in ROI formula we get:

ROI= (8000/12000) x 100

= 66.67%

Hence the return on investment is 66.67%!

Find a substance half-life in days. round your answer to the nearest tenths

jeka57 [31]

A 33 gram sample has k value of .1124
(Actually I think the problem SHOULD be worded: A 33 gram sample has k value of -.1124/days)

See attached graphic:
Half-Life = ln (.5) / k
Half-Life = -.693147 / -.1124/days
Half-Life = 6.1667882562 days
