A small construction company has $110,000 set aside in a capital improvement fund to purchase new equipment. If $18,000 is invested at 26%, $22,000 at 15%, and the remaining $70,000 at 22% per year, what is the overall rate of return on the entire $110,000

21.26%

Explanation:

Overall rate of return = Total amount of dollar returns / Total investment

Overall rate of return =  [($18,000 * 26%) + ($22,000 * 15%) + ($70,000 * 22%)] / $110,000

Overall rate of return = ($4680 + $3300 + $15400) / $110,000

Overall rate of return = $23,380 / $110,000

Overall rate of return = 0.21255

Overall rate of return = 21.26%

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'

answer; management is about coping complexity and leadership is about coping with change; i believe this is correct; ///good luck                                          

(b) management: leadership
