Digiron [165]

Answer:

  1. $60
  2. 103 sales

Explanation:

1. The sweater was originally priced at $80 and then got marked down by 25%. The new price is;

= 80 * ( 1 - 25%)

= 80 * 0.75

= $60

2. Terry earns a basic salary of $250 plus $5 per sale. To make a total of $765, from sales commission alone Terry must make;

= 765 - 250

= $515

Sales to make = 515/5

= 103 sales

Alisiya [41]

Answer:

Explanation:

Ans 1) The approximate elevation of wonderland lake is about 5500 feet, because it lies in the vicinity of the ridge where peak are having contour values upto 6600 feet and the wonderland lake lies on the lower contour of near about 5500 feet.

Ans 2) The peak elevation of poorman hill is 6485 feet as it can easily seen in the map that the highest contour value us 6485 feet. Poorman hill is lying in this contour value.

Ans 3) It is clearly seen and observed from the map that the elevation of the poorman hill is about 6485 feet where as the elevation of the boulder creek present at the south of poorman hill is less than 6000 feet. Thus poorman hill has higher elevation as compared to bank of boulder creek.

Oksanka [162]

Answer:

In the exceptionally cold winter of 1997, Lake Superior froze over between the Wisconsin mainland and Isle Royale. A pack of 8 wolves crossed the ice and reached Isle Royale, an island where they encountered a population of about a dozen wolves. It is estimated that the wolf population on Isle Royale has been isolated for over 100 years (~10 generations). The pack of 8 wolves that crossed the ice would be referred to as <u>founder population</u> and if the wolves interbreed with the island population, <u>genetic drift</u> will occur.

Explanation:

The founder effect occurs when a portion of a population (i-e the founders) separates from the old population to start a new population with different allele frequencies. Hence the pack of 8 wolves that crossed the ice would be referred to as <u>founder population</u> in the given scenario.

Genetic drift is defined as change in the allele frequencies in a population due to chance event. As in the given scenario, the pack of 8 wolves that crossed the ice, interbreed with the island population, thus change in the allelle frequency is occuring in the population , hence <u>genetic drift</u> will occur.
