Which words describe an air mass likely to be over the northern parts of the pacific ocean?

a.
wet and cold

b.
warm and dry

c.
wet and warm

d.
cold and dry

A. Wet and color because the water is cold, and the air also might be a little wet(?), or gumid (a better way to say it) since it's over water, and evaporation and stuff. Hopes this helps! Sorry if I'm incorrect.

(A) is correct. Maritime polar air masses form over the Northern Pacific ocean. They deliver moist , cool air.

John had 72 pins originally.

Step-by-step explanation:

Let x represent the total number of pins that John had originally.

John divided his souvenir hat pins into two piles. The two piles had an equal number of pins. This means that each pile has x/2 pins.

He gave his brother one-half of one-third of one pile. This means that the number of pins that he gave his brother is

1/2 × 1/3 × x/2 = x/12 pins

The total amount left is

x/2 + (x/2 - x/12) = x/2 + 5x/12 = 11x/12

John had 66 pins left. Therefore

11x/12 = 66

11x = 66 × 12 = 792

x = 792/11 = 72
