The atmospheric pressure P on a balloon or in aircraft decreases with increasing height . This pressure measured in Millimeters of mercury , is related to the height H (in kilometers) above sea level by the formula p=760e ^ -0.145h. See photo for formula and answer following questions. A.) find the height of an aircraft if the atmospheric pressure is 295 millimeters of Mercury. B.) find the height of a mountain if the atmospheric pressure is 695 millimeters of mercury.

Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18

Solve each equation using the quadratic formula. find the exact solutions. 6n^2 + 4n - 11

Martha has a deck of cards. she has lost some of the cards, and now the deck only contains nine spades, eleven diamonds, eight clubs, and twelve hearts. martha predicts that whenever she draws a card from the deck without looking, she will draw a club one-fifth of the time. which activity would best allow martha to test her prediction? a. randomly draw a card from the box and see if it is a club. b. randomly draw a card. then, continue to draw another card until all eight clubs are drawn. c. randomly draw and replace a card 120 times. then, observe how close to 30 times a club is drawn. d. randomly draw and replace a card 100 times. then, observe how close to 20 times a club is drawn.
