56. In a football game, one team makes seven plays in the first quarter. 56. In a football game, one team makes seven plays in the first quarter The results of those plays are (in order): gain of 7 yards, gain of 2 yards, loss of 5 yards, loss of 12 yards, gain of 16 yards, gain of 8 yards, loss of 8 yards. a. What is the overall gain (or loss) from all seven plays? b. What is the average gain (or loss) per play?

Solution

85. High Temp. = 20 C

low temp. = -15 C

Temp. Difference = 20 - (-15) = 35 C

Half of Temp. difference =35/2 = 17.5 C

Temp. at the half point will be = -15 + 17.5 = 20 - 17.5 = 2.5.C

86.

Low temp. = -8 C

Temp. at the half point = 5 C

Temp. diffrence between low and half = Temp. difference between High and half

5 - (-8) = Th - 5

13 = Th - 5

Th = 13 + 5 = 18 C

87.

Th = -10 C

TL = -15 C

Th - TL = -10 - (-15) = 5 C

Half of temp. difference = 5/2 = 2.5 C

Temp. at Halfway = -10 - 2.5 = -15 + 2.5 = -12.5 C
