Would each situation be represented by a positive or a negative number? column a column b 1. 1.5 acres of rainforest are destroyed every second for s seconds. express the change in acreage of rainforest. 2. a tub of water is heated by 0.3 degrees per minute for m minutes. express the change in temperature. 3. a submarine descends at a rate of 0.9 m/s for 90 s. express the change in altitude relative to sea level. 4. a credit card account has 2 charges of $15 and no payments. express the balance of the credit card. a. positive b. negative

1. being destroyed would be a negative number

2. water increasing in temperature is a positive number

3.descending would be a negative number

4. credit card charge would be a positive number

a: inscribed angles

step-by-step explanation:

i reviewed this question with a peer and teacher, seems to be correct, me later

the degrees would remain the same ( the number to the left of the decimal point.

the multiply the decimal by 60 to get the minutes and use the numbers to the left of the decimal point.

then multiply the decimal portion of that by 60 for the seconds and round off as needed.

39 .956652

the 39 remains the degrees.

the minutes = 0.956652 x 60 = 57.39912

the minutes = 57

the seconds = 0.39912 x 60 = 23.95 = 24 ( rounded to nearest tenth)

so 39.956652 = 39 degrees, 57 minutes and 24 seconds

-75.159809

the -75 remains the degrees

the minutes = 0.159809 x 60 = 9.58854

the minutes = 9

the seconds = 0.58854 x 60 = 35.31, rounded to nearest tenth = 35.3 seconds

so -75.159809 = -75 degrees, 9 minutes and 35.3 seconds.

the first coordinate is north or south, since it it positive it is north.

the second number is east or west, because it is negative it is west.

39 degrees, 57 minutes and 24 seconds n

-75 degrees, 9 minutes and 35.3 seconds w
