If the expression -120 + 13m represents a submarine that began at a depth of 120 feet below the sea level an ascended at a rate of 13 feet per minute. What was the depth of the submarine after 6 minutes

42 ft

Step-by-step explanation:

(Negative sign symbolises that the submarine is below the sea level or depth of the submarine.)

Hence, the depth of the submarine after 6 minutes was 42 ft.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

351.23
