Ok

fisrt we determine sign
negative divided by positive=negative
answer is negative
disregard any signs for now
first convert to from mixed to improper
3 and 1/5=3+1/5=15/5+1/5=16/5

(16/5)/(2/15)
remember the fancy 'invert and multiply'
I won't tell you why because it would take too long, but if you want to know why we invert and multiply, just ask in comments

so, invert an multilply
(a/b)/(c/d)=(ad)/(bc)
(16/5)/(2/15)=(16*15)/(5*2)=(240)/(10)=24

the answer is negative so

Over the last 2.5 years, the water level in a lake has changed by -0.3 feet per year. Scientists predict that the water level wi
klio [65]

Answer:

Step-by-step explanation:

A)

"In the last 2.5 years, the water level has decreased 0.75 feet."

In the very first statement it has been stated that over the last 2.5 years, the water level in a lake has changed by -0.3 feet per year. That means in the last 2.5 years , total decrease in level is as follows

2.5 x - 0.3 = - .75 ft .

So the statement is true.

B)

"The overall change of the water level after 7.5 years will be -2.75 feet."

This statement appears to be false based on information provided

No prediction regarding rate of decrease for a period beyond 5 year  has been made so any statement with respect to a timeline of 7.5 years may turn out to be false.

C)

"The change in water level each year for the next 5 years will be -0.4 feet. "

This statement prima-facie appears to be true  because rate of decrease stated in the statement is 0.4 ft /year for next 5 years .

D )

"The overall change in water level for the next 5 years is equal to 5(0.4)"

this statement is true

as change in one year = .4

change in 5 years = 5 x .4
