Answer: 1.5 meters.
Step-by-step explanation:
Given: At the beginning of spring, the ice starts to melt.
The variable s models the ice sheets thickness in meters t weeks after the beginning of spring.

At t=0, s=4 meters
At t=1, s=3.75 meters
∴It is a linear equation, where the rate of change in thickness = 3.75-4=0.25 meter per minute .
The decrease in ice sheet in every 6 weeks =

Answer:
265 yd squared
Step-by-step explanation:
We can solve this problem by taking the little triangle on the left side and moving it to the right to get a rectangle, and from there we can find the area like its a rectangle
21.2*12.5=265
Answer:
-25 and 2
Step-by-step explanation:
x + y = -23
xy = 50, so y = 50 /x
.
x + 50/x =-23, x^2 +23x - 50 = (x-2)(x+25)
so 2 and -25
