Answer: The ice sheet's thickness decrease every 6 weeks= 1.5 meters

Step-by-step explanation:

GIven: At the beginning of spring, the ice starts to melt. The variable sss models the ice sheet's thickness (in meters) t weeks after the beginning of spring. s=-0.25t+4

At t=0, s=4

So, Thickness of ice sheet at the beginning = 4 meters

Now at t= 6, we get

s=-0.25(6)+4=-1.5+4=2.5

Thickness of ice sheet after 6 weeks = 2.5 meters

Decrease in thickness = 4 meters - 2.5 meters = 1.5 meters

Hence, the ice sheet's thickness decrease every 6 weeks= 1.5 meters

What is the difference?
Ganezh [65]

Answer:

\frac{x^2+4x-1}{x(x+2)}

Step-by-step explanation:

Given

\frac{x+5}{x+2} - \frac{x+1}{x^2+2x} ← factor denominator

= \frac{x+5}{x+2} - \frac{x+1}{x(x+2)}

We require the fractions to have a common denominator.

Multiply numerator/denominator of first fraction by x

= \frac{x(x+5)}{x(x+2)} - \frac{x+1}{x(x+2)}

Subtract terms on numerator leaving the common denominator

= \frac{x^2+5x-x-1}{x(x+2)}

= \frac{x^2+4x-1}{x(x+2)}

What is the value of m in the equation 5m − 7 = 6m 11? 18 1 −18 −1.
riadik2000 [5.3K]

Answer: 18

Step-by-step explanation: 5m - 7 = 6m + 11

Solve for M

5m - 6m = 11+ 7

-m = 18

Divide both sides by -1

-m/-1 = 18/-1

m = -18
