Step-by-step explanation:
Stefan sells Jin a bicycle for $150 and a helmet for $18. The total cost for Jin is 140% of what
Stefan spent originally to buy the bike and helmet. How much did Stefan spend originally? How

=18
Answer:
<u>The rate of decreasing of the length is 0.25 cm/s.</u>
Step-by-step explanation:
The surface area of the ice cube is:
Where x is the side of the cube.
Let's take the derivative of A with respect to "t" to get the rate of change.
We know that dA/dt = 6 cm²/s and x is 2 cm, so we just need to solve it for dx/dt which is the rate change of the length.
Therefore, <u>the rate of decreasing of the length is 0.25 cm/s.</u>
