Hope this helps, should be right

<span>Using
the information give, we can create two equations with two unknows as shown
below:
50U+20E=10680 and
U+E=280.
Where U represents Unlimited ride passes
and E represents Entrance-only passes. We can use the second equation to find
the value of U in relation to E. So that U is represented as U=282-E. We then
proceed to substitute E in the first equation using the value we assigned it
in relation to U so that we can have only one unknown value in the equation.
So 50U+20E=10680 becomes 50(282-E)+20E=10680. Simplifying this equation,
14100-50E+20E=10680. Putting the unknowns on one side we end up with
14100-10680=50E-20E. Solving for E, we end up with E=114. U can also be
calculated by substituting the already known value of E in the simpler
equation U=280-114. This means that the value of U is 168. So the number of
unlimited passes that were sold is 168</span></span>
Heat touching the surface of the ice cube causes it to melt. So a cube with larger surface area will allow more contact with the heat as compared to the cube with small surface area.
If the amount of heat that is being transferred to the ice cube from the surrounding environment is more, it will melt more quickly. If the ice cube melts more quickly it cannot serve its purpose i.e. to cool down the liquid it is dipped into.
Therefore, for better results, the surface area of the ice cube should be less, so that less heat touches its surface and the process of melting is slow.
Answer:
Step-by-step explanation:
it's going to alternate back and froth between positive and negative, maybe it will make one of those "telescoping" sequences
