When a temperature change causes a substance to turn from liquid to sold, we call the process as FREEZING.

For example, if we take a glass of water and keep it in the freezer, water becomes ice in few minutes.

Since the temperature decreases, water freezes and it becomes ice.

In Ice cream shops, they preserve ice creams in freezer box to prevent them from melting.

Answer:

yes

Step-by-step explanation:

By the "rule of 72", the amount will be doubled in 72/I years, where I is the annual interest rate in percent. That is, it can be estimated to take 72/4 = 18 years to double the $240 investment to $480. It would take another 18 years to double it again to $960. So, to achieve a balance of $1500 will be expected to take more than 36 years. The only reasonable answer choice is the one you have selected.

The exact solution is ...

log (1500/240)/log(1 +0.04) ≈ 46.72 years ≈ 47 years.

Which methods could you use to calculate the y-coordinate of the midpointof a vertical line segment with endpoints at (0,0) and

vodka [1.7K]

Answer:

y-coordinate of midpoint of line segment joining the endpoints (0,0) and (0,15) is 7.5

Step-by-step explanation:

Given two end points of line segment that are (0,0) and (0,15). If we have to find the y-coordinate of midpoint of a vertical line segment then we apply mid point formula.

The Midpoint formula is used when one is need to find the exact center point between two given points.

The mid point M of line segment $A(x_{1},y_{1})$ and $B(x_{2},y_{2})$ can be calculated as
