What part of an hour passes between 11:24 am and 415 am
Bas_tet [7]

Using proportions, it is found that 1685% of an hour passes between 11:24 am and 415 am.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

One hour is composed by 60 minutes. Between 11:24 am and 4:15 am, there are 16 hours and 51 minutes, hence the number of minutes is given by:

M = 16 x 60 + 51 = 1011 minutes.

As a percentage of one hour = 60 minutes, we have that this measure is:

1011/60 x 100% = 1685%.

Hence 1685% of an hour passes between 11:24 am and 415 am.

The lengths of two sides of a triangle are 11 cm and 8 cm. Which is a possible value for the third side of the triangle? A) 1 cm
crimeas [40]

Answer:

All of these are correct.

Step-by-step explanation:

Any length will work for the third side, as long as it is not negative or zero, because a negative length in this case is impossible and if the length is zero then it is not a triangle but merely a line. The length does, however, affect the angles of the corners of the traingle.
