Answer: Hence, the length of sides will be 3.2 in, 4.8 in., 6.4 in.

Explanation:

Since we have given that

Ratio of lengths of the sides of ΔABC is 2:3:4

So, the length of first side 'AB' be 2x

Length of second side 'BC' be 3x

Length of third side 'AC' be 4x

Now, we have given that M,N,K are the midpoints of the sides ,

As shown in the figure below:

As we know the Mid-point theorem which states that the line joining the midpoints is always parallel to the third side and half to the third side too.

So by applying this we get,

Length of MN is given by

Length of NK is given by

Length of MK is given by

Also, we have given that perimeter of ΔMNK is 7.2 in.

So,

So, the length of AB is given by

Length of AC is given by

Length of BC is given by

Hence, the length of sides will be 3.2 in, 4.8 in., 6.4 in.

kozerog [31]

Answer:

The rock cycle describes how rocks change as a result of natural processes. The rock cycle forms new rocks using the crystallization, erosion and compaction processes. This makes the correct answer: D: all of the above. Igneous rocks for example are rocks formed from the crystallization( formation of rock crystals in cooling magma) of a liquid. Sedimentary rocks are formed by erosion. However, in order to form a sedimentary rock, the accumulated sediment must become compacted and cemented together.

Describe the relationship between the two quantities. amount of money earned; number of hours worked a. inverse c. joint b. dire

tatyana61 [14]

The relationship between the two quantities that is the amount of money earned and number of hours worked is direct .

The correct option is B

When two values x and y can be represented in the general form y = kx, where k is the proportionality constant, then there is a proportional relationship between them.

In the equation y= kx, the amount of money a person makes is directly related to the amount of time they work.

FOR EXAMPLE -

Since a person earns $100 for 5 hours of work, we can use this information to find the value of k. Substituting 100 and 5 into the equation results in 100 = k 5. Solving for k produces k = 20. Now we can write a specific equation relating the money earned and the hours worked as y = 20x.

y= 20(18) = $360
