k′l′m′n′ is a dilation image of klmn. which is the correct description of the dilation?

a) an enlargement with scale factor 1/2

b) an enlargement with scale factor 2

c) a reduction with scale factor 1/2

d) a reduction with scale factor 2

 The answer is (B) an enlargement with scale factor 2.

Step-by-step explanation:  The quadrilateral K'L'M'N' is the dilation image of the quadrilateral KLMN. We are to select the correct description of the dilation from given four options.

We can record from the given graph that in quadrilateral KLMN, the length of one side is

KN = 1.5 units,

and in quadrilateral K'L'M'N', the length of the corresponding side is

K'N' = 3 units.

Therefore, the scale factor will be

So, there will be an enlargement with a scale factor 2.

Thus, (B) is the correct option.

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
