Answer:

a) $4000

b) $2000

Step-by-step explanation:

interest = Principal x rate as decimal x time

interest = 20,000 x 0.05 x 4

interest = 4000

interest = Principal x rate as decimal x time

interest = 20,000 x 0.05 x 2

interest = 2000

you save $2000 if you pay after 2 years

Calculate the measure of arc AC if the measure of arc CD is 170 degrees and arc AB is 80 and AB||CD.

CaHeK987 [17]

Answer:

AC = 55°

Step-by-step explanation:

In this geometry, arcs AC and BD have the same measure. The sum of the parts of arc CD will total the measure of CD.

AC + AB + BD = CD

2AC +80 = 170

AC = 110/2 = 55

The measure of arc AC is 55°.

Answer: $scale\ factor=2.5$

Step-by-step explanation:

First, it is important to know that the scale factor is defined as a ratio of two corresponding side lengths of similar figures.

Similar figures are defined as those figures in which the ratio of their corresponfing side lengths are equal and their corresponding angles are congruent (which means that they have the same measure).

In this case, you know that the rectangles given in the picture are similar.

Therefore, you can find the scale factor that was applied to the first rectangle to get the resulting image, dividing the lenghts of their corresponding sides.

Then, this is:

$scale\ factor=\frac{7.5}{3}\\\\scale\ factor=2.5$
