The corresponding sides of two similar triangles are proportional.
The corresponding angles of two similar triangles are congruent

Corresponding sides can be changed, yet they still have to be proportional. If they are congruent, then the triangles will be congruent.
The angles always have to be congruent however, or else the whole shape of the triangle will be changed and the triangle will not be similar.

When the average price of an item increases from p1 to p2 over a period of n years, the annual rate of inflation r (in decimal f

Natali [406]

Answer:

the annual rate of inflation r is 0.023

Step-by-step explanation:

Given by the expression:

$r=(\frac{p_2}{p_1})^{1/n}-1$

The average price of a gallon of milk increased from $0.36 in 1913 to $3.53 in 2013.

Let $p_1 = 0.36$

$p_2 = 3.53$

n = 2013 - 1913 = 100

replacing our values into the given equation; then the annual rate of inflation r is as follows:

$r=(\frac{3.53}{0.36})^{1/100}-1$

r = 0.023

Hence, the annual rate of inflation r is 0.023

elena55 [62]

Answer:

120,960 ways

Step-by-step explanation:

Assuming that each piece is unique, then the order of each piece matters.

There are 9 pieces in total, there are 3 options for the first piece (3 piano pieces), and the remaining 8 pieces can be permuted. The number of possible arrangements is:

$n=3*\frac{8!}{(8-8)!}\\ n=3*8*7*6*5*4*3*2*1\\n=120,960\ ways$

The program can be arranged in 120,960 ways.

It would be written like so:

Though I'm not sure how you share 25 stamps among 4 friends equally without having to rip 1 of the 25 stamps into quarters.
