Answer:

48.14= $58.25

$97.92= 81.27 euro

Step-by-step explanation:

Giving the following information:

1 Euro is currently valued at 1.21 U.S. Dollars.

<u>First, we need to calculate the dollar value of 48.14 euros.</u>

Proportion equation used for answer below: 1e= 1.21d

48.14*1.21= $58.25

<u>Now, the euro value of 97.72 dollars.</u>

Proportion equation used for answer below: (1:1.21) 0.83

1 dollar equals 0.83 euro.

97.92*0.83= 81.27 euro

, list the first five terms of each sequence, and identify them as arithmetic or geometric.
Serhud [2]

Answer:

The first 5 terms are -6,-25,-44,-63 and -82

The sequence is arithmetic

Step-by-step explanation:

Given that A(n + 1) = A(n) − 19 for n ≥ 1 and A(1) = −6

A(1) = -6

A(2) = A(1) − 19 = -6 - 19 = -25

A(3) = A(2) − 19 = -25 - 19 = -44

A(4) = A(3) − 19 = -44 - 19 = -63

A(5) = A(4) − 19 = -63 - 19 = -82

So the first 5 terms are -6,-25,-44,-63 and -82

If they are in arithmetic the common difference will be same, if geometric common ratio will be same.

Let us check common difference,

                       -25-(-6) = -19

                       -44-(-25) = -19

                       -63-(-44) = -19

                       -82-(-63) = -19

So common difference is same, so the sequence is arithmetic.

There are 6 red socks and 8 black
RideAnS [48]

Answer:

24/91

Step-by-step explanation:

6 red socks and 8 black = 14 socks

P( red) = red/total = 6/14 = 3/7

Keep the red sock

5 red socks and 8 black = 13 socks

P(black) = black / total = 8/13

P(red, black, keeping the sock) = 3/7 * 8/13 = 24/91
