To encode a message, James first replaces each letter within the message with its
corresponding number, where A = 1, B = 2, · · · , Y = 25, and Z = 26. Next, James
multiplies each number by 3 and then subtracts 5, and continues this process a total
of n times. For example, when n = 2 the letter D is encoded to the number 16.
If James encoded a four letter message to the four numbers 367 205 853 1339, what
is the value of n that he used?
(A) 2 (B) 3 (C) 4 (D) 5 (E) 6

Answers

A is the correct answer

The value of n is 4. That means, the process is applied 4 times.

What is multiplication?

Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

Given:

To encode a message,

James first replaces each letter within the message with its corresponding number, where A = 1, B = 2, · · ·, Y = 25, and Z = 26. Next, James multiplies each number by 3 and then subtracts 5, and continues this process a total of n times.

To find the value of n:

We use process inversely.

Let m be the given number.

For example,

m = 16

The inverse process;

add 5 and then divide by 3 until we get the whole number.

So, first time

(16 + 5)/3 = 21/3 = 7,

Second time applying process,

(7+5)/3 = 4.

And the corresponding letter is D.

And the value of n is 2.

Now, m = 367

Applying process inversely,

First time,

(367 + 5) / 3 = 124

Second time,

(124+5)/3 = 43

Third time,

(43+5)/3 = 16

Fourth time,

(16+5)/3 = 7

m = 205

Applying process inversely,

First time,

(205+ 5) / 3 = 70

Second time,

(70+5)/3 = 25

Third time,

(25+5)/3 = 10

Fourth time,

(10+5)/3 = 5

m = 853

Applying process inversely,

First time,

(853+ 5) / 3 = 286

Second time,

(286+5)/3 = 97

Third time,

(97+5)/3 = 34

Fourth time,

(34+5)/3 = 13

m = 1339

Applying process inversely,

First time,

(1339+ 5) / 3 = 448

Second time,

(448+5)/3 = 151

Third time,

(151+5)/3 = 52

Fourth time,

(52+5)/3 = 19

We applied the process 4 times.

Therefore, the value of n is 4.

Get a common denominator

3 1/8 - 1/2 *4/4

3 1/8 - 4/8

Borrow 1 from the 3 in the form of 8/8

2 + 8/8+1/8 - 4/8

2 9/8 - 4/4

2 5/8

Answer:

21/8 or 2 5/8

Step-by-step explanation:

Step 1: Find a common denominator for 1/2 to have the same denominator as 3 1/8:

1/2 is equal to 4/8, which has the same denominator as 3 1/8.

Step 2: Convert the mixed fraction into an improper fraction so it will be easier to subtract.

3 1/8 = 25/8

Step 3: Now subtract:

25/8 - 4/8 = 21/8 or 2 5/8 (keep the denominator the same)

A. b=2 to the h power

B. b=2 to the h power plus 1

C. b=2h

D. b=2h+1
sorry, it shows it a bit messed up. the number of hours is shown on the left side with the numbers directly below it. the number of bacteria is the second column.

Answers

Answer:

A. b = 2 to the h power

Step-by-step explanation:

For the table:

When:

h = 0, b = 1, so 1 = 2^0, 1 = 1

h = 1, b = 2, so 2 = 2^1, 2 = 2

h = 2, b = 4, so 4 = 2^2, 4 = 4

h = 3, b = 8, so 8 = 2^3, 8 = 8

h = 4, b = 16, so 16 = 2^4, 16 = 16

I got A. B=2 to the h power

192.78 inches
246.78 inches
277.56 inches
331.56 inches

please help lol

Answers

Answer:

The answer is 192.78 inches

Step-by-step explanation:

An oval is formed by a rectangle with semicircles at each end. We can visualize this easily.

The length of the rectangle is 54 inches.

The width of the rectangle is 27 inches.

The perimeter of rectangle is =

= 162 inches

And because there are two semicircles, we can combine them to form a circle. So, perimeter of a circle is called a circumference.

The width of the rectangle forms the diameter, so its half will be the radius.

r =

The circumference is given by :

= inches

Now as the described oval shape is a complete figure without lines inside, we will subtract the width of both sides of the rectangle from the complete perimeter.

The complete perimeter is = inches

The inner edge perimeter will be = = 192.78 inches
