wel
The first thing we must do for this case is to define a variable.
 We have then:
 x: number of years before the Russo-Japanese conflict began
 We write now the inequality that models the problem.
 We know that the conflict began in the year 1904, therefore, all the previous years are given by:
 x <1904

A square has an area of 121 square centimetres.<br> What is its perimeter?
Karolina [17]

Answer:

  44 cm

Step-by-step explanation:

The area of a square is the square of the side length. This means the side length is the square root of the area.

  s = √A = √(121 cm²) = 11 cm

The perimeter of a square is the sum of its side lengths. There are 4 equal-length sides, so the perimeter is 4 times the length of one side:

  P = 4s = 4(11 cm)

  P = 44 cm

The perimeter of the square is 44 cm.

Convert from scientific notation to standard form 4.83 x 10^-3
ANTONII [103]

4.83 x 10^-3 can be re-written in standard form by moving the decimal point 3 units to the left:   0.00483.

Note:  If you want to be mathematically correct, please write 10^(-3), not 10^-3.  If the exponent is +, you don't need the parentheses.
