60

Step-by-step explanation:

9 ÷ 15 = 0.6

Move decimal 2 places 0.6 -> 60

The answer to your question is 60

Step-by-step explanation:

Divide

                        0.15   9

Process

1.- Multiply both dividend and divisor by 100, to avoid dividing decimals

       0.15 x 100 = 15

            9 x 100 = 900

2.- Divide normally

                                60

                       15   900

                            -90

                                 00

3.- The result is 60 and the remainder is 0

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
