Answer:

FRACTION                               DECIMAL

1/5( 1*2/5*2=2/10)                         0.2

3/10                                               0.3

1/2(1*5/2*5=5/10)                          0.5

7/10                                              0.7

3/4(3*25/4*25=75/100)               0.75

<u><em>NOTE</em></u>:   To conert a fraction into decimal, it is required that the denominator be changed into 10, 100, 1000 and so on.....   By changing the denominator, we have to first select the appropriate number by which you will be able to convert it into 10, 100 or 1000, and you are also required to multiply that number with the denominator as well as numerator. In the first question, 1/5 we can convert the denoinator into 10, 100 or 1000 as the denominator is 5, whatever you choose, the answer will be correct, so, 1*2/5*2 gives 2/10. Since 10 has one zero, the decimal point moves one time towards the left, which gives 0.2. And you can do the rest according to this way, considering the number of zeroes.

The amount of carbon-14 in an object is given by y = ae– 0.00012t where a is the initial amount of carbon and t is the age in ye
Reptile [31]

Answer:

The approximate age of the bone is approximately 11552 years.

Step-by-step explanation:

The current proportion of carbon-14 with respect to its original amount is defined by following formula:

\frac{y}{a} = e^{-0.00012\cdot t} (1)

Where:

y - Current amount of carbon-14, no unit.

a - Initial amount of carbon-14, no unit.

t - Time, in years.

If we know that \frac{y}{a} = 0.25, then the approximate age of the bone is:

t = -8333.333\cdot \ln \frac{y}{a}

t\approx 11552.453\,yr

The approximate age of the bone is approximately 11552 years.

How can you determine if you divided the numbers correctly
Fittoniya [83]
Multiply them back into each other... You would multiply your answer with the number you  divided by (the number ouside the table if you used the table... ) and you should get the larger number you divided.

Mkey [24]

Answer:

  x = 42

Step-by-step explanation:

The marked angles are supplementary, so their sum is 180°.

  (2x +8) +(2x +4) = 180

  4x +12 = 180 . . . . . . . . . simplify

  x +3 = 45 . . . . . . . divide by 4 (because we can)

  x = 42 . . . . . . subtract 3

<em>Additional comment</em>

A "two-step" linear equation like this one is usually solved by subtracting the unwanted constant, then dividing by the coefficient of the variable. Here, we have done those steps in reverse order. This makes the numbers smaller and  eliminates the coefficient of the variable. Sometimes I find it easier to solve the equation this way.

5. The rectangular pool has an area of 520 square feet. The length of 3
erastovalidia [21]

Answer:

z*(z - 3) = 520

Step-by-step explanation:

Use the following representations:

Width:  W  

Length:  L = W + 3, or W = L - 3

Area = L*W = L*(L - 3) = 520

Equation b) is the correct one:  z*(z - 3) = 520
