How do you decide by which power of 10 to multiply an equation when writing a decimal with repeating digits as a fraction?

1 answer:

6 0

For the repeating fraction, It depends on the denominator as which power of 10 is the nearest factor of denominator.

According to the statement

we have to find that the power of 10 which is multiply the equation by which writing a decimal with repeating digits as a fraction.

So, For this purpose, we know that the

Fraction is a number expressed as a quotient, in which a numerator is divided by a denominator. In a simple fraction, both are integers.

So, From the given information:

To decide the power of 10 to multiply an equation with repeating digits ; Round the equation to the required significant numbers.

when the numerator of an equation is divided by the denominator and the result is not a whole number ( i.e. number with some decimals)and sometimes the decimal places are unending. to present the result properly we have to round off the number to the nearest significant number, then you can multiply the equation with the power of 10, in relation to the number of significant places you rounded off.

Example :

5/200 = 0.025

To express this answer with the power of 10

0.025 = 2.5 * 10^-2

Here the power of 10 is -2.

So, For the repeating fraction, It depends on the denominator as which power of 10 is the nearest factor of denominator.

Please help me to solve this

Answer:

Below in bold.

Step-by-step explanation:

First find the height by use Pythagoras theorem on the right triangle:

h = sqrt (5^2 - 4^2)

= sqrt 9

= 3.

Volume of the prism = area of the triangle * length

= 1/2 * 3 * 4 * 10

= 1/2 * 12 * 10

= 60 cm^3.

Total area = area of 2 triangles + area 0f 3 rectangles

= 2 * 1/2 * 3 * 4 + 3 * 10 + 4 * 10 + 5 * 10

= 12 + 30 + 40 + 50

= 132 cm^2.

The correct answer is A.

To create the line linger than AB, a straightedge was used.

To measure AB, a protractor was used.

This is how CD was created.

When referring to the normal probability distribution, there is not just one; there is a "family" of normal probability distribu

pishuonlain [190]

<span>A probability distribution is formed from all possible outcomes of a random process (for a random variable X) and the probability associated with each outcome. Probability distributions may either be discrete (distinct/separate outcomes, such as number of children) or continuous (a continuum of outcomes, such as height). A probability density function is defined such that the likelihood of a value of X between a and b equals the integral (area under the curve) between a and b. This probability is always positive. Further, we know that the area under the curve from negative infinity to positive infinity is one. The normal probability distribution, one of the fundamental continuous distributions of statistics, is actually a family of distributions (an infinite number of distributions with differing means (ÎĽ) and standard deviations (Ď). Because the normal distribution is a continuous distribution, we can not calculate exact probability for an outcome, but instead we calculate a probability for a range of outcomes (for example the probability that a random variable X is greater than 10). The normal distribution is symmetric and centered on the mean (same as the median and mode). While the x-axis ranges from negative infinity to positive infinity, nearly all of the X values fall within +/- three standard deviations of the mean (99.7% of values), while ~68% are within +/-1 standard deviation and ~95% are within +/- two standard deviations. This is often called the three sigma rule or the 68-95-99.7 rule. The normal density function is shown below (this formula wonâ€™t be on the diagnostic!)</span>
