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

Soloha48 [4]

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.

Option c: $y=-\frac{1}{2} x-2$ is the equation of the line

Explanation:

The equation of line EF is given by $y=-\frac{1}{2}x+6$

To determine the equation of line in slope intercept form is given by $y=m x+c$ where m is the slope.

From the above equation, the slope of the equation is $m=-\frac{1}{2}$

Let us substitute the slope in the formula $y=m x+c$

Thus, the new equation is

$y=-\frac{1}{2} x+c$

Also, it contains the point (0,-2)

Substituting the point in the equation $y=-\frac{1}{2} x+c$ , we get,

$\begin{aligned}&-2=-\frac{1}{2}(0)+c\\&-2=0+c\\&-2=c\end{aligned}$

Thus, substituting the value of c in the equation $y=-\frac{1}{2} x+c$ , we have,

$y=-\frac{1}{2} x-2$

Thus, the equation of line parallel to the line EF in slope intercept form is $y=-\frac{1}{2} x-2$

Hence, Option c is the correct answer.

Juan brought 4 Tshirts and leather jacket. The T shirts were all the same price, and the price of the leather jacket was 6 times

Alex

Let us say that:

x = the number of T shirts bought = 4

y = the number of leather jackets bought = 1

a = the price of the T shirts

b = the price of the leather jackets

With the given variables, we can say that the total cost is:

total cost = a x + b y

Since, b = 6 a, therefore:

total cost = a x + 6 a y

total cost = a (x + 6 y)

Since total cost is 209, therefore we can calculate for a since x and y are also given:

209 = a (4 + 6 * 1)

209 = a (10)

a = $20.9

<span>Therefore each T shirt cost $20.9</span>

the sum of the ages of two brothers is 46. The younger brother is 10 more than a third of the older brother's age. How old is th

castortr0y [4]

Let's try to do this with a little guess and check.
We'll use numbers easily divided by 3 for the older brother's age.
If the older brother is 30, the younger brother is 16. (30 + 16 = 46)
Now, we check that with the 10 + 1/3 the older brother's age.
30 ÷ 3 = 10
10 + 10 = 20
20 > 16
That one doesn't work.
Let's try 24 for the older brother's age.
That means the younger brother would be 22, because 24 + 22 = 46.
24 ÷ 3 = 8
8 + 10 = 18
18 < 22
That one doesn't work, either.
We'll try one more. If the older brother is 27, the younger brother would be 19. (27 + 19 = 46)
27 ÷ 3 = 9
9 + 10 = 19
19 = 19
This one fits all the requirements of the problem.
That means that the answer to the question of "how old is the younger brother?" is
The younger brother is 19 years old.
