Express the recurring decimal 0.042 as a fraction in its simplest form.
rodikova [14]

Answer:

7/165

Step-by-step explanation:

This is a mixed recurring decimal (the zero is not repeating)

We take number after the decimal point     042

then we subtract  the non repeating.In this case is 0 so we not subtract anything

This will be the numerator  42

Now ,the denominator:

For each repeating decimal we write a 9 (in this case 2 nines)

For each non repeating decimal we write a zero

Denominator is 990

42/990  =  7/165

7:165 = 0.0424242......

What is the distance between the points (2,10) and (-6, 4) on the coordinate
stellarik [79]

Answer:

The distance between the given points (2,10) and (-6, 4) on the coordinate  plane is 10units

Therefore distance s=10 units

Step-by-step explanation:

Given points are (2,10) and (-6, 4) on the coordinate plane

To distance between the given points :

The distance formula is s=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} units

Let (x_1,y_1) ,(x_2,y_2) be the given points (2,10) and (-6, 4) respectively

Now substituting the values in the distance formula  we get

s=\sqrt{(-6-2)^2+(4-10)^2}

=\sqrt{(-8)^2+(-6)^2}

=\sqrt{8^2+6^2}

=\sqrt{64+36}

=\sqrt{100}

=10

Therefore s=10 units

The distance between the given points (2,10) and (-6, 4) on the coordinate plane is 10units
