What are two fractions equivalent to 5/12

saul85 [17]

Answer:

10/24 and 15/36, more answers possible

Step-by-step explanation:

if you multiply both the numerator and denominator by the same number, it will always be equivalent to 5/12, as you can simplify it back to that fraction.

5/12, multiply both by two, and you have 10/24

5/12, multiply both by three, and you have 15/36

Let a=<-4,-3,5> Find a unit vector in the same direction as having positive first coordinate.

Rashid [163]

Answer:

The value is $u = < \frac{2\sqrt{2}}{10} , \frac{3\sqrt{2}}{10} , - \frac{\sqrt{2}}{2}>$

Step-by-step explanation:

From the question we are told that

The vector is a=<-4,-3,5>

Generally the unit vector is $u = ay$

Here y represent the y-coordinate

$u =y$

=> $u =$

Generally the resultant of a unit vector is 1

$|u| = \sqrt{ (-4y)^2 + (-3y)^2 + (5y)^2} = 1$

Hence

$|u| = \sqrt{ 16y^2 + 9y^2 + 25y^2} = 1$

Taking the square of both sides

$16y^2 + 9y^2 + 25y^2 = 1$

=> $50y^2 = 1$

=> $y = \pm \frac{1}{\sqrt{50}}$

=> $y = \pm \frac{1}{5 \sqrt{2}}$

Rationalizing

=> $y = \pm \frac{\sqrt{2}}{10}$

Given that the first coordinate is positive

$y = - \frac{\sqrt{2}}{10}$

Hence the unit vector is

$u =$

=> $u = < \frac{2\sqrt{2}}{10} , \frac{3\sqrt{2}}{10} , - \frac{\sqrt{2}}{2}>$

What percent of 80 is 10

True [87]

I believe that the answer is 12.5%

Reason 100% of 80= 80,

So if 80=100%,

then that means 10=x%

Fore it means that, $x=(\frac{10}{80} )*100$ %=12.5%
