Anything that's half of one another.

4/8

8/16

400/1600

Simplify each and every one of those and you'll get 1/2.

In decimal form, it's 0.5.

Answer:

See below

Step-by-step explanation:

Equivalent fractions are fractions that equate to the same value. For example, 1/2 is equivalent to 2/4, 3/6, 4/8, 5/10, and so on.

Answer:

Step-by-step explanation:

1. The triangles are similar because the sides are proportional and they both hava a right angle.

2. It would be the hypotenuse leg theorem since they are right triangles.

3. The right angle justifies the triangles being similar.

Answer:

Step-by-step explanation:

$24\times\dfrac{1}{3}=\dfrac{24}{3}= \dfrac{3\cdot8}{3}=\dfrac{3}{3}\cdot8 = 1\cdot8 = \boxed{8}$

Not sure why such an old question is showing up on my feed...

Anyway, let $x=\tan^{-1}\dfrac43$ and $y=\sin^{-1}\dfrac35$ . Then we want to find the exact value of $\cos(x-y)$ .

Use the angle difference identity:

$\cos(x-y)=\cos x\cos y+\sin x\sin y$

and right away we find $\sin y=\dfrac35$ . By the Pythagorean theorem, we also find $\cos y=\dfrac45$ . (Actually, this could potentially be negative, but let's assume all angles are in the first quadrant for convenience.)

Meanwhile, if $\tan x=\dfrac43$ , then (by Pythagorean theorem) $\sec x=\dfrac53$ , so $\cos x=\dfrac35$ . And from this, $\sin x=\dfrac45$ .

So,

$\cos\left(\tan^{-1}\dfrac43-\sin^{-1}\dfrac35\right)=\dfrac35\cdot\dfrac45+\dfrac45\cdot\dfrac35=\dfrac{24}{25}$
