Answer:

(a/c)/c=(b/c)/c

Step-by-step explanation:

Inverse means the opposite notation so you would switch the multiplication for division and I don't know what you mean by additive notation.

A shade of yellow light with a wavelength of 5.8×10-7 m and a frequency of 5.17 × 10-14 Hz

harina [27]

Step-by-step explanation:

We have,

The wavelength of yellow light, $\lambda=5.8\times 10^{-7}\ m$

Frequency of yellow light, $f=5.17\times 10^{-14}\ Hz$

It is assumed to find the speed of light in the yellow light.

The speed of a wave is given in terms of wavelength and frequency as :

$v=f\lambda\\\\v=5.17\times 10^{-14}\times 5.8\times 10^{-7}\\\\v=2.99\times 10^{-20}\ m/s$

So, the speed of light in a shade of yellow light is $2.99\times 10^{-20}\ m/s$ .

Answer:

Thus, option A is correct.

Explanation:

match the proportions

$240,000 → 60%

x → 100%

set up a equation:

$\sf \dfrac{60}{100} = \dfrac{240,000}{x}$

$\sf x = \$400,000$

What are the values of the variables in the triangle below?

harkovskaia [24]

Answer:

D) x=9 ; y=3√(3)

Step-by-step explanation:

$Sin(30)=\cfrac{y}{6\sqrt{3} }$

$\cfrac{18y}{6\sqrt{3}}=18\sin \left(30^{\circ \:}\right)$

$\sqrt{3}y=9$

$\cfrac{\sqrt{3}y}{\sqrt{3}}=\cfrac{9}{\sqrt{3}}$

$y=3\sqrt{3}$

$Cos(30)=\cfrac{x}{6\sqrt{3} }$

$\cfrac{18x}{6\sqrt{3}}=18\cos \left(30^{\circ \:}\right)$

$\sqrt{3}x=9\sqrt{3}$

$\cfrac{\sqrt{3}x}{\sqrt{3}}=\cfrac{9\sqrt{3}}{\sqrt{3}}$

$x=9$

Therefore, x=9 and y=3√(3)
