Drag each tile to the correct location. Each tile can be used more than once, but not all tiles will be used.

AysviL [449]

Answer:

y=770-55x --- given

y - 770 = 770 - 55x - 770 ----subtraction property of equality

y = -55x + 770 ---Simplification

y-770/-55 = -55x/-55 --- Division property of equality

-y-770/55=x---Simplification

Look at the figure and answer

andreyandreev [35.5K]

Answer:

$\cos x=\dfrac{8}{f}$

Step-by-step explanation:

Given that,

$\tan x=\dfrac{e}{8}\\\\\sin x=\dfrac{e}{f}$

We need to find the value of cos x.

We know that,

$\tan\theta=\dfrac{\sin\theta}{\cos\theta}$

Using the above relation,

$\dfrac{e}{8}=\dfrac{\dfrac{e}{f}}{\cos x}\\\\\cos x=\dfrac{\dfrac{e}{f}}{\dfrac{e}{8}}\\\\=\dfrac{e}{f}\times \dfrac{8}{e}\\\\=\dfrac{8}{f}$

So, the value of cos x is equal to $\dfrac{8}{f}$ .

A sound wave travels through iron at a rate of 5120\,\dfrac{\text{m}}{\text{s}}5120 s m 5120, start fraction, start text, m, e

klio [65]

Answer:

18432 km/h

Step-by-step explanation:

It is given that a sound wave travels through iron at a rate of 5120 m/s.

We know that

1 km = 1000 m

1 hour = 60 minutes

1 minutes = 60 second

Using these conversions we get

1 m = 0.001 km

1 hour = 3600 second

$5120\text{ m/s }=5120\times 0.001\times 3600\text{ km/h}$

$5120\text{ m/s }=18432\text{ km/h}$

Therefore, the sound wave travels through iron at a rate of 18432 km/h.
