Answer: 560 tickets

Step-by-step explanation:

3/4 = 420/x; now cross multiply:

3x = 4(420)

3x = 1,680; now divide both sides by 3, and you get x = 560

What is the sound level for a noise that has an intensity of 9.9 × 10-5 watts/m2?
horsena [70]

Given: Sound Intensity ( I ) = 9.9 \times  10^{-5}\frac{watts}{m^2}

We know,  the approximate threshold of human hearing is at 1kHz. In watts/m^2 it's value is =\frac{9.9 \times  10^{-5}}{10^{-12}}⁻¹² W/m².

So, we can say,  Reference sound intensity(I_0) = 10⁻¹² W/m².

We have formula for "sound intensity level LI in dB" when entering sound intensity.

LI = 10×log (I / Io)  in dB

Plugging values of I and Io in formula.

LI = 10 × log (\frac{9.9 \times  10^{-5}}{10^{-12}})

LI = 10 × log (99000000)

= 10 × 7.99564

LI = 79.96 dB.

Therefore,  79.96 dB is the sound level for a noise that has an intensity of 9.9 × 10-5 watts/m2.

The graph below has the same shape. what is the equation of the graph?
Nataly_w [17]

C; A and B are incorrect because the shift is not vertical, it is horizontal. This is because 3 is in parenthesis or a 'grouping' (same thing if it is in an exponent) and is being modified. Since the graph is being translated down 3 units, D is incorrect since it is a translation up 3 units. The answer is C.

The equation -x = y + 7 written in slope-intercept form is
Drupady [299]

I think that it's B, y = -x - 7 because first you'd subtract y to get it on the other side then add x and then you'd need to make the y positive so you would divide x + 7 by -1 and that would make it y = -x - 7.
