Allisa [31]

First you plug in the data to the formula. So it will be 2(1/3+1/2). You then want to add the fractions together but must first find the common denominator which will be 6. So it is 2(2/6+3/6). The fractions then add up to be 5/6. So all you have to do is multiply it by 2 to get 5/3 which simplifies to 1 2/3 so it is D.

Answer:

x = 3.87

Step-by-step explanation:

Using the right angle altitude theorem, we know that all three triangles are congruent, so the lengths of corresponding sides of the triangles are in proportion..

AD/DB = DB/DC

15/x = x/1

x² = 15

x = √15

x = 3.87

liraira [26]

Answer:

150.51 dB

Step-by-step explanation:

Data provided in the question:

decibel level of sound at 161 km distance = 180 dB

d₁ = 161 km

d₂ = 4800 km

I₁ = 180 db

The formula for intensity of sound is given as:

I = $10\log(\frac{I_2}{I_1})$

and the relation between intensity and distance is given as:

I ∝ $\frac{1}{d^2}$

or

Id² = constant

thus,

I₁d₁² = I₂d₂²

or

$\frac{I_2}{I_1}=\frac{d_1}{d_2}$

therefore,

I = $10\log(\frac{d_1}{d_2})^2$

or

I = $10\times2\times\log(\frac{161}{4,800})$

or

I = 20 × (-1.474)

or

I = -29.49

Therefore,

the decibel level on Rodriguez Island, 4,800 km away

= 180 - 29.49

= 150.51 dB

Shuan rides his bike at a speed of 19 mph how far in miles is shuan travel in 25 minutes

irga5000 [103]

Answer:

7.92 miles (aprox.)

Step-by-step explanation:

1 hour = 60 minutes

19mph = 19miles/hour = 19miles/60 minutes

Proportions:

19 miles ⇔ 60 minutes

W miles ⇔ 25 minutes

W = 19*25/60

W = 7.92 miles (aprox)
