A team of storm enthusiasts collected data to show the relationship between the time between seeing lightning and then hearing t

never [62]

Answer:

Proportionality constant = $\frac{1}{5}$

Step-by-step explanation:

From the graph attached,

Data set representing the relation between seeing lightning and the hearing thunder is,

{(15, 3), (25, 5), (35, 7), (45, 9)}

Since, Distance from lightening (d) ∝ Time between lightening and thunder (t)

d = kt

Here k = proportionality constant

k = $\frac{d}{t}$

From the data set one point is (15, 3).

k = $\frac{3}{15}$

k = $\frac{1}{5}$ miles per second

Therefore, proportionality constant is $\frac{1}{5}$ miles per second.

12.6% of<br>RI 149 390bn

galina1969 [7]

Answer: RI 18,823.14

Step-by-step explanation:

I guess that we want to find the 12.6% of Rl 149,390

First, we assume that Rl 149,390 is the 100%

Then we can write an equation like:

Rl 149,390 = 100%

Then if the amount X is the 12.6%, we also have the equation:

X = 12.6%

Then we have the two equations:

X = 12.6%

Rl 149,390 = 100%

If we take the quotient between these two equations we get:

(X/Rl 149,390) = (12.6%/100%)

Solving this for X we get:

X = (12.6%/100%)*(Rl 149,390) = RI 18,823.14
