The wind speed s (in miles per hour) is related to the distance (in miles) the tornado travels by the equation s = 93log d + 65.

Vesnalui [34]

Answer:

The distance the tornado traveled was approximately 205 miles.

Step-by-step explanation:

The equation representing the relationship between the wind speed (in miles per hour) and the distance the tornado travels (in miles) is:

$s=93\log d+65$

Compute the value of <em>d</em> for <em>s</em> = 280 as follows:

$s=93\log d+65$

$280=93\log d+65$

$93\log d=280-65\\93\log d=215$

$\log d=2.312\\$

$d=10^{2.312}\\d=205.035\\d\approx 205$

Thus, the distance the tornado traveled was approximately 205 miles.

-12x - 0.4 > 0.2(36.5x + 80) - 55 Remove the brackets.

-12x - 0.4 > 7.3x + 16 - 55 Combine the like terms on the right

-12x - 0.4 > 7.3x - 39 Add 12x to both sides

- 0.4 > 7.3x + 12x - 39

- 0.4 > 19.3x - 39 Add 39 to both sides.

-0.4 + 39 > 19.3x Combine like terms on the left

38.6 > 19.3x Divide by 19.3

38.6 / 19.3 > x

2 > x
