The equation for the speed/distance of a tornado is s = 93 log(d) + 65.
If the speed is 310 mph, what is the distance?

430.93 miles (rounding to the nearest hundredth)

Step-by-step explanation:

s = 93 log(d) + 65

310 = 93 log(d) + 65

245 = 93 log(d)

2.634408602 = log(d)

10^2.634408602 = 10^log(d)

430.9318583 = d

Therefore, if the speed of the tornado is 310 mph, then its distance is about 430.93 miles.

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

47 - 90 = 43

43 - 180 = x

x = 137
