It would be positive one. Go up one over four then down one over four.
Answer:
a third 1/3
Step-by-step explanation
first write the equation
express 8 to power form = 2^3x don't forget the unknown , which is x
it becomes ; 2^3x = 2^1
since the base numbers are same, cancel them.
equate the powers ; 3x=1
divide both sides by the number next to the unknown to get the answer.

Step-by-step explanation:
Given two variables (say x and y); the constant of proportionality is the ratio between these to variables.
Illustration; y is directly proportional to x
The above statement can be represented as:
When converted to an equation, you get
k, in the above equation, represents the constant of proportionality
Divide both sides by x to solve for k
Take for instance:
Divide both sides by x
--- 3 is the constant of proportionality

Answer:
the speed of the plane when there is no wind is 212.25 mi/hr
Step-by-step explanation:
Let v represent the speed of the plane without wind.
Wind speed = 20.1 mi/hr
The resultant speed with wind is;
v + 20.1 mi/hr
The resultant speed against wind is;
v - 20.1 mi/hr
Let t represent the time for the travel.
With wind;
(v+20.1)t = 630 ......1
Against wind;
(v-20.1)t = 521 ......2
Divide equation 1 by 2
(v+20.1)/(v-20.1) = 630/521
Cross multiply;
521(v+20.1) = 630(v-20.1)
Collecting like terms;
v(630-521) = 20.1(630+521)
v = 20.1(1151)/109
v = 212.25 mi/hr
the speed of the plane when there is no wind is 212.25 mi/hr
