Dependent variable is dependent on the independent variable
m, because the amount of tread lost depends on how many miles you traveled
it's not, the amount of miles depends on how much tread you lost
m is indepdent
8 = x / 12.8
102.4 = x
Therefore x = 102.4
Answer:

Step-by-step Explanation:
Angle of depression is congruent to angle of elevation.
Therefore, angle of elevation of the given figure, which is opposite to x is 25°.
Adjacent length = 11 yd
Opposite length = x
Trigonometric ratio formula for finding x is shown below:


Multiply both sides by 11 to solve for x


(to the nearest tenth)
That number in scientific notation is 1.26 x10^-5. The decimal up front has to be greater than 1, but less than 10. We move the decimal to the left to get that answer 5 times. That is what gets us 1.26 x10^-5.
Step-by-step explanation:
step 1. The segment x is made up of 2 equal lines which are connected in the middle to another segment 12 units long.
step 2. the intersection of these two segments must create a 90° angle because the two lines are equal.
step 3. The lower segments are identical to the upper segments.
step 4. therefore x = 11(2) = 22.
