If it was 60 miles round trip, each way was therefore 30 miles.
Let x represent the hours taken on the dry road. Slippery road was then 2x. 2x + x = 3x. 35 / 3 = 11.66… = x.
So, on the dry road, the car took 11.66… hours.
For the slippery one, 2 * 11.66… or 23.33… hours.
Convert to mph, shall we?
Dry road:
30 miles / 11.66… hours = 2.57… mph.
Slippery road:
30 miles / 23.33… hours = 1.28… mph.

Answer:
the height is 54.99 ft or 659.84 in
Step-by-step explanation:
We know that the sides of similar triangles are proportional, so we can write:
2 ft / 6 ft 3 in = x / 171 ft 10 in
Now what we must do first and pass everything to the same unit of measurement:
Knowing that 1 foot equals 12 inches:
6 ft 3 in = 6 ft * 12 in / ft + 3 in = 72 + 3 = 75 in
171 ft 10 in = 171 ft * 12 in / ft + 10 in = 2052 + 10 = 2062 in
2 ft = 2 ft * 12 in / ft = 24 in
replacing:
24 in / 75 in = x / 2062 in
x = 24 * 2062/75
x = 659.84 in
Or they would also be 659.84 in * 1 ft / 12 in = 54.99 ft
That is, the height is 54.99 ft or 659.84 in
The equation of a line that is perpendicular to y=7/5x+6 and passes through the point (2 -6) is:
Step-by-step explanation:
Given equation of line:
y=7/5x+6
The equation is in slope-intercept form. In this case, the co-efficient of x is the slope of the given line
So the slope will be: 7/5
As we know that the product of slopes of perpendicular lines is -1
The general form is:
Putting the value of slope
To find the value of b, putting the point (2,-6) in the equation
Putting the values of b and m
