Answer:
Unit rate miles per day is, 3
Step-by-step explanation:
Unit rate are defined as the rate are expressed as quantity of 1 such that 2 miles per hour or 5 km per hour.
As per the given statement: A construction crew built 1/2 miles of road in 1/6 days
by unit rate definition;

After substituting the given values we have
⇒ 
or

Therefore, unit rate miles per day is, 3
Answer:
.
Step-by-step explanation:
A line that goes through
and
where
would have a slope of
.
The slope of the line that goes through
and
would thus be:
.
Two lines in a cartesian plane are perpendicular to one another if and only if the product of their slopes is
.
Thus, if
and
denote the slope of the first and second lines in this question,
since the two lines are perpendicular to one another. Since
, the slope of the first line would be:
.
Given that the first line goes through the point
, the point-slope equation of that line would be:
.
.
Substitute in
to find the
-coordinate of the point in question:
.
Answer:
4=H
Step-by-step explanation:
H is unknown
180=4x7x5+2x5xH
180=140+10H
40=10H
4=H
-12 + 18 = 70 - 64 or(-12+18)+(6*12)-2
165/3=55 mph
650/55=h
650/(165/3)=h
(650*3)/165=h
3/165=h/650
h/650=3/165
so it is the third option
