Answer:
To perpendicular bisector of line segment WX. There are following steps:
1) Draw arcs or circles from points A and B on the both sides of WX.
2) Name the intersection points as W and X.
3) Use the straightedge to draw a line through points W and X.
4) Name the point as O
hence we have construct perpendicular bisector AB of WX which bisects at O.
Answer:
Step-by-step explanation:
First, start by converting 4 feet to inches. Note that 1 foot = 12 inches.
Set up a unit converter:
The ft cancel out leaving us with:
Now, we can set up a scale factor...
Answer:
5 km/h
Step-by-step explanation:
In this problem, Lashonda swam 4 km against the current. So the distance covered in this case is
Calling the velocity of Lahonda without the current, and
the velocity of the current, in this situation Lahonda's velocity is
So we can write:
where is the time taken to cover the distance.
When Lashonda swims with the current, her velocity is
So we can write
where
is the distance covered in this case, and
the time taken.
The velocity of the current is
Since Lashonad takes the same time to cover the two distances,
So we can write
And solving for v, we find Lashonda's velocity without the current:
