Answer: The sailboat is at a distance of 15 km from the port.
Step-by-step explanation: Given that a sail boat leaves port and sails 12 kilometers west and then 9 kilometers north.
We are to find the distance between the sailboat from the port in kilometers.
Since the directions west and north are at right-angles, we can visualize the movement of the sailboat in the form of a right-angled triangle as shown in the attached figure.
The sailboat moves leaves the port at P and reach O after sailing 12 km west. From point O, again it moves towards north 9 km and reach the point S.
PS = ?
Using the Pythagoras theorem, we have from right-angled triangle SOP,

Thus, the sailboat is at a distance of 15 km from the port.

Answer:
The local newspaper has letters to the editor from 80 people. If this number represents 2% of all of the newspaper's readers, how many readers does the newspaper have?
Step-by-step explanation:
2%ofx=80
or, 2/100 *X = 80
or, 2x =800
or, x = 400
I'm pretty sure this is what you have to do;
v=-16-47v
add 47v on the other side of the equal sign
47v=-16
then divide 47 on each side of the equal sign
47v÷47v=1v or just v
-16÷47=-0.3
v=-0.3
I think this is right.
Hope this helps
