Answer:
<u>18</u>
Step-by-step explanation:
You basically have to do 13.5 divided by 0.75 (3/4) which equals 18
We calculate both velocities:
upstream 8 miles in 2 hours = 4 miles / hour
downstream 8 miles in 1 hour = 8 miles / hour
ps -stream speed = 4 mph
ps + stream speed = 8 mph
Adding both equations
2 ps = 12 mph
paddling speed = 6 mph
stream speed = 2 mph
Answer:
63%
Step-by-step explanation:
<em>From the question, we aim to find the percent increase in the tuition</em>
Given data
initial cost= $99 per credit hour
Final cost= $268 per credit hour
% increase= (Final - initial )/initial *100
substitute
% increase= (268- 99 )/268 *100
% increase= 169 /268 *100
% increase= 0.630*100
% increase= 63%
Hence the increase in the tuition from 1990 to 2003 is 63%
Answer:
4 units
Step-by-step explanation:
Distance like magnitude is simply a positive value
----------------------------
Since the y coordinate is the same
the distance is just the difference in the x coordinates
from -5 to -1 is a distance of 4
