Answer:
A) d = 48t, d in miles, t in hours
B)d = 32t, d in miles, t in hours
C)y = 8 mph
Step-by-step explanation:
16 miles in 20 mins = 48 mph
16 miles in 30 mins = 32 mph
The boat speed is the average = (48 + 32)/2 = 40 mph
The current is the difference = 8 mph

Answer:
The value of k is 4 and q is 16.
Step-by-step explanation:
First, you have to expand the brackets by applying :
Next, you have to do it by comparison :
Answer:
$11,170
Step-by-step explanation:
First you convert the percentage to decimal form out of 100 (which you divide)
3.9%/100 = 0.039
A = P(1 + rt)
A = 10000(1 + 0.039 * 3) ( * = multiplication)
I = $11,170 - 10,000 = $1,170
Which you should get $1,170.00 or $1,170 (which is pretty much the same thing)
Hope this helps!
