Let b be the speed of the boat, and c be the speed of the current. Then:
20/b+c=2/3 hr
20/b-c=1 hr
2/3b+2/3c=20
b-c=20
Then:
b+c=30
b-c=20
2b=50
b=25 mph
c=5 mph

Answer:
12
Step-by-step explanation:
Use the Pythagorean theorem which is a^2 + b^2 = c^2
c is hypotenuse and a and b are the legs
we need to find a^2 so
a^2 + 16^2 = 20^2
a^22 + 256 = 400
then subtract 256 from 400
a^2 = 144
square root 144
= 12

Answer:
Graphs represent the mathematical connections or interrelationships between the different set of the data whereas the charts represent the diagrams where one can find the depicted information or the data. As mentioned earlier all type of graphs are charts, but on the flip side, not all charts are graphs.
Step-by-step explanation:
I got this from the site called graphs vs charts i hope that is helps
Answer:
<em>"Consecutive y-values change by multiplying previous value by a constant amount. So, the table represents an exponential function."</em>
Step-by-step explanation:
In reality, the table represents an exponential function instead of a linear function, since values on domain change arithmetically at constant rate, whereas values on range change geometrically at constant rate.
Correct phrase may be:<em> "Consecutive y-values change by multiplying previous value by a constant amount. So, the table represents an exponential function."</em>
