Answer:
0.6 km/hr
Step-by-step explanation:
Speed downstream: 13/5= 2.6 km/hr
Speed upstream: 7/5= 1.4 km/hr
Therefore, Velocity of current is: 1/2 (2.6-1.4) km/hr = 1/2(1.2) km/hr
Answer:
<u>Has the form y = kx</u>
( y = 0.11x)
(y = 0.04x)
<u>Can be put into form y = kx</u>
(z/x = 9)
<u>Other</u>
(5 = xy)
( x = y/2)
Step-by-step explanation:
<u>y = kx</u>
( y = 0.11x)
(y = 0.04x)
<u>kx = y</u>
(z/x = 9)
-----------
( x = y/2 )
( x - 5 = y)
(5 = xy)
Answer:
C. The set of rational numbers
Step-by-step explanation:
Don't listen to the other person. I trusted them and got the answer wrong. I just got the question and guessed the second time. I fortunately got the answer right. Good luck! :) <3
You have to use Pythagoras' theorem for this!
The triangle formed is 6 units across, and 8 units down, which means we can form an equation like this:
a^2 + b^2 = c^2
6^2 + 8^2 = c^2
36 + 64 = c^2
100 = c^2
c = 10.
The answer is 10 :)
