Answer:
10 metal and 20 plastic
Step-by-step explanation:
10 x 25 is 250, 20 x 10 is 200 and 250 + 200 is 450
To find avg downstream is 39/3 = 13 mph
upstream is 20/4 = 5mph
the average of the 2 is the still water speed which is 8 mph
2^t =38
take the log of each side
log ( 2^t) = log (38)
the exponent gets multiplies
t log (2) = log (38)
divide by log 2
t = log(38)/log (2)
t≈5.2479
The answer is c! hope it helps, can i have brainliest?? im so close to leveling up
Answer:
Step-by-step explanation: 3x-5+13+6= 3x+1+13= 3x+14(simplified) If you graph this the y intercept is 14 the growth is 3. I don't think it can be solved. 3x is not compatible when solving for are of a triangle unless you are trying to solve for x and you already have the area. Yes this is insolvable
