5,000 because a coin has 2 sides so there is 50% chance flipping on tails.
Call the rate in still water vs;
upstream you have: vs-v=6/4
downstram you have: vs+v=6/3
where v is the rate with which the river flows.
rearranging:
vs-v=3/2
vs+v=2
from the second you have v=2-vs substitute into the first:
vs-2+vs=3/2
2vs=7/2
vs=7 mi/hr
Answer:-4(2x-5)
Step-by-step explanation:
-4(2x-5)
-4(2x)+(-4)(-5)
-8x+20
-8/-4x+20/-4
-4(2x-5)
Answer:
ET = 80/A^2
Step-by-step explanation:
First, isolate the variables that you need, which is E and T, using the two equations you were given.
EA = 8
E = 8/A (divide A on both sides to isolate E)
AT = 10
T = 10/A (divide A on both sides to isolate T)
Now, substitute.
ET --> (8/A) x (10/A) = 80/A^2
Always know the formula for volume prism because that shape is a prism.
Formula For PRISM: BH/2 x Height.
So then we are going to solve the triangle first... 7 x 22= 154/2= 77
Then multiply by the height which is 25.
77 x 25= 1,925.
So your answer should be 1,925 meters cubed. *Don't forget to write the measurement
*hope this helps
