I wasn't sure but I kept getting 12 oz and 240 oz. I'm pretty sure both of them are wrong 1 solutions
Answer 454820 by Alan3354(30993) on 2013-05-10 14:01:48 (Show Source):
You can put this solution on YOUR website!A 60 oz solution has a salt concentration of 20% . How many ounces of pure salt must be added to the solution to raise its concentration to 25% ?
----------------
Algebra method:
60*20 + x*100 = (60+x)*25
100x + 1200 = 25x + 1500
75x = 300
x = 4 oz
---------------
A logical method:
60*0.20 = 12 oz of salt --> 48 oz of water.
25% salt --> 75% water
To make 48 oz of water = 75% the total solution = 64 oz
64 - 60 = 4 oz

I have been having problems with this problem because for my
Mtan part I don't know if a my answer is right.
I got Mtan= -3/4 I just need help to find if this is correct
And if the slope is negative or positive.
------------------
The slope of the tangent at any point on a circle centered at the origin is
m = -x/y
m = +3/4 at point (3,-4)

You can put this solution on YOUR website!how do i know if a parabola opens right of left?
----------
Opening right or left --> the y term is 2nd order, eg x = y^2
If x & y have the same sign in that format it opens right since x increases as y increases.
-----------
If it's x = -y^2 it opens left since x decreases (more negative) as y increases.

----------------
The smallest angle is opposite the shortest side.
Use the Cosine Law.

Solve for the cosine, then the angle.

Linear_Equations_And_Systems_Word_Problems/746942: Can you help me solve I recently added some humming bird feeders to my yard. They are gorgeous and visit me all day long.
The recipe for hummingbird nectar is 4 cups of water for 1 cup sugar.
Write a function that can be used to determine how much sugar I would need to make any number of batches of nectar.
How much sugar do I need to make 4 batches? 11 batches?
Now do the same to determine how much water I would need to make the same numbers of batches. 1 solutions

Now do the same to determine how much water I would need to make the same numbers of batches.
---------------------
W = 4S or
S = W/4 both by volume.
------------------
If a batch is 1 Sugar and 4 Water,
1B = 1S + 4W
n batches = n*(S + 4W)
----------
I don't know why you'd make batches of liquid. Mix it in the 4:1 ratio and fill the feeders with however much they hold.
====================
The birds are migratory. You'll see as they pass thru, then they'll be gone for months.

F = (9/5)*C + 32
C = 15
Solve for F
