Answer:
eq: s= 5w + 3
Step-by-step explanation:
independent: number of weeks
dependent: amount of stickers
the amount of stickers depend on how many weeks pass by :) (English is my second language so I may write weird)
Answer (Please vote me Brainliest if this helps!):
The answer is D
Step-by-step explanation:
Lets start off with the square roots:
= 4
= 
= 4.24264...
Mixed fraction:
= 4.667
Therefore the answer is D.
If Sandra mixes <em>x</em> L of 65% solution with <em>y</em> L of 90% solution, then the resulting mixture has a total volume of
<em>x</em> + <em>y</em> = 500
litres, and it contains
0.65<em>x</em> + 0.90<em>y</em> = 0.75 (500) = 375
litres of alcohol.
Solve the first equation for <em>y</em> :
<em>y</em> = 500 - <em>x</em>
<em />
Substitute this into the second equation and solve for <em>x</em> :
0.65<em>x</em> + 0.90 (500 - <em>x</em>) = 375
0.65<em>x</em> + 450 - 0.90<em>x</em> = 375
75 = 0.25<em>x</em>
<em>x</em> = 300
Solve for <em>y</em> :
<em>y</em> = 500 - 300
<em>y</em> = 200
So, Sandra should mix 300 L of 65% solution with 200 L of 90% solution.
A, B, D are functions.
(First, second, and fourth response)
You can see which is function since for everyone input only has one value. You can also use the vertical line test.
