The nurse needs to mix 2% solution with 10% solution to get 10 ml of the prescribed 6% solution. What amount of each solution do

xenn [34]

<em>Volumes of 2% Solution = </em><em>5 ml</em>

<em>Volumes of 10% Solution = </em><em>5 ml</em>

$\texttt{ }$

<h3>Further explanation</h3>

Simultaneous Linear Equations could be solved by using several methods such as :

<em>Elimination Method</em>
<em>Substitution Method</em>
<em>Graph Method</em>

If we have two linear equations with 2 variables x and y , then we need to find the value of x and y that satisfying the two equations simultaneously.

Let us tackle the problem!

$\texttt{ }$

<em>Volumes of 2% Solution = x</em>

<em>Volumes of 10% Solution = y</em>

$\texttt{ }$

<em>Total Volume = 10 ml</em>

$\boxed{x + y = 10}$ → <em>Equation 1</em>

$\texttt{ }$

<em>The nurse needs to mix 2% solution with 10% solution to get 10 ml of the prescribed 6% solution</em>.

$2 \% x + 10 \% y = 6 \% (10)$

$2x + 10y = 6(10)$

$\boxed{x + 5y = 30}$ → <em>Equation 2</em>

$\texttt{ }$

<em>Equation 1 - Equation 2:</em>

$( x + y ) - ( x + 5y ) = 10 - 30$

$-4y = -20$

$y = -20 \div -4$

$y = 5 \texttt{ ml}$

$\texttt{ }$

$x + y = 10$

$x + 5 = 10$

$x = 5 \texttt{ ml}$

$\texttt{ }$

<h2>Conclusion:</h2>

<em>Volumes of 2% Solution = </em><em>5 ml</em>

<em>Volumes of 10% Solution = </em><em>5 ml</em>

$\texttt{ }$

The functions f and g are defined by f: x = 4 - x and g: x = hx² + k. If the composite function gf is given by gf: x + 2x² - 16x

kozerog [31]

Answer:

Step-by-step explanation:

f(x) = 4-x

g(x) = h $x^{2}$ +k

g(f(x)) = 2 $x^{2}$ -16x+26

so put f(x) in g(x)

h $(4-x)^{2}$ +k

h((4-x)(4-x) + k

h( $x^{2}$ -8x+16)+k

if h = 2 , then

2 $x^{2}$ -16x+32 + k

and we want 26 instead of 32 so subtract 6 so K = (-6)

2 $x^{2}$ -16x+32 + (-6)

2 $x^{2}$ -16x+32 - 6

2 $x^{2}$ -16x+26

h=2

k=(-6)

marishachu [46]

Answer:

$2875

Step-by-step explanation:

If the member ship costs 25 a month multiply it by 100 to find the amount of money made last month so 100*25=2500 to find the new amount take 100 add 40 and subtract 15 to find the number of people subscribed which is 115 multiply by 25 to get the total profit of 2875.
