Answer:
They should mix 49.95 pounds of Breakfast coffe and 35.05 pounds of Queen city coffe
Step-by-step explanation:
first we have to perform 2 equations one to represent the quantity of liters of coffee and another the price
b = liters of Breakfast coffe
q = liters of Queen city coffe
b + q = 80
b * 12.00 + q * 14.10 = 80 * 12.92
we solve for b in the first equation
b + q = 80
b = 80 - q
we replace b with (80 - q) in the second equation
b * 12.00 + q * 14.10 = 80 * 12.92
(80 - q) * 12.00 + q * 14.10 = 80 * 12.92
960 - 12q + 14.10q = 1033.6
-12q + 14.10q = 1033.6 - 960
2.10q = 73.6
q = 73.6/2.10
q = 35.05
we replace q with its value in the first equation
b = 80 - q
b = 80 - 35.05
b = 49.95
They should mix 49.95 pounds of Breakfast coffe and 35.05 pounds of Queen city coffe
B is true because it has the more money to earn
Answer:
<h3>A) </h3>
First were going to put our numbers in perspective.
÷ 
But to find the improper fraction, we have to <em>cross multiply</em> these numbers.
×
<em>7 x 5 = 35. </em>
<em>4 x 8 = 32.</em>
Now we have our<em> improper fraction </em>is 
<h3>B) </h3>
To turn our improper fraction into a <em>mixed number</em>, we will use <em>division</em>.
We know that the 32 can only go into 35 <u><em>one</em></u> time. We also know that the bottom number <em><u>always</u></em> stays the same. So our equation will look somewhat like this.
Now to fine the top number we will have to<em> subtract 35 from 32</em> because we already know that 32 can go into 35 <u><em>one</em></u> time, so <em>35 - 32 = 3</em>. So are mixed number will look like this.
This is our <em>answer!</em>
The instantaneous rate of change is simply equivalent to
the first derivative of the equation or function. We are given the equation of
Surface Area (A) with respect to side (x):
A = 6 x^2
Taking the first derivative of the equation:
dA = 12 x dx
dA / dx = 12 x
Now the term dA / dx is the instantaneous rate of change
in the surface area with respect to the side length. To get the rate of change
when the side x = a, simply plug this in into the equation:
rate of change = dA / dx = 12 x
so when x = a:
<span>rate of change = 12 a</span>
