System
Solution
- p = m = 5 — 5 lb peanuts and 5 lb mixture
<h3>
Step-by-step explanation:</h3>
(a) Generally, the equations of interest are one that models the total amount of mixture, and one that models the amount of one of the constituents (or the ratio of constituents). Here, there are two constituents and we are given the desired ratio, so three different equations are possible describing the constituents of the mix.
For the total amount of mix:
... p + m = 10
For the quantity of peanuts in the mix:
... p + 0.2m = 0.6·10
For the quantity of almonds in the mix:
... 0.8m = 0.4·10
For the ratio of peanuts to almonds:
... (p +0.2m)/(0.8m) = 0.60/0.40
Any two (2) of these four (4) equations will serve as a system of equations that can be used to solve for the desired quantities. I like the third one because it is a "one-step" equation.
So, your system of equations could be ...
___
(b) Dividing the second equation by 0.8 gives
... m = 5
Using the first equation to find p, we have ...
... p + 5 = 10
... p = 5
5 lb of peanuts and 5 lb of mixture are required.
Answer:
right-handed gloves and 
left-handed gloves were sold.
Step-by-step explanation:
Given: In one month, 
gloves were sold for a total revenue of 
.
right-handed gloves cost 
and left-handed gloves cost 
.
To find: How much of each type of gloves did they sell?
Solution: Let they sell 
right-handed gloves, and 
left-handed gloves.
Now, cost of each right-handed gloves 
cost of each left-handed gloves 
Total revenue 
So, we get
Also, in a month gloves were sold.
So, we get
Now, from 
we get, 
.
Putting in equation 
, we get
Now, putting 
in equation , we get
Hence, right-handed gloves and left-handed gloves were sold.
SA = 4 * (pi) * r^2......solving for (pi)
divide both sides by 4r^2
SA / (4r^2) = (pi)
