Answer:
The amount of nuts is 16 kg and cereal mixture is 44 kg to obtain 60 kg of a mix that will sell for $1.40 per kg
Step-by-step explanation:
Let
x=nuts at $2.50 per kg
y=cereal at $1 per kg
x+y=60 kg (1)
2.50x+y=1.40(60) (2)
From (1)
x=60-y
Substitute x=60-y into (2)
2.50x+y=1.40(60)
2.50(60-y)+y=84
150-2.5y+y=84
-1.5y=84-150
-1.5y=-66
Divide both sides by -1.5
y=44 kg
Substitute y=44 into (1)
x+y=60
x+44=60
x=60-44
=16
x=16 kg
Question 1
Lets <em>convert these to decimals</em> first:
2 1/2 = 2.5
1/4 = 0.25
Now <em>divide</em> 2.5 by 0.25 to find how many scoops Zack uses.
If you divide correctly, you get <em>10</em>.
Now <em>multiply</em> this by two becuase Zack has TWO bird feeders.
So Zach uses <em>20 scoops</em> to fill both bird feeders.
------------------------------------------------------------------------------------------------------
Question 2
Let x be the variable for the scoops Zack needs for both bird feeders
x = 2 / x 2
------------------------------------------------------------------------------------------------------
Question 3
x = 2 / x 2
2 divided by = 10
x = 10 x2
10 multiplied by 2 is 20
So...
x = 20
------------------------------------------------------------------------------------------------------
Y=17400(1+0.025)^8 is your equation and with that you get $21200.21
Given parameters:
True value of measurement = 13.6in
Absolute error = 0.05in
Unknown:
Percent of error = ?
Solution:
Error is an inconsistency introduced into a particular data set or reading.
% error = x 100
% error = x 100 = 0.368%
Percent error is 0.368%
Answer;
32 pounds of the blend can be made
Explanation;
If light roast is 25%, then the other part will be 100-25 = 75%
Now the ratio of the light roast to the other part will be;
25% to 75% = 1 to 3
So if light toast is 8 pounds, the other part will be 3 * 8 = 24 pounds
So the amount of blend to be made will be 8 pounds + 24 pounds = 32 pounds
