Copper: Nickel = 4:1
a) How much copper needed for 20 kg nickel
C:N = 4: 1
C:20 = 4:1
C/20 = 4/1 Cross Multiply
C*1 = 4*20
C = 80
80kg Copper would be needed.
b) How much Nickel would be needed for 20 kg of Copper
C:N = 4: 1
20:N = 4:1
20/N = 4/1 Cross Multiply
4*N = 1*20
4N = 20 Divide both sides by N.
N = 20/4 = 5
5kg Nickel would be needed.
Answer:
wht cube
Step-by-step explanation:
If you multiply 13.99x0.04=.5596
then you added
13.99+.5596=14.5496
And this is your answer
Answer:
no
Step-by-step explanation:
Simple....
you have:

to convert them into
improper fractions:
1.) Take whole number*denominator
(5*5=25)
2.) Take what you got...and
add the numerator
(25+2=27)
3.) Use the original denominator

Do the same to the other one...
2*13=26
26+10=36

Now..add...

But..you need a common denominator!


Now you can add!

When simplified....

Thus, your answer.
