Answer:
Solution A = 2100
Solution B = 700
Step-by-step explanation:
Given that:
Let :
Millimeter of solution A = a
Millimeter of solution B = b
% alcohol, solution A =. 20% = 0.2
% alcohol solution B, = 14% = 0.14
Resulting millimeter of. Alcohol = 518
a = 3b - - - (1)
0.2a + 0.14b = 518 - - - - (2)
Put a = 3b in (2)
0.2(3b) + 0.14b = 518
0.6b + 0.14b = 518
0.74b = 518
b = 518 / 0.74
b = 700
a = 3b
a = 3(700)
a = 2100
Answer:
what do we need to do with number 15
Step-by-step explanation:
Answer:
i think it's 20/8
Step-by-step explanation:
Y=mx+c
Parallel=> m=5
Y=5x+c
Sub (1,6)
6=5+c
=> c=1
=> equation is y=5x+1
That's the ratio of 4,126,532 to 1,000,000 so it's rational.
Here's a little factoid that I never see mentioned anywhere, but I think it can be really helpful to know:
==> Any number that you can WRITE DOWN COMPLETELY using digits (plus a decimal point or a fraction bar if you need them) is a rational number.
If " 4.126532 " is the whole thing, you sure nuff wrote it down, so it's rational.
