Answer:

-15/16

Step-by-step explanation:

The sum of a geometric series with first term a1 is ...

S = a1/(1 -r)

Then the common ratio (r) is ...

r = 1 -a1/S

For the given values, the ratio is ...

r = 1 - 124/64 = -15/16

The common ratio is -15/16.

How many gallons of a 80% antifreeze solution must be mixed with 100 gallons of 20% antifreeze to get a mixture that is 70% a

Blababa [14]

To Find :

How many gallons of a 80% antifreeze solution must be mixed with 100 gallons of 20% antifreeze to get a mixture that is 70% antifreeze.

Solution :

Let, x gallons of 80% antifreeze solution is required :

So,

$(x \times 80) + ( 100 \times 20 ) = (x + 100 )\times 70\\\\8x + 200 = 7( x + 100)\\\\x = 500$

Therefore, 500 gallons of 80% antifreeze solution is required.
