Answer:
The total number of ways to answer = 32
Step-by-step explanation:
A quiz has five questions that can be answered as true or false.
Each question can be answered in two ways.
Lets take each question one by one.
The first question can be answered as true or false that is two ways.
Similarly each question answered in 2 ways.
To get the total number of ways, we have to multiply the number of ways for each question.
Hence the total number of questions =
= 32
We have 60 gallons of 20% antifreeze.
How much 70% antifreeze do we add to get 60% antifreeze?
We'll make "x" the gallons of 70% we must add.
.20 * 60 + .70 x = .60 * (60 + x)
12 + .70x = 36 + .60x
.10x = 24
x = 240 gallons of 70% antifreeze.
