As a large truck fills its gas tank, the volume of gas, in gallons, can be modeled with the linear function v = 4.8m + 8.2, wher
jek_recluse [69]

Step-by-step explanation:

Step one:

given data

we are told that the expression is

v = 4.8m + 8.2

where  v is the volume of gas and

            m is the number of minutes it has been filling.

Step two:

Required

<em>Asumming the volume is in Liters</em>

the interpretation of the terms in the expression for the volume

4.8 means that  for every minute 4.8L of gas enters the gas tank

hence the rate of filling is 4.8L/min

8.2 means that there is 8.2L of gas already in the tank before the filling started.

The average score on a biology test was 72.1 (1 repeats). write the average score using a fraction.
Yuri [45]
72 \frac{1}{9}  1÷9 = 111....   2÷9 = 222.... and so on.

The proof is a little more difficult.

Think of all those repeating ones as a variable - let's call it n

so n= .111111......... repeating

How can we get a single one of those ones to jump across the decimal and be on the left side.   We can multiply all of those ones by 10.

10n (ten times the original number) = 1.1111111  (ones still go on forever)

Now here is the interesting part.  Let's take all the repeating ones in the first number we made away from the second number.

10n = 1. 1111111......
<u>-  n  =  .  1111111....
</u>9n   = 1    (all of the repeaters are gone and only the one we moved to the left
                   of the decimal is left)

Now let's divide by 9 to get n by itself
<u>9n</u>   = <u>1
</u>9        9

And voila!   n = 1/9

So to repeat 72.111... written as a fraction is 72\frac{1}{9}
