Marine fuel is a combination of gasoline and motor oil. The standard gasoline and oil mixture is about 98% gasoline and about 2%
Georgia [21]

Answer:

0.98g+ 0.02m= 7.1224 gallons standard mixture

0.96g+ 0.04m= 6.25 gallons break oil

3.92 gallons of gasoline  is required for  4 gallons the standard mixture

Step-by-step explanation:

If we have to use 6 gallons of gasoline this means that 98%= 6 gallons and 2% would be 6/98*2

Gasoline: Motor oil

6              :    x

98        : 2

Using the product rule

x= 6*2/98= 0.1224 gallons of motor oil is required.

Let the gasoline be represented by g and motor oil by m then for the standard oil the equation would be

0.98g+ 0.02m= 7.1224 gallons standard mixture

For break in oil

Gasoline: Motor oil

6              :    x

96        : 4

Using the product rule

x= 6*4/96= 0.25 gallons of motor oil is required.

Let the gasoline be represented by g and motor oil by m then for the break oil the equation would be

0.96g+ 0.04m= 6.25 gallons break oil

Part b. For  4 gallons of the "break in" mixture

96% of the 4 gallons of the "break in" mixture is gasoline =  3.84 gallons of gasoline

4% of 4 = 0.16 gallons of motor oil

Now the standard mixture 4 gallons would contain 98 % of gasoline and 2 % of motor oil

98% of 4 gallons= 3.92 gallons of gasoline

2% of  4 gallons= 0.08 gallons of motor oil.

37 1/2% of _________ is 36, Please help show work I am really confused.
klio [65]

Before you start working on this problem, make sure you know
how to use a couple of the tools in your toolbox:

Tool #1:  37-1/2 percent means 0.375

Tool #2:  In math problems, "of" almost always means "times".

====================================

Your question says

                           "37-1/2 percent of blank is 36".

Translate it with your tools:

                                  0.375  times  blank  =  36 .

Divide each side by 0.375:              Blank = 36 / 0.375 .

Now grab your pencil or your calculator, and find the value of that
fraction (do the division).  Blank is equal to the value of the fraction.


To check your answer (find out whether it's correct):

Do exactly what the question says.

Multiply (0.375) times (your answer).  If you get 36,
then your answer is correct.  If not, it's not.
