Calculate (round two decimal places for final answer) 15l is approximately .

For this case we must make a conversion. We have that by definition 1 liter equals 0.264172 gallons.

So, making a rule of three we have to:

1L ----------------> 0.264172 gallons

15L --------------> x

Where:

x: Represents gallons equivalent to 15 liters.

Rounding out we have that 15 liters equals 3.96 gallons.

3.96 gallons

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total
