The map below shows the location of 3 houses where you had to do lawn work today. your truck gets 8 miles per gallon of gasoline, so you chose the shortest route from your house to the jobs and then back home, as shown below. if gas costs $1.52 per gallon, what was the total cost of the gas that you used today?

4.18 dollars to drive 20 miles

Step-by-step explanation:

3.80

Step-by-step explanation:

20 miles total X 1.52= 30.4

30.4 Divided by 8 miles to the Gallon

= $ 3.80

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

answer: what are the following choices
