Answer:
Oh, how morbid these interest problems are.
Are you asking how much they would recieve in a year?
If so:
40000/100=400
400*60=$24000 a year
Don't let fractions fool you.

of a tank in

an hour is equal to:
1/12 of a tank in 20 minutes.
Thus we know in an hour, an oil company can fill 3/12 of a tank (60 minutes in an hour).
3 x 4 = 12, and 12/12 = 1(a whole tank), so we multiply 1 (hour) by 4.
Our answer is that it takes 4 hours to fill a tank.
Y=1/3x+c as 1/3 is the gradient/slope
Plug in the coordinates into the equation
-2= 1/3*(1) +c
C=-2-1/3
C=-7/3
Y= 1/3x-7/3
Step-by-step explanation:
app it's a standard 30 60 90 triangle. there are rules for this.
x = 3
y = 6
