Answer:
x=60.56, x=-82.56
Step-by-step explanation:
Solve using quadratic formula
Formula is

0.05x^2 + 1.1x = 250
Subtract 250 on both sides
0.05x^2 + 1.1x - 250=0
a= 0.05, b=1.1 , c=-250
Plug in the values in the formula


Now make two equations , one with + and one with -
then we solve for x

x=60.56

x=-82.56
Answer:
or 
Step-by-step explanation:
The perpendicular slope is the opposite-reciprocal of the original slope:
Perpendicular slope of -2 is 
Write the equation in point-slope form (
):

Convert to slope-intercept form if needed:


One half is equal to 3/6.
One third is equal to 2/6.
After removing 600 litres from the tank, there is a decrease from 3/6 to 2/6
3/6-2/6=1/6
600 litres is 1/6 of the tank. Multiply by 6 to get the capacity of a full tank.
600*6=3600
The tank can hold 3600 litres.
