Ok I’ll break this down so it’s easier to understand:
So you start of with $80
The first step is to find 20% off
An easy way to find 20% is to divide it by 5.
80/5= 16
And since it’s 20% OFF we subtract 16 from 80
80-16= 64
Next we need to do the coupon
It is $5 off so
64-5= 59
And finally the rebate which is $2
59-2= 57
Answer:
57
375L-240L=135L
135÷0.6=81
The pump must work for 81 min or 1hr and 21 min until the tank reaches 240L
Answer: y = -1/3x + 10
Step-by-step explanation:
To make it perpendicular change the reciprocals
So instead of 3x it'll be -1/3x and so it passes through the given points
plug the points
8 = -1/3(6) + b
8 = -2 + b
add 2 to both sides
10 = b
so the equation of a line thats perpendicular to y=-3x-10 and passes through
points (6,8) is
y = -1/3x + 10
