Find surface area
SA=2pir^2+2hpir
h=42
r=1.5
SA=2pi1.5^2+2(42)pi1.5
SA=4.5pi+126pi
SA=130.5pi square inches
area/areacoverdperspray≤numberofsprays
130.5pi/150
2.73
so buy 3 cans because you can't get 0.73 cans
A
Is %
=
of 100
x 6
=
550 100
cross multiply and divide
100x=3300
divide both sides by 100
x=33
Answer:
sqrt(-3)
Step-by-step explanation:
solve using sqrt( b^2 - 4ac)
substitute values from original equation to find discriminant
Answer:

Step-by-step explanation:

Step 1. Find the slope (by using the slope-formula)
m = slope




Step 2. Create the equation of a line that has a slope of 

Step 3. Find the y-intercept
To do this, use any of the two points and substitute their x and y values

point: 




Step 4. Write the equation in Slope-intercept form
