It would be 12 ones it would be this because you have to add 7+ 5
They are. There are 12 inches in a foot. 5x12 does equal 60 so they are equal.
Answer:
1733.28
Step-by-step explanation:
we want to find the surface area of the cylinder
We are given:
diameter = 12in
height = 40in
formula to find surface area of a cylinder: SA = 2πr^2 + 2πrh (where h = height and r = radius)
in order to find the SA of a cylinder we need to know the radius
we are given that the diameter is 12
we can acquire the measure of the radius by dividing the diameter by 2 ( this is because the radius is equal to half of the diameter )
so r = 12/2 = 6
now to find the surface area,
we simply plug in the values of the radius and height into the SA of a cylinder formula
SA = 2πr^2 + 2πrh
r = 6
h = 40
( note it says use 3.14 for π )
substitute values
SA = 2(3.14)(6)^2 + 2(3.14)(6)(40)
if you plug this into a calculator you get that the surface area is 1,733.28
I can't graph the equation for you, but I can tell you where the points will be. The y-intercept is easy; 1/3×0=0 and 0-2= -2. One of your points (the y-intercept) should be at (0,-2). To find another point is slightly trickier, but all you have to do here is find a multiple of three. For the simplest one, go to 3 on the x-axis. Then, apply the equation, y=1/3x-2. Your second point should lay at (3,-1). Then, just connect those two points and extend them to show that the line is continuous. Hope I could help!
So paid160
75 percent off
100 percent=original
75 percent off=100-75=25%
160=25% of original cost
'of' means multiply
remember tha tpercent is parts out of 100 so
25%=25/100=1/4
160=1/4 times original cost
multily both sides by 4
640=original cost
answe ris $640 =original cost
