From 1200 midnight to 6:00 am, the temperature decreased by 12°C. if the original temperature was 12°C, which expression can be used to represent the situation?
A
12-12
B
12-12
C 12-(-12)
D
-12 + (-12)

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base
