Acube has a surface area of 486 square meters.

find the volume of the cube.

The surface area of a cube is:

A=6s^2 so we can say:

s=√(A/6)=(A/6)^(1/2)

The volume of  a cube is:

V=s^3, using s found above we have:

V=(A/6)^(1/2)^3

V=(A/6)^(3/2), and A=486 so

V=(486/6)^(3/2)

V=81^(3/2)

V=729 m^3

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

answer: the slope is equal -1.

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
