Solve for d 6d -11/2 = 2d -13/2. Please answer quickly
Slav-nsk [51]

6d -11/2 = 2d -13/2

Subtract 2d from both sides

6d -11/2 - 2d = 2d -13/2 - 2d

Simplifying

4d -11/2 = -13/2

Add 11/2 to both sides

4d -11/2 + 11/2 = -13/2 + 11/2

Simplifying

4d = -2/2

4d = -1

Divide both sides by 4

4d/4 = -1/4

Simplifying

d = - 1/4

What is 6.3-2(1.5c+4.1)
ASHA 777 [7]
Expand\;-2\left(1.5c+4.1\right)
\mathrm{Distribute\:parentheses\:using}: \:a\left(b+c\right)=ab+ac
\;a=-2,\:b=1.5c,\:c=4.1

Simplify\;-2\cdot \:1.5c-2\cdot \:4.1 \ \textgreater \  \mathrm{Multiply\:the\:numbers:}\:2\cdot \:1.5=3
-3c-2\cdot \:4.1

\mathrm{Multiply\:the\:numbers:}\:2\cdot \:4.1=8.2 \ \textgreater \  -3c-8.2 \ \textgreater \  6.3-3c-8.2

\mathrm{Subtract\:the\:numbers:}\:6.3-8.2=-1.9 \ \textgreater \  -3c-1.9

Hope this helps!

Will all slices created by a slicing plane that passes through a sphere be the same size
Snowcat [4.5K]

Answer:

The suggestion proposed considering special cases, so that’s what we’ll do.

One special case we could consider is when x=0. If h=r, then we have a hemisphere. You may have learnt that the surface area of a sphere is 4πr2, so the answer in this case is 2πr2. Likewise, we can consider the most extreme cases: when h=2r, we get an area of 4πr2 (the entire sphere), and when h=0, we get zero area.

So if we do manage to get a general formula, we will be able to check it in these special cases.

Another possible idea when x=0 is to consider what happens when h is very small. In this case, the surface area looks a lot like a circle, but the radius of the circle does not seem particularly easy to work out, so maybe we’ll leave this one for a moment. (There are things we can do to approximate the radius using more advanced techniques, but they are currently beyond us.)

Another thing we could consider is the situation where h is very small. Then the part of the sphere between the planes looks very much like the frustum of a cone, and we know how to find the (surface) area of such a shape – see Cones.

If we recall our answer from that problem, we find the formulae for the surface area

π(R+r)s=π(R+r)hcosθ=π(R2−r2)sinθ.

Here, R is the radius of the base of the frustum, r is the radius of the top, h is the perpendicular height, s is the slant length and θ is the angle the slant makes with the vertical.
