Answer:

x=40

Step-by-step explanation:

6x-5-4x=75

We move all terms to the left:

6x-5-4x-(75)=0

We add all the numbers together, and all the variables

2x-80=0

We move all terms containing x to the left, all other terms to the right

2x=80

x=80/2

x=40

Suppose that you have a square pyramid like the one pictured. Which plane section will produce a triangle? Question 6 options: A
arsen [322]

The plane that would produce a triangle is A, a cut parallel to the vertical axis, directly through the vertical axis.

<h3>What is a squared pyramid?</h3>

A square pyramid is a geometric shape having four triangles, five faces and a square.  

<h3>Properties of a squared pyramid</h3>
  • It has a five bases
  • It has four or greater equilateral triangular faces meeting above the base
  • All the edges, sides and angles are equal

Since the sides are equal, cutting parallel to the vertical axis forms a triangle.

Therefore, a cut parallel to the vertical axis, directly through the vertical axis would produce a triangle.

Find the surface area of the building - (not including what is on the ground, as if we were going to paint it)
Rufina [12.5K]

Answer:

204.4m

Step-by-step explanation:

formula for SA of a rectangle is 2lw+2lh+2hw

so it would be 2(6x5) +2(6x3)+2(5x3)=126m

formula for SA of a triangle is bh+2ls+lb

so it would be 5x2+2(6x3.2)+6x5=78.4m

then add 78.4+126=204.4m

Can someone help me!!! been stuck on this for a while!!
Natali5045456 [20]

Answer:

<em>Volume: Option A - Around 85.33 (in^3)</em>

Step-by-step explanation:

Let us take a look at the problem. Here we are given the circumference of the bowling ball, provided it is in the shape of a sphere.

Our first step can be to note the formula of circumference, applicable to both a sphere and a circle:

C = 2 * π * r  - Where r = radius

Now let us substitute the known value of the circumference as to solve for r, or the radius:

(8π) = 2πr

r = 8π/2π

r = 4

Now take a look at the spherical formula for volume of a sphere:

V = 4/3 * π * r^3 - Where r is yet again the radius

Let us substitute the known value of the radius as to solve for the volume, or in other words to solve for the answer:

V = 4/3 * π * (4)^3

V = 4/3 * π * 64

V = 256/3 * π

V = (Around) 85.33π (in)^3

*Don't forget the units
