Outline the steps for taking cross sections of a rectangular prism.

Mathematics
1 answer:
fgiga [73]3 years ago
7 0

Answer:

  • find a suitable cutting tool
  • cut the prism on the plane of interest

Step-by-step explanation:

A cross section is the intersection of a cut plane with the object of interest. In a classroom setting, we often try to do the cross sectioning mentally or with diagrams, rather than physically cutting anything. Sometimes, there is no substitute for actually performing the cut to see what the cross section looks like.

For certain samples that don't take kindly to cutting, we sometimes encase them in a block of material that helps them hold their shape during the process. Sometimes the "cutting" is performed by grinding away the portion of the material on one side of the cut plane.

Write and solve an equation to answer the question. 14 is what percent of 70?
slamgirl [31]

Answer:

20%

Step-by-step explanation:

An equation is 14=x/100*70 or 14=(x%)*70, either one works

solve for x:

  1. 14=x/100*70
  2. 14/70=x/100 (Divide each side by 70)
  3. 1/5=x/100 (Simplify 14/70)
  4. 100/5=x (Multiply each side by 100 to isolate x)
  5. x=20 (Simplify 100/5)
  6. 20% (Rewrite as a percent)

hope this helps!!

P(-3,-5) and Q(1, -3) represent points in a coordinate<br> plane. Find the midpoint of PQ.
Karolina [17]

Step by step explanation :

The two points are ,

  • P( -3 , -5)
  • Q (1 , -3)

We can find the midpoint by finding the median of x coordinate and y coordinate .

\tt\to Midpoint = \bigg(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\bigg)\\\\\tt\to Midpoint =\bigg(\dfrac{-3+1}{2},\dfrac{-5-3}{2}\bigg)\\\\\tt\to Midpoint = \bigg( \dfrac{-2}{2},\dfrac{-8}{2}\bigg) \\\\\sf\to\boxed{\orange{\tt Midpoint = (-1,-4)}}
