Total mass of the atoms=number of atoms * weight of an atom
Total mass of the atoms=(4.02*10²³)*(1.67*10⁻²⁴)=(4.02*1.67)*(10²³⁻²⁴)=
=6.7134*10⁻¹
Answer: 0.67 grams, because (4.02*1.67)*(10²³*10⁻²⁴)=6.7134*10⁻¹
The examples that describe some of the applications of <u><em>geometry</em></u> in <em>aeronautics</em> are:
A. designing a <u>new</u> aircraft
B. describing the <u>flight path</u> between take off and landing
D.<u> navigating</u> between two locations
<em>Aeronautics</em> is a field that deals with designing, functioning and uses of <u>aircraft</u> in air transportation system which include <em>aeroplanes, helicopters, jets</em> etc.
Geometry is a topic that deals with lines, angles, planes, coordinates, points etc, thus its <u>importance</u> to aeronautics. Thus, its various applications as this field is concerned can not be over-emphasized.
In the giving question, the examples that best describe how <em>geometry</em> can be use in <em>aeronautics</em> are:
- A. designing a new aircraft
- B. describing the flight path between take off and landing
- D. navigating between two locations

Percent formula : is/of = % / 100
what percent of 21.5 is 55.04...
% = x....because this is what we r looking for
is = 55.04
of = 21.5
now we sub into the formula
55.04 / 21.5 = x / 100
cross multiply because this is a proportion
(21.5)(x) = (100)(55.04)
21.5x = 5504
x = 5504 / 21.5
x = 256 <== so ur answer is 256%
Answer:
The surface area of the lower rectangle is 20cm x 4cm= 80 square cm
the surface area of the two triangles is 12 square centimetres
the surface area of one of the top rectangular faces is 20×5= 100 square centimetres
the surface area of the other is 20×3= 60 square centimetres
80+12+60+100=252 square centimetres is the surface area of the polyhydron
