Answer:
Percent = 20%
Step-by-step explanation:
Since we have a decimal form of 2/10, we can turn it into percentage by multiplying 0.20 by 100.
=> 0.20 by 100
=> 20%
Therefore, 20% is our answer.

Answer:
<h2>Your answer would be <em><u>0.34</u></em></h2>
Step-by-step explanation:
first we add them altogether:
0.25+0.17+0.21+0.03 = 0.66
than we subtact the 0.66 from the whole (1) =
<u>1-0.66= 0.34</u>
Answer:
49.8 ft²
Step-by-step explanation:
the picture in the attached figure
given:
a=3, b=1 c=1.8
To know the surface area:
surface area of the figure=surface area of cube+surface area of triangular prism
first lets find out the area of cube and triangular prism.
surface area of cube=4*a²
surface area of cube= 4*3² => 36 ft²
surface area of triangular prism=2*[a*c]+2*[a*b/2] = 2*[3*1.8]+[3*1]
surface area of triangular prism=10.8 +3 = > 13.8 ft²
Therefore, surface area of the figure=36 ft²+13.8 ft²
surface area of the figure= 49.8 ft²
the answer is:
49.8 ft²
The Formula for the volume of a sphere is 
- r --> length of radius --> 2ft
<u>Volume</u> = 
The <u>volume is 33.51 cubic feet</u>
