It would be false since none of them are equal to 1.
0.1
the 0 is in the thousandths place plus the 2 os next to is since 2<5 it is 0
Answer: Choice C) 124 square cm
------------------------------------------------------------------
Explanation:
Let's calculate the area of the trapezoid shown
b1 and b2 are the parallel bases; h is the height of the 2D trapezoid
b1 = 2
b2 = 5
h = 1.5
A = h*(b1+b2)/2
A = 1.5*(2+5)/2
A = 1.5*7/2
A = 10.5/2
A = 5.25
The area of one 2D trapezoid is 5.25 sq cm
There are two of these trapezoids that form the base faces of the trapezoidal prism. So the total base area is 2*5.25 = 10.5 sq cm
Keep this value (10.5) in mind. We'll use it later.
------------
Now onto the lateral surface area (LSA)
It turns out that the formula for the LSA is
LSA = p*d
where
p = perimeter of the trapezoid shown
d = depth or height of the 3D trapezoid (I'm not using h as it was used earlier)
This formula works for any polygonal base. It doesn't have to be a trapezoid.
In this case the perimeter is,
p = 1.7+2+2.65+5
p = 11.35
So
LSA = p*d
LSA = 11.35*10
LSA = 113.5
Add this LSA to the base area found earlier
10.5+113.5 = 124
The total surface area is 124 square cm
Answer:
As the number of sides increases, the measures of the angles increase
see the explanation
Step-by-step explanation:
we know that
The measure of the interior angle in a regular polygon is equal to
where
n is the number of sides of the regular polygon
x is the measure of the interior angle in a regular polygon
we have that
<u><em>Examples</em></u>
<em>A triangle</em>
n=3 sides
<em>A square</em>
n=4 sides
<em>A pentagon</em>
n=5 sides
<em>A hexagon</em>
n=6 sides
so
n ----> 3,4,5,6...
x ----> 60°,90°,108°,120°,...
As the number of sides increases, the measures of the angles increase
The pattern is
<span>Halves, thirds, fourths, sixths, eighths (e.g., 1/2, 1/3, 1/4, 1/6, 1/8) these are some answers </span>
