The number of inches in 50.8 centimeters is 20 inches.
Given that, one inch is equivalent to 2.54 centimeters.
Metric Conversion refers to the conversion of the given units to desired units for any quantity to be measured. The different unit of measurement resulted in the introduction of the "Metric System".
Number of inches in 50.8 centimeters = 50.8/2.54
=20 inches
Therefore, the number of inches in 50.8 centimeters is 20 inches.

I do khan academy 2 but sorry the answer
A. If a figure is a polygon, then the sum of the exterior angles is 360°.
B. If the sum of the exterior angles of a figure is not 360°, then the figure is not a polygon.
C. If the sum of the exterior angles of a figure is 360°, then the figure is not a polygon.
D. If a figure is not a polygon, then the sum of the exterior angles is not 360°.
Answer:
The correct option is D.
Step-by-step explanation:
Converse statement : If the sum of the exterior angles of a figure is 360°, then the figure is a polygon.
Now, to form a converse statement, the conclusion becomes the hypothesis and the hypothesis becomes the conclusion.
So, to form the original statement of the given converse statement : Hypothesis will become conclusion and the conclusion becomes our hypothesis.
⇒ Original Statement : The figure is a polygon if the sum of the exterior angles of a figure is 360°.
Now to form the inverse we need the negation of both hypothesis and the conclusion.
Hence, The inverse of the original statement is : If a figure is not a polygon, then the sum of the exterior angles is not 360°.
Therefore, The correct option is D.
Given:
Given that ΔTUV is a right triangle. The measure of ∠V=90°, the measure of ∠U=55°, and VT = 82 feet.
We need to determine the length of TU.
Length of TU:
The length of TU can be determined using the trigonometric ratio.
Thus, we have;
where , and
Substituting the values, we get;
Simplifying, we get;
Rounding off to the nearest tenth, we get;
Thus, the length of TU is 100.1 feet.

Answer:
16
Step-by-step explanation:
Since this is a multiplication of the square of (y+4) by (y-4) the value of Y will be eliminated in the product, if you want to assure this you just need to do the multiplication, and to do so we just need to multiply feach factor in the binomial by the polynomial:
So now we know that the value for the Y is 16.
(y - 4)(y² + 4y + 16)
y³ + 4y² + 16y - 4y² -16y - 64
y³ + 4y² + ay - 4y² - ay - 64
a = 16
