Answers

Answer 1
Answer:

The number of inches in 50.8 centimeters is 20 inches.

Given that, one inch is equivalent to 2.54 centimeters.

What is metric conversion?

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.

What is the solution of the system defined by y = -x + 5 and 5x + 2y = 14?

Answers

The two equations given in the question are
y = - x + 5
and
5x + 2y =14
Now we will have to put the value of y from the first equation in the second equation and then calculate.
5x + 2y = 14
5x + 2(-x + 5) = 14
5x - 2x + 10 = 14
3x = 14 - 10
3x = 4
x = 4/3
Now we have to put the value of x in the first equation for determining the value of y
y = - x + 5
   = - (4/3) + 5
   = (15 - 4)/3
   = 11/3
So the value of x is 4/3 and the value of y is 11/3.

The converse of a conditional statement is "If the sum of the exterior angles of a figure is 360°, then the figure is a polygon.” What is the inverse of the original conditional statement?

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°.

Answers

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.

The answer is D because the statement is saying it's not a polygon if the sum of the exterior angles is not 360 which is the opposite of the statement

In ΔTUV, the measure of ∠V=90°, the measure of ∠U=55°, and VT = 82 feet. Find the length of TU to the nearest tenth of a foot.

Answers

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;

sin \ \theta=(opp)/(hyp)

where \theta=55^(\circ), opp=82 and hyp =TU

Substituting the values, we get;

sin \ 55^(\circ)=(82)/(TU)

Simplifying, we get;

TU=(82)/(sin \ 55^(\circ))

TU=(82)/(0.819)

TU=100.12

Rounding off to the nearest tenth, we get;

TU=100.1

Thus, the length of TU is 100.1 feet.

Using the distributive property to find the product (y — 4)(y2 + 4y + 16) results in a polynomial of the form y3 + 4y2 + ay – 4y2 – ay – 64. What is the value of a in the polynomial?

Answers

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:

(y)(y^(2)+4y+16)= y^(3)+ 4y^(2) +16y\n(-4)(y^(2)+4y+16)=y^(2)-16y-64

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
