A pattern exists in the sum of the interior angles of polygons. The sum of the interior angles of a
triangle is 180°, of a quadrilateral is 360°, and of a pentagon (5 sides) is 540°. What is the sum of
the interior angles of a nonagon (9- sided shape)?

Answers

Answer 1

Answer:

1,620 degrees.

Step-by-step explanation:

It has a steady pattern. 180 x 2 = 360, which is quadrilateral. 180 x 3 = 540, which is a pentagon. so, 180 x 9 = 1,620

A $33.62
B. $219.22
C. $174.42
D. $42.22

Answers

Answer:

A $33.62

Step-by-step explanation:

To figure this out you have to take -92.80 and add 126.42 to get $33.62. Have a great day and LEAVE ME ALONE PLZ! <3

Answer:

-92.80+126.42=33.62

Step-by-step explanation

Since you owe $92.80 it would be a negative. So it would be like this.

126.42-92.80= 33.62

Or

-92.80+126.42=33.62

−112−(+312)−(−58)= what is the answer

Answers

Answer:

the answer is

-112-(+312)-(-58)

-424-(-58)

-366

After doing some mathematical operations, the resultant answer is -366.

What are mathematical operations?An operation is a mathematical function that transforms zero or more discrete input values into discrete output values. The complexity of the operation depends on how many operands there are. The rules that specify the order in which specific operations should be carried out in order to solve an expression are referred to as the order of operations. Parentheses, exponents, multiplication, division (from left to right), addition, and subtraction are the order of operations. (Left to Right) PEMDAS (from left to right).

So, −112−(+312)−(−58):
Now, evaluate as follows:

−112−(+312)−(−58)-112-312+58-424 + 58-366

Therefore, after doing some mathematical operations, the resultant answer is -366.

Answers

Answer:

Step-by-step explanation:

1). 3 - | x + 4 | = 10 No solutions

2). 1/2  | x | + 3 = 3 One solution x = 0

3). | x - 8 | - 4 = - 1 Two solutions x = 5 and x = 11

Step-by-step explanation:

i got it right with edmentum

The equation 3 - | x + 4 | = 10 doesn't have any solution and  1/2  | x | + 3 = 3 has one solution while  | x - 8 | - 4 = - 1  has two solution.

What is the equation?

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.

A formula known as an equation uses the same sign to denote the equality of two expressions.

In another word, the equation must be constrained with some constraints.

01) First equation

1/2  | x | + 3 = 3

1/2  | x | = 0

| x | = 0

x = 0 and -x = 0 ⇒ x = 0

So it has only one solution at x = 0.

02) Second equation

| x - 8 | - 4 = - 1

| x - 8 | = 3

-(x - 8) = 3 ⇒ x = 5 and (x - 8) = 3 ⇒ x = 11

So it has two answers at 5 and 11.

03) Third equation

3 - | x + 4 | = 10

In this no one solution is possible.

Two radar stations reconnoiter a plane at the same time. The angles

radar stations if the plane is at an altitude of 30 km?
km (round to two decimal places)
20
59
30 km
Enter the answer

Answers

Answer:

The distance apart of the two planes is either 100.45 km or 64.40 km

Step-by-step explanation:

The given parameters are;

The angle of elevation of the plane from the two radar stations are; 20° and 59°

The altitude of the plane = 30 km

The horizontal distance from each of the radar stations from the plane is given as follows;

[tex]tan(\theta) = \dfrac{Altitude \ of \ the \ plane}{The \ horizontal \ distance \ of \ radar \ station \ from \ the \ plane}[/tex]

Therefore, we have;

[tex]The \ horizontal \ distance \ of \ radar \ station \ from \ the \ plane = \dfrac{Altitude \ of \ the \ plane}{tan(\theta)}[/tex]For each of the given radar stations, and their elevations, we have;

[tex]The \ horizontal \ distance \ of \ the \ 1st \ radar \ station \ from \ the \ plane = \dfrac{30 \ km}{tan(20^{\circ})}[/tex]

[tex]The \ horizontal \ distance \ of \ the \ 2nd \ radar \ station \ from \ the \ plane = \dfrac{30 \ km}{tan(59^{\circ})}[/tex]

The distance between the two radar stations, d = The sum of their horizontal distances from the plane

Therefore;

[tex]d = \dfrac{30 \ km}{tan(20^{\circ})} + \dfrac{30 \ km}{tan(59^{\circ})} \approx 100.45 \ km[/tex]

However, when the radar stations are on the same side, we have;

The distance between the two radar stations, dₓ = The difference of their horizontal distances from the plane

[tex]d_x = \dfrac{30 \ km}{tan(20^{\circ})} - \dfrac{30 \ km}{tan(59^{\circ})} \approx 64.40 \ km[/tex]

The distance apart of the two planes is either 100.45 km or 64.40 km

Exponents

By Vicki Young

I open up my textbook when I first get out of bed,

Start studying those rules, just like my teacher said!

Recognizing bases, exponents, too.

Exponents must be positive, negatives won't do.

I've got to work these problems, I've got to find a way.

Oh, I feel frantic today!

I start to see a pattern to how these things are done.

I raise to zero power and the answer's always one.

The base just can't be zero - I must remember that.

Just three more rules to learn now and then I can relax.

I'll put it all together, I'll know it pretty soon.

Oh, I feel better at noon!

To multiply same bases, exponents I combine.

Dividing's just the opposite, but then I must decide

To subtract the smaller power, the base correctly place.

The power rule says multiply, parentheses erase.

I know I've got these rules now, I know I've got them right.

Oh, I feel lucky tonight!
