Answer:

54

Step-by-step explanation:

The sum of given angles must be equal to 360°

3x° + 2x° + 90° = 360°

5x + 90 = 360

5x = 270 divide both sides by 5

x = 54

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

Answer:

the answer is

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

-424-(-58)

-366

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

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

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

Answer:

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!

Answer:

3.125 pounds of beef

Step-by-step explanation:

Set up a proportion where x is the number of pounds of beef needed to feed 10 people:

[tex]\frac{1.25}{4}[/tex] = [tex]\frac{x}{10}[/tex]

Cross multiply and solve for x:

12.5 = 4x

3.125 = x

So, to feed 10 people, she will need 3.125 pounds of beef

Given:

A polynomial has a root of −2.

To find:

The factor that will divide evenly into the polynomial.

Solution:

We know that, if c is a root of a polynomial P(x), then (x-c) is a factor of polynomial P(x).

we have,

-2 is a root of polynomial.

⇒ (x-(-2)) is a factor of polynomial.

⇒ (x+2) is a factor of polynomial.

⇒ (x+2) will divide the polynomial completely.

Therefore, the factor (x+2) will divide evenly into the polynomial.

The factors of a polynomial divide the polynomial evenly, without remainder

The factor of the polynomial is x + 2

The root of the polynomial is given as:

[tex]\mathbf{Root = -2}[/tex]

Assume the polynomial is a function of x.

i.e. the variable of the polynomial is x

Then the root can be represented as:

[tex]\mathbf{x= -2}[/tex]

Add 2 to both sides

[tex]\mathbf{x + 2= -2 +2}[/tex]

So, we have:

[tex]\mathbf{x + 2= 0}[/tex]

Hence, the factor of the polynomial is x + 2

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.

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.
