Step-by-step explanation:

The area of Desert A is 500,000 square miles and the area of Desert B is 100,000 square miles.

What is area?

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.

Area of a square is side × side.

Let the area of Desert A = x square miles

and the area of Desert B = y square miles

Given that, the area of Desert A is five times the area of Desert B,

i.e. x = 5y                         ...(1)

and the sum of their areas is 600,000 square miles,

i.e.  x + y = 600,000  square miles                  ...(2)

Putting equation (1) in (2), we get

         5y + y = 600,000

or        6y = 600,000  or      y =  100,000  square miles

Using equation (1),

  x = 5 × 100,000 = 500,000  square miles

Hence, the area of Desert A is 500,000 square miles and the area of Desert B is 100,000 square miles.

Answer: x = -1 y=3

Step-by-step explanation:

yeah just do AP algebra.2 then you'll know the answers

The answer to the equation is -3/2.

1.Remove parentheses from each side of the equation and combine similar phrases to make it simpler.

2.Identify the variable term on one side of the equation by adding or subtracting.

3.You can find the variable's value by multiplying or dividing.

Given equation is x²+ 3-2x= 1+ x² +5

Thus x² from both sides gets cancelled because x²-x²= 0

Now we get 3-2x = 6

-3 = 2x

On dividing by 2 we get,

A) Reflexive Property of Equality

Step-by-step explanation:

If you look at your reflection in a mirror, you see yourself! Likewise, by the Reflexive Property, any number is its own mirror image. Any number (such as a real number) is equal to itself!

What this means is that any number is the answer as no number is given. It could be 3m = 3n, 10m = 10n, or 85m - 85n as long as the number of "m" is the same to the number of "n."

Firstly, we want to start by drawing the triangles

We have this as follow;

For triangle HOT, we have;

We want to get the values of x and y firstly

Since both triangles are congruent, the order of the sides match

Hence, we have angle O and H equal

Thus, we have that;

Now, to find Y, we need the measure of angle N

Angle N is same as W which we already have as 5y+ 26

Substitute N for Y

Since all the angles of a triangle sum up to 180, we have it that;

Now, we want the measure of each of the angles;

1. W = N = 5y+ 26 = 5(13) + 26 = 91

2. H = O = 5x-1 = 5(9) - 1 = 44

3. Y = T = 4x + 9 = 4(9) + 9 = 45

The measure of the angle having the question mark, found using the law of sines is ? ≈ 140°

The law of sines states that the sine of an interior angle of a triangle is proportional to the the length of the side opposite to the angle.

The given parameters are;

The radius of circle A = 6.4

The radius of circle B = 4.0

The radius of circle C = 3.0

The measure of angle at C = 24°

The length of the segment AB = 6.4 + 4 = 10.4

According to the law of sines, we have;

[tex]\dfrac{sin(A)}{a} = \dfrac{sin(B)}{b} = \dfrac{sin(C)}{c}[/tex]

Where;

a = The length of the side opposite angle ∠A

b = The length of the side opposite angle ∠B

c = the length of the side opposite angle ∠C

From the diagram, the side opposite angle ∠C, is AB, which by comparison indicates that when side c = AB = 10.4

c = 10.4

Similarly, the side opposite angle ∠A = a = BC = 4 + 3 = 7

a = 7

The known information are therefore; ∠C = 24°, a = 7, c = 10.4

[tex]\dfrac{sin(A)}{a} = \dfrac{sin(C)}{c}[/tex]

[tex]\dfrac{sin(A)}{7} = \dfrac{sin(24^{\circ})}{10.4}[/tex]

[tex]sin(A) = \dfrac{sin(24^{\circ})}{10.4}\times 7[/tex]

[tex]\angle A = arcsine \left( \dfrac{sin(24^{\circ})}{10.4}\times 7\right)[/tex]

∠A + ∠B + ∠C = 180° (angle sum property of a triangle)

∠B = 180° - (∠A + ∠C)

Which gives;

[tex]\angle B = 180^{\circ} -\left(24^{\circ} + arcsine \left( \dfrac{sin(24^{\circ})}{10.4}\times 7\right)\right) \approx 140^{\circ}[/tex]

The measure of the angle is ∠B ≈ 140°

The mean number of unoccupied seats per flight during the past year will lie between 11.15 and 12.05.

What is mean in mathematics?

There are many mean types in maths, particularly in statistics. Each mean serves to condense a specific set of data, frequently so that the general magnitude and sign of the data set can be better understood.

The arithmetic mean, also referred to as "arithmetic average," is a calculation that divides the total number of values in a data collection by their sum to get the central tendency of that set of numbers.

a) Calculations:

Degrees of freedom = n - 1 = 225 - 1 = 224

For 224 degrees of freedom and 90% confidence interval,

Critical t value = 1.652

Hence,

90% confidence interval will be:

[tex]11.6 \pm 1.652*4.1/\sqrt{225}[/tex]

[tex]11.6 \pm 0.45[/tex]

(11.15, 12.05)

b) Interpretation:

We are 90% confident that the population mean number of unoccupied seats will lie between 11.15 and 12.05

c) Caution with interpretation:

In this scenario, individual confidence interval should be calculated rather than mean number of unoccupied seats since we can't generalize this interpretation for individual flights.

d) To narrow a confidence interval, we can either increase the sample size or can decrease the confidence level.

An approximation refers to anything which is similar to but not identical to something else.

Rounding can be used to approximate a number. Before performing the operations, an estimate can be approximated by rounding this same values within it.

For the given number;  

-16 + square root of 40 can be written as.

= -16 + √40

Find the factors of 40 by prime factorization;

40 = 2×2×2×5
