Ten people board an airplane that has 13 aisle seats. In how many ways can they be seated if they all select aisle seats?

Answer:

Step-by-step explanation:

The answer is 1 and 3

We can use a scientific calculator or look up the sine of 25 degrees in a table of trigonometric values. The answer would be approximately 2.13 cm.

A right angle triangle is a triangle in which one of the angles is equal to 90 degrees. In other words, it is a triangle in which one angle is a "right angle." Right angle triangles are commonly used in geometry and trigonometry, and they play a crucial role in many real-world applications, such as surveying, construction, and navigation.

In a right triangle, the length of one side can be found using the sine function. The sine of an angle in a right triangle is defined as the ratio of the length of the opposite side to the length of the hypotenuse. In this case, the angle MNO is 25 degrees, so we can write the following equation to find the length of side MN:

MN = NO * sin(25°) = 4 cm * sin(25°)

To find the numerical value of MN, we can use a scientific calculator or look up the sine of 25 degrees in a table of trigonometric values. The answer would be approximately 2.13 cm.

Answer:C and D

Step-by-step explanation:

Answer:

ok so the answer would be h

Step-by-step explanation:

so basically the ratio is 4:2 -1:2 so purple is 2 and orange is 4. meaning purple is half of the orange. that ratio stays the same. if you were to multiply puplr by 60 you get 120. and if you multiply 4 by 60 you get 240. which 240 divided by 120 is 2 meaning h is the right answer choice.

The correct observation is Spinner 1 would land on orange the same number of times that Spinner 2 would land on purple.

The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.

Given:

Total times spined = 60

Spinner 1 land on orange out 60 times

= 4/20 x 60

= 1/5 x 60

= 12

Spinner 2 land on Purple out 60 times

= 2/10 x 60

= 1/5 x 60

= 12

Hence, Spinner 1 would land on orange the same number of times that Spinner 2 would land on purple.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

the side "?" is the Adjacent side (Adj)  and we are given the angle and the Hypontenuse ( long side) (Hyp)  of this triangle

so use CAH

cos(75) =  Adj / 8

algebra to solve for the Adj side (which is the "?" for this problem )

8*cos(75) = Adj

2.07055 = Adj

so the "?" is  2.1 ft ( rounded to the nearest 10th )

The area of the shade is 12 feet

Step-by-step explanation:

To find the area you would do 6 * 4 which equals 24 but with every triangle you have to cut the area in half so the actual answer would be 12 feet

Answer:

1.575 × 10^6 gallons

Step-by-step explanation:

1.25 × 10^6 = 1.25 × 1,000,000 = 1,250,000 gals.

Dolphin tank = 325,000 gals.

total vol. = 1,250,000 + 325,000 = 1,575,000 gals.

scientific notation = 1.575 × 10^6 gallons

Answer:

x = 3.2

Step-by-step explanation:

Apply pythagorean theorem, c² = a² + b²

Where,

c is the hypotenuse/longest side = √(10² - 9²) ≈ 4.4

a = x

b = 3

Substitute

4.4² = x² + 3²

19.36 = x² + 9

x² = 19.36 - 9

x² = 10.36

x = √10.36

x = 3.2 (nearest tenth)

It's asking you what the probablitiy of a red car is.

Since this looks like a test/homework, I'll give some hints.

Let's say that SUV's and car's are x.

Out of x, 60 percent is cars.

Let's call the amount of cars we have y.

Out of y amount car's, 15 percent is red.

It's asking that if you randomely chose a car, what the probability would be if you got a non-red car.

Of course, this problem only needs one variable, but for the sake of simplicity, I added 2.

Answer:

the far left one

Step-by-step explanation:

Answer:

When an expression can be viewed as the difference of two perfect squares, i.e. a²-b², then we can factor it as (a+b)(a-b). For example, x²-25 can be factored as (x+5)(x-5). This method is based on the pattern (a+b)(a-b)=a²-b², which can be verified by expanding the parentheses in (a+b)(a-b).

Answer:

$647.25

Step-by-step explanation:

Twenty-five percent off the regular $800 price comes to 0.75($800), or $600 (after the discount).

Calculating the 7.875% sales tax and adding it in, we find that the final price to be paid is (1 + .07875)($600), or $647.25.
