Step-by-step explanation:

Answer:

x = 22, y = 11√3

Step-by-step explanation:

Here,

x is the Hypotenuse side

y is the adjacent side.

11 is the opposite side.

Formula : -

sin θ = Opposite side / Hypotenuse side

Here,

θ = 30

Note : -

The value of sin 30 = 1 / 2

1 / 2 = 11 / x

Cross multiply,

x * 1 = 2 * 11

x = 22

By Pythagoras theorem,

11² + y² = x²

11² + y² = 22²

y² = 22² - 11²

22² = 11² x 2²

11² = 11² x 1²

y² = 11² ( 2² - 1 )

y² = 11² x ( 4 - 1 )

y² = 11² x 3

Square root on both sides,

y = 11√3

The resulting equation that Kent has when he moves all the terms to one side of the equal sign is k² - 8k + 12 = 0

A quadratic function is a function that usually has a single variable and it is raised to the power of 2. An example is x² + 10x + 25 = 0

Given this equation: k + 12/k = 8

If both sides are multiplied by k, the equation becomes: k² + 12 = 8k

If all the terms are moved to one side of the equal sign: k² - 8k + 12 = 0

Answer: 279.43

Step-by-step explanation:

The area of the tent that she will need to waterproof is 279.43 feet².

The area of a three dimensional object on it's outer surface is called the surface area of the object.

Given a tent in the form of a triangular prism as given.

We have to find the surface area of the tent excluding the base.

There are 2 triangular faces and 2 rectangular faces.

Area of the prism that needs to waterproof = area of 2 rectangles + area of 2 triangles

Area of rectangles = 2 × 14 × 8 = 2 × 112 feet² = 224 feet²

Height of the triangular face = √(8² - 4²) = √48

Area of 2 triangles = 2 × 1/2 × 8 × (√48) = 8√48 feet²

Area needed to be waterproofed = 224 feet² + 8√48 feet² = 279.43 feet²

Hence the area of the tent is 279.43 feet².

Answer: 6.36lb

Step-by-step explanation:

Step-by-step explanation:

Total Weight of the package = weight of product + weight of box

Weight of empty box =0.88lb

Total weight of the box is =7.24lb

Let Weight of product inside box=w

Let wet of empty box =y

Total weight = F

Then,

F=y+w

Since F=7.24lb. y=0.88

Then, w=F-y

w=7.24-0.88

w=6.36lb

The weight of the product is 6.36lb

hope this helps :)

Step-by-step explanation:

x, x+2 are the two positive consecutive of integers (x + 2, because the minimum distance between 2 odd numbers is always 2, as there can never be 2 odd numbers directly following each other; and neither can even numbers, by the way).

(x+2)² = 2×x² - 1

x² + 4x + 4 = 2x² - 1

0 = x² - 4x - 5

we can solve this by factoring.

that means we need to find a and b so that

(x - a)(x - b) = x² - 4x - 5 = 0

and x = a and x = b are the 2 solutions of the quadratic equation.

x² - ax - bx + ab = x² - 4x - 5 = 0

x² - (a+b)x + ab = x² - 4x - 5 = 0

a+b = 4

ab = -5

that means that either a or b has to be 5 and the other -1.

so, the result is

(x - 5)(x + 1) = 0

x = 5

or

x = -1

are the possible solutions.

since we are only looking for positive integers, x = -1 is not a valid solution.

and only x = 5 remains as valid solution.

therefore, the 2 positive consecutive odd integers are

Step-by-step explanation:

The number  2√5×3√6 is irrational, number √42/√168 is rational as we know π is an irrational number but 22/7 is rational.

It is defined as the numbers in all real numbers which cannot be represented as rational numbers, in other words the irrational number cannot be expressed in the form of p/q form.

A rational number is a sort of real number that has the form p/q and does not equal zero.

= 2√5×3√6

= 6√30

= √1080 = 32.863353450309965

The number is irrational.

= √42/√168

= 1/2

The number is rational.

= 5(4√5 - 3√5)

= 5√5

= √125 = 11.180339887498949

The above number is irrational.

= √64/32

= 1/4

The above number is rational.

= (5√3—√3)/2√3

= 2

The above number is rational.

Similarly, we can find whether a number is irrational or rational

Thus, the number  2√5×3√6 is irrational, number √42/√168 is rational as we know π is an irrational number but 22/7 is rational.

Answer:

  about 1.3885 miles ≈ 7331 ft

Step-by-step explanation:

The height of the helicopter can be found using the tangent relation, which we know relates the sides and angles of a right triangle by ...

  Tan = Opposite/Adjacent

__

With reference to the attached diagram, the above relation can be used to find the lengths of AC and BC, which we know total 4 miles.

  tan(28°) = h/AC   ⇒   AC = h/tan(28°) = h·tan(90° -28°) = h·tan(62°)

  tan(45°) = h/BC   ⇒   BC = h/tan(45°) = h·tan(90° -45°) = h·tan(45°)

The total distance between A and B is then ...

  AB = AC +BC

  4 = h·tan(62°) +h·tan(45°) = h(tan(62°) +tan(45°))

Dividing by the coefficient of h, we have the value of h:

  h = 4/(tan(62°) +tan(45°)) = 4/(1.88073 +1) ≈ 1.38854 . . . . miles

In feet, that is ...

  (1.38854 mi)(5280 ft/mi) = 7331 ft

The height of the helicopter is 1.38854 miles, or 7331 feet.

The original Length is, 6500 m.

Length is the term used for identifying the size of an object or distance from one point to the other.

Given that 6% of a length is 390 m

Let original length be a

Therefore,  6% of a = 390

a*6/100 = 390

a = 390*100/6

a = 6500

Hence, The original Length is, 6500 m.

Answer:

P(greater than 4 or factor of 5) = 1/3

Step-by-step explanation:

→ let A be the set {the numbers greater than 4}

then A : {5 , 6}

p(A) = 2/6

→ let B be the set {the factors of 5}

then B : {1 , 5}

p(B) = 2/6

P(greater than 4 or factor of 5) = p(A∪B)

Formula =================

p(A∪B) = p(A) + p(B) - p(A∩B)

………………………………………………

A∩B : {5}

then

cardA∩B = 1

Then

p(A∩B) = 1/6

Finally :

p(A∪B) = p(A) + p(B) - p(A∩B)

            = 2/6 + 2/6 - 1/6

            = 3/6

            = 1/3
