Answer:The answer is 12.0321

Step-by-step explanation:

Step-by-step explanation:

100% = $8.00

1% = 100%/100 = 8/100 = $0.08

the price went up by $8.48 - $8.00 = $0.48.

how many % is this ?

as many % as 1% fits into this difference :

0.48 / 0.08 = 6%

the price increase was 6%.

The value of x in the right angle triangle is approximately 45 degrees.

The angle of the right angle triangle can be found as follows:

Therefore, let's find the hypotenuse side using Pythagoras theorem,

6² + 6² = c²

c² = 72

c = √72

c = 8.48528137424

c = 8.5 cm

Hence,

sin x = opposite / hypotenuse

sin x = 6 / 8.5

sin x = 0.70588235294

x = sin⁻¹ 0.70588235294

x = 44.9006818301

x = 45°

The number of green watches that were sold is 78

The given parameters are:

The number of watches can be represented as

Gold + Green + Blue + Red = 234

Substitute Blue = Green

Gold + Green + Green + Red = 234

Gold + 2 * Green + Red = 234

Substitute Red = 2 * Gold

Gold + 2 * Green + 2 * Gold = 234

Evaluate the like terms

2 * Green + 3 * Gold = 234

Make Gold the subject in Green = 3* Gold

Gold = Green/3

Substitute Gold = Green/3 in 2 * Green + 3 * Gold = 234

2 * Green + 3 * Green/3 = 234

Evaluate the product

2 * Green + Green = 234

Evaluate the sum

3 * Green = 234

Divide both sides by 3

Green = 78

Hence, The number of green watches that were sold is 78

19n+9u=7500 and 4u-n

Step-by-step explanation:

Answer:

Step-by-step explanation:

1. Given that $53000 represents 100% of the original cost. You know that 6.9% as a percentage is equivalent to 0.069 as a decimal.

Increase in price:

           = 53000 * 0.069

           = $3657

2. The question states that the price of the car model is increasing, so you must add the original cost to the increase in price.

Price of next model:

           = 53000 + 3657

           = $56657

Answer:

  29.05°

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to remind you of the relationship between trig functions and side lengths in a right triangle. In your triangle, the sides adjacent and opposite angle D are given. The relevant relation is ...

  Tan = Opposite/Adjacent

__

Using the given values, we have ...

  tan(D) = (25 ft)/(45 ft) = 5/9

The value of the angle is found using the inverse tangent function.

  D = arctan(5/9) ≈ 29.05°

The measure of angle D is about 29.05°.

Answer:

  ∠CBA =90°; ∠CAD =65°; ∠ACD =25°; ∠CBD = 65°

  ∠BWA = 130°; ∠AWD = 50°

Step-by-step explanation:

The diagonals of a rectangle divide the figure into two pairs of congruent isosceles triangles. The figure is symmetrical about both the vertical and horizontal centerlines. Each corner angle of the rectangle is 90°. Of course, the sum of angles in any of the triangles is 180°.

__

The above descriptions tell you ...

  ∠ABD =∠ACD =∠BAC =∠BDC = 25°

  ∠CBA =∠BCD =∠CDA =∠DAB = 90°

  ∠CAD =∠CBD =∠ACB =∠ADB = 90° -25° = 65°

  ∠BWA =∠CWD = 180° -25° -25° = 130°

  ∠AWD = ∠BWC = 180° -65° -65° = 50°

The straight-line distance between penny and Lisa is 70.1 feet if Lisa is laying on a towel at the beach, which is 50 feet from the base of the hotel.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

Let's suppose the distance between the Lisa and Penny is x feet.

We can draw a right-angle triangle for this situation.

As we can see in the right angle triangle.

tan54.5 = x/50  (from the right-angle triangle)

x = 50tan54.5

x = 70.09 ≈ 70.1 feet

Thus, the straight-line distance between penny and Lisa is 70.1 feet if Lisa is laying on a towel at the beach, which is 50 feet from the base of the hotel.

Perimeter

So if he wants to create a rectangle advertisement

The sum of length and breadth must be 80

If it's square

It should have side as 40in

Answer:

Below in bold.

Step-by-step explanation:

a = 16, b = 19 and c = 14.

By the Cosine Rule:

cos A = (a^2 - b^2 - c^2) / -2bc, so:

cos A  = ( 16^2  - 19^2 - 14^2) / (-2*19*14)

             =   -301 / - 532

             =  0.565789

m < A = 55.54 degrees.

Now Using the Sine Rule:

a / sin A = b / sin B

16 / sin 55.54 = 19/sin B

sin B = 19 * sin 55.54 / 16

         = 15.666 / 16

         = 0.979125

m < B = 78.27 degrees.

Finally

m < C = 180 - 55.54 - 78.27 = 46.19 degrees.

Answer:

x=2

Step-by-step explanation:

We must equate f(x)=g(x) ;

x+3=2x^2-3

2x^2-x-6=0, when we solve for x in this equation we get 2 solutions:

x=2, x=-1.5

Since -1.5 is not seen in the table, we consider the value 2.

At x=2 in the table both f(x) and g(x) have the same value 5 and proves f(x)=g(x) has a solution at x=2.

Answer:

x = 2

Step-by-step explanation:

Given:

f(x) = |x| + 3

g(x) = 2x² - 3

From inspection of the table, the equation f(x) = g(x) has a solution when

x = 2 as this is the only value of x when the two functions have the same value of 5.

See attached graph for proof.  The points of intersection are the solutions:  (-2, 5) and (2, 5).  (Since x = -2 is not in the given table, this is not included in the answer to this question).

The average number of skateboards produced per day last year is 310.

It's the probability curve of a continuous distribution that's most likely symmetric around the mean. On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.

We have:

The standard deviation of skateboards produced was 20 skateboards. They found they produced up to 280 skateboards on 93.32% of the days last year.

Z- score at 93.32% is -1.5

We know:

[tex]\rm Z = \dfrac{(x - \mu)}{\sigma}[/tex]

[tex]\rm -1.5 = \dfrac{(280 - \mu)}{20}[/tex]

μ = 280 + 30

μ = 310

Thus, the average number of skateboards produced per day last year is 310.

The area of square x will be one-fourth of the area of square y. Then the correct option is C.

It is a polygon with four sides. The total interior angle is 360 degrees. A square's opposite sides are parallel and all sides are equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.

There are two squares.

The perimeter of square x is half the perimeter of square y.

Let the side of the square x be a and the side length of the square y be b. Then we have

Perimeter x = Perimeter y / 2

              4a = 2b

              2a = b

Then the area of the square x will be

Area of square x = (2a)²

Area of square x = 4a²

Then the area of the square y will be

Area of square x = (b)²

Area of square x = b²

Then the area of square x will be one-fourth of the area of square y.

Thus, the correct option is C.
