If the sales tax for the city of Los Angeles is 9.75%, how much tax would you pay for an item that costs 200?

Answer:

0.66304

Step-by-step explanation:

probability ( p ) = 0.4

number of games played ( n )  = 5

Find the Probability of winning at least 2 games

P( wining ) = 0.4.

P ( losing ) ( q )  = 1 - 0.4 = 0.6

x = 2 , 3 , 4 , 5

P ( at least 2 out of 5 ) = p( k=2) + p(k=3) + p(k=4) + p(k5 )

                                    =  0.3456 + 0.2304 + 0.0768 + 0.01024

                                    = 0.66304 ( using binomial distribution calculator )

Answer:

6ft

Step-by-step explanation:

This requires a little use of the Pythagorean Theorem.

The length of the leaning ladder is the hypothenuse of the right triangle formed by the wall and the ladder.

Hyp. = 10 ft Say this is C

The ladder height up the wall = 8 ft. Say this A.

We need to find the other leg, say B ,of the right triangle.

C^2 = A^2 + B^2

10^2 = 8^2 + B^2

100 = 64 + B^2 => B^2 = 100 - 64 = 36

B^2 = 36 so, B = 6 The positive square root since length is positive.

B = 6 ft This is how far the ladder bottom is from the wall.

Double Check: 10^2 = 8^2 + 6^2 or 100 = 64 + 36 Ok. As, it should. This check could be done mentally.

In addition, this is a Pythagorean Triple. (6, 8, 10).

Answer: 6 ft.

Answer:

[tex]-6x^5+8x^4-14x^3[/tex]

Step-by-step explanation:

[tex]-2x^3(3x^2-4x+7)[/tex]   Use distributive property

[tex]-2x^3[/tex] · [tex]3x^2[/tex] = [tex]-6x^5[/tex]      

[tex]-2x^3[/tex] · [tex]-4x[/tex] = [tex]8x^4[/tex]       Product becomes positive because of two negatives

[tex]-2x^3[/tex] · [tex]7[/tex] = [tex]-14x^3[/tex]

Group all of those numbers together (in order)

[tex]-6x^5+8x^4-14x^3[/tex]

Answer:

x = 16

y = 20

Step-by-step explanation:

the left part of the triangle can be solved first as it already has one angle and 1 side, we use trigonometry for this.

since we have 2 sides and 1 angle, to find the third side length we use the pythagoras theorem. a² + b² = c²

; 9² + 12² = c²

; 225 = c²

;√225 = c

; 15 = c

since we have all the lengths of the triangle, we can find out the angle opposite to the side length '9',

; [tex]\frac{Sin x}{9} = \frac{sin90}{15}[/tex]

; [tex]\frac{Sin 90}{15}[/tex] x 9 = Sinx

36.86 = x

now, we look at the triangle as a whole, the top angle being 90 degrees, we know that we have 36.86.

; 90 - 36.86 = 53.13

[tex]\frac{y}{Sin 90} = \frac{12}{Sin 36.86}[/tex]

; [tex]\frac{12}{sin 36.86}[/tex] x Sin 90 = 20

y = 20

again, since we have 2 sides of a right angled triangle we use a² + b² = c²

we arrange this formula since we have the hypotenuse

; 20² - 12² = 256

; √256 = x

; 16  = x

Answer:

4725 pesos

Step-by-step explanation:

The price p of an aluminum tube is jointly proportional to its radius r and the length l.

For joint variation, we have the expression:

p ∝rl

Hence

p = krl

Step 1

Solving for k

if a 12-foot pipe with 5-inch radius costs 5250 pesos,

5250 = k × 12 × 5

5250 = 60k

k = 5250/60

k = 87.5

Step 2

how much will be the cost of a 9-foot pipe with a 6-inch radius

We make use of the expression:

p = krl

p = 87.5 × 9 × 6

p = 4725 pesos

Therefore, the cost is = 4725 pesos

Answer:

Step-by-step explanation:

In order for a company to break even, it earns no profit but it also incurs no loss. In other words, set the quadratic equal to 0 and factor to find x.

If you factor this using the quadratic formula you will get that the number of cars sold for the company to neither earn nor lose money is 1 or 21. Right in the middle is where we will find the maximum value (the vertex). This max value will give us the number of cars sold, h, and its corresponding value, k.

To solve for h easily, use the formula

[tex]h=-\frac{b}{2a}[/tex] where a and b are the coefficients found in the standard form of a polynomial [tex]ax^2+bx+c[/tex]:

[tex]h=-\frac{44}{2(-2)}=11[/tex] and for k, use:

[tex]k=c-\frac{b^2}{4a}[/tex]:

[tex]k=-42-\frac{44^2}{4(-2)}=200[/tex]

This means our vertex is (11, 200) and in the context of our problem, we know that when the company sells 11,000 cars it makes a max profit of 200 million dollars.

Answer:

[tex]x = 7[/tex] --- toppings

[tex]y = 27[/tex] ---- amount

Step-by-step explanation:

Given

[tex]y \to\ amount[/tex]

[tex]x \to\ topping[/tex]

The first deal is:

[tex]y = 6 + 3x[/tex]

The second is:

[tex]y = 20 + x[/tex]

Required

The value of  x and y [for which both deals are equal]

We have:

[tex]y = 6 + 3x[/tex]

[tex]y = 20 + x[/tex]

Equate both

[tex]y=y[/tex]

So, we have:

[tex]6 + 3x = 20 + x[/tex]

Collect like terms

[tex]3x - x = 20 - 6[/tex]

[tex]2x =14[/tex]

Divide by 2

[tex]x = 7[/tex]

Substitute [tex]x = 7[/tex] in [tex]y = 20 + x[/tex]

[tex]y = 20 + 7[/tex]

[tex]y = 27[/tex]

Volume is a three-dimensional scalar quantity. The volume of the softball is 61.6 cubic inches.

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

Given that the diameter of the softball is 4.9 inches. Since the radius is half the diameter, therefore, the radius of the softball can be written as,

Radius = Diameter

           = 4.9 inches / 2

           = 2.45 inches

Now, the volume of the softball can be written as,

Volume of the softball = (4/3) × π × r³

                                  = (4/3) × π × (2.45 inches)³

                                  = 61.6 inches³

Hence, the volume of the softball is 61.6 cubic inches.
