The cost before tax for an order of CDs from Music & More store was $214.60. If the store ordered 20 equally priced CDs, and the total shipping and handling fee was $15.00, what was the cost of one CD?

Answers

Answer:

Cost of one CD = $9.98

Step-by-step explanation:

Total cost = $214.60

Total shipping and handling fee = $15.00

Number of CDs = 20

Cost of 20 CDs = Total cost - Total shipping and handling fee

= $214.60 - $15.00

= $199.60

Cost of one CD = $199.60 / 20

= $9.98

Cost of one CD = $9.98

$9.98

A snail climbs to the top of a coconut tree 18 meters high. In an hour it will climb 2 meters. But if it go 2 meters, it will slips down one meter. Then how long does it take for the snaik to reach the top of the coconut?

Answers

Answer:

The snail will reach the top of the coconut in 18 hours.

Step-by-step explanation:

If the snail will climb 2 meters in 1 hour but it will slip down one meter for every 2 meters climbed, then the distance traveled will be:

[tex] d = 2 m - 1 m = 1 m [/tex]

Since in 1 hour, it climbs 2 meters minus 1 meter, the time in which the snail will reach the top is:

[tex] t = \frac{1 h}{1 m}*18 m = 18 h [/tex]

Therefore, the snail will reach the top of the coconut in 18 hours.

A. Only the reaction rate would change.
B. The equilibrium constant would decrease.
C. The amount of NO and SO3 would increase.
D. The amount of NO2 and SO2 would increase.

Answers

Answer:

D. The amount of NO2 and SO2 would increase.

Step-by-step explanation:

This is an exothermic reaction as Heat is among the products. Increasing the temperature would lead to more products in the reaction system. In order for the system to annul this change, more reactants would be formed.

The correct option is;

D. The amount of NO2 and SO2 would increase.

Answer:

La probabilidad de que la pieza elegida sea defectuosa, P(D), 0.0385

La máquina con mayor probabilidad de haber producido la pieza defectuosa es A

Step-by-step explanation:

Sea D= "la pieza es defectuosa" y N= "la pieza no es defectuosa". La información del problema puede expresarse en el diagrama de árbol adjunto.

Para calcular la probabilidad de que la pieza elegida sea defectuosa, P(D), por la propiedad de la probabilidad total,

P(D) = P(A) · P(D/A) + P(B) · P(D/B) + P(C) · P(D/C) =

= 0.40 · 0.03 + 0.35 · 0.04 + 0.25 · 0.05 = 0.0385

Debemos calcular P(B/D). Por el teorema de Bayes,

P(B/D)= P(B) x P(D/B) / P(A) x P(D/A) + P(B) x P(D/B) +P(C) x P(D/C)

= 0.35 · 0.04 / 0.40 · 0.03 + 0.35 · 0.04 + 0.25 · 0.05

Calculamos P(A/D) y P(C/D), comparándolas con el valor de P(B/D) ya calculado. Aplicando el teorema de Bayes, obtenemos:

0.012

0.0385

P(A/D)= 0.311

P(B(D)=0.363

write an equation in slope-intercept form of the line perpendicular to y= -1/5x + 1/4 that passes through the point (3,4)

Answers

Answer: y=5x-11

Step-by-step explanation:

y=5x-11 is the equation of the line perpendicular to y= -1/5x + 1/4 that passes through the point (3,4).

What is Slope of Line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The given equation of line is y= -1/5x + 1/4

The slope of the perpendicular line is 5.

We need to find line perpendicular to y= -1/5x + 1/4 that passes through the point (3,4)

4=5(3)+b

-11=b

Hence, y=5x-11 is the equation of the line perpendicular to y= -1/5x + 1/4 that passes through the point (3,4).

An isosceles triangle has angle measures of (2x degrees) and (5x degrees). What are three possible angle measures of the triangle? Show all work.

Answers

Answer:

[tex]40^{\circ},\:40^{\circ},\: 100^{\circ}[/tex]

Step-by-step explanation:

The interior angles of any triangle always add up to [tex]180^{\circ}[/tex]. In an isosceles triangle, (at least) two sides are congruent and therefore their base angles are also congruent. We can then form the following equation:

[tex]2x+2x+5x=180[/tex], where [tex]x[/tex] is some constant.

Solving, we get:

[tex]9x=180,\\x=20[/tex]

Therefore, plugging our constant back in, our angles are:

[tex]2(20),\: 2(20), \: 5(20), \\\fbox{$40^{\circ},\:40^{\circ},\: 100^{\circ}$}[/tex].

Note this is only one group of possible angles. We could've also set the angle represented by [tex]5x[/tex] to be the pair of angles that are congruent, and depending on your definition of isosceles, each angle measure could be [tex]60^{\circ}[/tex] (equilateral).

Answer:

100, 40, 40

Step-by-step explanation:

First, do 2x+2x+5x because an isosceles triangle has two equal angles. We know that a triangle's total angle is 180 degrees so we do 180/9=20 x=20. Then multiply 2 by 20 to get 40. Then multiply 5 by 20 to get 100. So you get 40 40 100.

Dave found the blueprint of his house. It shows the hallway is 4 inches long. If the scale factor is 1 inch: 1.25 feet, then what is the length of the hallway in real life?

Answers

Answer:

5 feet

Step-by-step explanation:

The scale factor = 1 inch: 1.25 feet

The length of the Hally = 4 inches

The length of the hallway in real life is calculated as:

1 inch = 1.25 feet

4 inches = x feet

Cross Multiply

x feet = 4 × 1.25 feet

x feet = 5 feet

Therefore, the length of the Hallway in real life is 5 feet

Two cruise ships leave the same port with a 35° angle between their path. Cruise A is traveling at 18 miles per hour and Cruise B is traveling at 15 miles per hour. If they travel in a straight path, find the distance between the cruise ships after 2 hours

Answers

Answer:

[tex]20\:\mathrm{miles}[/tex]

Step-by-step explanation:

After travelling two hours, the two cruise ships form a triangle. One of the legs of this triangle will be the distance Cruise A travelled, and another will be the distance Cruise B travelled. We can find the distance they travel using:

[tex]s=\frac{d}{t}, d=s\cdot t[/tex]

Cruise A is travelling at 18 miles per hour for 2 hours. Therefore, Cruise A has travelled:

[tex]d=s\cdot t=18\cdot 2=36\:\mathrm{miles}[/tex]

Cruise B is travelling at 15 miles per hour for 2 hours. Therefore, Cruise B has travelled:

[tex]d=s\cdot t=15\cdot 2=30\:\mathrm{miles}[/tex]

Because we are given the angle between these legs, we can use the Law of Cosines to find the third leg. The Law of Cosines is given by:

[tex]c^2=a^2+b^2-2ab\cos C[/tex], where [tex]a[/tex], [tex]b[/tex], and [tex]c[/tex] are interchangeable. Let [tex]c[/tex] represent the distance between the two cruises. We have:

[tex]c^2=36^2+30^2-2\cdot36\cdot30\cdot \cos 35^{\circ},\\c^2=426.63,\\c\approx \fbox{$20\:\mathrm{miles}$}[/tex](one significant figure).

9514 1404 393

Answer:

20.7 miles

Step-by-step explanation:

The distance that A travels in the same direction as B is ...

(18 mi/h)(2 h)cos(35°) = 29.489 mi

So, the difference in distances in that direction is ...

(15 mi/h)(2 h) -29.489 mi = 0.511 mi

The distance A travels in the direction perpendicular to B is ...

(18 mi/h)(2 h)sin(35°) = 20.649 mi

So, the straight-line distance between the ships is the hypotenuse of the right triangle with these distances as legs:

AB = √(0.511² +20.649²) = √426.632 . . . miles

AB = 20.655 miles ≈ 20.7 miles . . . separation after 2 hours
