A bike was originally $240.00. The price was marked up 15%. What is the new price of the bike?,

Answers

Answer 1
Origina Price = $240 
Mark Up percentage = 15%
(15/100)*240
= $36
new price = $240 + $36
= $276
Answer 2
this is the answer
hope it helps :
first you should find that how much 15% of 240 is:
[tex] \frac{15}{100} = \frac{x}{240} \\ x = \frac{240 \times 15}{100} = \frac{3600}{100} = 36 [/tex]
15% of 240 is 36. then:
[tex]240 + 36 = 276[/tex]
the new price of the bike is $276

Given a polynomial f(x) of fifth degree and g(x) such that
1. a root at 3i
2. a root at 2+4sqrt(3)
3. a root at -1/3
and that f(1)=-7520
Find polynomial f(x) as a product of its factors.

Given the three roots, we can conclude that the two other roots are the conjugates, namely -3i and 2-4sqrt(3).
Since
(x+3i)(x-3i)=x^2+9, and
(x-2+4sqrt(3))(x-2-4sqrt(3)=x^2-4x-44
We conclude that polynomial f(x) has the form
f(x)=a(x^2+9)(x^2-4x-44)(3x+1)
where a is a constant to be determined.

Knowing that f(1)=-7520, we can substitute x=1 in f(x) to get
-7520=a(1^2+9)(1^2-4(1)-44)(3+1)=a(10)(-47)(4)
=>
a=-7520/(-1880)=4

Therefore the polynomial f(x) is defined as

f(x)=4(x^2+9)(x^2-4x-44)(3x+1)
or
f(x)=4(3x+1)(x^2+9)(x^2-4x-44)
The root at -1/3 means that (3x+1) is a factor.

The root at 3i means that (x -3i)*(x +3i) = (x^2 +9) is a factor.

The root at 2 +4√3 means that (x -2 -4√3)*(x -2 +4√3) = (x^2 -4x -44) is a factor.

Evaluated at x=1, the product of these factors is (4)*(10)*(-47) = -1880, so there is an additional factor of -7520/-1880 = 4.

The intercept form of the polynomial is
.. y = 4(3x +1)*(x^2 +9)*(x^2 -4x -44)

Juliana and Maria logged a total of 90 hours working for their dad. Juliana worked 2 hours more than three times as much as Maria. How many hours did Juliana work?

Answers

Answer:
Juliana worked 68 hours

Explanation:
Assume the hours logged by Juliana is x
Assume the hours logged by Maria is y

We are given that:
1- Total hours logged by both is 90. This means that:
x + y = 90 
This equation can be rewritten as:
x = 90 - y ...........> equation I

2- Juliana worked 2 hours more than 3 times as much as Maria. This means that:
x = 3y + 2 ...........> equation II

Substitute with equation I in equation II and solve for y as follows:
x = 3y + 2
90 - y = 3y + 2
88 = 4y
y = 22

Substitute with y in equation I to get x as follows:
x = 90 - y
x = 90 - 22
x = 68

Based on the above:
Hours logged by Juliana = x = 68 hours
Hours logged by Maria = y = 22 hours

Hope this helps :)

Let

x---------> the hours logged by Juliana

y--------->  the hours logged by Maria

we know that

[tex]x+y=90[/tex] ---------> equation [tex]1[/tex]

[tex]x=3y+2[/tex] ---------> equation [tex]2[/tex]

Substitute equation [tex]2[/tex] in equation [tex]1[/tex]

[tex](3y+2)+y=90[/tex]

[tex]4y+2=90[/tex]

[tex]4y=90-2[/tex]

[tex]4y=88[/tex]

[tex]y=88/4[/tex]

[tex]y=22\ hours[/tex]

Find the value of x

[tex]x=3y+2[/tex]

[tex]x=3*22+2[/tex]

[tex]x=68\ hours[/tex]

therefore

the answer is

Juliana worked [tex]68\ hours[/tex]

A bicycle store costs $1700 per month to operate. The store pays an average of $75 per month. The average selling price of each bicycle is $95. How many bicycles must the store sell each month to break even?

Answers

The formula in computing the break-even point is:

Break-even = fixed cost / contribution margin

The fixed cost is already given which is $1700 per month. To compute for the contribution margin, you have to deduct the average cost per month ($75) to the selling price of each bicycle ($95). The contribution margin is $20 ($95 - $75).

Substituting the amounts to the formula:

Break-even = $1,700/$20

                     = 85

Therefore, the store must sell 85 bicycles each month to break even.

Company A can produce 100 CPUs in 3 days while Company B can produce 150 CPUs in 4 days. If the two companies join forces, how many days would it take them to produce 1000 CPUs?

Answers

I'm guessing it's about 16 days.

Hope this helped!

Answer: They would need 15 days

Step-by-step explanation:

The data is:

Company A produce 100 CPUs in 3 days, so the rate per day is:

Ra = 100/3 CPUs per day: 33.33 CPUs per day.

Company B produce 150 CPUs in 4 days, then it produces:

Rb = 150/4 = 37.5 CPUs per day.

Then, if both companies work toggeter, they produce

Ra + Rb = 33.33 + 37.5 CPUs per day =  70.83 CPUs per day.

We want to know the number X of days needed to make 1000 CPUs, then we need to solve:

70.83*X = 1000

X = 1000/70.83 = 14.11 days, we could round it up to 15 days if we want to have a whole number.

A sign standing 6 feet tall is situated 18 feet away from a flag pole. at a certain time of day the sign's shadow is 3 feet long and the flagpole's shadow is 24 feet long. how tall is the flagpole?

Answers

Observe attached picture.

On picture we have:
A = height of flagpole = x ft
B = length of flagpole's shadow = 24 ft
C = height of sign = 6 ft
D = length of sign's shadow = 3 ft

When we draw a picture representing this problem we can also add another line marked in red. This way we can see that we have two right-angle triangles. We can see that both have same angle marked with α.

We can apply trigonometry rules to find height of flagpole.

From small triangle containing sign we can find tangens function:
[tex]tan \alpha = \frac{C}{D} [/tex]
Similarly we can do for large triangle containing flagpole:
[tex]tan \alpha = \frac{A}{B} [/tex]

We see that these two equations have same left sides. This means that their right sides must also be same:
[tex]\frac{C}{D} = \frac{A}{B}[/tex]
We can solve for A:
[tex]CB=AD \\ A= \frac{CB}{D} \\ A= \frac{6*24}{3} \\ A=48 ft[/tex]

Height of flagpole is 48 feet.

Answers

We'll use this trig identity
cos(x-y) = cos(x)cos(y) + sin(x)sin(y)
where in this case,
x = pi/3
y = pi/5

So,
cos(x-y) = cos(x)cos(y) + sin(x)sin(y)
cos(pi/3-pi/5) = cos(pi/3)cos(pi/5) + sin(pi/3)sin(pi/5)
cos(pi/3)cos(pi/5) + sin(pi/3)sin(pi/5) = cos(pi/3-pi/5)
cos(pi/3)cos(pi/5) + sin(pi/3)sin(pi/5) = cos(5pi/15-3pi/15)
cos(pi/3)cos(pi/5) + sin(pi/3)sin(pi/5) = cos(2pi/15)

The answer is cos(2pi/15) which can be written as [tex]\cos\left(\frac{2\pi}{15}\right)[/tex]

You can make a triangle with  6, 14 and 16 straws.

The answer is one triangle

Im assuming you are not allowed to stick together any of the straws


There is no way to make a triangle with numbers 2,8,14, nor 2,8,16, nor 2,14, and 16.  Using 6, 14, and 16 straws, you can form a triangle.

I'm guessing you're not supposed to stick any one of the straws together.  Kindly see the accompanying document for more information. As a result, B is represented by one triangle. All two sides add up to more than the third side. As a result, the difference between the two sides is less than the difference between the first and third sides.

Therefore, the final answer is "one triangle".

A right rectangular prism has a square base and a height of 9 feet. its volume, v, is 144 cubic feet. what is the length of s, the sides of the base?

Answers

Volume of the rectangular prism = base area x height

Given that the volume is 144 ft³ and height is 9 ft

volume = base area x height
144 = base area x 9
base area = 144 ÷ 9
base area = 16 ft²

The base is a square which means both sides are of the same length
area = length x length
16 = length²
length = √16
length = 4 ft

s, the side of the base is 4 ft

The length of the sides of the base of a rectangular prism is 4 feet.

Given that, a right rectangular prism has a square base and a height of 9 feet.

What is a rectangular prism?

A rectangular prism is a three-dimensional solid shape with six faces that including rectangular bases. A cuboid is also a rectangular prism. The cross-section of a cuboid and a rectangular prism is the same.

Volume of a rectangular prism = Area of a base × Height.

Here, the volume of a rectangular prism = 144 cubic feet

Area of base = Area of a square = s²

So, 144 = s² × 9

⇒ s² = 16

⇒ s = 4 feet

Therefore, the length of the sides of the base of a rectangular prism is 4 feet.

A room's length is 3 feet less than twice its width. The area of the room is 135 square feet. What are the room's dimensions?

Answers

A room's length is 3 feet less than twice its width. The area of the room is 135 sq feet. What are the room's dimensions?

Hope this helps:

A= L x W
135 = (2w-3)(W)
135 = (2w squared - 3W)
135 = 2w^2-3w
2w^2-3w-135 = 0
-----

Use the quadratic formula to get:
w = [3 +- sqrt(9 - 4*2*-135)]/4

Positive solution:
w = [3 + sqrt(1089)/4
w = [3 + 33]/4
w = 9 ft
L = 2W-3 = 2*9-3 = 15 ft.





If the width is w, the length is l = 2w-3.
The total area is length x width = w*(2w-3)
Solve
w*(2w-3)=135 to find w.
2w^2-3w-135=0

w = (3 +/- sqrt ( 9 +8*135))/4

The positive solution is
w = ( 3 + 33) /4 = 9 and then l = 15.

The dimensions of room are: Length = 15 feet and Width = 9 feet.

What is Algebra?

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

we have,

A room's length is 3 feet less than twice its width.

The area of the room is 135 square feet.

let the width be x then length = 2x - 3.

So, Area of Room

135 = l w

135 = x (2x- 3)

2x² - 3x - 135= 0

2x² + 15x - 18x - 135 = 0

x (2x+ 15) - 9 (2x- 15)= 0

(2x+ 15)(x- 9)=0

x= -15/2 or x= 9.

In the United States the speed limit signs are in miles per hour. Unfortunately, your speedometer only reads in km/hour. How fast are you allowed to go if the speed sign says 70 mph (rounded to the nearest hundredth)

Answers

The correct answer is 112.65 kph

Answer:

The speed limit will be 112.65 kph.

Step-by-step explanation:

In order to find how fast one can go when speed sign says 70mph and the speedometer reads in km per hour we convert mph to kmph.

The conversion unit is 1mph= 1.609344kph

So 70mph = 70x1.609344=112.6541kph

Or 70mph=112.65 kph

how many 1020 flats can fit on (2) 8'x4' tables?

Answers

32 flats will fit on 2 8' by 4' tables.

The dimensions of each 1020 flat is 11" by 22".  We will convert the measurements of the table to inches.  8(12) = 96".  4(12) = 48".  If we lay the longest edge of the flat side along the long edge of the table, 4 flats will fit along it with 8 inches left over.  This would put the smaller edge of the flat along the smaller edge of the table, which would allow for 4 rows of 4, or 16 flats on each table.  16*2=32 flats between both tables.

This works out the same if we turn the flats around.  Let the smaller edge of the flat, 11", be along the longer edge of the table, 96".  This would allow for 8 flats.   This puts the longer edge of the flat, 22", along the shorter edge of the table, 48"; this puts 2 rows of 8, which would be 16 flats on each table, for a total of 32 flats.
