The Eiffel Tower in Paris, France. Lizbeth is 5.5 feet tall. She looks up at an angle of elevation of 72° to see the top from 318 feet away. Based on her measurements, calculate the height of the Eiffel Tower. Round to the nearest hundredth of a foot.
Answer:
The height of the Eiffel Tower will be 318 feet.
Step-by-step explanation:
Please check the attached graph.
From the diagram, it is clear that Lizbeth is 5.5 ft tall, seeing the top from 318 feet away, making an angle of elevation to be 72⁰.
The diagram makes a right-angled triangle.
Given the angle = Ф = 72⁰ Adjacent = a = 5.5 ft Opposite = b = 318 ft Hypotenuse = the height of the Eiffel Tower = c ?
Pythagorean Theorem:
For a right-angled triangle, with sides 'a' and 'b', the hypotenuse 'c' is defined as:
[tex]c=\sqrt{a^2+b^2}[/tex]
[tex]a=5.5[/tex][tex]b=318[/tex][tex]c=\sqrt{5.5^2+318^2}[/tex]
[tex]c=318[/tex] feet
Therefore, the height of the Eiffel Tower will be 318 feet.

An order of beef nachos is $2.00 more than an order of
chicken nachos. You and your friends order 2 orders of chicken nachos and
one order of beef nachos for a total of $21.50. Determine the price of a
single order of chicken nachos.
Answer:
8.75
Step-by-step explanation:
(21.50/2)-2
Answer:
a single order of chicken nachos is $6.50
Step-by-step explanation:
Because 2 orders of chicken nachos is $13.00($6.50 times 2) and one order of beef nachos is $8.50, add the $13.00 and $8.50 and you get $21.50.

During an online sale, you buy three sweatshirts and two pairs of sweatpants for $85.50. Later you buy three more sweatshirts and four more pairs of sweatpants for $123. (You can never have too many sweats during a pandemic). What is the sale price of each sweatshirt and each pair of sweatpants?
Answer:
Step-by-step explanation:
let
x = price of a sweatshirt
y = trice of sweatpants
three sweatshirts and two pairs of sweatpants for $85.50
3x + 2y = 85.50
three more sweatshirts and four more pairs of sweatpants for $123
3x + 4y = 123
by solving the system of equations
3x + 2y = 85.50
3x + 4y = 123
we find
x = $16
y = $18.75

A book has a font and a back and 400 pages. The front and back cover are each 0.9mm thick, measured to 1 decimal place. Each page is 0.13mm thick measured to 2 decimal places calculate the minimum thickness of the book
Answer:
53.8 mm
Step-by-step explanation:
Front page and a back page + 400 pages.
The front and back cover are each 0.9mm thick, measured to 1 decimal place.
Total thickness of front and back page = 0.9mm × 2
= 1.8 mm
Each page is 0.13mm thick measured to 2 decimal places
Total number of pages = 400
Total thickness of the pages = Thickness of each page × Total number of pages
= 0.13mm × 400
= 52 mm
minimum thickness of the book = Total thickness of front and back page + Total thickness of the pages
= 1.8mm + 52mm
= 53.8 mm
The minimum thickness of the book is 53.8 mm

The price of Nintendo Switch was reduced from $300 to $240 during a
Black
Friday sale. By what percentage was the price of the gaming system
reduced?
Answer:
20% or .2
Step-by-step explanation:
First divide 240 by 300
240/300
this gives you .8, you would then subtract that from 1 to get .2
You can check your answer by multiplying 300 by .2
300*.2
this gives you 60 which is the difference between the 2 numbers

y = -5x
When x = -2 ; y = -5* (-2) = 10 ; (-2 , 10)
When x = -1 ; y = -5 *(-1) = 5 ; (-1 , 5)
When x = 0 , y = 0 ; (0 , 0)
When x = 1 ; y = -5 *1 = -5 ; (1 , -5)
When x = 2 ; y = -5 *2 = -10 ; (2 , -10)

the unit digit in the square of 18 is 21 how many natural numbers lie between 12 square and 13 square
Answer:25
Step-by-step explanation:
Reena bought a jacket for £45 . six months later ,she sold it for £34.65.What was her percentage loss?
When Reena bought a jacket for $45 and after six months later she sold it for $34.65, then the percentage loss is 25%
Given,
Reena bought a jacket for = $45
Selling price of jacket = $34.65
Here, selling price is lower than cost price, so we can consider it as loss
We know,
Loss percentage = (Loss / Initial cost)×100
Loss = Initial cost - Selling price
Loss = 45 -34.65= $10.35
Loss percentage =[tex](\frac{10.35}{45}) 100[/tex]
=0.25×100
=25%
Hence, when Reena bought a jacket for $45 and after six months later she sold it for $34.65, then the percentage loss is 25%

Answer:
The answer is "6"
Step-by-step explanation:
[tex]\to x^2 = 3 \times 12 \\\\\to \sqrt{6^2 +3^2} = \sqrt{45} =\sqrt{9} \sqrt{5} = 3\sqrt{5} \\\\\to x= 6[/tex]

Solve the system of equations.
7x−3y=20
y=5x−4
x=
y=
Answer:
Step-by-step explanation:
substitute the value of y in the first equation.
7x-3(5x-4)=20
7x-15x+12=20
-8x=20-12
x=8/-8
x= -1
then you substitute the value of x on the y equation to find y
y=5×-1 -4
y= -5-4
y= -9
Answer:
x = -1, and y = -9
Step-by-step explanation:
This is done by solving one of the two equations for x or y, then substituting it in place of that variable in the other equation.
Since y is already clearly defined in the second equation let's go with that:
[tex]Given\ 7x - 3y = 20,\ and\ y = 5x - 4[/tex]
[tex]7x - 3(5x - 4) = 20[/tex]
[tex]7x - 15x + 12 = 20[/tex]
[tex]7x - 15x = 20 - 12[/tex]
[tex]-8x = 8[/tex]
[tex]x = -1[/tex]
Now we can replace x in the equation for y with -1:
[tex]y = 5(-1) - 4[/tex]
[tex]y = -5 - 4[/tex]
[tex]y = -9[/tex]
To make sure our answers are correct, let's substitute them into the original equations:
[tex](-9) = 5(-1) - 4\\-9 = -5 - 4\\-9 = -9[/tex]
Good, let's test the other equation
[tex]7(-1) - 3(-9) = 20\\-7 - (-27) = 20\\-7 + 27 = 20\\20 = 20[/tex]
So we know that our answer is correct.
