A large nest of recently hatched bald eagles is located at the top of the Eiffel Tower (which is 324 meters tall) and is attracting much attention from the many visitors to the city of Paris. A tourist is standing at ground level, 54 meters across from the Eiffel Square, aiming her binoculars at the nest. At what angle should she set her binoculars in order to see the next? Round your answer to the nearest tenth of a degree.
9514 1404 393
Answer:
80.5°
Step-by-step explanation:
The applicable trig function is the tangent.
Tan = Opposite/Adjacent
In this scenario, the side opposite the angle is the tower height, 324 m. The side adjacent is the distance to the tower, 54 m. Then the angle α is related by ...
tan(α) = 324/54
The value of the angle with this tangent is found using the arctangent function:
α = arctan(324/54) ≈ 80.5°
She should set her binoculars to 80.5°.
Al, Tom and Joe share €3000.
The ratio of the amount Al gets to the amount Tom gets is in the
ratio 5:4
Joe gets 1.5 times the amount Tom gets.
Work out the amount of money that Tom gets.
Answer:
Tom's share = €800
Step-by-step explanation:
Given that:
Amount shared by Al, Tom and Joe = €3000
Ratio of Al's share to Tom's share = 5 : 4
Joe's share = 1.5(Tom's share) = 1.5(4) = 6
Therefore,
Ratio of Al, Tom and Joe = 5 : 4 : 6
Let,
x be the number of times of amount each get.
5x + 4x + 6x = 3000
15x = 3000
Dividing both sides by 15
[tex]\frac{15x}{15}=\frac{3000}{15}\\x=200[/tex]
Tom's share = 4x = 4(200) = €800
Hence,
Tom's share = €800
Meyer used 8 loads of gravel to cover 2/5 of his driveway. How many loads of gravel will he need to cover his entire driveway?
Answer:Meyer uses 2.5 loads
Step-by-step explanation:Why does he use 2.5? Because, he has 8 loads and with 1 load he covers 2/5 of his driveway so 2 loads covers 4/5 and 2.5 loads cover 5/5 of his driveway

Which of the following is the product of the rational expressions shown below?
Answer:
(3x^2+6x)/(x^2-16)
Step-by-step explanation:
When multiplying fractions you just go straight accross
this means that our fraction is equal to
((x+2)(3x))/((x-4)(x+4))
The numerator is quite easy 3x(x+2)=3x^2+6x
The second one is a little tough at first and if you need help I would reccomend using khan academy
but pretty much you get x^2-16
put them together and get your answer

Millie expected 20 friends to show up to her birthday party, but 24 attended. What was
her percent error? Round to the nearest percent.
Answer:
Her percent error was: ≈ 17% (whole percent)
Step-by-step explanation:
Given
Approximate value = 20 friends
Exact Value = 24 friends
To determine
Percent error
Using the formula to calculate the Percent error
Percent error = | Approximate Value| - Exact Value | / | Exact value | × 100
= | 20 - 24 | / | 24 | × 100
= | - 4 | / | 24 | × 100
Apply absolute value: |-a| = a, a>0
= 4/24 × 100
= 16.67 %
≈ 17% (whole percent)
Thus, her percent error was: ≈ 17% (whole percent)

Answer:
True!
Step-by-step explanation:
If an object travels at a constant speed, then the distance traveled is directly proportional to the time spent traveling, with the speed being the constant of proportionality. The circumference of a circle is directly proportional to its diameter, with the constant of proportionality equal to π.

1/2x + 3 = x + 5 what is the first step?
Answer:
The first thing to do when solving an algebraic equation is the isolate the variable. Thus, simply subtract 1/2x from both sides of the equation and subtract 5 from both sides to get [tex]-2=\frac{1}{2} x[/tex]
Someone plz help me this is urgent!
Answer:
5^12
Step-by-step explanation:
When you have a power to the power, you multiply the powers. Since we have (5^3)^4, we can multiply the powers because we have a power to the power. Since 3 * 4 is equal to 12, we have 5^12. That means that 5^12 is the answer.

Given the circumference of a circle is 8π centimeters, calculate the area of the circle in terms of π.
Answer:
16π cm²
Step-by-step explanation:
circumference = 2πr
Area = πr²
We need to determine r to calculate the area
2πr = 8π
Divide both sides of the equation by 2π to find r
r = 4
Now, we determine area.
area = πr² = π4² = 16πcm²
Answer:
[tex]\Large\boxed{\sf{16\pi\text{cm}^2}}[/tex]Step-by-step explanation:
The formula for the circumference of a circle can be used to solve this problem.
[tex]\underline{\text{CIRCLE OF A CIRCUMFERENCE FORMULA:}}[/tex]
[tex]:\Longrightarrow: \sf{C=2\pi r}[/tex]
[tex]\text{AREA:}= \sf{\pi r^2}[/tex]
[tex]\sf{2\pi r=8 \pi}[/tex]
You have to divide by 2 from both sides.
[tex]\sf{\dfrac{2\pi r }{2}=\dfrac{8\pi}{2} }[/tex]
Solve.
Divde the numbers from left to right.
8/2=4
r=4
[tex]\sf{\pi r^2=\pi4^2}[/tex]
Solve by exponents.
[tex]\sf{4^2=4*4=\boxed{\sf{16}}[/tex]
[tex]\Longrightarrow: \boxed{\sf{16\pi \text{cm}^2}}[/tex]
Therefore, the correct answer is 16πcm².I hope this helps. Let me know if you have any questions.
