An airplane is flying at a height of 200m. Its angle of elevation to an observer on the ground is 230. Calculate the distance of the airplane from the observer.
Answer:
Distance between the plane and the observer is 511.86 miles.
Step-by-step explanation:
From the figure attached,
A plane is flying at point A which is at 200 m height and observer is at point C.
Angle of elevation (∠ACB) of the plane from the observer is 23°.
Let the distance between the observer and the plane is x meters.
By applying sine ratio for angle C,
sin(∠C) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
sin(23°) = [tex]\frac{200}{x}[/tex]
x = [tex]\frac{200}{\text{sin}(23)}[/tex]
x = 511.86 miles
Therefore, distance between the plane and the observer is 511.86 miles.
At a bake stall there is a large square pan of chocolate brownies. Customers can buy any fraction of the pan of brownies they like.The first customer bought 1/2 of the pan of brownies. The second customer bought 5/6 of what was left of the pan of brownies. What fraction of the whole pan did the second customer buy
Answer: 5/12
Step-by-step explanation:
Since the first customer bought 1/2 of the pan of brownies. This means that the pan of brownies left will be:
= 1 - 1/2
= 1/2
The The second customer bought 5/6 of what was left of the pan of brownies, the fraction that the second customer bought will be:
= 5/6 × 1/2
= 5/12
Answer:
5/12
Step-by-step explanation:
At a bake stall there is a large square pan of chocolate brownies. Customers can buy any fraction of the pan of brownies they like.
The first customer bought 1/2 of the pan of brownies.
The amount of brownies that was left over is given as:
1 - 1/2 = 1/2 brownies left ove
The second customer bought 5/6 of what was left of the pan of brownies.
The amount of brownies the second customers bought is calculated as:
5/6 of 1/2
= 5/6 × 1/2
= 5/12
What fraction of the whole pan did the second customer buy

how do you know you have a direct variation in the relationship between two quantities?
Answer:
Say you have y=2x. That is direct variation and will always pass through the origin when graphed. When x is multiplied by a number, the y value will also be changed by that number. If you add a y-intercept and change y=2x to, for example, y=2x+2, the x and the y will no longer be related by a constant ratio.

A principal of $3100 is invested at 3% interest, compounded annually. How many years will it take to accumulate $4000 or more in the account? (Use the
calculator provided if necessary.)
Write the smallest possible whole number answer.
Answer:
8.46 years
Step-by-step explanation:
Given data
P=$3100
R= 3%
A= $4000
Calculate time, solve for t
t = ln(A/P) / r
substitute
t=ln(4000/3100)/3
t=ln1.290/0.03
t= 0.254/0.03
t= 8.46
Hence the time is 8.46 years

(4a^3+5a^2-a+1)-(5a-2a^3+3)
Answer:
6a^3 + 5a^2 - 6a - 2
Step-by-step explanation:
(4a^3 + 5a^2 - a + 1) - (5a - 2a^3 + 3)
Combine like terms
4a^3 - (-2a^3) = 6a^3 (- times - = +)
-a - 5a = -6a
1 - 3 = -2
Now combine the answers in standard form (don't forget the 5a^2)

Considerate of these three numbers express and scientific notation 8.2×10 to the -3rd power 5.2×10 to the $96 and 4.1 times since I'm -6 hours which number is the greatest invite how many times does it rather than smallest number
Answer:
[tex]8.2 * 10^{-3}[/tex] is the greatest
2000 times greater
Step-by-step explanation:
Given
[tex]8.2 * 10^{-3}[/tex]
[tex]5.2 * 10^{-6}[/tex]
[tex]4.1 * 10^{-6}[/tex]
Solving (a): The greatest of the numbers
First, we convert them to decimals:
[tex]8.2 * 10^{-3} = 0.0082[/tex]
[tex]5.2 * 10^{-6} = 0.0000052[/tex]
[tex]4.1 * 10^{-6} = 0.0000041[/tex]
By comparing the decimal numbers, the highest is: 0.0082.
Hence,
[tex]8.2 * 10^{-3}[/tex] is the greatest
Solving (b): How many times greater than the smallest
In (a) above:
The greatest is: [tex]8.2 * 10^{-3}[/tex]
By comparing the decimal numbers,
The smallest is: 0.0000041 i.e. [tex]4.1 * 10^{-6}[/tex]
The number of times the greatest is greater than the smallest is:
[tex]Number = \frac{8.2 * 10^{-3}}{4.1 * 10^{-6}}[/tex]
[tex]Number = \frac{0.0082}{0.0000041}[/tex]
[tex]Number = 2000[/tex]
Hence, it is 2000 times greater

Step-by-step explanation:

Need answer ASAP I’m timed What is the distance between the points (7, 8) and (-8, 0) on a coordinate grid?
Answer:
17
Step-by-step explanation:
(7, 8) (-8, 0)
First find how much the point moved in y to the second point.
8-0=8
So one side is 8.
Then find how much it moved in x. 7-(-8)=15
So the other side is 15
This will give you 2 sides of a triangle where one sides lenght is 8 the other is 15. Use the pythagoras theorem which is x squared plus y squared = c squared
8^2+15^2=c^2
64+225=c^2
289=c^2 Take the square root of both sides to solve for C
√289= √C^2
17 = c
Ashley and Gabby bought lunch from the food trucks on Sugar Day. Ashley bought 3 tacos and a drink for $7. Gabby bought 2 drinks and 2 tacos for $8. How much does 1 taco cost? A taco costs__
Answer:
$1.5
Step-by-step explanation:
This would be solved using a simultaneous equation
let tacos = t
drink = d
3t + d = 7 -- eqn 1
2t + 2d = 8 -- eqn 2
Multiply equation 1 by 2 to derive equation 3
6t + 2d = 14 eqn 3
Substract equation 2 from equation 3
6t + 2d = 14 -- eqn 3
-
2t + 2d = 8 -- eqn 2
= 4t = 6
solve for t
6/4 = 1.5
= $1.5

HURRY PLEASE find the lcm of 2x-6 and 4x+12 and x^2-9
Answer: 4 ( x − 3 ) ( x + 3 )
Step-by-step explanation:
The least common multiple (LCM) of two or more non-zero whole numbers is the smallest whole number that is divisible by each of those numbers. In other words, the LCM is the smallest number that all of the numbers divide into evenly.
Answer:
Below.
Step-by-step explanation:
2x - 6 = 2(x - 3)
4x + 12 = 4(x + 3)
x^2 - 9 = (x - 3)(x + 3)
So the LCM is:
4(x - 3)(x + 3)
or 4x^2 - 36.

write 16+32 as a product of two factors using the GCF and the distributive property.
Answer:
48
Step-by-step explanation:
16+32=16(1+2)=16(3)=48
16 + 32 as product of two factors = 16 × 3
What is factor?A factor is a number that divides another number completely with no remainder. Factors and multiples are related concepts in math.
Given expression,
16 + 32
It can be written as
4 × 4 + 4×4×2
Greatest common factor = 4×4 = 16
16(1) + 16(2)
Using Distributive property, factoring out the GCF
16 (1 + 2)
16 × 3
Hence, 16 × 3 is the product form of 16 + 32.

This triangle has one side that lies on an extended line segment. Based on this triangle, what statement about x is true? A. x = 27 because 180−109−44=27 B. x = 65 because 109−44=65 and 44 + 65 = 109 C. x = 71 because 180−109=71 D. x = 153 because 109 + 44 = 153 and 153−44=109
MEASUREMENTS (down below)
A triangle with base on an extended line. Two angle measures are given. Top interior angle is forty-four degrees. Lower right exterior angle is one hundred nine degrees. Lower left interior angle is labeled x degrees.
Answer:
B. x = 65 because 109−44=65 and 44 + 65 = 109
Step-by-step explanation:
Given :
The triangle below :
Sum of interior angles of a triangle :
(44° + x + (180 - 109) = 180°
44° + x + 71° = 180
115° + x = 180°
x = 180° - 115°
