The airplane must travel [tex]\sqrt{315}[/tex] km to be directly above the airport.
What is Pythagoras Theorem?Pythagoras theorem states that for a right angled triangle, the square of the hypotenuse is the sum of the squares of base and altitude.
We have to apply the Pythagoras theorem to solve the problem.
By Pythagoras theorem,
Base² + Altitude² = Hypotenuse²
Given,
Altitude = 3 km
Hypotenuse is the slant distance from the airport = 18 km
Let x be the distance plane must travel to be directly above the airport.
x² + 3² = 18²
x² = 315
x = [tex]\sqrt{315}[/tex]
Hence the distance plane must travel is [tex]\sqrt{315}[/tex] km.

pedro placed an order with an online nursery for 6 apple trees and 5 azaleas and the order came to $219. the next order for 3 apple tree and 4 azaleas came to $132. what was the unit cost for each apple tree and for each azalea?
The cost for each apple tree is; $24 and fit each azalea would be; $15.
What is a system of equations?
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Let consider X = apples trees and Y= azaleas
Therefore, the system of equation is;
6x + 5y = 219
3x + 4y = 132
Solving;
-2(3x + 4y = 132)
-6x - 8y = -264
6x + 5y = 219
-3y = -45
-3y/-3 = -45/-3
y = 15
Now substitute;
6x + 5y = 219
6x + 5(15) = 219
6x + 75 - 75 = 219 - 75
6x/6 = 144/6
X = 24
Thus, The cost for each apple tree is; $24 and fit each azalea would be; $15.

Lines N and Pare parallel. Angle M measures 126 degrees. Find the measure of angle Q.
Answer:
Q= 126°
Step-by-step explanation:
Using the picture given, because these are parallel lines broken by a transversal, we can say the following
M=A=Q=F
B=C=D=G
Since, for example, M and C are the same line, we can say that M+C=180 and so on.
M=Q
Q= 126°

holding the torch?
Answer: 33.9 inches
Step-by-step explanation:
Assuming you meant to write that the length of the right arm holding the torch is 1 inch:
The statue is 305 feet tall and the replica is 9 inches tall.
If the replica's right arm is 1 inch, the actual arm will be:
= 1 * 305/9
= 33.9 inches
If right arm of replica was not 1 inch, use this answer as reference.

ty-qy+p=r solve for y
Answer:
[tex]\huge\boxed{y= \frac{r-p}{t-q}}[/tex]
Step-by-step explanation:
In order to solve for y in this equation, we can algebraically manipulate it to isolate y one one side of the equation.
Step 1: Subtract [tex]p[/tex] from both sides of the equation.
[tex]ty - qy + p - p = r[/tex] [tex]ty-qy=r - p[/tex]Step 2: Factor out the common term [tex]y[/tex] from the left side
[tex]y( t-q ) = r-p[/tex]Step 3: Divide both sides by [tex]t-q[/tex]
[tex]\frac{y(t-q)}{t-q} = \frac{r-p}{t-q}[/tex] [tex]y = \frac{r-p}{ t-q}[/tex]Hope this helped!

Given KW is perpendicular to JO, JP is perpendicular to KO, KN intersects with JP=Q. Prove that triangle OKW ~ triangle OJP
Answer:
Proved
Step-by-step explanation:
m∠JPO = 90 = m∠OWK, and angle O is common between both triangles [reflexive property]. Therefore by Rule AA, ΔOKW~ΔOJP
Triangle OKW similar to triangle OJP by angle-angle or AA or ΔOKW ~ ΔOJP by AA.
What is the similarity law for triangles?It is defined as the law to prove that the two triangles have the same shape, but it is not compulsory to have the same size. The ratio of the corresponding sides is in the same proportions and the corresponding angles are congruent.
Please refer to the attached picture for the diagram.
We have:
KW is perpendicular to JO, JP is perpendicular to KO.
KN intersects with JP=Q.
From the figure:
Angle JPO =Angle OWK = 90 degrees
By using the reflexive property:
Angle O = Angle O
Thus, triangle OKW similar to triangle OJP by angle-angle or AA or ΔOKW ~ ΔOJP by AA.

kiersten is 6ft tall. She is standing in front of a tree and notices her shadow. If her shadow is 9 feet away from her and the shadow of the tree is 84 feet away from the tree, how tall is the tree?
If kiersten is 6ft tall. She is standing in front of a tree and notices her shadow and her shadow is 9 feet away from her. The height of the tree is 56 feet.
How to find the height?Given data:
kiersten height = 6ft tall
Shadow = 9 feet away
Shadow of tree = 84 feet
The equation that will be use to find the height is 6/9= x/84
Let x represent the tree's height
So, let solve for x
6/9= x/84
Cross multiply:
9x = 6(84)
9x = 504
Divide both side by 9x
x= 504/9
x = 56 feet
Therefore we can conclude that the height of the tree is 56 feet.

Answer: 2 weeks
Step-by-step explanation:
The office had already recycled 13 kilograms of paper this year and need to recycle a total of 29.
The number of kilograms left is:
= 29 - 13
= 16 kilograms of paper
Recycling at a rate of 8kg per week, the number of weeks it will take them to reach 16 kilograms is:
= 16 / 8
= 2 weeks
