A four seat Cessna airplane does an average of 5.84 miles per gallon of fuel traveling from Olympia to Hoquiam
Given that a four seat Cessna airplane uses an average of 11 gallons of avgas per hour, and it traveled from Olympia to Hoquiam for 28minutes, then we can solve for the amount of fuel it consumed for that flight.
amount of fuel = average consumption x time
amount of fuel = 11 gallons of avgas per hour x 28 minutes
amount of fuel = 11 gallons of avgas per hour x (28/60)h
amount of fuel = 77/15 gallons
If the flight from Olympia to Hoquiam is 30 miles and the amount of fuel used by the Cessna airplane is 77/15 gallons, then
average number of miles per gallon of fuel = distance traveled / amount of fuel consumed
average number of miles per gallon of fuel = 30 miles / (77/15 gallons)
average number of miles per gallon of fuel = 450/77
average number of miles per gallon of fuel = 5.84 miles / gallon of fuel

Find the coordinates of point P on →AB that partitions the segment into the given ratio AP to PB .
b. A(0,0), B(-15,0), 2 to 3
The line segment AB is divided at point P, which has coordinates P(0,-7.5)
A line segment is a section of a line that connects two locations to create a straight line or we can say that is connects two distinct points together to form a single line. It is extendable to either side.
Given are,
A line segment AB with coordinates of A(0,0 ) and B(-15,0) respectively
Two minor line segments, AP and PB, are created from the line segment AB by the provided point P
We must determine the dividing point's coordinates, or P.
We'll apply the formula provided,
The coordinates of the point P are given by = ([tex]\frac{x1+x2}{2}[/tex],[tex]\frac{y1+y2}{2}[/tex] )
Now, x1 = 0, x2 = 0, y1 = -15, y2 = 0
Putting values in the formula, we get
([tex]\frac{0+0}{2}[/tex], [tex]\frac{0-15}{2}[/tex])
(0,-7.5)
Hence, the point P which partitions the line segment AB have coordinates as P(0,-7.5)

Answer:
3x+1
Step-by-step explanation:
Determine whether the given measures define 0,1,2 , or infinitely many triangles. Justify your answers.
a=25, b=21, m
We can form an endless number of triangles when you are given two sides and no measurement of angle i.e a = 25 , b = 21
For Example -
We can chose the value of angle from 0-360 degrees with side length a = 25 and b =21, how many different triangles are possible to create?
Create one of the triangles with a protractor having the side lengths a = 25 m and b = 21 m and angle 12° and third side can be adjusted to your preferred length. You have built a triangle.
Similarly by changing the length of the third side and measure of the angle we will get an entirely new triangle.
It's important to notice that you choose the side lengths and angle. This suggests that you might make a different decision. By employing the same angles, you were able to make an infinite number of different triangles.
Therefore, with simply the measurements of one angle and a side length, we can create an endless number of triangles.

A circle is a curve sketched out by a point moving in a plane. The radius and the circumference of the circle are 13 inches and 81.6814 inches, respectively.
What is a circle?A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the center.
Given that diameter of the circle is 26 inches. Therefore, the radius and the circumference of the circle can be written as,
Diameter of circle = 2 × (Radius of the circle)
Radius of the circle= Diameter of circle / 2
Radius of the circle = 26 inches / 2
Radius of the circle = 13 inches
Circumference of circle = 2 × π × (Radius of the circle)
= 2 × π × 13 inches
= 26π inches
= 81.6814 inches

whats the formula for speed distance and time?
We know the formulae:
[tex]\text{Speed} = \dfrac{\text{Distance}}{\text{Time}}[/tex]
Let us solve an example to understand the concept better.
Example:Question: Find the speed of a car which travelled 12 km in 2 hours.
Solution: We know the following
Car travelled (Distance): 12 kmTime travelled: 2 hoursSubstitute the information provided into the speed formula:
[tex]\implies \text{Speed} = \dfrac{\text{Distance}}{\text{Time}}[/tex]
[tex]\implies \text{Speed} = \dfrac{\text{12 km}}{\text{2 hours}} = \boxed{6 \ \text{km/hour}}[/tex]
Therefore, the speed of the car is 6 kilometers per hour.
Concept #2: Distance FormulaeFrom the previous concept, we had:
[tex]\text{Speed} = \dfrac{\text{Distance}}{\text{Time}}[/tex]
Finding the distance formula through step-by step work:
Let Speed = S, Distance = D, and Time = T.
[tex]\implies \text{S} = \dfrac{\text{D}}{\text{T}}[/tex]
Multiply "t" on both sides:
[tex]\implies \text{S} \times \text{T}= \dfrac{\text{D}}{\text{T}} \times \text{T}[/tex]
[tex]\implies \text{S} \times \text{T}={\text{D}[/tex]
From the above work, we can say that Distance = Speed × Time.
Let us solve an example to understand the concept better.
Example:Question: A train travelled from point A at a speed of 16 km/h in 2 hours to reach point B. Find the distance (Point A - Point B) travelled by the train.
Solution: We know the following
Speed of train: 16 km/hTime taken to travel from A to B: 2 hoursSubstitute the information provided into the distance formula:
[tex]\implies \text{Distance = Speed} \times \text{Time}[/tex]
[tex]\implies \text{Distance = 16 km/h} \times \text{2 hours}[/tex]
⇒ Distance = 16 km × 2 = 32 km
Therefore, the train travelled 32 km to reach point B.
Concept #3: Time FormulaeFrom the previous concept, we had:
[tex]\text{Distance = Speed} \times \text{Time}[/tex]
Finding the time formula through step-by step work:
Let distance = D, speed = S, and time = T
[tex]\implies \text{D = S} \times \text{T}[/tex]
Dividing "S" both sides:
[tex]\implies \dfrac{\text{D}}{\text{S}} = \dfrac{\text{S} \times \text{T}}{\text{S}}[/tex]
[tex]\implies \dfrac{\text{D}}{\text{S}} = \text{T}[/tex]
From the above work, we can say that Distance/Speed = Time.
Let us solve an example to understand the concept better.
Example:Question: A plane traveled 200 km at a speed of 100 km/h. How much time did it take to travel 200 km?
Solution: We know the following
Distance travelled by the plane: 200 kmSpeed of plane: 100 km/hSubstitute the information provided into the time formula:
[tex]\implies \text{Time} = \dfrac{\text{Distance}}{\text{Speed}}[/tex]
[tex]\implies \text{Time} = \dfrac{\text{200 km}}{\text{100 km/h}} = \dfrac{\text{2 km}}{\text{1 km/h}} = \boxed{\text{2 hours}}[/tex]
Therefore, it took 2 hours to travel 200 km at a speed of 100 km/h.
