The distance of each flight is 60 miles and the time taken is 40 minutes.
Distance is the total path covered by an object or species in a particular time period.
At x = 0 minutes after takeoff,
f(x)=60−1.5x (given)
= 60-1.5*0 (at 0 minutes)
= 60 miles (distance between the helicopter and destination)
So, the distance of the flight is 60 miles.
When the helicopter reaches the destination, distance left is 0 miles
Thus, f(x) = 0 in x minutes.
Putting the above data in the equation, we get
0 = 60 - 1.5x
1.5x = 60 (bringing unlike terms on different sides)
x = 60/1.5
x = 40 minutes
Therefore, the distance of each flight is 60 miles and the time taken is 40 minutes.

Find each of the numbers below.
Simplify your answers as much as possible.
The opposite of 0:
The opposite of 7:0
The opposite of the opposite of 6:
The opposite of 0 is 0, the opposite of 7 is -7 and the opposite of 6 is -6.
If we consider a number x, then the opposite of the number x will be equal to -x. In a number line the opposite of a number lying on the positive side always lies on the negative side of number line. Also, the opposite of a number -x is the x that is the number itself. It is given in the question that we need to find opposite of 0, 7 and 6.
Let x = 0, opposite of x is -x.
=> -x = -0
=> -x = 0
Now, let x = 7, opposite of x is -x
=> -x = -7
Now, let x = 6, opposite of x is -x
=>-x = -6
Thus, the opposite of the numbers 0, 7 and 6 are 0, -7 and -6 respectively.

What is linear equations?
Linear equations are a subset of first order equations. One homogeneous variable of degree one constitutes a linear equation in one variable (i.e., only one variable). A linear equation could contain multiple variables. When a linear equation comprises two variables, for instance, linear equations in two variables are utilized. A mathematical statement known as an equation contains an algebraic expression and the equal symbol (=). It is the equation for a straight line. The equation is shown to be valid when values are substituted for the unknown values in the solutions of linear equations. When there is just one variable, there is just one answer.
How to Solve?
Solving a linear equation involves determining the answer to a linear equation with one, two, three, or more variables. The answer to a linear equation is the value or values of the variable(s) that are part of the equation. There are six main ways to resolve linear equations. For the purpose of solving linear equations, these methods include the Graphical Method, Elimination Method, Substitution Method, Cross Multiplication Method, Matrix Method, and Determinants Method.
Let the greater of the two numbers be "x" and the smaller one be "y".
Given, x - y = 1200 --(i) & x + y = 6484 --(ii)
Adding (i) and (ii), we get, 2x = 7684 ⇒ x = 3842
Subtracting (i) from (ii), we get, 2y = 5284 ⇒ y = 2642
Thus, the greater number of the two numbers is 3842 and the smaller number is 2641.

Dixon and his little sister Ariadne stand next to each other on the playground on a sunny afternoon. Their mother measures their shadows. Ariadne's shadow is feet long and Dixon's shadow is feet long. If Ariadne is feet tall, how tall is Dixon?
Using the similar triangle principle, the height of Dixon in feet is 6 feet.
How to find the side of similar triangle?Ariadne's shadow is 15 feet long and Dixon's shadow is 18 feet long.
Ariadne is 5 feet tall.
The height of Dixon can be found using similar triangle principle.
Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles.
Therefore, using the similar triangle theory,
Let
x = height of Dixon
Hence,
shadow length of Ariadne / Ariadne height = Dixon shadow length / Dixon height
shadow length of Ariadne = 15 ft
Ariadne height = 5 feet
Dixon shadow length = 18 feet
15 / 5 = 18 / x
cross multiply
15 × x = 18 × 5
15x = 90
divide both sides by 15
15x / 15 = 90 / 15
x = 6 ft
Therefore, Dixon height is 6 feet.

Jacob ran 10 miles in 80 minutes at that rate how far would he run in 21/2 hours? (*hint - 1 hour = 60 minutes)
If Jacob ran 10 miles in 80 minutes at that he will run the distance of 18.75 miles in [tex]2\frac{1}{2}[/tex] hours
Number of miles that Jacob will run in 80 minutes = 10 miles
Number of miles that Jacob will run in 1 minutes = Number of miles that Jacob will run in 80 minutes/ 80

= 0.125 miles
We know,
1 hour = 60 minutes
[tex]2\frac{1}{2}[/tex] hours = 2.5×60

Number of of miles that Jacob will run in 150 minutes = Number of miles that Jacob will run in 1 minutes × 150

The probability of getting an even number greater than 800 is 0.08
Total outcomes possible when a three-digit number is formed without repetition:
Using the digits 3,4,5,6,7 and 8:
The first digit can be filled in using any of the 6 options
The second digit can be filled using the remaining 5 options
The third digit can be filled in using the remaining 4 options
So, total outcomes possible = 6*5*4 = 120 possibilities
Now, finding even number greater than 800:
The first digit can only be filled by 8 for a number to be greater than 800 which means there is only one option for the first digit
The second digit can be filled using any of the remaining options except 8 which means there are 5 options
The last digit can be filled using 4 and 6 because these are the only even numbers which mean 2 options
Total possible outcomes = 1*5*2 = 10 possibilities
