Answer:
He pays to the cab driver for 25 miles.
Step-by-step explanation:
Consider the provided information.
Let us consider he walks x miles at the rate of 4 miles per hour.
As we know 
Therefore, time taken is: 
He get a taxi for (31-x) miles at the rate of 50 miles per hour.
Therefore, time taken is: 
It took 2 hours after he started.
That means the sum of time take is 2 hours.
Hence he walk 6 miles and he get a taxi for 31-6=25 miles.
He pays to the cab driver for 25 miles.
I agree with Marita, that the angles could have the same measure. This can be proven if you set the two amounts equal and solve for x.
9x - 25 + x = x + 50 + 2x - 12
To begin, we should combine like terms on both sides of the equation to start simplifying the equation.
10x - 25 = 3x + 38
Next, we should subtract 3x from both sides and add 25 to both sides to get the variable x alone on the left side of the equation.
7x = 63
Finally, we should divide both sides by 7, to get rid of the coefficient of x.
x = 9
If you plug in 9 for x in our first equation, you get that both of the angle measurements equal 65 degrees. This means that Marita is correct, because if x = 9, then the angles would have the same measure.
Answer:
First, remember that a circle of radius R centered in the point (a, b) can be written as:
(x - a)^2 + (y - b)^2 = R^2
Suppose that we can model the yard as a rectangular coordinate axis.
And the tree is planted in the point (a, b)
If we want to have 15 feet in all directions around the base of the tree (15 ft around the point (a, b))
The section that must remain unplanted is:
(x - a)^2 + (y - b)^2 ≤ R^2
Where the ≤ symbol is used because all the interior of the circle must remain unplanted (border included)
When 10 meters of something is divided into 6 equal parts,
then each part is (1,666 and 2/3) millimeters long.
A). Whole number . . . No, that's not a whole number
B). Interger . . . No, there's no such thing as an 'interger'.
C). Rational number . . . Yes, its the ratio of 10,000 to 6 .
D). Irrational number . . . No, it's not irrational.
