Signs are placed at regular intervals along a mountain road to indicate altitude. At Grinbrir Lodge, the sign indicates an elevation of 876 meters. But 17 kilometers down the road, another sign indicates that the elevation is 672 meters. What is the average elevation change per kilometer traveled from the Lodge
Answer:
-12 m/km
Step-by-step explanation:
You want to know the average elevation change per kilometer given the elevation changes from 876 meters to 672 meters over a distance of 17 kilometers.
Rate of changeThe average elevation change per kilometer is found by dividing the elevation change by the number of kilometers. The elevation change is the difference between the ending elevation and the starting elevation.
rate of change = ((end elevation) -(start elevation))/(distance)
= (672 m -876 m)/(17 km) = (-204 m)/(17 km) = -12 m/km
The average elevation change is -12 meters per kilometer traveled from the lodge.

How many points of intersection are there between the graphs of the two hyperbolas?
The graphs of the hyperbola have zero point of intersection.
What is the point of intersection?The point of intersection is the point where two or more functions meet.
The given parameters;
3x² – 4y² + 4x – 8y +4= 0
3x² + y² + 4x – 3y +4= 0
To find the points of intersection, we simply equate both equations.
So;
3x² – 4y² + 4x – 8y +4= 3x² + y² + 4x – 3y +4
Now Cancel out the common terms
y² - 3y = - 4y² - 8y
Collect like terms;
y² + 4y²= 3y - 8y
5y² = - 5y
Divide through by 5
y² = -y
Divide through by y
y = -1
Hence, the graphs of the hyperbola have zero point of intersection.

if once taxi fare was $7.65 how many miles did he travel in the taxi a taxi company charges $2.25 for the first mile and then $0.20 per mile for additional mile or f equals $2.25 + $0.20(m -1) where f is the fair and m is Adam's number of miles
Answer:
28 miles
Explanation:
The equation that describes the relationship between the fare and the number of miles is:
f = 2.25 + 0.20(m - 1)
Where f is the fare and m is the number of miles.
So, if the taxi fare was $7.65, we can replace f by 7.65. Then:
7.65 = 2.25 + 0.20(m - 1)
Therefore, we can calculate the number of miles by solving the equation for m. So, subtracting 2.25 from both sides:
7.65 - 2.25 = 2.25 + 0.20(m - 1) - 2.25
5.4 = 0.20(m - 1)
Dividing by 0.20, we get:
[tex]\begin{gathered} \frac{5.4}{0.20}=\frac{0.20(m-1)}{0.20} \\ 27=m-1 \end{gathered}[/tex]Finally, add 1 to both sides:
27 + 1 = m - 1 + 1
28 = m
So, he travels 28 miles in the taxi

The area of a trapezium is calculated with the following formula:
[tex] \frac{a + b}{2} \times h[/tex]
(a: base, b: base, h: height)
[tex] \frac{ 7 + (10.4)}{2} \times (6.7) \\ \\ \frac{17.4}{2} \times (6.7)[/tex]
get rid of fraction by dividing (17.4) with 2
(17.4)÷2 = 8.7 multiply this with height
(8.7) × (6.7) = 58.29
The area of the given trapezium is 58.29 cm².
What is a trapezium?In American and Canadian English, a quadrilateral with at least one pair of parallel sides is referred to as a trapezoid. A trapezium is a term used for a trapezoid in British and other varieties of English. These two terms were transposed due to a typo in Charles Hutton's mathematical dictionary.So, the area of the trapezium:
Formula: (a+b)/2 × hWhere, a = 7, b = 10.4 and h = 6.7.Solve as follows:
(a+b)/2 × h(7 + 10.4)/2 × 6.717.4/2 × 6.78.7 × 6.758.29 cm²Therefore, the area of the given trapezium is 58.29 cm².

Step-by-step explanation:
To find the perimeter, you must add the lengths of all sides.
In this question the perimeter is given, which is 63.
63 = 12 + 12 + 3x + 2x + 1 + x + 2
1. Add the numbers
63 = 12 + 12 + 3x + 2x + 1 + x + 2
12 + 12 + 1 + 2 = 27
63 = 27 + 3x + 2x + x
2. Combine Like Terms
63 = 27 + 3x + 2x + x
x = 1
3x + 2x + 1x = 6x
63 = 27 + 6x
3. Move Variable to the left
63 = 27 + 6x
63 = 6x + 27
4. Subtract 27 from both sides, the opposite of adding 27
63 = 6x + 27
63 - 27 = 6x + 27 - 27
36 = 6x
5. Divide by the same factor, the opposite of multiplying 6
36 = 6x
36/6 = 6x/6
6. Cancel out the 6s but leave the x
36/6 = 6x/6
x = 6
So, now that we know that x = 6 we can solve the expression, x + 2, to find out the length of the side BC.
6 + 2 = 8
(a)A circle has a radius of 12cm. If the radius is increased by a factor of 7, how's many times larger will the circle's circumference be? (b)What is the scale factor of the circumference of a circle with a radius of 3 when compared to the original circle? Write your answer as a decimal to the nearest hundredth.
The circumference of a circle is found using the formula,
[tex]C=2\pi r[/tex]Where
C is the circumference
r is the radius
A circle has radius 12 cm, so its circumference is
[tex]\begin{gathered} C_1=2\pi r \\ C_1=2\pi(12) \\ C_1=24\pi \end{gathered}[/tex]When the radius (12 cm) is increased by a factor of 7, we mean the radius is 7 times the original, so, the new radius is
[tex]7\times12=84[/tex]So, the circumference of this circle will be >>>>
[tex]\begin{gathered} C_2=2\pi r \\ C_2=2\pi(84) \\ C_2=168\pi \end{gathered}[/tex]To find how many times larger this circumference is of the previous one, we divide,
[tex]\frac{C_2}{C_1}=\frac{168\pi}{24\pi}=7_{}[/tex]Answer7(b)Using the circumference formula, we can find the circumference of this circle,
[tex]\begin{gathered} C=2\pi r \\ C=2\pi(3) \\ C=6\pi \end{gathered}[/tex]The original circle had a circumference of 24π
The question basically asks "how many times is the circumference of this circle compared to the circumference of the original circle?"
Of couse, it will be less than 1 since this circle is smaller than the original one.
So,
[tex]\begin{gathered} \frac{6\pi}{24\pi} \\ =\frac{1}{4} \end{gathered}[/tex]So, the scale factor is 1/4, or 0.25

A car travels for 15km in a city at a Certain speed-Dutside the city it travels 72km at twice its former speed. If the total travelling time is 1hour 8minutes find the average speed .
If the total traveling time is 1 hour 8 minutes f the average speed is 45 km/h.
This is a problem from time and distance. We can solve this equation by following a few steps.
Let's assume the car travel in the city for t minutes and the average speed is v.
According to the question, the car travel outside the city for, (68- t) minutes as 1 hour 8 minutes is equal to 68 minutes.
Therefore, the average speed (v) in the city = 15/t km/minute as v = s/t where v represents the speed, t represents the taken time and s represents the distance.Hence, the speed outside the city = 72/(68- t) km/minute.As per the question, Outside the city, it travels at twice its former speed v.
Now, we can form an equation, 2 (15/t) = 72/(68- t).
Let's simplify the given equation. 30/t = 72/(68- t)
Or, 72t = 30(68- t) [cross multiplication]
Or, 72t = 2040 - 30t
Or, 102t = 2040 [add with +30t both sides]
Or, t = 2040/102
Or, t = 20 [dividing by 102 both sides]
Therefore we can conclude that the average speed ( km/h) is (15×60) / 20 = 45 km/h.

for which values of (A) the system has at least one solution
Answer
The values of a that ensures that the system has at least one solution is
a > (21/127)
Explanation
We are told to find the values of a that ensures that the system has at least one solution. The system of equations include
3 (a - 5x) < 1 + x
2 - (x/2) > 3 + 5 (x - a)
To do this, we need to solve the expressions
3 (a - 5x) < 1 + x
3a - 15x < 1 + x
We can rewrite this as
1 + x > 3a - 15x
x + 15x > 3a - 1
16x > 3a - 1
Divide both sides 16
[tex]\begin{gathered} \frac{16x}{16}>\frac{3a-1}{16} \\ x>\frac{3a}{16}-\frac{1}{16} \end{gathered}[/tex]We then solve the second one. But to do this, let's multiply through by 2
2 - (x/2) > 3 + 5 (x - a)
4 - x > 6 + 10 (x - a)
we can rewrite as
6 + 10 (x - a) < 4 - x
6 + 10x - 10a < 4 - x
10x + x < 10a - 6 + 4
11x < 10a - 2
Divide both sides by 11
[tex]\begin{gathered} \frac{11x}{11}<\frac{10a-2}{11} \\ x<\frac{10a}{11}-\frac{2}{11} \end{gathered}[/tex]The two solutions are
x > (3a/16) - (1/16)
x < (10a/11) - (2/11)
To find a lasting solution, we need the inequality sign to be the same, so, we need to multiply through one of the equations by -1
x > (3a/16) - (1/16)
-x < (-3a/16) + (1/16)
So, the system of equations become
-x < (-3a/16) + (1/16)
x < (10a/11) - (2/11)
We can then add the two equations
-x + x < (-3a/16) + (1/16) + (10a/11) - (2/11)
0 < (-3a/16) + (10a/11) + (1/16) - (2/11)
0 < -0.1875a + 0.9091a + 0.0625 - 0.1818
0 < 0.7216a - 0.1193
Rewrite
