The table shows the distance traveled by 4 cycleists. Sort the speeds of the riders, in miles per hour, from slowest to fastest.
Answers
The speed from slowest to the fastest is Julio; Elana; Kevin; Lorena.
Given that a table shows the distance traveled by 4 cyclists as shown in attached images.
Speed is defined as . The rate at which an object changes position in any direction. Speed is measured as the ratio between distance and time traveled.
Firstly, we will calculate the speed of Elena.
The given distance is 20(1/2) mi or it can be written as 41/2mi and the time is 2(1/4) hr or 9/4hr.
Now, substitute the values in speed formula that is
Speed=Distance/Time
Speed=(41/2)/(9/4)
Speed=(41/2)×(4/9)
Speed=82/9 mi/hr.
Now, we will calculate its speed of Julio.
The given distance is 12(1/4) mi or it can be written as 49/4mi and the time is 1(1/2) hr or 3/2hr.
Now, substitute the values in speed formula that is
Speed=Distance/Time
Speed=(49/4)/(3/2)
Speed=(49/4)×(2/3)
Speed=49/6 mi/hr.
Further, we will calculate the speed of Kevin.
The given distance is 20(2/3) mi or it can be written as 62/3mi and the time is 1(2/3) hr or 5/3hr.
Now, substitute the values in speed formula that is
Speed=Distance/Time
Speed=(62/3)/(5/3)
Speed=(62/3)×(3/5)
Speed=62/5 mi/hr.
Furthermore, we will calculate the speed of Lorena.
The given distance is 33(1/4) mi or it can be written as 133/4mi and the time is 2(1/3) hr or 7/3hr.
Now, substitute the values in speed formula that is
Speed=Distance/Time
Speed=(133/4)/(7/3)
Speed=(133/4)×(3/7)
Speed=57/4 mi/hr.
Hence, the speeds from slowest to fastest from the given table is Julio; Elana; Kevin; Lorena.

Fiona has a coupon for $3 off the price of her meal at a local fast food establishment. her favorite meal is on sale at a special rate of 10% off the combo price. if fiona paid $8.25 for her meal, before taxes, what was the original price of the meal?
Answers
The Original price of the meal was $12.16.
Discount Percent is defined as the discount given on the product per hundred .
For Example . if there is 10% discount on a price of $100.
The final amount will be $90.
Final amount paid by Fiona = $8.25
percentage discount = 10%
Let the original amount be x.
According to the question ;
x - 10% of x = 8.25
[tex]x-\frac{10}{100} *x=8.25\\ \\ \frac{100x-10x}{100} =8.25\\ \\ \frac{90x}{100} =8.25\\ \\ x=\frac{8.25*100}{90}\\ \\ x=\frac{825}{90} \\ \\ x=9.16[/tex]
Since Fiona also had a discount coupon of $3.
The original amount will be $9.16+$3=$12.16.
Therefore , The original price of the meal was $12.16.

Equation: 2x + x + 72 = 180m∠1 = 72°m∠2 = 108°Step-by-step explanation:
The angles lie on a straight line summing to total 180 degrees.
Form an equation:
m∠1 + m∠2 = 180
2x + x + 72 = 180
and solve:
3x + 72 = 180
3x = 180 - 72
3x = 108
x = 36
Find m∠1: 2(x) = 2(36) = 72°Find m∠2: x + 72 = 36 + 72 = 108°Answer:
see below
Step-by-step explanation:
We are here given a straight line which is splitted into two parts by a line , such that it makes two angles.
Also we know that the angle measure of a straight line is 180° . Therefore; here the sum of angles 1 and 2 will be 180° .
So that,
==> angle 1 + angle 2 = 180°
==> 2x + x + 72° = 180°
==> 3x = 180° - 72°
==> 3x = 108°
==> x = 108°/3
==> x = 36° .
The equation which we used to solve the problem is ,
==> Equation = 2x + x + 72° = 180°
For finding the individual angels substitute the value of x into their expressions , as ;
==> angle 1 = 2x = 2(36°) = 72°
==> angle 3 = x + 72° = 36° + 72° = 108° .
And we are done!

the equation of a line in slope- intercept form is
y = mx + c ( m is the slope (gradient) and c is the y- intercept )
given
x - 2y = 8 ( subtract x from both sides )
- 2y = - x + 8 ( divide through by - 2 )

The constant ______ of _______ between points on a line.
Answers
The slope, rise over run, or change in over the change in of a line determines its rate of change. A graph's slope triangle or two points in a table can be used to compute the slope.
How far is it between the two locations?
By calculating the sum of the absolute values of the y-coordinates, you may determine the distance between two places in different quadrants with the same x-coordinates.
What does a line's slope indicate?
A line's steepness can be determined by looking at its slope. Slope is calculated mathematically as "rise over run" (change in y divided by change in x).
Describe slope using an example?
The slope-intercept form of an equation is used whenever the equation of a line is expressed in the form y = mx + b. M represents the line's slope. B is the b in the location where the y-intercept is located (0, b). For instance, the slope and y-intercept of the equation y = 3x - 7 are 3 and 0, respectively.Learn more about slope

(5x − 11)
(3x + 11)
find y
Please help, I’m not sure what I’m doing.
Answers
Step-by-step explanation:
Fact 1: Alternate angles are equal.
Angles, (5x-11)° and (3x+17)° are ALTERNATE angles and so,
(5x-11)° = (3x+17)°
5x - 3x = 17 + 11
2x = 28
x = 28 ÷ 2
x = 14
NB: x does NOT have the degree sign because it's NOT an angle on its own, but rather within the bracket/part of the calculation to get the angle degree.
Fact 2: Opposite angles are equal.
Y° and (3x+17)° are OPPOSITE angles
y = (3x+17)°
y = (3x14) + 17
y= 42 + 17
y = 59°
Hope this helps!

Which exponential function bests models the graph below?

Answers
Option A. [tex]Y = 3(2)^{X}[/tex]
Here, looking at the graph we can see that when x = 0, the value of y will be 3. Thus, (0, 3) is a solution to the given function.
Putting x = 0 in the given options, we see that
A. y = 3(1) = 3 (as anything raised to the power is 1)
B. y = 2(1) = 2
C. y = 4(1) = 4
D. y = 3(1) = 3
Thus, we can eliminate option B and C as (0, 3) does not satisfy these equations.
Now, if we take x = 1, from the graph we can see that the value of y will be 6.
Substituting x = 1 in the remaining two options, we get
A. y = 3(2) = 6
D. y = 3(4) = 12
Thus, D is also eliminated.
Option A, y = 3(2)^x is the correct answer.
