The most appropriate choice for speed will be given by-
Average speed of Trevon is 56 mph
What is speed?
The distance travelled by the body per unit time is called speed of the body.
If d is the distance travelled by the body and t is the time taken, then
speed = [tex]\frac{d}{t}[/tex]
Speed is a scalar quantity as the direction is not taken into account.
Here,
Let the average speed of Trevon be [tex]x[/tex] mph
Average speed of Mike = [tex](x + 14)[/tex] mph
Time for which Trevon driven = [tex](4 + 1)[/tex] h
= [tex]5[/tex] h
Time for which Mike driven = [tex]4[/tex] h
By the problem,
[tex]5 \times x = 4 \times (x+14)[/tex]
[tex]5x = 4x+56[/tex]
[tex]5x-4x=56[/tex]
[tex]x =56[/tex] mph

The points (-3, r) and (4, -24) lie on a line with slope -4. Find the missing coordinate r=
If the points (-3, r) and (4, -24) lie on a line with slope -4 then the missing coordinate r = 4.
What is coordinate?
A coordinate in mathematics is any magnitude that is used to define the location of a point, line, or something similar in relation to a fixed figure, system of lines, etc.
Given in the question,
The slope of the line is -4,
The coordinate points on the line are (-3, r) and (4, -23).
The formula to calculate the slope of a line is:
[tex]m = \frac{y_2-y_1} {x_2 - x_1}[/tex]
Here, m = slope, and (x1, y1) ,(x2, y2) are the points on the line
On putting the values given in question in this formula, we get
[tex]-4 = \frac{-24-r} {4 - (-3)}[/tex]
[tex](-4)7 = -24-r[/tex]
[tex]28-24 = r = 4[/tex]
r = 4
Hence, the value of missing coordinate r is 4

The points (6, -2) and (h, -3) fall on a line with a slope of 1/3. What is the value of h?
======================================================
Work Shown:
m = 1/3 is the given slope
We'll use the slope formula to solve for h.
[tex](x_1,y_1) = (6,-2) \text{ and } (x_2,y_2) = (h,-3)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\\frac{1}{3} = \frac{-3 - (-2)}{h - 6}\\\\\frac{1}{3} = \frac{-3 + 2}{h - 6}\\\\\frac{1}{3} = \frac{-1}{h-6}\\\\1(h-6) = 3(-1)\\\\h-6 = -3\\\\h = -3+6\\\\h = 3[/tex]
-----------------------------
Let's check the answer.
The point (h,-3) updates to (3,-3)
The claim is that the points (6,-2) and (3,-3) fall on a line with slope 1/3.
Use the slope formula to get the following:
[tex](x_1,y_1) = (6,-2) \text{ and } (x_2,y_2) = (3,-3)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{-3 - (-2)}{3 - 6}\\\\m = \frac{-3 + 2}{3 - 6}\\\\m = \frac{-1}{-3}\\\\m = \frac{1}{3}\\\\[/tex]
We get a slope of 1/3 as expected.
The answer is confirmed.
A slope of 1/3 means that each time you move up 1 unit (rise), move to the right 3 units (run).
Answer:
17/3
Explanation:
Make it into a fraction like
6-h/-2+3 = 1/3
this equals 6-h/1=1/3
18-3h=1

What is an example of cultural diffusion that was found in Faiyum?
In the Fayum Basin during the first and third century BCE, Egyptians established a practice of painting pictures of their loved ones on wood or linen panels, which would eventually be glued to their mummified remains.
For centuries, scholars have been fascinated by these Fayum mummy portraits. Humans have attempted to identify their departed family members since the dawn of time.
Egyptians were no exception to this rule. Nonetheless, because of the numerous nations that conquered. The pictures were definitely impacted by the influence of different cultures, and they influenced Egypt.
Each leadership wave carried with it new ambitions and influences. With the exception of the Assyrians, who were infamous for their violent reign, and the Persians, each victorious country before the Amon priests aspired to reestablish a Pharaoh, probably to establish the role of a god-king (Kamil, "Coptic Egypt," 16-18). Despite the ruler changes, there remained a quite stable set of Egyptian ideas and customs.

What would be the total cost of purchasing the number of shirts needed to use your
coupon—after your coupon is applied and a 7.5% sales tax is charged on the purchase?
Please write a original answer
The total cost of purchasing the number of shirts needed to use your coupon is $40.32.
What is the cost?Discount = 25%
Total price before coupon = $50
Sales tax = 7.5%
Therefore, the calculation based on the information will be:
= Total price - Discount + (Discount × Tax)
= $50 - (50 × 0.25) + (37.5 × 7.5%)
= 50 - 12.5 - 2.82
= $40.32

B. The cost of a pizza plus a 2$ tip divided by 10 people
C. The cost per pizza for 10 pizzas divided by 2 people
D. The cost per pizza for 2 pizzas divided by 10 people
Step-by-step explanation:
it is not clear what you mean by 2x ? 10.
I assume you mean 2x / 10 (divided).
in any case, D is the only answer that makes sense with a "2x" term.
x would then stand for the price of a single pizza.
2x is then the price for 2 pizzas.
2x / 10 is then the share of the costs of the 2 pizzas per person, if there are 10 people sharing (the costs are evenly split among 10 parties).

It takes 53 years until we run out of gas.
Given,
Reserves of natural gas = 6500 TCF
Consumption per year = 123 TCF
Therefore,
years left ( x )= Reserves of natural gas / Consumption per year
= 6500/123
= 52.8 years

Determine whether each function is an example of exponential growth or decay. Then, find the y-intercept. y=0.5(1/4)^x
Because the base is 1/4, which is smaller than 1, we conclude that this is an exponential decay.
Is the function an exponential growth or decay?
A general exponential function is of the form:
y = A*(b)^x
Where A is the initial value, b is the base, and x is the variable.
If 0 < b < 1, then we have an exponential decay.
if b > 1, then we have an exponential growth.
In this case, the function is:
y = 0.5*(1/4)^x
So b =1/4 < 1.

Using the properties of permutation and combination we can calculate that there are possible 3 ,4 ,5 ,6 or 8 people in the group.
A permutation of a set is, broadly speaking, a rearranging of its elements if the set is already ordered, or arranging its members into a sequence or linear order.
The act or procedure of altering the linear order of an ordered set is referred to as a "permutation."A combination is a choice of items from a group of different items where the order of the choices is irrelevant.There are 2 to 10 people in the group.
Lets us consider there are 3 people. Ticket price = 240 / 3= $80
Lets us consider there are 4 people. Ticket price = 240 / 4= $60
Lets us consider there are 5 people. Ticket price = 240 / 5= $48
Lets us consider there are 6 people. Ticket price = 240 / 6= $40
Lets us consider there are 8 people. Ticket price = 240 / 3= $30
Hence from the properties of permutation and combination we can see that there could be 3 ,4,5,6 or 8 people.
