Explanation:
14/5 represents situation where we have 14 objects and we need to divide it in 5 equal parts. Therefore, these situations are
A. Renee has 14 feet of ribbon that she will cut into 5 pieces of equal lenght
F. Arianna pours 5 equal servings of lemonade from a bottle containing 14 ounces
For the first case, 14/5 will be the length of the pieces and for the second case 14.5 represents the amount of ounces in each serving.

Define a variable, using let statements, set up an equation, then solve. Mark flew from Boston to Baltimore, then Baltimore to Orlando. the number of people on his first flight was five more than four times the number of people on his second flight. if there were 365 people altogether on the two flights how many were on the flight from Baltimore to Orlando?
Answers
First flight = f
second flight = s
Equations
f + s = 365 Equation 1
f = 4s + 5 Equation 2
Solve by substitution
(4s + 5) + s = 365
4s + 5 + s = 365
5s = 365 - 5
5s = 360
s = 360 / 5
s = 72
Find f
f = 4(72) + 5
f = 288 + 5
f = 293
Result
In the flight from Baltimore to Orlando there were 72 people.

Find the equation of the line passing through the points (10,8) and (-10,30). Write your answer in the form
Answers
The equation of a line in slope-intercept form is given by:
[tex]y=mx+b[/tex]Where m is the slope and b is the y-intercept.
We know two points on the line: (10,8) and (-10,30).
The slope can be found by using the following formula:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]Where (x1,y1) and (x2,y2) are the coordinates of two points on the line. By replacing the known coordinates we obtain:
[tex]m=\frac{30-8}{-10-10}=\frac{22}{-20}=-\frac{11}{10}[/tex]The y-intercept can be found by replacing the slope and one of the points in the slope-intercept formula, and solving for b:
[tex]\begin{gathered} 8=-\frac{11}{10}\cdot10+b \\ 8=-11+b \\ 8+11=b \\ b=19 \end{gathered}[/tex]Thus, the equation of the line is:

Answers
The surface area of the Japanese Lanterns Tamera made when the sides are 9 inches long will be 522 sq inches.
What is surface area?The Surace area of any 2D or 3D figure is the outer area of the given figure.
Surface areas are of two types they are lateral surface area when we exclude the areas of top and bottom and total surface area is when we include all the sides.
Given that Tamera is using rice paper to make Japanese Lanterns.
The expression 2s² + 40s represents the surface area of a lantern where the base edges are 's' inches long.
Therefore to find The surface area of the Japanese Lanterns when the sides are 9 inches in length we have to substitute 9 into the variable s.
So, 2(9)² + 40(9).
= 2×81 + 360.
= 162 + 360.

Miles per gallon of a vehicle is a random variable with a uniform distribution from 23 to 47. The probability that a random vehicle gets between 28 and 36 miles per gallon is?
Answers
The probability that a random vehicle gets between 28 and 36 miles per gallon is 0.3333.
What's probability?Probability is an area of mathematics that deals with numerical descriptions of how probable an event is to occur or how likely a statement is to be true. The probability of an event is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty.
Given that,
a = 23
b = 47
P(c < x < d) = (d - c) / (b - a)
P(28 < x < 36) = (36 - 28) / (47 - 23) = 0.3333

What is speed- distance formula?Speed, time, and distance relationships
Distance/Time x Speed This reveals how quickly or slowly an object is moving. It gives the amount of time it took to travel a certain distance divided by the distance travelled.Speed is inversely correlated with time and directly correlated with distance. Therefore, as the speed increases, the time required, because Time = Distance / Speed. Distance = Speed X Time.Each Speed, Distance and Time can be expressed in different units:
Time: seconds(s), minutes (min), hours (hr)Distance: (meters (m), kilometers (km), miles, feetSpeed: m/s, km/hrGiven:
distance= 5.2 m
speed= 4 m/ min

Regarding the points on the given line, it is found that:
a) The midpoint is: (3,4.5).
b) The coordinates of C are: C(4,5).
c) The coordinates of the other end of the line are: (4,3).
MidpointThe midpoint between two points is given by the mean of the coordinates of these points.
In this problem, the coordinates of points A and B are given as follows:
A(0,3) and B(6,6).
Hence the coordinates of the midpoint are given as follows:
x-coordinate: (0 + 6)/2 = 3.y-coordinate: (3 + 6)/2 = 4.5.As for point C, we have that C is closer to B then A, hence:
The x-coordinate is greater than 3.The y-coordinate is greater than 4.5.The coordinates are integers, hence it is given as follows:
C(4,5).
As for line AB, it is found that:
The other line is parallel, hence the slope is also of 0.5. (change in y divided by change in x is of 0.5).For the x-coordinate, on line AB, they change by 6, hence in the new line they increase by 2/3 x 6 = 4.For the y-coordinate, on line AB, they change by 3, hence in the new line they increase by 2/3 x 3 = 3.Thus the other endpoint is:
(4,3).

The solutions to the absolute value equations are given as follows:
1. k = -8 or k = 8.
2. x = -7 or x = 7.
3. a = -10 or a = 6.
4. a = -2.5 or a = 2.5.
5. m = -4 or m = 22.
6. x = -4 or x = 6.8.
7. x = -16 or x = 9.
8. a = -2.4 or a = 1.2.
What is the absolute value function?The absolute value function is defined by the following piecewise rule, depending on the input of the function:
|x| = x, x ≥ 0.|x| = -x, x < 0.This means that there are two possible solutions for the equation |x| = a, which are:
x = a or x = -a.
Item 1The equation is:
|k| = 8.
Applying the definition of the absolute value function, we have that the possible solutions are:
k = -8 or k = 8.
Item 2The equation is:
|x| = 7.
Applying the definition of the absolute value function, we have that the possible solutions are:
x = -7 or x = 7.
Item 3The equation is:
|a + 2| = 8.
The possible solutions are that the inside term can be equals to either -8 or 8, hence:
a + 2 = -8 -> a = -10.a + 2 = 8 -> a = 6.Item 4The equation is:
|8a|/10 = 2
In standard format, the equation is:
|8a| = 20
Then the solutions are:
8a = -20 -> a = -20/8 = -2.5.8a = 20 -> a = 20/8 = 2.5.Item 5The possible solutions are:
-m + 9 = -13 -> m = 22.-m + 9 = 13 -> m = -4.Item 6The possible solutions are:
7 - 5x = -27 -> 5x = 34 -> x = 6.8.7 - 5x = 27 -> 5x = -20 -> x = -4.Item 7Applying cross multiplication, the expression is:
|2x + 7| = 25
The possible solutions are:
2x + 7 = -25 -> 2x = -32 -> x = -16.2x + 7 = 25 -> 2x = 18 -> x = 9.Item 8Applying cross multiplication, the expression is:
|-3 -5a| = 9.
The possible solutions are:
-3 - 5a = -9 -> 5a = 6 -> a = 1.2.-3 - 5a = 9 -> 5a = -12 -> a = -2.4.More can be learned about absolute value equations at https://brainly.com/question/5012769

Answers
Answer:
t = 23
Explanation:
If the dollar amount d varies directly as the number of hours, t, the equation that relates these variables is
d = kt
Where k is a constant.
We know that for d = $116.25, t = 15 h, so we can replace these values and solve for k as follows
116.25 = k(15)
116.25/15 = k(15)/15
7.75 = k
Then, the equation that relates d and t is
d = 7.75t
Now, we know that d = $178.25 and we want to calculate t, so replacing d and solving for t, we get
178.25 = 7.75t
178.25/7.75 = 7.75t/7.75
23 = t
Therefore t = 23
