Greetings from Brasil...
Using set theory to solve this question
Let
D = Dogs Set
C = Cats Set
R = Classroom Set
n(D ∪ C) = n(D) + n(C) - n(D ∩ C)
n(D ∪ C) = 14 + 11 - 3
n(D ∪ C) = 22
Then,
Total = n(D ∪ C) + 24
Total = 22 + 24
Total = 465. Owen walked 5 miles in 4 hours. Fill out a table of

The ratio between Miles and Hours is 5:4
In the table, miles = 40 is got by 8 x 5 = 40
So corresponding hours = 8 x 4 = 32
In the table, hours = 36 is got by 9 x 4 = 36
So corresponding miles = 9 x 5 = 45
So the ratios are 5:4 , 40:32, 45:36
Graph can be plotted with number of miles in the x-axis and number of hours in y-axis.
The points to be plotted are (5, 4), (40,32) and (45, 36). Joint these points to get a straight line on the graph.

The hotel staff is decorating the lobby by placing one row of string lights along the outer edge of the rectangular ceiling.

What is the approximate length of string lights the staff needs to decorate the ceiling?The complete question is added as an attachment
From the attached figure, we have the following coordinates
A = (5, 16)
B = (17, 10)
C = (14, 4)
D = (2, 10)
Calculate the lengths AB and BC using the following distance formula
d = √[(x2 - x1)^2 + (y2 - y1)^2]
This gives
AB = √[(5- 17)^2 + (16- 10)^2] = 13.4
BC = √[(14- 17)^2 + (4- 10)^2] = 6.7
The approximate length of string lights the staff needs to decorate the ceiling is then calculated as
P = 2 * (AB + BC)
This gives
P = 2 * (13.4 + 6.7)
Evaluate
P = 40.2
Hence, the approximate length of string lights the staff needs to decorate the ceiling is 40.25

Use the position equation given below, where s represents the height of the object (in feet),
v0
represents the initial velocity of the object (in feet per second),
s0
represents the initial height of the object (in feet), and t represents the time (in seconds), as the model for the problem.
s = −16t2 + v0t + s0
You drop a coin from the top of a building. The building has a height of 1028 feet.
(a) Use the position equation to write a mathematical model for the height of the coin.
s = ?
(b) Find the height of the coin after 1.5 seconds.
s = ? ft
(c) How long does it take the coin to strike the ground? (Round your answer to two decimal places.)
t = ? sec
(I really can't comprehend how to due this but its due soon, please help me!)
Answers
Using the motion equation we can get:
a) s = -16*t^2 + 1028
b) 992 feet above the ground.
c) after 8 seconds, the coin will hit the ground.
How to write the height equation?
First, we know that the general height equation is:
s = -16*t^2 + v0*t + s0
In this case, the coin is dropped, so the initial velocity v0 is zero.
And the coin is dropped from a height of 1028 ft, then s0 = 1028
Replacing that in the equation we get:
s = -16*t^2 + 1028
b) The height after 1.5 seconds is what we get by evaluating the height equation in t = 1.5
s = -16*(1.5)^2 + 1028 = 992
This means that the height after 1.5 seconds is 992 ft above the ground.
c) The coin will strike the ground when s = 0, then we need to solve:
s = 0 = -16*(t)^2 + 1028
Solving that for t, w eget:
16*t^2 = 1028
t^2 = 1028/16
t = √(1028/16) = 8
This means that the coin will hit the ground after 8 seconds.

Answer:
2/19
Step-by-step explanation:
Rewrite the mixed number as an improper fraction. Frist, multiply 2x8 then add that to 3 to get 19/8. Now you have 1/4 / 19/8. Multiply by the reciprocal of the denominator. Now you have 1/4 x 8/19. 1 x 8 = 8. 4 × 19= 76. This gives you 8/76. You can simplify this by dividing the numerator and denominator by 4. This would give you 2/19.

Answers
From the given linear function, it is found that each descent by 88 meters was 11 seconds long.
What is the missing information?
The graph of the linear function is missing, and it is given at the end of the answer.
A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Given two points on the graph, the slope is given by change in y divided by change in x. For this problem, the points are given as follows:
(0, 440) and (40,0).
Hence the slope is:
m = (0 - 440)/(40 - 0) = -11.
Meaning that in each minute, he descended 8 meters. Thus the time to descend 88 meters is given by:
t = 88/8 = 11 seconds.
Each descent by 88 meters was 11 seconds long.

Bill has twice as much money as Bob. Paul has $12 more than Bill. Together they have $92. How much money does Bob have?
Answers
Answer:
$16
Step-by-step explanation:
Let x = how much money Bob has. (x)
Bob has twice as much money as Bob. (2x)
Paul has $12 more than Bill. (2x+12)
To find out how much money Bob has, we can add our expressions for each person and set them equal to 92.
x + 2x + 2x + 12 = 92
To simplify this equation, we first need to find the like terms and add them.
1x + 2x + 2x = 5x
5x + 12 = 92
Now that we have done that, we can find how much money Bob has by solving for x. First, we subtract 12 on both sides of the equation.
5x + 12 - 12 = 92 - 12
5x = 80
Then we divided by 5 on both sides of the equation.
5x/5 = 80/5
x = 16
Since x = 16, we know that Bob has 16 dollars.

Step-by-step explanation:
step 1 : exapnding 2(x+4) will give you 2x +8 , the student made an error in expanding
so it should then be 2x+8 = 6x-12
and then if you move the letters to one side and the numbers to the other you will get :

the student added a minus in 2x and 8 when it's suppose to be an addition that is the error
2(x+4)=6(x-2)

The average rate of change is a measure of how quickly on average one quantity changes in relation to another.
