On Saturday morning , Owen earned $ 24 . By the end of the afternoon he had earned a total of $ 60 . Enter an equation , using x as your variable , to determine whether Owen earned $ 36 or $ 31 on Saturday afternoon .
Owen earned $ 36 on Saturday afternoon
Solution:
Let "x" be the amount earned by Owen between morning and afternoon
On Saturday morning , Owen earned $ 24
By the end of the afternoon he had earned a total of $ 60
From given information,
Amount earned on saturday morning + Amount earned on saturday afternoon = Total money earned
Therefore,
24 + x = 60
x = 60 - 24
x = 36
Hence Owen earned $ 36 on Saturday afternoon

The formula for the perimeter of a rectangle is p=2(l+w). If the width of a rectangle is half its length, how many times its length is its perimeter??
Answer:
2
Step-by-step explanation:
if you take half of something then you divide my 2
Final answer:
The perimeter of a rectangle whose width is half its length is three times the length of the rectangle. This can be calculated using the formula p = 2(l + w), substituting w with l/2, which simplifies to p = 3l.
Explanation:
The student is asking how many times a rectangle's length is its own perimeter if the width of the rectangle is half its length. Using the formula for the perimeter of a rectangle, which is p = 2(l + w), and knowing that the width (w) is half the length (l), we can substitute w with l/2.
Hence, the formula becomes p = 2(l + l/2) = 2(3l/2) = 3l. Therefore, the perimeter is three times the length of the rectangle.

George is twice as old as Edward, and Edward’s age exceeds Robert’s age by 4 years. If the sum of the three ages is at least 56 years, what is Robert’s minimum age?
To find Robert's minimum age, we need to determine the ages of George and Edward first. Let's assume Edward's age is x. According to the information given, George is twice as old as Edward, so George's age is 2x. Edward's age exceeds Robert's age by 4 years, meaning Robert's age is x - 4. The sum of the three ages is at least 56 years, so we can write the equation x + 2x + (x - 4) >= 56.
Explanation:To find Robert's minimum age, we need to determine the ages of George and Edward first.
Let's assume Edward's age is x. According to the information given, George is twice as old as Edward, so George's age is 2x.
Edward's age exceeds Robert's age by 4 years, meaning Robert's age is x - 4.
The sum of the three ages is at least 56 years, so we can write the equation x + 2x + (x - 4) >= 56. Simplifying this, we get 4x - 4 >= 56. Adding 4 to both sides, we have 4x >= 60. Dividing by 4, we find that x >= 15.
Therefore, Edward's minimum age is 15 years, and Robert's minimum age is 15 - 4 = 11 years.
The vertices of about isosceles trapezoid are located at (2,5),(6,5),(9,3) and?
To determine the fourth vertex of an isosceles trapezoid given three vertices, we use symmetry and properties of isosceles trapezoids, concluding the missing vertex is likely at (-1,3).
Explanation:To find the fourth vertex of an isosceles trapezoid given three vertices, we need to use the properties of isosceles trapezoids. The properties pertinent to solving this problem include parallel bases and non-parallel sides of equal length. Given vertices at (2,5), (6,5), and (9,3), we know the top base is parallel to the x-axis, as the y-coordinate is the same (5) for the first two points.
For the trapezoid to be isosceles, the fourth vertex must follow the pattern of equal non-parallel sides. Observing the pattern of the given points, and noting that the length of the non-parallel side from (9,3) should equal that of the side starting from (2,5), we conclude the missing point must maintain this equality in distance and form a right angle, mirroring the shape on the opposite side.
Without specific lengths, we apply symmetry principles. The height difference between the known base and the third vertex (3) indicates a 2-unit drop, suggesting the opposite side will mirror this. Thus, the fourth vertex should be 2 units below the other base vertex, at (2,5), making the y-coordinate 3. Given the distances in x are equal (4 units from each end vertex to their respective base vertex), the fourth vertex is at (-1,3).

Find a average daily rainfall for a 30 days month if the total rainfall during that period was 16.8 inches.
Average = 0.56 inches
Solution:
Given data: Total rainfall = 16.8 inches
Total number of days for a month = 30
To find the average of the rainfall.
Formula for average:
[tex]\text {Average}=\frac{\text {Sum of the observations}}{\text {Total number of observations}}[/tex]
[tex]\text {Average}=\frac{16.8}{30}[/tex]
= 0.56 inches
Average = 0.56 inches
Hence, average of daily rainfall is 0.56 inches.
what is the approximate perimeter of the triangle below? Angle A is 50, Angle B is 60 and line CA is 90 in
Answer:
267.3 in.
Step-by-step explanation:
Using the Sine Rule:
90 / sin 60 = BC/ sin 50
BC = 90 sin 50 / sin 60 = 79.6 in.
Angle C = 180 - 50 - 60 = 70 degrees.
90 / sin 60 = AB / sin 70
AB = 90 sin 70 / sin 60 = 97.7 in.
So the perimeter = 90+ 79.6 + 97.7
= 267.3 in.

Plz hel I’ve got a test 2morrow ant if I don’t figure this out I’m fricked
I need 13 through 16
I'll do the first two problems (13 and 14) to get you started.
===========================================================
Problem 13
I'm going to use square blocks instead of marbles. The same idea applies either way. I'm using blocks because they are easier to draw out.
Draw 9 square blocks that are connected end-to-end forming a long chain. Write O in the first four blocks to represent "orange". Write G in the remaining 5 blocks to represent "green". See figure 1 in the attached image below.
This diagram represents the fact that the orange and green blocks form a ratio of 4:5. There are 4 parts that are orange and 5 parts that are green.
If we have 6 rows of these blocks (see figure 2), then we'll have 6*5 = 30 green blocks overall. This leads to 6*4 = 24 orange blocks. So far we have 30+24 = 54 blocks that are green or orange.
-----
Let x be the total number of blocks
40% of the total x is the number of yellow
40% of x = 0.40*x
60% of x is the remaining number
0.60*x = 54
x = 54/0.60
x = 90
There are 90 blocks total
40% of 90 = 0.40*90 = 36 are yellow
60% of 90 = 0.60*90 = 54 are either green or orange
-----------------
Final Answer: 36 yellow marbles===========================================================
Problem 14
Michael has 40 books. Susan has 50% more books than Michael. This means she has 1.5 times as many books
1.5*40 = 60
Susan has 60 books
If Michael buys 8 more books, then he will have 40+8 = 48, which is still less than 60. Susan still has more books.
-------
Let's compute the percentage difference
A = 48 is the amount of books Michael has
B = 60 is the amount Susan has
C = percent difference
C = 100*(B-A)/A
C = 100*(60-48)/48
C = 25%
Susan has 25% more books compared to Michael
-----------------
Final Answer: Susan will still have more books. She will have 25% more books after Michael buys those 8 books.What document changed the purpose of the Civil War from one of states' rights to that of slavery?
the Thirteenth Amendment
Declaration of Independence
the Fugitive Slave Law
Emancipation Proclamation
Answer:
The Emancipation Proclamation is the document that changed the purpose of the Civil war from one of states' rights to that of slavery.
Step-by-step explanation:
The Emancipation Proclamation is the document that changed the purpose of the Civil war from one of states' rights to that of slavery.
The main idea behind this document was to clearly state that " all persons held as slaves" in the southern states "are, and henceforward shall be free."
When the north won the civil the above mentioned words in quotes of the Emancipation Proclamation document effectively guaranteed the freedom of all people held as slaves in all of United States of America.

Option C:
[tex]y+6=\frac{3}{5} (x-4)[/tex]
Solution:
Given point (4, –6) and slope, [tex]m=\frac{3}{5}[/tex]
Formula for equation of a straight line when passing through the point [tex](x_1, y_1)[/tex] and slope m is [tex]y-y_1=m(x-x_1)[/tex]
Here, [tex]x_1=4, y_1=-6, m=\frac{3}{5}[/tex]
Substitute these in the above formula, we get
⇒ [tex]y-(-6)=\frac{3}{5} (x-4)[/tex]
⇒ [tex]y+6=\frac{3}{5} (x-4)[/tex]
Hence, [tex]y+6=\frac{3}{5} (x-4)[/tex] is the equation in point-slope form.

Line m passes through the Point (2, 1) and has a slope of -2/7. What is the equation of Line m in standard form?
7x + 2y = 11
7x + 2y = 16
2x + 7y = 11
2x +7y = 16
Answer:
Step-by-step explanation:
Slope m = -2/7
Points are (2,1)
y1 = 1 and x1 = 2
y - y1 = m(x - x1)
y -1 = -2/7(x - 2)
Multiple each term by 7
7y - 7 = -2(x - 2)
7y - 7 = -2x + 4
7y = -2x + 4 + 7
2x + 7y = 11

amanda ran 4 laps around the school track. Clifford ran half as many laps as brian ran. Together the 3 friends ran 13 laps. How many laps did bryan run
Answer: 6 laps
Step-by-step explanation:
13 - 4= 9 left 6 and half would be three
To find out how many laps Bryan ran, an equation was formulated combining the laps Amanda and Clifford ran with the total laps, which, when solved, showed Bryan ran 6 laps.
Explanation:To solve the problem, let's denote the number of laps Bryan ran as B, Amanda ran 4 laps, and Clifford ran half as many laps as Bryan, so that's B/2 laps.
According to the problem, together they ran a total of 13 laps.
Now we can write an equation based on the information given:
4 + (B/2) + B = 13
Next, we solve for BD:
Combine like terms:
B + B/2 = 13 - 4
1.5B = 9
Divide by 1.5 to solve for B:
B = 9 / 1.5
B = 6
So, Bryan ran 6 laps.
