A rose garden is formed by joining a rectangle and a semicircle, as shown below. The rectangle is 22ft long and 14ft wide.
Find the area of the garden. Use the value 3.14 for pie , and do not round your answer. Be sure to include the correct unit in your answer.
Answers
Step-by-step explanation:
To find the area of the rose garden, we need to find the sum of the areas of the rectangle and the semicircle.
Area of rectangle = length x width = 22 ft x 14 ft = 308 sq ft
Area of semicircle = (1/2) x pi x radius^2, where radius = diameter/2
The diameter of the semicircle is the width of the rectangle, which is 14 ft. So the radius is 7 ft.
Area of semicircle = (1/2) x 3.14 x 7^2 = 3.14 x 24.5 = 77.03 sq ft
Total area of rose garden = area of rectangle + area of semicircle
= 308 sq ft + 77.03 sq ft
= 385.03 sq ft
Therefore, the area of the rose garden is 385.03 square feet.

What is the simplified form of x minus 5 over x squared minus 3x minus 10 ⋅ x plus 2 over x squared plus x minus 12 ? (6 points)
Answers
The simplified form of the rational expression is given as follows:
[(x - 5)/(x² - 3x - 10)] x [(x + 2)/(x² + x - 12)] = 1/[(x + 4)(x - 3)]
How to simplify the rational expression?The rational expression for this problem is defined as follows:
[(x - 5)/(x² - 3x - 10)] x [(x + 2)/(x² + x - 12)].
To simplify the rational expression, first we must factor the quadratic equations at the denominator of each of the fractions, hence:
x² - 3x - 10 = (x - 5)(x + 2).x² + x - 12 = (x + 4)(x - 3).The simplification of the first quadratic function, x² - 3x - 10 = (x - 5)(x + 2), means that the numerators of each of the fractions can be simplified.
As the numerators of each of the fractions are simplified along with x² - 3x - 10, the remaining part is x² + x - 12, hence the simplified expression is given as follows:
[(x - 5)/(x² - 3x - 10)] x [(x + 2)/(x² + x - 12)] = 1/[(x + 4)(x - 3)]

What amount of excess reserves will Goldstar Bank now have as a result of this deposit?
Answers
Goldstar Bank will have $42,000 in excess reserves as a result of this deposit. These excess reserves can be used to make additional loans or investments.
When a customer makes a deposit in a bank, the bank is required to hold a certain percentage of that deposit as reserves. The reserve requirement is set by the central bank and is typically a percentage of the bank's total deposits.
In this case, the customer has deposited $50,000 into Goldstar Bank and the reserve requirement is 16 percent. This means that Goldstar Bank must hold 16 percent of the deposit as reserves and can loan out the remaining amount.
The amount of reserves that Goldstar Bank must hold is:
16% of $50,000 = 0.16 x $50,000 = $8,000
This means that Goldstar Bank can loan out:
$50,000 - $8,000 = $42,000
However, since the question asks for the number of excess reserves Goldstar Bank will have, we need to subtract the required reserves from the total reserves.
The total reserves after the deposit will be:
Required reserves = $8,000
Excess reserves = Total reserves - Required reserves = $50,000 - $8,000 = $42,000
Complete question:
Suppose that initially Goldstar Bank is completely "loaned up." A customer then deposits $50,000 into the bank. The reserve requirement is 16 percent.

Find the coordinates of the given vector with respect to the given basis β. (i) V=R2,β={(1,1),(1,−1)}, and v=(1,2). (ii) V=P2(R),β={1,1+x,1+x+x2}, and v=(x+1)2. (iii) V=span{sin(x),cos(x)},β={sin(x),cos(x)}, and v=sin(x+1).
Answers
The coordinates of v with respect to the basis β are (cos(1), sin(1)).
The coordinates of a vector with respect to a given basis can be found by expressing the vector as a linear combination of the basis vectors and finding the coefficients of the linear combination. These coefficients are the coordinates of the vector with respect to the given basis.
(i) In the first case, we have V=R2, β={(1,1),(1,−1)}, and v=(1,2). We can express v as a linear combination of the basis vectors as follows:
v = a(1,1) + b(1,-1) = (a+b, a-b)
Equating the coordinates, we get:
a+b = 1
a-b = 2
Solving for a and b, we get a=3/2 and b=-1/2. Therefore, the coordinates of v with respect to the basis β are (3/2, -1/2).
(ii) In the second case, we have V=P2(R), β={1,1+x,1+x+x2}, and v=(x+1)2. We can express v as a linear combination of the basis vectors as follows:
v = a(1) + b(1+x) + c(1+x+x2) = a + (b+c)x + cx2
Equating the coefficients, we get:
a = 1
b+c = 2
c = 1
Solving for a, b, and c, we get a=1, b=1, and c=1. Therefore, the coordinates of v with respect to the basis β are (1, 1, 1).
(iii) In the third case, we have V=span{sin(x),cos(x)}, β={sin(x),cos(x)}, and v=sin(x+1). Using the trigonometric identity sin(x+1) = sin(x)cos(1) + cos(x)sin(1), we can express v as a linear combination of the basis vectors as follows:
v = a(sin(x)) + b(cos(x)) = (a)sin(x) + (b)cos(x)
Equating the coefficients, we get:
a = cos(1)
b = sin(1)
Therefore, the coordinates of v with respect to the basis β are (cos(1), sin(1)).

a.Name the quantities that change in this problem situation and the quantities that
remain constant. Determine which quantity is independent and which quantity
is dependent.
B. Create a table of values to represent the total cost if Ben orders 1 or 2 books or
spends $41, $65, or $125.
Answers
Answer:
A. The quantities that change in this problem situation are the number of books Ben orders and the total cost. The quantities that remain constant are the cost per book ($12) and the shipping and handling charge per order ($5).
The independent variable is the number of books Ben orders, as this is the variable that Ben has control over and chooses to change. The dependent variable is the total cost, as it depends on the number of books Ben orders.
B.
(imagine this as a chart)
Number of books Total cost
1 $17
2 $29
3 $41
5 $65
10 $125
----------------------------------------------------------------------------------------------------------
To create this table, we used the formula:
Total cost = (Cost per book x Number of books) + Shipping and handling charge
For example, when Ben orders 3 books, the total cost is:
Total cost = ($12 x 3) + $5 = $41
Similarly, when Ben spends $65, the number of books he can order is:
Number of books = (Total cost - Shipping and handling charge) / Cost per book
Number of books = ($65 - $5) / $12 = 5
And so on for the other values in the table.
Answer:
See below
Step-by-step explanation:
Let x be he cost per book and y be the total cost including shipping and handling.
The relevant equation is
y = 12x + 5
A. Variables are number of books ordered(x) and total cost(y)
The constant is the shipping and handling cost
Since the total cost depends on the number of books ordered, the independent variable x = number of books
The total cost y is the dependent variable
--------------------------------------------------------------------------------------
B. Cost of 1 or 2 books can be found by plugging in x = 1 and x =2 into the equations and solving for y
Total Cost of 1 book = 12(1) + 5 = $17
Total cost of 2 books = 12(2) + 5 = 24 + 5 = $29
To compute the number of books that can be ordered for different total cost amounts is obtained by substituting for y and solving for x
For $41:
41 = 12x + 5
41 - 5 = 12x
36 = 12z
x = 36/12 = 3 books
For $65:
65 = 12x + 5
65 - 5 = 12x
60 = 12x
x = 60/12 = 5 books
For $125:
125 = 12x + 5
125 - 5 = 12x
120 = 12x
x = 120/12 = 10 books
Here is the table
Number Total Cost(y)

Answers
65x + 17y = -108 is the result of completing the multiplication 7x+3y=-8 4x-y=-13 of two equations together.
To find the result of multiplying these two equations, we need to use the distributive property. The distributive property states that a(b + c) = ab + ac. In this case, we can distribute the 7 and the 4 across the equations:
7(7x + 3y) = 7(-8)
4(4x - y) = 4(-13)
Simplifying these equations gives us:
49x + 21y = -56
16x - 4y = -52
Now, we can combine like terms:
65x + 17y = -108
This is the result of multiplying the two equations together. We can check our work by plugging in values for x and y and seeing if the equation holds true. For example, if x = 1 and y = 2, then the equation becomes:
65(1) + 17(2) = -108

Answers
Therefore, it will take John 4 hours to catch up with Karabo.
What is equation?In mathematics, an equation is a statement that shows the equality of two expressions. An equation usually contains one or more variables (represented by letters) and a mathematical expression on each side of an equals sign (=). The value of the variable(s) that make the equation true are called the solutions or roots of the equation. Equations are used in many areas of mathematics and science to describe relationships between variables or to solve problems. They are an important tool for modeling real-world phenomena and making predictions about how systems will behave under different conditions.
Here,
Let's call the time it takes for John to catch up with Karabo "t" (measured in hours).
In the hour that Karabo has been driving, she has covered a distance of:
distance = speed x time = 80 km/h x 1 h = 80 km
When John starts driving, he is behind Karabo by this distance. However, he is driving faster, so he will catch up to her eventually.
We can set up an equation to represent this situation:
distance covered by John = distance covered by Karabo
We know that John's distance is equal to his speed multiplied by the time he drives:
distance covered by John = 100 km/h x t
We also know that Karabo's distance is equal to the distance she covered in the hour before John started driving, plus the distance she covers during the time it takes John to catch up with her:
distance covered by Karabo = 80 km + 80 km/h x t
Now we can set these two expressions equal to each other and solve for t:
100 km/h x t = 80 km + 80 km/h x t
100 km/h x t - 80 km/h x t = 80 km
20 km/h x t = 80 km
t = 80 km / 20 km/h
t = 4 hours

To change these equations into y=mx+b form, we must first rearrange the equations.
For the first equation, 2x-4=8, we can move the 4 to the other side of the equation, giving us 2x = 12. We can then divide both sides by 2, giving us x = 6. So the equation is now in the form y=mx+b, where m is 2 and b is -4.
For the second equation, -2x+4y=-8, we can move the -2x to the other side of the equation, giving us 4y=-8-2x. We can divide both sides by 4, giving us y=-2-0.5x. So the equation is now in the form y=mx+b, where m is -0.5 and b is -2.
Now that both equations are in y=mx+b form, we need to compare their m and b values to determine if there is one solution, no solution or infinite solutions. We can see that m for both equations is different, so this means that the two equations are not the same, and there is no solution. This means that the two equations have no solution.

What is the possible range of y-values that, along with x=-4, form a solution to the following inequality? 10x-3y>-4
Answers
The possible range of y-values that form a solution to the inequality along with x=-4 is y<-12
The possible range of y-values that, along with x=-4, form a solution to the inequality 10x-3y>-4 can be found by isolating y on one side of the inequality. Here are the steps to do so:
1. Start with the given inequality: 10x-3y>-4
2. Plug in x=-4: 10(-4)-3y>-4
3. Simplify the left side of the inequality: -40-3y>-4
4. Add 40 to both sides of the inequality: -3y>36
5. Divide both sides of the inequality by -3 and reverse the inequality sign: y<-12
Therefore, the possible range of y-values that form a solution to the inequality along with x=-4 is y<-12. This means that any value of y that is less than -12 will satisfy the inequality when x=-4.

Step-by-step explanation:
To form a triangle, the two smaller lengths must be bigger than the largest side(Hopotonuse or sum, cant spell)
8 + 7 = 15
15>14
The possible lengths to complete a triangle with side lengths of 14 in. and 8 in. are 6 < x < 22.
What is Triangle Inequality?The triangle inequality theorem states that for any given triangle, the total of the two sides is always greater than the sum of the three sides. The Triangle is a polygon with three line segments as its boundaries. That is the tiniest polygon imaginable.
We have side lengths of 14 in. and 8 in.
Using Triangle inequality we know that the sum of two is greater than the third side.
Also, the range for third side is
14 + 8 = 22 inch
14 - 8 = 6 inch
So, the third side lies between as 6 < x < 22.

find the values x and y given : m is parallel to n, angle 4= 6x-5, angle 10 = 5x + 8, angle 9 = 3y - 10
Answers
Answer:
Without a diagram or additional context, it's difficult to determine the values of x and y precisely. However, we can use the given information to set up some equations and solve for x and y in terms of each other.
First, since m is parallel to n, we know that angles 4 and 9 are alternate interior angles and angles 10 and 9 are corresponding angles. Therefore:
angle 4 = angle 9 (alternate interior angles)
angle 9 + angle 10 = 180 degrees (interior angles on the same side of the transversal)
angle 4 + angle 10 = 180 degrees (corresponding angles)
Substituting the given expressions for each angle, we have:
6x - 5 = 3y - 10
5x + 8 + 3y - 10 = 180
6x - 5 + 5x + 8 = 180
Simplifying the second equation by combining like terms, we get:
8x + 3y - 2 = 0
We can now solve for one variable in terms of the other. From the first equation, we have:
6x = 3y + 5
x = (3/2)y + (5/6)
Substituting this expression for x into the third equation, we get:
6((3/2)y + (5/6)) - 5 + 5((3/2)y + (5/6)) + 8 = 180
Simplifying and solving for y, we get:
y = 29/9
Substituting this value for y back into the expression we found for x, we get:
x = (3/2)(29/9) + (5/6) = 59/6
Therefore, the values of x and y that satisfy the given conditions are x = 59/6 and y = 29/9.
Mika can eat 21 hot dogs in 6 minutes. She wants to know how many minutes it would tske her to eat 35 hot dogs if she can keep up the same pace. How many minutes would Mika need to eat 35 hot dogs?
Answers
We can use a proportion to solve the problem:
Let x be the number of minutes it would take Mika to eat 35 hot dogs
Then we can set up the proportion:
21 hot dogs / 6 minutes = 35 hot dogs / x minutes
To solve for x, we can cross-multiply:
21 hot dogs * x minutes = 6 minutes * 35 hot dogs
21x = 210
x = 10
Therefore, it would take Mika 10 minutes to eat 35 hot dogs if she can keep up the same pace.

Answers
A(n) = 3 + 7(n-1)
Step-by-step explanation:Arithmetic sequences have common differences and change by the same amount between each term.
Arithmetic Sequences
Arithmetic sequences change by the same amount each term. In the sequence above, each term increases by 7. This means that 7 is added to the previous term to make the new term. Using this information we can write a function to represent this sequence.
Explicit Rule
The function that describes an arithmetic sequence is known as an explicit rule. Explicit rules are written as A(n) = A(1) + d(n-1). In this equation, A(1) represents the first term in a sequence and d represents the common difference. As you can see, the first term is 3, so A(1) = 3. The common difference is the change between terms. The previous paragraph shows that the common difference for this sequence is 7.
This means the explicit rule for this sequence is A(n) = 3 + 7(n-1).

Answer:
24 antelopes, 36 monkeys
Step-by-step explanation:
6 : 7 means that for every 6 antelopes, there are 7 monkeys, so
a/6 = m/7 (1)
where a is the number of antelopes, m is the number of monkeys (before the 8 were born).
After 8 monkeys are born, the new ratio becomes:
a/2 = (m+8)/3 (2)
You can solve a and m for these two equations:
Rewrite (1) as 7a = 6m (cross product)
Rewrite (2) as 3a = 2m+16 (cross product)
=> 2m = 3a-16 (isolate 2m)
=> 6m = 9a-48 (multiply by 3)
Plug in (2) into (1):
7a = 9a-48 =>
-2a = -48
a = 24 antelopes
m = (a/6)*7 = 28 monkeys BEFORE the 8 newborns, so now there are
24 antelopes and 28+8=36 monkeys

What is currency conversion?Currency conversion can be stated as the process of converting one currency into another currency. This is usually done in order to make transactions or investments in another country or to keep track of the value of assets held in different currencies.
here, we have,
we know.
The value of one currency is generally expressed in terms of another currency using exchange rates, which means the value of one currency in terms of another currency at a specific point in time.
We know that, exchange rate can fluctuate over time, and currency conversion can be done manually or through various financial services or tools.
we have,
To calculate that how many pounds Brian will get for R2 100,
At first we need to calculate the amount of commission he will have to pay to the agent.
Commission = 1.5% of R2 100
Commission = 0.015 x R2 100
Commission = R31.50
Now we can calculate how much money Brian will have left after paying the commission:
Amount left after commission = R2 100 - R31.50
Amount left after commission = R2 068.50
Next, we can use the exchange rate given to convert Rands to Pounds:
1 Rand = 0.075199 Pounds
Therefore, to find out how many Pounds Brian will get for R2 068.50, we can multiply R2 068.50 by the exchange rate:
2 068.50 x 0.075199 = 155.605265 pounds
Next Part:
The price of petrol is increased from R12, 58 per litre to R13, 28 per litre.
i.e. increase of price = 100
so, the percentage increase in the price = 100 * 100/1258
=7.9%
Next Part:
A motor car drives at an average speed of 106 km/h.
the car travel in 2 hours 45 minutes = 106* 165 / 60
=291.5 km
So The solution is, after paying the agent commission, Brian will get 155.605265 pounds.
And, the percentage increase in the price 7.9%
the car travel in 2 hours 45 minutes is 291.5 km.

What happens to the value of the expression 100-x as x increases
Answers
The number 100-x has a decreasing worth as x rises.
What does a mathematical expression look like?A mathematical statement is referred to as an expression or an algebraic expression if it contains numbers, factors, and a numerical operation between them..For example, the arithmetic sign + separates the terms 4m and 5 from of the variable m in the expression 4m + 5..
The number 100-x has a decreasing worth as x rises. This is due to the fact that the phrase 100-x denotes a linear equation with a -1 slope. This indicates that the expression's value drops by one for each unit rise in x. As a result, the expression's value decreases as x increases. For instance, if x is 50, the expression's value is 50; however, if x is 70, the expression's value is 30. The meaning of the equation decreases in proportion to how much x increases.
