What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
Three congruent rectangles are joined as shown.
And, The length of each rectangle is 3 times its width.
Here, The area of each rectangle is 39 square units.
Let the length of the rectangle = 3x
And, The width of the rectangle = x
Hence, We get;
Area of rectangle = Length x Width
⇒ 39 = 3x × x
⇒ 39 = 3x²
⇒ x² = 13
⇒ x = √13
Hence, The length of the rectangle = 3√13
And, The width of the rectangle = √13
Thus, The perimeter of the figure is,
⇒ P = 3 × [ 2 (3√13 + √13) ]
⇒ P = 6 × 4√13
⇒ P = 24√13 units
Therefore, The perimeter of the shape formed is,
⇒ P = 24√13 units

If the quarterly interest at 10.5% is $3,150, the principal amount of a loan is
Answers
The principal amount of the loan is $1,200,000.
What is simple interest?
Simple interest is the amount of borrowing-related interest that is computed using only the initial principal and a constant interest rate.
To find the principal amount of a loan, we need to use the formula for simple interest:
I = Prt
Where I is the interest, P is the principal, r is the interest rate as a decimal, and t is the time in years.
In this case, we know that the interest is $3,150 and the interest rate is 10.5%. We also know that the interest is earned quarterly, so the time period is 1/4 of a year, or 0.25 years.
Substituting these values into the formula, we get:
3150 = P * 0.105 * 0.25
Solving for P, we get:
P = 3150 / (0.105 * 0.25) = $1,200,000
Therefore, the principal amount of the loan is $1,200,000.

Answers
Answer: Without a visual representation of the triangles, it's difficult to determine whether the statements are true or false.
However, in general, the side lengths of a triangle determine its shape and size. If two triangles have the same side lengths, then they are congruent, meaning they have the same shape and size. Therefore, if the triangles in question have different side lengths for x = 16, x = 27, and x = 31, then it's possible that the statements are either true or false, depending on the specific side lengths.

What is the probability of someone pulling 1-10 in consecutive order from a bad that contains 10 balls labeled 1-10?
Answers
The probability of someone pulling 1-10 in consecutive order from a bad that contains 10 balls labelled 1-10 is 1/3628800.
What is meant by probability?An event's probability is a numerical representation of how likely it is that the event will take place. In mathematical notation, it is written as a number between 0 and 1, or as a percentage between 0% and 100%. The higher an event's probability, the more likely it is to occur.
In a sample space, there is a probability of 1 for each event. The probability formula states that the ratio between the number of favourable outcomes and the total number of outcomes determines the likelihood that an event will occur. Sets are used in the terminology of probability theory. A set is a grouping of various things.
It is said that there are 10 balls in a bag, labelled 1-10.
Now,
The number of ways the ball labelled 1 is picked is 1
The number of ways the ball labelled 2 is picked is 2
So the number of ways a ball labelled certain number is picked is 1.
Now there is no replacement.
So the total number of balls decreases by 1 when 1 ball is taken.
Then,
The probability of choosing the ball numbered 1 = 1/10
The probability of choosing 2 = 1/9
The probability of choosing 3 = 1/8
.
.
.
the probability of choosing 10 = 1
Total probability of choosing the balls in consecutive order = 1/10 * 1/9 * 1/8 *.......* 1/2*1/1 = 1/10! = 1/3628800.
Therefore the probability of someone pulling 1-10 in consecutive order from a bad that contains 10 balls labelled 1-10 is 1/3628800.

The mean age of a family of seven is 23 years. The median is 16 years, the modes are 12, years and 45 years, and the range is 35 years. Find the ages of the seven family members
Answers
Let's use the given information to set up equations to solve for the ages of the family members.
We know that the mean age of the family is 23 years, so we can write:
(sum of ages) / 7 = 23
sum of ages = 161
We also know that the median age is 16 years, which means that the ages of the family members can be arranged in order from smallest to largest, and the middle age (or the average of the two middle ages, if there are an even number of ages) is 16. We can use this information to set up an equation:
(3rd smallest age + 4th smallest age) / 2 = 16
3rd smallest age + 4th smallest age = 32
Next, we know that the range of the ages is 35 years, which means that the difference between the largest age and the smallest age is 35. We can use this information to set up another equation:
largest age - smallest age = 35
Finally, we know that the modes (the most common ages) are 12 years and 45 years. This means that there are two family members whose ages are 12 years and two family members whose ages are 45 years. We can use this information to set up two more equations:
number of 12-year-olds + number of 45-year-olds = 4
12 x number of 12-year-olds + 45 x number of 45-year-olds = sum of ages
We now have five equations and five unknowns (the ages of the seven family members). We can solve for these unknowns using algebra. One possible set of ages that satisfies all of the equations is:
2, 2, 12, 16, 20, 45, 64
(Note that the ages do not have to be integers, but this particular set of ages happens to be integers and satisfies all of the given conditions.)

Who is correct? Verify your answer by giving all the necessary calculations (5 (5)
Answers
Therefore, John is incorrect, as buying a 2-liter bottle of orange juice is actually slightly more expensive per liter than buying a 1.5-liter bottle of cola.
What is equation?An equation is a mathematical statement that indicates the equality of two expressions. It consists of two expressions separated by an equal sign (=). The expression on the left side of the equal sign is equivalent to the expression on the right side. Equations can have one or more variables, which are usually represented by letters such as x, y, or z. The goal in solving an equation is to determine the value(s) of the variable(s) that make the equation true. This involves manipulating the expressions on both sides of the equal sign using algebraic operations such as addition, subtraction, multiplication, and division, to isolate the variable on one side of the equation. Equations are used in many areas of mathematics and science to represent relationships between variables and to solve problems. They are also used in various fields such as engineering, physics, and economics to model real-world situations and make predictions based on mathematical analysis.
Here,
2.1.1 To determine how many packets of patties Julia should buy, we need to know the total number of patties needed for the school function. Let's assume that each person will eat one patty.
If there are 300 people attending the function, then Julia needs to buy:
300 x 1 = 300 patties
Each packet of patties contains 12 patties, so the number of packets needed can be calculated as follows:
300 patties ÷ 12 patties/packet = 25 packets
Therefore, Julia should buy 25 packets of patties.
2.1.2 To justify Julia's calculation, we can use algebra. Let's assume that the number of packets of patties she buys is x. We know that there are 12 patties in each packet, so the total number of patties is 12x. We also know that if she buys 42 packets, there will be a leftover of 4 patties.
This can be represented as the following equation:
12x + 4 = 42 x 12
Simplifying this equation:
12x = 500 - 4 = 496
x = 496/12 = 41.33 (rounded to two decimal places)
Since we can't buy a fractional number of packets, Julia would need to buy 42 packets of patties. This would give her a total of:
12 x 42 = 504 patties
She would then have 4 leftover patties, as calculated earlier. Therefore, Julia's calculation is correct.
2.2.1 To determine whether buying a 2-liter bottle of orange juice is cheaper than buying a 1.5-liter bottle of cola, we need to compare the price per liter of each drink.
For orange juice, the price per liter is:
R18.95 ÷ 2 liters = R9.475/liter
For cola, the price per liter is:
R14.50 ÷ 1.5 liters = R9.67/liter

What is the finance charge on the loan?To find the finance charge on the loan, we need to first determine the amount financed. George Bell made a 15% down payment on the airplane, so the amount financed is:
= $29,200 - (0.15)($29,200)
= $29,200 - $4,380
= $24,820
The total amount of payments made over the life of the loan is:
= $579/month x 60 months
= $34,740
The finance charge on the loan is:
= $34,740 - $24,820
= $9,920.
What is the total deferred payment price of the airplane?The total deferred payment price of the airplane is the sum of the down payment and the total amount of payments made over the life of the loan. The down payment is 15% of the purchase price which is:
= 0.15 * $29,200
= $4,380
The total amount of payments made over the life of the loan is:
= $579/month * 60 months
= $34,740
The total deferred payment price of the airplane is:

An 18-inch-wide by 3-foot-deep trench is dug in the ground and a water line with a 3.5 inch outside diameter is placed in the trench. The water line is placed on 6 inches of bedding, and bedding surrounds the pipe to a height of 2.5 inches above the water line. The length of the trench is 500 feet. Determine the volume of excavation needed for the water line.
Answers
Answer: Here you go.
Step-by-step explanation:
To calculate the volume of excavation needed for the water line, we first need to calculate the cross-sectional area of the trench.
The trench has a width of 18 inches and a depth of 3 feet, or 36 inches. So the cross-sectional area of the trench is:
18 inches x 36 inches = 648 square inches
Next, we need to subtract the cross-sectional area of the water line from the cross-sectional area of the trench to get the area of the excavation. The water line has a 3.5 inch outside diameter, so the radius is 1.75 inches. The cross-sectional area of the water line is:
π x (1.75 inches)^2 = 9.62 square inches
The area of the excavation is therefore:
648 square inches - 9.62 square inches = 638.38 square inches
To convert square inches to cubic feet, we need to multiply by the length of the trench in feet. The length of the trench is 500 feet. So the volume of excavation needed for the water line is:
638.38 square inches x 500 feet = 1,909,140 cubic inches
To convert cubic inches to cubic feet, we divide by 12^3 (12 inches per foot, cubed):
1,909,140 cubic inches ÷ (12 x 12 x 12) = 11.04 cubic feet
Therefore, the volume of excavation needed for the water line is approximately 11.04 cubic feet.

x - y = 8 ---(2)
We can solve this system of equations by substitution method.
From equation (2), we have:
x - y = 8
Solving for x, we get:
x = y + 8
Substitute this value of x in equation (1):
y = (1/2)(y+8) + 4
Simplifying and solving for y, we get:
y = 2
Now, substitute this value of y back in equation (2) to find the value of x:
x - 2 = 8
x = 10
Therefore, the solution of the given system of equations is (x, y) = (10, 2).

A family has two cars. The first car has a fuel efficiency of 30 miles per gallon of gas and the second has a fuel efficiency of 35 miles per gallon of gas. During one particular week, the two cars went a combined total of 2425 miles, for a total gas consumption of 75 gallons. How many gallons were consumed by each of the two cars that week? (100 points!)
Answers
Answer:
Step-by-step explanation:
Let's assume that the first car used x gallons of gas during the week, then the second car used (75 - x) gallons of gas because the total gas consumption by both cars is 75 gallons.
The first car's fuel efficiency is 30 miles per gallon, so it traveled (30x) miles during the week.
The second car's fuel efficiency is 35 miles per gallon, so it traveled (35(75 - x)) miles during the week.
The total distance traveled by both cars is given as 2425 miles, so we can set up the equation:
30x + 35(75 - x) = 2425
Expanding the equation:
30x + 2625 - 35x = 2425
Simplifying:
-5x = -200
x = 40
Therefore, the first car used 40 gallons of gas during the week, and the second car used (75 - 40) = 35 gallons of gas during the week.
Answer: Car 1 used 40 gallons and car 2 used 35 gallons.
Step-by-step explanation: In this problem, we will use a system of equations to reach our answer. We can let x be the gallons consumed by the first car, and y be the gallons consumed by the second car(these are both for one particular week only). We know the total consumption of gas is 75 gallons so the gallons consumed by car 1 and car 2 have to add up to 75. We can then create the equation x+y=75. We know that car 1 has an efficiency of 30 miles per gallon and 35 miles per gallon for car 2. The miles produced by x gallons in car 1 can be represented by 30x=# of miles. we can use 35y = # of miles for car 2. We know the combined total of miles from both cars is 2425 so we can make the equation 30x+35y=2425 miles. Now that we have our equations, we can simply solve them to find our answers.
x+y=75
x=75-y Isolating a variable
30x+35y=2425
30(75-y)+35y=2425 Substituting the variable we isolated
2250-30y+35y=2425
2250+5y=2425
5y=175
y=35
x+(35)=75
x=40
y=35 and x=40
Car 1 used 40 gallons and car 2 used 35 gallons.

the ticket price needs to be lowered by approximately $8.33 in order to fill all seats in the stadium.
What is proportionality?the property of having suitable proportions in terms of size, number, degree, harshness, etc.: If a defensive action against an unfair attack results in the destruction that contravenes the proportionality criterion, it may even go far beyond a justifiable defense.
Given, A baseball team plays in a stadium that holds 58,000 spectators. With the ticket price at $10, the average attendance at recent games has been 33,000.
Let's assume that if the ticket price is lowered by $x, the corresponding increase in attendance is 3000x.
Then, if the ticket price is lowered by $x, the new attendance will be:
33,000 + 3000x
We want to find the ticket price that will result in full capacity, which is 58,000 spectators.
So, we can set the new attendance equal to 58,000 and solve for x:
33,000 + 3000x = 58,000
3000x = 25,000
x = 25,000/3000
x ≈ 8.33
Therefore, the ticket price needs to be lowered by $8.33 to $1.67 in order to fill all seats in the stadium.

The solution to the system of equations is given below.
What is function?A function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.
Given is the system of equations as shown in the image.
{ 1 } -
x - 2y = - 7
2x + 5y = 8
We can write -
x = 2y - 7
Now -
2(2y - 7) + 5y = 8
4y - 14 + 5y = 8
9y = 22
{y} = 22/9
x = 44/9 - 7
x = 44/9 - 63/9
{x} = - 19/9
{ 2 } -
5x - 3y = 16
3x + 6y = 18
We can write -
5x - 3y = 16
x + 2y = 9
So -
x = 9 - 2y
5(9 - 2y) - 3y = 16
45 - 10y - 3y = 16
45 - 13y = 16
45 - 16 = 13y
13y = 29
y = 29/13
x = 9 - 58/13
x = 117/13 - 58/13
x = 59/13
Similarly, we can solve the other two system of equations.
Therefore, the solution to the system of equations is given above.
