The surface area is ? square feet.
By answering the presented question, we may conclude that As a result, surface area the prism's surface area is 640 square feet.
what is surface area ?The surface area of an object indicates the overall space occupied by its surface. The surface area of a three-dimensional form is the entire amount of space that surrounds it. The surface area of a three-dimensional form refers to its full surface area. By summing the areas of each face, the surface area of a cuboid with six rectangular faces may be computed. As an alternative, you may use the following formula to name the box's dimensions: 2lh + 2lw + 2hw = surface (SA). Surface area is a measurement of the total amount of space occupied by the surface of a three-dimensional form (a three-dimensional shape is a shape that has height, width, and depth).
To get the surface area of the prism, sum the areas of all six faces.
The top and bottom rectangular faces have the same size and area:
10 feet x 8 feet = 80 square feet
The dimensions of the other four faces are the same:
12 feet tall x 10 feet wide = 120 square feet
As a result, the total surface area is:
2 (80 square feet) + 4 (120 square feet) = 160 square feet + 480 square feet = 640 square feet
As a result, the prism's surface area is 640 square feet.

Tom and John are engaged in buying and selling certain products A and B. Tom BUYS 5 of product A but
SELLS twice as much of product B. John on the other hand SELLS three times what Tom BOUGHT of
product A and BUYS 13 of product B. At the end of the business day, John banks Ksh 110,000/- while
Tom banks Ksh 230,000.
Under the assumption that the sale prices for product A and B are the same for the two men, and the
costs prices for the products A and B are also the same for the two men, obtain the following:
a) The price for product A and the price for product B (5 marks)
b) If there was a mark up of 25% on the cost price and a discount of 15% on the sale price, how
much would each of the partners have banked at the end of the business day? (10 marks)
Answer:Let's assume that the cost price for both products A and B is "C", and the selling price for both products A and B is "S". We can use this information to set up two equations, one for Tom and one for John, that relate the costs and profits for the two products:
Tom: 5C - 2(5S) = P1
John: 3(5C) - 13C = P2
where P1 and P2 are the profits made by Tom and John, respectively.
We know that at the end of the business day, John banks Ksh 110,000/- while Tom banks Ksh
230,000. So we can write:
P1 = 230,000 - 5C
P2 = 110,000 - 18C
Substituting these values into the equations for Tom and John, we get:
5C - 2(5S) = 230.000 - 5C
Simplifying these equations, we get:
10C - 10S = 230,000
2C = 110,000
Solving for C, we get:
C = 55,000
Substituting this value back into the first equation, we can solve for S:
10(55,000) - 10S = 230,000
Simplifying this equation, we get:
S = 32,000
Therefore, the price for product A is Ksh 55,000 and the price for product B is Ksh 32,000.

18. The florist charges $31.75 for eight roses and five carnations. For one rose and three
carnations, if costs $5.75. What is the cost for a carnation? (Solving systems of equations applications)
Answer: Let's use the variables "r" and "c" to represent the cost of one rose and one carnation, respectively.
From the first sentence, we know that 8 roses and 5 carnations cost $31.75. So we can write the equation:
8r + 5c = 31.75
From the second sentence, we know that 1 rose and 3 carnations cost $5.75. So we can write the equation:
r + 3c = 5.75
Now we have two equations with two variables. We can use substitution or elimination to solve for "c". Let's use substitution:
r = 5.75 - 3c (from the second equation)
Substitute this expression for "r" into the first equation:
8(5.75 - 3c) + 5c = 31.75
Simplify and solve for "c":
46 - 24c + 5c = 31.75
-19c = -14.25
c = 0.75
Therefore, the cost for a carnation is $0.75.

The equation for the volume of the rectangular prism is V = x³ + 2x² - 8x.
What is a rectangular prism?A three-dimensional solid structure called a rectangular prism contains six rectangular faces, each of which is perpendicular to the faces around it. The term "rectangular parallelepiped" is another name for it. Rectangular prisms are frequently employed in geometry because they may be used to represent a variety of real-world objects, including boxes, buildings, and rooms. A rectangular prism's surface area is equal to the total of the areas of its six faces, whereas its volume is determined by the product of its length, breadth, and height.
The volume V of a rectangular prism is given by the formula:
V = lwh
Substituting the values:
V = (x + 4)(x - 2)(x)
= (x² + 2x - 8)(x)
= x³ + 2x² - 8x
Hence, the equation for the volume of the rectangular prism is V = x³ + 2x² - 8x.

In a particular country, there are 11 200 registered female soccer players and 14 000 registered male soccer players.
In another country, there are 10 400 registered female soccer players and 13 000 registered male soccer players.
Is the ratio of female players to male players the same for both countries?
To determine if the ratio of female players to male players is the same in both countries, we need to calculate the ratios and compare them.
For the first country,
let female players be f1,male players be m1
the ratio of female players to male players is:f1:m1 (i.e f1/m1)
11,200 / 14,000 = 0.8
For the second country,
let female players be f2,male players be m2
the ratio of female players to male players is:f2:m2 (i.e f2/m2)
10,400 / 13,000 = 0.8
As we can see, both ratios are the same, which means that the ratio of female players to male players is the same in both countries. Therefore, we can conclude that there is no significant difference in the gender ratio of soccer players between these two countries.
Answer:
The female-to-male ratios for both countries are the same (0.8), indicating that the ratio of female players to male players is the same for both countries.
Explanation:
To determine whether the ratio of female players to male players is the same for both countries, we need to calculate the ratio of female players to male players for each country and compare them.
Country 1: Female-to-male ratio
= 11,200 / 14,000
= 0.8
Country 2: Female-to-male ratio

A. 62/12
B. 58/12
C. 55/12
D. 3/12
Answer:
The given expression is,
-1/6+2/3(9-3/4)-1/2
According to BODMAS rule, we first do the operation of bracket ( as B comes first in the BODMAS).
∴ 9-3/4= (36-3)/4=33/4
Putting 33/4 in place of (9-3/4), the expression becomes
-1/6+2/3×33/4-1/2
Now, the priority of M in BODMAS is more than A and S, so we do the operation of multiplication.
∴2/3×33/4=11/2 ( as 33÷3=11 and 4÷2=2)
Replacing 2/3×33/4 by 11/2, the expression becomes,
-1/6+11/2-1/2
= -1/6+(11-1)/2
= -1/6+5
= (-1+30)/6
=29/6
Hence the value of the given expression is 29/6.

Find each length below.
a) The length of the secant segment [tex]HC = 31.5[/tex].
b) The length of the secant segment [tex]XY = 4.8[/tex]
What is the secant segment?In geometry, a secant is a line that intersects a circle at two distinct points. A secant segment is part of a secant that lies between its two points of intersection with the circle.
In geometry, a segment is part of a line that is bounded by two distinct endpoints. A segment can be straight or curved. Straight segments are also called line segments, and curved segments are also called arcs.
According to the given information
a) In the figure, HG is a tangent and HD is a secant to the circle, and HC is the length of the secant segment.
We know that the product of the lengths of the two segments of a secant from an exterior point to a circle is equal to the product of the lengths of the entire secant and its external segment. That is,
[tex]HD*HE =HG^{2}[/tex]
where [tex]HE[/tex] is the length of the external segment of the secant.
Substituting the given values, we get:
[tex]31.5*HE =21^{2}[/tex]
[tex]HE = 21^{2} /31.5 = 14[/tex]
Now, we can use the same property to find [tex]HC[/tex]. That is,
[tex]HC *HE =HG^{2}[/tex]
Substituting the values we have found, we get:
[tex]HC*14 = 21^{2} \\HC = 21^{2} /14 = 31.5[/tex]
Therefore, the length of the secant segment [tex]HC = 31.5[/tex].
b) [tex]VX*VZ= VY*VW[/tex]
Substituting the given values, we get:

Any expression that involves only integers and basic Arithmetic operations can simplify to a rational answer, while expressions involving irrational numbers cannot.
There are several expressions that simplify to a rational answer. In mathematics, a rational number is any number that can be expressed as the ratio of two integers, where the denominator is not zero. Therefore, any expression that involves only integers, addition, subtraction, multiplication, and division can simplify to a rational answer.
For example, if you have an expression like (3 + 2)/(4 - 1), this can be simplified to 5/3, which is a rational number. Similarly, expressions like 6/3 or 7 - 2 also simplify to rational answers.
However, expressions that involve irrational numbers such as pi or the square root of 2 cannot simplify to rational answers. For example, the expression sqrt(2) + 3 cannot be simplified to a rational number.
In summary, any expression that involves only integers and basic arithmetic operations can simplify to a rational answer, while expressions involving irrational numbers cannot.

If f (x) = 3x, g (x) = x + 4, and h (x) = x^2 - 1, find [fo(hog)] (1)
Answer:
Step-by-step explanation:
To find [fo(hog)] (1), we need to first evaluate the composition hog at x = 1, and then plug the result into f.
Let's start by evaluating hog at x = 1:
hog(x) = h(g(x)) = h(x + 4) = (x + 4)^2 - 1
So, hog(1) = (1 + 4)^2 - 1 = 24
Now we can evaluate f at hog(1):
f(hog(1)) = f(24) = 3(24) = 72
Therefore, [fo(hog)] (1) = 72.

The students at Woodward Elementary voted for a school mascot. The falcon won with 5/8 of the votes and the eagle came second with 1/3 of the remaining votes. If 536 students voted for a mascot, how many students voted for the eagle
Approximately 75 students voted for the eagle.
Define fractionA fraction is a numerical quantity that represents a part of a whole or a quotient of two numbers. It consists of two numbers separated by a horizontal or diagonal line called a fraction bar or a division bar.
The falcon won with 5/8 of the votes, which means that 3/8 of the votes were for the other candidates (since 5/8 + 3/8 = 1).
Let's represent the total number of votes as "x".
Then, the number of votes for the falcon is (5/8)x and the number of votes for the other candidates is (3/8)x.
Out of these other candidates, the eagle received 1/3 of the votes. So, the number of votes for the eagle is:
(1/3)(3/8)x = (1/8)x
We know that the total number of votes is 536, so we can set up the equation:
(5/8)x + (3/8)x + (1/8)x = 536
Simplifying the equation, we get:
(9/8)x = 536
Multiplying both sides by 8/9, we get:
x = 596
Therefore, the number of votes for the eagle is:
(1/8)x = (1/8)(596) = 74.5
Therefore, approximately 75 students voted for the eagle.

4. Next, we need to perform the division, which means we need to divide 3/2 by 12. To do this, we can rewrite 12 as a fraction with a denominator of 2: 12/1 x 1/2 = 6/1. Then, we can simplify 3/2 divided by 6/1 by multiplying by the reciprocal of 6/1: (3/2) x (1/6) = 1/4.
5. Now we can substitute this value back into the expression: 8 15/22 - 1/4.
6. Finally, we need to convert the mixed number 8 15/22 to an improper fraction: 8 x 22/22 + 15/22 = 181/22.
7. Now we can combine like terms: 181/22 - 1/4 = (181 x 4)/(22 x 4) - 1/4 = 724/88 - 22/88 = 702/88.
8. We can simplify the fraction by dividing both the numerator and denominator by the greatest common factor (GCF), which is 2: 702/88 = 351/44.
Therefore, 8 15/22 - 3/4 x 2 divided by 12 is equal to 351/44.

Determine whether the pair of functions are inverses functions
the given pairs of functions are inverse of each other.
A function that can reverse into another function is known as an inverse function or anti-function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y. When a function is written as "f" or "F," its inverse is written as "f-1" or "F-1." Here, (-1) should not be confused with an exponent or a reciprocal.
We have two function
f(x) = √(x+4)+9
let y=√(x+4)+9
y-9=√(x+4)
(y-9)²=x+4
x=(y-9)²-4
inverse of f(x) is (x-9)²-4
Now for g(x)= (x-9)²-4
The inverse of g(x)
will be f(x) = √(x+4)+9
Hence the given pairs of function is inverse of each other

The combination of goods that would maximize the consumer's Utility per dollar leads to a utility equal to 14 utils.
To determine the combination of goods that would maximize the consumer's utility per dollar, we need to use the concept of marginal utility. Assuming that the consumer has $14 to spend and chips cost $1 while soda costs $2, the consumer could purchase either 14 chips, 7 sodas or a combination of the two.
Let's say the consumer decides to buy x chips and y sodas. The total expenditure would be 1x + 2y, and the total utility would be the sum of the marginal utility of each good multiplied by the quantity purchased.
Assuming the utility function is U(x, y) = x^(1/2) * y^(1/2), the marginal utility of chips would be (1/2)x^(-1/2)*y^(1/2) and the marginal utility of soda would be (1/2)x^(1/2)*y^(-1/2).
The consumer's goal is to maximize the utility per dollar, which is calculated as the total utility divided by the total expenditure. Therefore, the utility per dollar function would be U(x, y)/(1x + 2y).
Using the Lagrange multiplier method, we can find the combination of x and y that maximizes the utility per dollar. The first-order conditions give us the following system of equations:
(1/2)x^(-1/2)*y^(1/2) = λ
(1/2)x^(1/2)*y^(-1/2) = 2λ
x^(1/2)*y^(1/2) = 14
Solving this system of equations, we get x = 4 and y = 49/4. Therefore, the consumer should buy 4 chips and 12.25 sodas, which costs $29.50.
The utility function evaluated at this point is U(4, 49/4) = (4^(1/2))*(49/4)^(1/2) = 14. The utility per dollar function evaluated at this point is U(4, 49/4)/(1(4) + 2(49/4)) = 14/29.50 = 0.4746.
Therefore, the combination of goods that would maximize the consumer's utility per dollar leads to a utility equal to 14 utils.

O D.
The first difference is constant.
The second difference is constant in quadratic number patterns. The correct option is C
What is Quadratic number patterns?
Quadratic number patterns are sequences of numbers that follow a quadratic or second-degree pattern or rule. This means that the sequence is generated by adding a constant difference between terms, which is itself increasing or decreasing linearly.
A quadratic sequence can be defined by a formula of the form :
an = a + bn + cn^2
Where
"an" is the nth term of the sequence, "a", "b", and "c" are constants, "n" is the position of the term in the sequence (starting with n=1).Therefore, the correct option is C

Evaluate the function using the Maclaurin series
we use the first four terms, we get: equation.
[tex]f(x) =x^2 + x^3 + x^4/2! + x^5/3![/tex]
And so on.
What is Maclaurin series?A Maclaurin series, named after the Scottish mathematician Colin Maclaurin, is a special type of power series expansion of a function that is centered at zero. In other words, it is a way to represent a function as an infinite sum of terms that involve the function's derivatives evaluated at zero.
The general form of a Maclaurin series for a function f(x) is given by:
[tex]f(x) = f(0) + f'(0)x + (f''(0)/2!)x^2 + (f'''(0)/3!)x^3 + ...[/tex]
To evaluate the function f(x) = x^2 * [tex]e^x[/tex] using Maclaurin series, we can first find the Maclaurin series for [tex]e^x[/tex] and then multiply it with x^2 to obtain the Maclaurin series for f(x).
The Maclaurin series for [tex]e^x[/tex]is given by:
[tex]e^x = 1 + x + x^2/2! + x^3/3! + x^4/4! + ...[/tex]
Multiplying both sides by x^2, we get:
[tex]x^2 * e^x = x^2 + x^3 + x^4/2! + x^5/3! + x^6/4! + ...[/tex]
Therefore, the Maclaurin series for f(x) is:
[tex]f(x) = x^2 * e^x = x^2 + x^3 + x^4/2! + x^5/3! + x^6/4! + ...[/tex]
To approximate the value of f(x) using the Maclaurin series, we can truncate the series after a certain number of terms. The more terms we include, the more accurate the approximation will be. For example, if we use the first three terms of the series, we get:
[tex]f(x) = x^2 + x^3 + x^4/2![/tex]
