Answer: She will need 142 ft of curtain.
Step-by-step explanation:
Hi, first we have to convert the length of the curtain from inches to foot.
Since 1 inch = 1/12ft
For 24 inches:
24 inches x 1/12 = 2 ft
Since the company wants to make 71 curtains, we have to multiply the length of each curtain (2ft) by 71.
2ft x 71 = 142ft
She will need 142 ft of curtain.

Use the substitution method to solve the system of equations. 3x + 7y = 1 y = x – 7
A. (3, –4)
B. (4, –3)
C. (2, –5)
D. (5, –2)
Answer: The correct option is (D) (5, -2).
Step-by-step explanation: We are given to use the method of substitution to solve the following system of equations :
[tex]3x+7y=1~~~~~~~~~~~~~~~~~~~~~~~~~(i)\\\\y=x-7~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)[/tex]
Substituting the value of y from equation (ii) in equation (i), we get
[tex]3x+7y=1\\\\\Rightarrow 3x+7(x-7)=1\\\\\Rightarrow 3x+7x-49=1\\\\\Rightarrow 10x=50\\\\\Rightarrow x=\dfrac{50}{10}\\\\\Rightarrow x=5,[/tex]
and from equation (ii) again, we get
[tex]y=x-7=5-7=-2.[/tex]
Thus, the required solution is (x, y) = (5, -2).
Option (D) is CORRECT.
A taxi service charges $1.00 for the first 1/10 mile then $0.10 for each additional 1/10 mile after that.
Answer:
y = 1.00+0.10 x
Step-by-step explanation:
Given that a taxi has a minimum charge of 1 dollar upto 1/10 mile and adds 0.10 for every additional 1/10 mile.
If a person travels <=1/10 miles his charges are 1 dollar
If he travels >1/10 miles charges are 1 dollar +0.10(extra miles 1/10)
Let y be the charges and x be the no of 1/10 miles.
Then the equation for y in terms of x would be
y =1.00 +1/10(x)
y = 1.00+0.10 x

The cost of coffee is determined by the type of coffee beans that are mixed together. The cost of a local mix of arabica and robusta beans is modeled by the equation below, where a = the pounds of arabica and r = pounds of robusta: (2 points) 700a + 1200r = 1,000,000 if a mixture contains 1000 pounds of arabica beans, how many pounds of robusta beans should be in the mixture? R = pounds
700a + 1200r = 1,000,000
700(1000) + 1200r = 1,000,000
700,000 + 1200r = 1,000,000
1200r = 300,000
r = [tex]\frac{300,000}{1200} = \frac{3000}{12} = 250[/tex]
Answer: 250 pounds of robusta beans
Does This. Graph Represent A Function? Why Or Why Not?
Answer: D. Yes because it passes the vertical line test.
Step-by-step explanation
A function cannot have duplicate x-coordinates.
When given a table or a set of coordinates, if there is an x-coordinate that is paired with two different y-coordinates then it is not a function.
When given a graph, the simplest way to determine if it is a function is to use the vertical line test. If you can draw a vertical line anywhere through the graph and it passes through two points, then it is not a function.
In the given graph, it passes the vertical line test so it IS a function.

Which methods can be used to expand (x+3)3?
Which methods can be used to expand (x+3)3?
Solution
Here use the Distributive Property of Multiplication Across the Addition.
The Distributive Property is a.(b + c) = a. b + a.c
Using the distributive property, we can expand the given expression.
(x + 3).3 = 3.x + 3.3
That is the expanded form.
The expression (x+3)³ can be expanded by using the binomial expansion method or by multiplying (x+3) by itself three times. This involves using binomial coefficients and combining like terms or calculating the products directly and simplifying the resulting expression.
To expand (x+3)³, we can use binomial expansion, which involves recognizing the pattern of coefficients that arise from Pascal's Triangle or using the binomial theorem. Another way is to multiply (x+3) by itself three times. In both methods, you calculate the products and combine like terms to get the final expanded form.
For cubing of exponentials, such as cubing (x+3), you must calculate each term of the binomial raised to the third power and then combine like terms. The cube of the digit term is calculated as usual, and you multiply the exponents by 3 when dealing with exponential terms.
An example of this concept applied to individual exponentials is: (5³)⁴ = 5³*⁴ = 5¹². In our case of binomial expansion, the expanded form of (x+3)³ would be x³ + 3*x²*³ + 3*x*3² + 3³, which simplifies to x³ + 9*x² + 27*x + 27.

2x2 - 3x - 2 = x + 4.check all of the solutions to this equation.-137(–1, 3)(3, 7)
Answer:
-1 and 3
Step-by-step explanation:
The equation can be solved using the quadratic formula, resulting in two possible solutions: x = (-3 + √25) / 4 and x = (-3 - √25) / 4.
Explanation:This equation can be solved using the quadratic formula. For an equation of the form ax² + bx + c = 0, we rearrange it to 2x² - 3x - 2 = x + 4.
Now, using the quadratic formula, we can solve for the values of x:
x = (-b ± √(b² - 4ac)) / (2a)
Substituting the values a = 2, b = -4, and c = -6 into the formula, we get:
x = (-(-3) ± √((-3)² - 4(2)(-2))) / (2(2))
After simplification, we have x = (-3 ± √(9 + 16)) / 4
Which gives us two solutions: x = (-3 + √25) / 4 and x = (-3 - √25) / 4

Please help!!!!!!!!!!!!!!!!!!!!!!!!! 100 points!
Answer:
Your answer is B or option 2.
Step-by-step explanation:
When doing scale factors, you will multiply. Always. To get from the original box to the second box, you will multiply by a scale factor of 5/8. An equation can model this. b=5/8a. (Let a = dimensions of original/blue box, let b = dimensions of second/green box).
Since you need to find the dimensions of the first/original box, you need to change b=5/8a to a= [something]. To do that, divide both sides by 5/8. You have b / 5/8 = a. The dimensions of the second box divided by the scale factor 5/8 is the dimensions of the first box. This also makes sense, because the green box looks smaller than the blue box. Hope I helped! This is a challenging subject to explain properly. ^_^"
oh yeah kekeke my name is pizaz/pzaz, what a coinkidink
The answer is D.
Since the original rectangle is bigger, we are going to divide the dimensions in the smaller triangle by the scale factor 5/8. An easy hint to look at in this question is an answer choice that both dimensions are bigger than the dimensions of the smaller rectangle. All the other choices are incorrect because the dimensions of the original triangle are not bigger than that of the smaller triangle which makes them false.

Enter a recursive rule for the geometric sequence.
2, 6, 18, 54, …
a1= ; an=
Answer:
Step-by-step explanation:
Given a geometric sequence.
2, 6, 18, 54, …
We have to find the I and nth term.
A geometric sequence. is one where each term is multiplied by a constant value to get the next term.
In our sequence, we find the pattern as each term is multiplied by 3 to get successive terms.
Hence common ratio r = 3
First term = a = 2
For Geometric sequence nth term = a_n = ar^(n-1)
Hence we get a_1 = 2
and a_n = 2(3)^(n-1)
By substituting for n any natural number we can get that term.

If you are F years old and your brother is B years older, then your brother is F+B years old. Add your age (F) and your brother's age (F+B) and you get F+(F+B) = 2F+B
The sum of your ages is 2F+B
where F and B are placeholders for numbers.
