Answer: 9

Step-by-step explanation:

The factors of 18: 1, 2, 3, 6, 9, 18

The factors of 27: 1, 3, 9, 27

The GCF of 18 and 27 is 9. This means that 9 is the largest number that can evenly divide both 18 and 27 without leaving any remainder.

Step 1: Find the Factors of Each Number

To find the factors of a number, you identify all the whole numbers that divide that number without leaving a remainder. Here are the factors of 18 and 27:

Factors of 18: 1, 2, 3, 6, 9, 18

Factors of 27: 1, 3, 9, 27

Step 2: Identify the Common Factors

Next, we look for the common factors between the two sets of factors. These are the numbers that appear in both lists:

Common factors of 18 and 27: 1, 3, 9

Step 3: Determine the Greatest Common Factor (GCF)

The GCF is the greatest or largest number among the common factors. In this case, the greatest common factor among 1, 3, and 9 is 9.

Therefore, the GCF of 18 and 27 is 9. This means that 9 is the largest number that can evenly divide both 18 and 27 without leaving any remainder.

Answer:

$1,325

Step-by-step explanation:

All we have to do is to identify which amount is the goal, and which amount(s) are taken steps toward that goal. Once you identify those, deduct whatever amount(s) that have got you closer to the goal and you will get what is still left to achieve. Or as stated in this example, the open-to-buy amount.

Goal:

$3,500 (as planned)

Steps made toward reaching planned goal:

Orders Received: $975

Merchandise ordered: $1,200

Compute the goal minus the steps achieved so far and Voila! You will get your open-to-buy amount.

Answer:

[tex]y=-2cos (2(x+\pi ))-1[/tex]

Step-by-step explanation:

From the graph, we can see that y = -3 when x  = 0.

So to check whether which of the given options is the equation of the given graph, we will set our calculator to the radian mode and then plug the value of x as 0.

1. y = -2 cos (4(x + pi)) - 1 = -2 cos (4(0 + pi)) - 1  = 3

2. y = 2 cos(x + pi) = 2 cos(0 + pi) = -1

3. y = -2 cos (2(x + pi)) - 1 = -2 cos (2(x + pi)) - 1 = -3

Therefore, the equation of this graph is  y = -2 cos (2(x + pi)) - 1.

To ensure Trisha has at least 5 times as many key chains as thumb drives in each gift bag, the inequality x ≥ 5y can be used, where x is the number of key chains and y is the number of thumb drives. Considering she needs to make at least 50 bags, the inequality x + y ≥ 50 is also relevant.

For Trisha to satisfy the condition of having at least 5 times as many key chains as thumb drives in each gift bag, the following inequality can represent her situation:

x ≥ 5y

Here, x is the number of key chains and y is the number of thumb drives. Trisha must also create at least 50 gift bags, so another inequality to consider is the total number of gift bags:

x + y ≥ 50

Since Trisha has 25 thumb drives (y) and 200 key chains (x), she is limited by the number of thumb drives. The maximum number of gift bags she can create with one thumb drive in each is 25 bags, which means she can use up to 125 key chains (5 times 25). Thus, Trisha can satisfy the requirement by using all 25 thumb drives and up to 125 key chains, ensuring there's a minimum of one thumb drive or key chain per bag.

Final answer:

To find out how much dressing remains in the jar, subtract the amount of dressing poured onto the salad from the total amount of dressing made.

Explanation:

To find out how much dressing remains in the jar, we need to subtract the amount of dressing poured onto the salad from the total amount of dressing made.

Dakota combines 6 1/3 fluid ounces of oil and 2 3/8 fluid ounces of vinegar, which gives us a total of 8 17/24 fluid ounces of dressing.

She pours 2 1/4 fluid ounces of the dressing onto her salad. To find out how much dressing remains, we need to subtract 2 1/4 from 8 17/24. Converting the fractions to a common denominator, we have (55/24) - (9/4) = 46/24 - 9/4 = 37/24. This means that 37/24 fluid ounces of dressing remain in the jar.

Answer:

x=9

Step-by-step explanation:

-9x + 1 = -80

-9x = -81           substract 1 from both sides

x= 9                  divide both sides by -9

The solution to the equation -9x + 1 = -80 is x = 9

To solve the equation -9x + 1 = -80, we aim to isolate the variable x on one side of the equation.

First, we can subtract 1 from both sides to get rid of the constant term:

-9x + 1 - 1 = -80 - 1

This simplifies to:

-9x = -81

Next, we divide both sides by -9 to solve for x:

(-9x) / -9 = (-81) / -9

This gives us:

x = 9

Therefore, the solution to the equation -9x + 1 = -80 is x = 9. When we substitute x with 9 in the original equation, we get -9(9) + 1 = -80, which is true, confirming the solution.

The best first step to solve the given equation is to add the first equation to the second equation.

In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.

Given that are two equations, x+y=3 and 4x-y=7

To solve them we will use elimination method, because, in both equations coefficients of y are -1 and +1, if we will add them they will get cancelled, leaving x alone, that will help us find the value of x easily.

The easiest way to get this is through divide and conquer.

Therefore take 1, 2, 3, 5, 7, 9, and 11.

1 is a factor obviously.

2 is a factor since 80 is divisible by 80. We found a factor so divide the value 80 by 2 and we get 40. Is 2 a factor of 40? Yep, so divide again and we have 20. Is 2 a factor of 20. Yep. So is 10. So now we are at 5. But 5 is not a factor of 2. 5 is a factor of 5.

So we have the following 1, 2, 2, 2, 2, and 5. Thus 2 and 5 are your prime factors of 80. Note this is NOT the prime factorization of the number 80. That value is 2^4 * 5. You asked the prime factors of 80. Those are 2 and 5.

Answer:

- 4x² + 10x

Step-by-step explanation:

(f - g)(x) = f(x) - g(x)

= - x² + 6x - 1 - (3x² - 4x - 1) ← distribute

= - x² + 6x - 1 - 3x² + 4x + 1 ( collect like terms )

= - 4x² + 10x

Final answer:

To find f-g (x), subtract g(x) from f(x) and combine like terms. The resulting function is f-g (x) = -4x² + 10x.

Explanation:

To find the difference of the functions f(x) and g(x), denoted as f-g (x), we simply subtract the function g(x) from f(x). In the given problem:

f(x) = -x² + 6x - 1

g(x) = 3x² - 4x - 1

We subtract the expressions:

f-g (x) = (-x² + 6x - 1) - (3x² - 4x - 1)

Removing the parentheses and simplifying, we get:

f-g (x) = -x² + 6x - 1 - 3x² + 4x + 1

Combine like terms:

f-g (x) = -4x² + 10x

Thus, the function f-g (x) is -4x² + 10x.

Answer:

$2.29

Step-by-step explanation:

She spent the $50.00 gift certificate plus $0.33.

$50.00 + $0.33 = $50.33.

She spent a total of $50.33.

The pajamas cost $17.97.

The necklace cost $25.49.

The total cost of the pajamas and necklace is:

$17.97 + $25.49 = $43.46.

Since she spent a total of $50.33, we now subtract the amount she spent on the pajamas and necklace to find out the cost of the three pairs of socks.

$50.33 - $43.46 = $6.87

The three pairs of socks cost a total of $6.87.

Since all pairs of socks cost the same amount, we now divide $6.87 by 3 to find the price of each pair of socks.

$6.87/3 = $2.29

Each pair of socks costs $2.29.

[tex]\frac{19}{4}ft\frac{12in}{1ft}=57in[/tex]

As you can see, the choice A is not the right answer because is more than 53.

We do the same process. We know that,  [tex]4\frac{1}{2}=\frac{9}{2}ft[/tex] how much inches would be?

[tex]\frac{9}{2}ft\frac{12in}{1ft}=54in[/tex]

Choice B is not the answer neither, because it's outside the interval.

[tex]4\frac{1}{4}=\frac{17}{4}ft[/tex] how much inches would be?

[tex]\frac{17}{4}ft\frac{12in}{1ft}=51in[/tex]

To solve this problem, we first need to figure out how much tax will be applied to Neil's purchase.  To do this, we need to multiply the tax rate (5%) by the cost of the washing machine ($445).  But, we can't multiply percentages unless we change them to decimal form first.  To do this, we need to divide the percentage by 100 (because 5 percent is a fraction out of a  total 100 percent) or move the decimal point two spots to the left.  This gives us the following:

0.05 * 445

If we compute this expression, we get:

$22.25

This means that Neil will be charged $22.25 in tax.  However, the question asks for the total cost including tax, so we must add the original cost of the washing machine to the tax.  

$445 + $22.25 = $467.25

Therefore, your answer is $467.25.

The correct measure of angle 2 is [tex]\( m\angle2 = 130\°\)[/tex].

To find the measure of angle 2, we need to use the properties of parallel lines and the angles formed when a transversal intersects them. When a transversal intersects two parallel lines, corresponding angles are equal, and alternate interior angles are also equal.

In the given scenario, lines b and c are parallel, and we assume that the transversal intersects these parallel lines at points not shown in the conversation. Let's denote the angles formed by the intersection of the transversal with line b as angles 1, 2, 3, and 4, and with line c as angles 5, 6, 7, and 8, respectively.

Since lines b and c are parallel, we have the following relationships:

1. [tex]\( m\angle1 = m\angle5 \)[/tex] (corresponding angles)

2. [tex]\( m\angle2 = m\angle6 \)[/tex] (corresponding angles)

3. [tex]\( m\angle3 = m\angle7 \)[/tex] (corresponding angles)

4. [tex]\( m\angle4 = m\angle8 \)[/tex] (corresponding angles)

5. [tex]\( m\angle1 = m\angle8 \)[/tex] (alternate interior angles)

6. [tex]\( m\angle2 = m\angle7 \)[/tex] (alternate interior angles)

7. [tex]\( m\angle3 = m\angle6 \)[/tex] (alternate interior angles)

8. [tex]\( m\angle4 = m\angle5 \)[/tex] (alternate interior angles)

From the given options, we can eliminate [tex]\( m\angle2 = 31\° \)[/tex] and [tex]\( m\angle2 = 50\° \)[/tex] because these options would imply that [tex]\( m\angle6 \) and \( m\angle7 \)[/tex] are also [tex]\( 31\° \) and \( 50\° \)[/tex], respectively. This would mean that the sum of the angles in the triangle formed by the transversal and line c would be less than [tex]\( 180\° \)[/tex], which is impossible.

Next, we consider [tex]\( m\angle2 = 120\° \)[/tex]. If this were true, then [tex]\( m\angle7 \)[/tex] would also be [tex]\( 120\° \)[/tex]. However, this would imply that the sum of the angles in the triangle formed by the transversal and line c would be [tex]\( 120\° + 60\° \)[/tex] (since [tex]\( m\angle6 \) and \( m\angle8 \)[/tex] would be supplementary, adding up to [tex]\( 180\° \)[/tex]), which again is impossible because the sum of angles in any triangle is [tex]\( 180\° \).[/tex]

Finally, we consider [tex]\( m\angle2 = 130\° \)[/tex]. This option is possible because if [tex]\( m\angle2 = 130\° \)[/tex], then [tex]\( m\angle7 \)[/tex] would also be [tex]\( 130\° \)[/tex]. The remaining angle in the triangle formed by the transversal and line c (which is [tex]\( m\angle6 \) or \( m\angle8 \)[/tex]) would be [tex]\( 180\° - 130\° = 50\° \)[/tex]. This satisfies the triangle angle sum property, as [tex]\( 130\° + 50\° = 180\° \)[/tex].

Therefore, the correct measure of angle 2 is [tex]\( m\angle2 = 130\° \)[/tex].
