Derrick has 72 inches of ribbon to make bows. He uses all of his ribbon to make 9 bows of equal length l . How many inches of ribbon does each bow use? Write an equation to model the situation. Then solve the problem.

Without the markup percentage or discount percentage, it is impossible to calculate the actual cost price the store paid for the trumpet. One needs this additional information to provide a precise answer.

The question "if the price tag on a trumpet says $104, how much did the store pay for it" cannot be answered with the information provided. To calculate how much the store paid for the trumpet, we need additional details such as the markup percentage or the discount percentage. Retail stores typically apply a markup to the cost of the goods they purchase from suppliers to cover their operating expenses and make a profit.

Let's assume the markup percentage is known. For example, if a store generally marks up items by 50%, and the selling price of the trumpet is $104, we can calculate the store's cost using the formula: Cost Price = Selling Price / (1 + Markup Percentage). So the cost would be $104 / (1 + 0.50), which is $69.33.

Without the markup or discount information, it is impossible to determine the exact cost price that the store paid for the trumpet.

Answer:

Step-by-step explanation:

The polynomial f(x)=x^4+2x^3−27x−54 has x+2 as a factor. The complete factorization of f(x) after polynomial division and analysis is (x + 2)(x^2 - 3x + 9)(x + 3).

To show that x+2 is a factor of f(x)=x^4+2x^3−27x−54, we need to use the Factor theorem which states that if a polynomial f(x) has a factor of the form x - k, then f(k) = 0.

So, if x + 2 is a factor of the function, then f(-2) should equal 0. Let's apply this to our function:

f(-2) = (-2)^4 + 2(-2)^3 - 27(-2) -54 = 16 -16+54 -54 = 0. So x+2 is indeed a factor.

To factor f(x) completely, we will perform polynomial division of f(x) by the factor (x+2) which will give us g(x) = x^3 - 27. This can be further factored to x^3 - 3^3 which is a difference of cubes. Consequently, the complete factorization of f(x) would be:

f(x) = (x + 2)(x^2 - 3x + 9)(x + 3).

Perimeter of a rectangle = 6x + 8

Solution:

Given area of a rectangle = [tex]2x^2+7x+3[/tex]

Let us first factor the given polynomial.

[tex]2x^2+7x+3=2x^2+x+6x+3[/tex]

                    [tex]=(2x^2+x)+(6x+3)[/tex]

Taking out common terms in the above expression

                    [tex]=x(2x+1)+3(2x+1)[/tex]

Taking out common term [tex]2x+1[/tex] in the above expression

                    [tex]=(2x+1)(x+3)[/tex]

[tex]2x^2+7x+3=(2x+1)(x+3)[/tex]

Area of a rectangle = l × b

Therefore, [tex]l=2x+1[/tex] and [tex]b=x+3[/tex]

Perimeter of a rectangle = 2(l + b)

                                         [tex]=2[(2x+1)+(x+3)][/tex]

                                         [tex]=2(2x+1+x+3)[/tex]

                                         [tex]=2(3x+4)[/tex]

                                         [tex]=6x+8[/tex]

The answer is same if you take l = x + 3 and b = 2x + 1.

Hence, perimeter of a rectangle = 6x + 8.

Answer:

Total cost of the meal is $ 27.32.

Step-by-step explanation:

Given:

Cost of the meal = $25.30

Tax levied on it = 8%

We have to find the total cost.

Total cost of the meal = Summation of cost of the meal and levied tax.

So,

We have to calculate the tax.

⇒ [tex]8\%\ of\ \$25.30[/tex]

⇒ [tex]\frac{8}{100}\times \$25.30[/tex]

⇒ [tex]0.08\times \$25.30[/tex]

⇒ [tex]\$2.024[/tex]

Tax imposed = [tex]\$2.024[/tex]

Now,

Total cost of the meal =Tax + Meal cost

⇒ [tex]\$(2.024+25.30)[/tex]

⇒ [tex]\$27.324[/tex]

Total cost of the meal is $ 27.32.

Answer:

[tex]y=\frac{1}{2}x-3[/tex]

Step-by-step explanation:

step 1

Find the slope of AB

we know that

The formula to calculate the slope between two points is equal to

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

we have

A(5,-1), B(9, -9)

substitute the values

[tex]m=\frac{-9+1}{9-5}[/tex]

[tex]m=\frac{-8}{4}[/tex]

[tex]m=-2[/tex]

step 2

Find the slope of the line that is perpendicular to AB

we know that

If two lines are perpendicular, their their slopes are opposite reciprocal (the product of their slopes is equal to -1)

we have

[tex]m_A_B=-2[/tex]

therefore

The slope of the perpendicular line is

[tex]m=\frac{1}{2}[/tex]

step 3

Find the equation of the line in point slope form

[tex]y-y1=m(x-x1)[/tex]

we have

[tex]m=\frac{1}{2}[/tex]

[tex]C(4,-1)[/tex]

substitute

[tex]y+1=\frac{1}{2}(x-4)[/tex]

step 4

Convert to slope intercept form

Isolate the variable y

[tex]y+1=\frac{1}{2}x-2\\\\y=\frac{1}{2}x-2-1\\\\y=\frac{1}{2}x-3[/tex]

Answer:

Approximately 43 feet of minimum cable is needed.

Step-by-step explanation:

This problem can be solved using Trigonometry and Pythagorean theorem. Pythagorean theorem applies on right-triangles (which are known to have one 90° angle). The theorem states that the square of the Hypotenuse is obtained by the squared sum of the other two sides of the triangle (i.e the two sides forming the 90° angle - with the hypotenuse side being across it as:

[tex]h^2=a^2+b^2[/tex]           Eqn. (1)

where

[tex]h[/tex] is the hypotenuse

[tex]a[/tex] is a side

[tex]b[/tex] is a side

Now in this case, the utility pole must be perpendicular to the ground and the anchor being parallel to the ground, and a 90° angle formed between them. Conclusively the cable length will be represented by the hypotenuse in a right triangle. So here we have [tex]a=40ft[/tex] and [tex]b=15ft[/tex]. Plugging in Eqn.(1) and solving for [tex]h[/tex] we have:

[tex]h^2=40^2+15^2\\h=\sqrt{40^2+15^2} \\h=\sqrt{1600+225}\\ h=\sqrt{1825}\\ h=5\sqrt{73}\\ h=42.72ft[/tex]

So we conclude that the minimum length of cable needed by Lamont is

≈43 feet (rounded up).

Answer:

Center = (0, -4)

Radius = [tex]\sqrt{7}[/tex] units

Step-by-step explanation:

We are given;

The equation of a circle;

[tex]x^2+y^2+4y=3[/tex]

We are required to determine the radius and the center of the circle;

To do this we are going to use completing square method;

[tex]x^2+y^2+4y=3[/tex]

Since we don't have the x term then;

[tex]x^2+ox+y^2+4y=3[/tex]

We add the square of half the coefficients of x and y on both sides of the equation;

That is;

[tex]x^2+0x+(0^2)+y^2+4y + (2^2)=3+0+(2^2)[/tex]

We get;

[tex]x^2+0x+(0^2)+y^2+4y + (2^2)=7[/tex]

Taking the squares;

[tex](x+0)^2+(y+4)^2=7[/tex]

But we know when the equation of a circle is written in the form of;

[tex](x-a)^2+(y-b)^2=r^2[/tex], where (a,b) is the center and r is the radius of the circle.

Thus, in this case;

[tex](x+0)^2+(y+4)^2=7[/tex]

Center = (0, -4)

Radius = [tex]\sqrt{7}[/tex] units

Step-by-step explanation:

1) Original equation: 3(2) - 18x +225 = 6

2) Simplify: 6 - 18x + 225 = 6

3) Move 18x over to the right: 6 + 225 = 6 + 18x

4) Move the 6 on the right over to the left: 225 = 18x

5) Divide both sides by 18 to isolate x: 225/18, 18x/18

6) x = 12.5

Answer:

The Correct option is C ) 25

Therefore the value of x is 25 when y =40.

Step-by-step explanation:

Given:

Variable 'y' is directly proportional to the variable 'x'.

[tex]\therefore y=kx[/tex]     ......Direct Variation

Where,

k = Constant of proportionality

To Find:

value of x = ? when y = 40

Solution:

First we need to find Constant of proportionality

When x = 20 and y = 32

Substituting the values we get

[tex]32=k\times 20\\k=\dfrac{32}{20}=1.6\\\\k=1.6[/tex]

Now when k =1.6 , y = 40 then x will be

[tex]40=1.6\times x\\\\x=\dfrac{40}{1.6}=25\\\\x=25[/tex]

Therefore the value of x is 25 when y =40.

Final answer:

The value of x when y is 40 is C) 25.

Explanation:

The variable y is directly proportional to the variable x.

This means that as x increases or decreases, y does so at a constant rate.

This relationship can be written as y = kx, where k is the constant of proportionality.

To find k, we use the information that y = 32 when x = 20, leading to the equation 32 = k * 20.

Solving this gives us k = 32 / 20 or k = 1.6.

With the constant k known, we can find the value of x when y = 40 by setting up the equation 40 = 1.6x.

Dividing both sides by 1.6 gives us x = 40 / 1.6, which results in x = 25.

Therefore, the correct answer is C) 25.

The similarity statement: FGHI ~ BCDE

Similarity ratio: 5:1

Step-by-step explanation:

The similarity statement is quite obvious, as there are only two rectangles shown, and the other one is "BCDE".

The similarity ratio is 5:1 because everything in the 1st (FGHI) rectangle is multiplied 5 times the values in the 2nd (BCDE) rectangle.

Answer: 4/3

Explanation: To write the fraction 8/6 in lowest terms, we divide the numerator and the denominator by the greatest common factor of 8 and 6.

Since the factor of 8 are 1, 2, 4, and 8 and the factors of 6 are 1, 2, 3, and 6, the greatest common factor of 8 and 6 is 3 so we divide the numerator and the denominator of 8/6 by 2 and we get 4/3.

So 8/6 can be simplified to 4/3.

4/3 can also be changed to the mixed number 1 and 1/3.

Twenty nine and one third is your answer.

Final answer:

The expression 1/3 (4+18) 4 evaluates to approximately 29.333 following the order of operations; first the addition inside the parentheses, then multiplication by 1/3, and lastly by 4.

Explanation:

When evaluating the expression 1/3 (4+18) 4, it's essential to follow the orders of operation, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication, and Division (from left to right), Addition and Subtraction (from left to right)). Let's break down the problem step by step:

Now, perform the multiplication: 22 * 4 = 88. Since we are multiplying by a division by 3 (22/3), it is the same as dividing 88 by 3, which gives us the final answer: 88 divided by 3 equals 29 with a remainder of 1, or as a decimal, approximately 29.333.

The correct answer to the expression 1/3 (4+18) 4 is therefore approximately 29.333. It is crucial to always follow the order of operations in any math problem to get the correct result.

Answer:

11.55

Step-by-step explanation:

An equilateral triangle is one which all it sides are equal.

10cm altitude means the height is 10cm.

Using Pythagoras theorem,

x² = 10² + (x/2)²

Assume that the side of the triangle is xcm

x² - x²/4 = 100

3x²/4 = 100

x = √(400/3)

x = 11.55cm

Since 9 is 3², each digit in base nine takes two digits in base 3.

Answer:

A) -2/3

Step-by-step explanation:

We are given the equation;

5 - 2m - 3m² = 0

We are required to get the sum of the roots of the equation;

Rearranging the equation;

3m² + 2m - 5 = 0

product = -15 m²

sum = 2 m

Terms = 5m and -3m

Therefore;

3m² + 5m - 3m - 5 = 0

Factorizing by pairing

m(3m + 5) - 1 (3m + 5) = 0

Thus;

(m - 1) (3m + 5) = 0

This means;

m - 1 = 0 or 3m + 5 =0

Hence; the roots of the equation are;

m = 1 or m = -5/3

Thus, the sum of the roots is;

= 1 + -5/3

= -2/3

Hence, the sum of the roots of the equation is -2/3
