suppose that 11 inches of wire cost 66 cents at the same rate how much (in cents) will 28 inches of wire cost ​

1÷3=13.

Step-by-step explanation:

To find the reciprocal of any number simply take 1 and divide it by that number, so the reciprocal of 3 is 1÷3=1/3. We can check that this is the multiplicative inverse of 3 by multiplying those two numbers together and seeing if we get 1: so 3×1/3=3×1/3=1. Where it says =3 you put a line through that 3.

Answer:

a) 2x² + 14x + 24 = 0

Step-by-step explanation:

a)

2x² + 14x + 24 = 0

2(x + 4) (x + 3) = 0

x = -4 or x = -3

b)

x² - 6x + 5 = 0

(x - 1)(x - 5) = 0

x = 1 or x = 5

c)

3x² + 30x + 48 = 0

3 (x + 8) (x + 2) = 0

x = -8 or x = -2

d)

-3x² - 12x + 15 = 0

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

x = -5 or x = 1

Final answer:

The equation which yields the solutions x=-3 and x=-4 is a. 2x² + 14x + 24 = 0.

Explanation:

To find which equation yields the solutions x=-3 and x=-4, we need to determine which equation, when factored, gives these roots. If an equation has roots x = -3 and x = -4, then it can be written in factorized form as:

(x + 3)(x + 4) = 0

Expanding this, we get:

x² + 4x + 3x + 12 = 0

x² + 7x + 12 = 0

Looking at the given options, we notice that none of them exactly match this equation. However, if we multiply our equation by 2, we get:

2x² + 14x + 24 = 0

This matches option (a). Therefore, the correct equation is:

2x² + 14x + 24 = 0

Final answer:

To rewrite the radical expression 5 square root of x to the 7th power with rational exponents, express it as 5x7/2.

Explanation:

To rewrite the radical expression as an expression with rational exponents, we can use the property that the square root is equivalent to raising to the power of 1/2. Thus, 5√x7 = 5x7/2.

The answer is B. If angle b is congruent to angle c, then you would write the problem as 12x + 4= 14x-2. X=3. You can check by substituting three for x.

Final answer:

To find the value of x in the isosceles triangle ABC with given angle expressions, we set the expressions for angles B and C equal, leading to a simple equation that yields x = 3.

Explanation:

The question involves finding the value of x in an isosceles triangle where the angles at base B and C are given as algebraic expressions in terms of x. Since triangle ABC is isosceles with angles at B and C being equal, we can set the expressions for m∆B and m∆C equal to each other and solve for x.

Let's set up the equation using the fact that m∆B = m∆C since ∆ ABC is isosceles:

(12x + 4)° = (14x - 2)°

We can then solve for x:

Subtract 12x from both sides: 4° = 2x - 2°

Add 2° to both sides: 6° = 2x

Divide by 2 to solve for x: x = 3

The value of x is therefore 3, which corresponds to answer choice B.

312 m

Step-by-step explanation:

Write and solve an equation of ratios:

 7       273 m

----- = ------------

 8            x

Then 7x = 8(273 m) = 2184 m

and x = 2184 m / 7 = 312 m

The second length in the given ratio of 7:8, when the first length is 273m, is calculated to be 312m.

The given question is about ratios, particularly the ratio between two lengths, where one of them is given as 273 meters and the ratio is 7:8. The ratio tells us that for every 7 units of the first length, there are 8 units of the second length. To calculate the second length, first find the value of one ratio unit by dividing the given length by its ratio (273m / 7), then multiply your result by 8.

Steps:
1. 273m / 7 = 39m (This is one ratio unit)
2. 39m * 8 = 312m (This is the second length).

Therefore, the length of the second line is 312 m.

Answer:

Step-by-step explanation:

the equation of the graph  : y = sin(x + 90°)

because when :  x= 0 :  y = sin90° = 1

Answer:

Option A y = sin ( x + 90 )

Step-by-step explanation:

The given graph is the graph of cosine which should be in the form of

y = a cos ( bx + c ) + d

here a = amplitude = [tex]\frac{1-(-1)}{2}[/tex] = [tex]\frac{2}{2}[/tex] = 1

Since period of the wave is 2x or 360°.

we know, period = [tex]\frac{2\pi }{b}[/tex]

                          [tex]b=\frac{2\pi }{2\pi }[/tex] = 1

Now equation becomes,

y = cos ( x + c ) + d

In this graph there is no horizontal or vertical shift

c = 0 and d = 0

so equation will be  y = cos (x)

as we know              y = cos (x) = sin ( 90 + x )

Therefore, Option A y = sin ( x + 90 ) is the answer.

Answer:

The Median is 9

Step-by-step explanation:

To calculate the median of a data set the first step is to sort the data from least to greatest

4,11,6,9,23,34,6,9

4, 6, 6, 9, 9, 11, 23, 34

The second step is to locate the central value. If the total amount of data is an even number then locate the two central data and the median will be the average of both. In this case we have 8 data. Then the central values will be the data number 4 and the data number 5

4, 6, 6,   [9, 9],   11, 23, 34

Answer:

your answer would be 9 printers

The answer is:

There are a total of 9 black and white printers

To solve the problem, first, we need to calculate how many color printers represents two-fifths of the total printers, then, calculate the number of black and white printers using the total number of printers and the number of color printers.

Calculating how many color printers does the departament have:

[tex]ColorPrinters=TotalPrinters*\frac{2}{5} \\\\ColorPrinters=15*\frac{2}{5}\\\\ColorPrinters=\frac{30}{5}=6[/tex]

Therefore, we have that there are 6 color printers.

Now, calculating the number of black and white printers, we have:

[tex]TotalPrinters=ColorPrinters+BlackAndWhitePrinters\\\\BlackAndWhitePrinters=TotalPrinters-ColorPrinters\\\\BlackAndWhitePrinters=15printers-6printers=9printers[/tex]

Hence, we have that there are a total of 9 black and white printers.

The angle between the longest side and the diagonal of the rectangle is approximately 30 degrees.

Trigonometric functions are defined as the functions which show the relationship between the angle and sides of a right-angled triangle.

To solve this problem, we can use the Pythagorean theorem and trigonometric functions.

First, we can find the length of the diagonal of the rectangle using the Pythagorean theorem:

diagonal² = longest side² + shortest side²

diagonal² = 1000² + 577²

diagonal = √(1000² + 577²)

diagonal = 1162.46 mm (rounded to two decimal places)

Next, we can find the angle between the longest side and the diagonal using the inverse tangent function:

tan(θ) = opposite / adjacent

tan(θ) = 577 / 1000

θ= arctan(577 / 1000)

θ= 29.98

θ ≈ 30 degrees

Therefore, the angle between the longest side and the diagonal of the rectangle is approximately 30 degrees.

Step-by-step explanation:

Tara's unit rate of reading is 1.4 pages per minute, which means an equivalent rate is 2.8 pages per 2 minutes.

The question involves calculating an equivalent rate to Tara's unit rate of reading pages per minute. To find Tara's unit rate, we first need to determine how many pages she reads in one minute. Since Tara reads 3 1/2 pages in 2 1/2 minutes, we divide the number of pages by the number of minutes to find the unit rate:

To find an equivalent rate, we can multiply both the numerator and the denominator by the same number to get a rate with different terms but the same value. For example, multiplying by 2 would give us:

Therefore, an equivalent rate to Tara's reading speed would be 2.8 pages per 2 minutes.

To find the relationship between two quantities, x and y, in a table, analyze patterns in the changes of the values, determine if the relationship is linear or nonlinear, and then use the identified relationship to calculate missing values. A computer can be useful for plotting data and visualizing the relationship.

To find the relationship between two quantities, x and y, in a table, first, you need to look for a pattern in the way the numbers change. If y changes by a consistent amount when x changes by a set amount, the relationship is likely linear. If the rate of change itself changes, the relationship may be nonlinear. To determine the relationship:

To fill in missing values:

When calculating these relationships, plotting data using computers can be helpful, especially for identifying linear or nonlinear relationships and for regression analysis in more complex datasets.

we know line P is y = 3x.

parallel lines have the same slope but different y-intercept, where the graph touches the y-axis.  So then parallel lines is the same equation but shifted some either upwards or downwards or sideways.

so then line Q must be the same as P, y = 3x + "some change", well, we notice that the perpendicular distance from each other is 3 units, so then, the y-intercept of P is at (0, 0), thus the y-intercept of Q must be 3 units downwards, at (0, -3), since Q is shifted downwards, thus Q is y = 3x - 3.
