A book sold 36,600 copies in its first month of release. Suppose this represents 7.1% of the number of copies sold to date. How many copies have been sold to date?

Answers

Answer:

515,493 copies sold

Step-by-step explanation:

Since this is a ratio problem and we have three values and one variable that we need to find (copies sold to date) then we can use the Rule of three to solve this problem. We simply need to multiply the diagonal values and divide by the third value to get the variable. This can be seen below...

36,600 copies   <=====>   7.1%

    x  copies   <========>  100%

(36,600 * 100) / 7.1 = 515,492.96  

Since the number of books cannot be a decimal we must round up to the nearest book sold, which would mean that the number of copies sold to date is 515,493 copies sold

A rectangle has an area of . Use factoring to find possible dimensions of the rectangle. Explain why you can use factoring to find the answer.

Answers

Answer:

The answer is below

Step-by-step explanation:

A rectangle has an area of x² + 7x + 12. Use factoring to find possible dimensions of the rectangle. Explain why you can use factoring to find the answer.

Solution:

A rectangle is a quadrilateral (ha four sides and four angles) in which opposite sides are parallel and equal to each other. All the four angles in a rectangle are 90° each.

The area of a rectangle is given by:

Area = length * width

Hence the area is the product of two sides.

Given that:

Area = x² + 7x + 12

Factoring to find both the length and width of the rectangle:

Area = x² + 7x + 12

Area = x² + 4x + 3x + 12

Area = x(x + 4) + 3(x + 4)

Area = (x + 4)(x + 3)

After factoring we can see that the area is the product of (x + 4) and (x + 3). Hence x + 4 is the length and x + 3 is the width.

The length of a side of a regular pentagon is f + 12.
Write the perimeter of the figure in one simplified
expression.

Answers

Answer:

5f+60

Step-by-step explanation:

Answer:

P = 5f + 60

Step-by-step explanation:

The Perimeter of a Regular Shape

A regular shape has sides that are all the same length as each other and angles that are all congruent to each other. The perimeter is the total distance around the outside of a shape.

To find the perimeter of a regular shape, we simply multiply one side length by the number of sides of the shape.

It's given the length of a side of a regular pentagon (n=5) as L=f+12.

The perimeter of the pentagon is 5 times f+12:

P = 5(f + 12)

Operating:

P = 5f + 60

If point P is Four-sevenths of the distance from M to N, what ratio does the point P partition the directed line segment from M to N into? 4:1 4:3 4:7 4:10

Answers

Answer: Point P partitioned the line segment MN into 4:3.

Step-by-step explanation:

Point P is [tex]\dfrac47[/tex]of the distance from M to N.

Let the distance between M to N =x.

[tex]MP=\dfrac47x[/tex]

Point P partition the directed line segment from M to N .

MN = MP+PN

[tex]\Rightarrow\ x=\dfrac47 x+PN\\\\\Rightarrow\ PN =x-\dfrac47 x\\\\\Rightarrow\ PN=\dfrac37 x[/tex]

Ratio of MP to PN = [tex]=\dfrac{\dfrac{4}{7}x}{\dfrac{3}{7}x}=\dfrac43[/tex]

Point P partitioned the line segment MN into 4:3.

XYZ will be translated so that the coordinates of X, are (5,11) . What will the coordinates of Z,?

Answers

Answer:

Z'(6, 7)

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.

Translation is the movement of a point up, down, right and left. If a point A(x, y) is translated a units right and b units up, the new point would ne at A'(x + a, y + b). Also, If a point A(x, y) is translated a units left and b units down, the new point would ne at A'(x - a, y - b).

Given that the coordinates of triangle XYZ is at X(7, 11), Y(10, 14) and Z(8, 7).

XYZ will be translated so that the coordinates of X, are (5,11), therefore a translation of 2 units left is done (x - 2, y). The new coordinates are:

X'(5, 11), Y'(8, 14) and Z'(6, 7)

Step-by-step explanation:

The number is [tex]\dfrac{3}{5}=0.6[/tex]

The choices are

[tex]\dfrac{3}{5}\times \dfrac{3}{7}=\dfrac{9}{35}=0.257[/tex]

[tex]\dfrac{3}{5}\times 0=0[/tex]

[tex]\dfrac{3}{5}\times \dfrac{5}{3}=1[/tex]

[tex]\dfrac{3}{5}\times 1=\dfrac{3}{5}[/tex]

So, we have to check which product is greater than 0.6.

Only one of the products is greater than 0.6 which is [tex]\dfrac{3}{5}\times \dfrac{5}{3}=1[/tex].

how would the fraction 5÷1-√(3 be rewritten if it's denominator is rationalized using difference of squares

Answers

Answer:

-5(1 + √3)/2

Step-by-step explanation:

To rationalize 5÷1-√3, we multiply both the numerator and the denominator by the conjugate of 1 - √3 = 1 + √3.

So 5 ÷ (1 - √3) = 5/(1 - √3), we multiply by the conjugate of the denominator, we have

5/(1 - √3) × (1 + √3)/(1 + √3) = 5(1 + √3)/[(1 - √3) × (1 + √3)]

=  5(1 + √3)/(1² - (√3)²)

=  5(1 + √3)/(1 - 3)

= 5(1 + √3)/-2

= -5(1 + √3)/2

The speech was part of the March on Washington for Jobs and Freedom. The speech not only helped to galvanize the already growing civil rights movement across the country at the time, it also became one of the most influential and inspirational pieces of rhetoric in American history.Remarkably, midway through his delivery, King suspended his pre-scripted text and began to improvise; what resulted was the speechs most recognizable section, the passage in which the words I have a dream are passionately repeated. Indeed, Kings background as a Baptist preacher in the South instilled in him a talent for improvisation as a speaker and the skill to frame the urgency of the moment.Based on the background knowledge of "Jim Crow" laws, historically was what going on around the 1960s when Dr. Martin Luther King was delivering his speech "I Have a Dream?"
