3.5 inches

Step-by-step explanation:

Given :

A photography book has 60 two-sided pages of pictures.

Thickness of each page is $\frac{1}{40}$

Each two-sided page is preceded by a protective 1/80 inch thick piece of paper.

Each side of the book is bound by a 1/4 inch cover.

To Find: What is the total thickness of the book?

Solution :

Since each two sided page is preceded by a protective 1/80 inch thick piece of paper.

So, both sided preceded by a protective thick piece = $2*\frac{1}{80}$

= $\frac{1}{40}$

And Thickness of each paper $\frac{1}{40}$

So, total thickness of paper : $\frac{1}{40}+\frac{1}{40}$

$\frac{2}{40}$

Since there are 60 pages.

So, thickness of 60 pages = $60*\frac{2}{40}$

= 3 inches

Now each side of the book is bound by a 1/4 inch cover

So, thickness of cover of both side = $2*\frac{1}{4}$

= $\frac{1}{2}$

Now total thickness of book = thickness of 60 pages + thickness of both side covers

= $3+\frac{1}{2}$

= $\frac{7}{2}$

Thus the thickness of the book is 7/2 inches .

Hence the total thickness of book is 3.5 inches

Answer from: Quest

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

Evaluate 8x2 + 9x − 1 2x3 + 3x2 − 2x dx. solution since the degree of the numerator is less than the degree of the denominator, we don't need to divide. we factor the denominator as 2x3 + 3x2 − 2x = x(2x2 + 3x − 2) = x(2x − 1)(x + 2). since the denominator has three distinct linear factors, the partial fraction decomposition of the integrand has the form† 8x2 + 9x − 1 x(2x − 1)(x + 2) = correct: your answer is correct. to determine the values of a, b, and c, we multiply both sides of this equation by the product of the denominators, x(2x − 1)(x + 2), obtaining 8x2 + 9x − 1 = a correct: your answer is correct. (x + 2) + bx(x + 2) + cx(2x − 1).
