The number of sports books is 13 books.
<h3>What is an equation?</h3>
A mathematical equation is the representation of a problem by the use of variables. Often times, an equation is formed from the factors that are in a problem.
We have to represented each of the books read with an algebraic term;
Let the number of mystery books be y
Let the number of sports books be x
Total number of books = 23
We know that;
x + y = 23
but y = 10
x = 23 - 10
x = 13 books

graph each side of the equation. the solution si the x-value of the point of intersection.
The empirical rule tells you 68% of normally-distributed observations are within 1 standard deviation of the mean.
_____
This is a number you may want to memorize, along with the numbers for 2 (95%) and 3 (99.7%) standard deviations.
For 12 Pounds (= 12 * 16 = 192 Ounce), it costs = 18.75
So, for 1 Ounce, it would be: 18.75 / 192 = 0.097
In short, Your Answer would be: $0.097

Given:
Rectangle: 320 x 190
triangle: base: 305
I'm assuming that the unit measure is in miles.
I found a map of Nevada and I figured that the length of the rectangle is serving as the height of the triangle.
Area of the rectangle = Length * width
A = 320 mi x 190 mi
A = 60,800 sq. mi.
Area of a triangle = (height * base) / 2
A = (320 mi x 305 mi) / 2
A = 97,600 sq. mi / 2
A = 48,800 sq. mi.
Total Area = 60,800 + 48,800 = 109,600 square miles.
