Answer:
31,692 inches
Step-by-step explanation:
The length that Marc travelled with his bike can be calculated by the product between the number of rotations of the tire and the circunference of the tire.
So, calculating the circunference of the tire, we have:
C = pi*diameter = pi*26 = 81.68 inches
If in each rotation of the tire, the length travelled is 81.68, the total length travelled is:
Length = number of rotations * C = 388 * 81.68 = 31,691.84 inches
Rounding to the nearest inch, we have Length = 31,692 inches
A is the correct answer.......
Here is the work shown:
x^2-x-20
A is the correct answer because when using the distributive property it is the only example that results in x^2-x-20.
(x+4)(x-5)
x*x=x^2, x*-5=-5x, 4*x=4x, 4*-5=-20. Now combine all alike terms for your final answer. x^2-x-20..

Answer:
129 physics textbooks, 183 biology textbooks
Step-by-step explanation:
Let x be the number of biology textbooks and x-54 the numbers of physics textbooks.
So:
x+(x-54)=312
2x-54=312
2x=366
x=183
So 129 physics textbooks and 183 biology textbooks were sold.
To find probability you have to add the samples that are included. In this situation, you add 240+210. Then you get 450. Then you divide heads by 450 to get the probability.
The probability is 240/450, which is 53%
In fractions it is 53 1/3.
