## To solve the problem and write the equation, you need to understand the given information and what the problem is asking for. Let's break it down step by step:

(1) Science:

The problem states that Jose rode his trail bike for 10 miles, and two-thirds of the distance was over a mountain trail. The task is to determine the length of the mountain trail.

To find the length of the mountain trail, you can set up an equation using the given information. Let's say "x" represents the length of the mountain trail in miles.

Since two-thirds of the 10-mile distance is the mountain trail, you can express this as a fraction:

(2/3) * 10 = x

This equation shows that two-thirds of the total distance, 10 miles, is equal to the length of the mountain trail, represented by "x". By solving this equation, you will find the value of "x" and obtain the length of the mountain trail.

(2) Statistics:

The problem states that Joel had 4 hits in 13 times at bat, and the task is to find Joel's batting average as a decimal value rounded to three decimal places.

To find the batting average, you need to divide the number of hits by the number of times at bat. In this case, Joel had 4 hits out of 13 times at bat.

To write this as an equation, let "BA" represent Joel's batting average:

BA = number of hits / number of times at bat

BA = 4/13

By dividing 4 by 13, you will get the decimal equivalent of Joel's batting average. Remember to round the result to three decimal places.

For the last question about the volume and surface area of the box that holds 24 cans, please specify the dimensions of the cans (diameter, height).
