Let's call the time it takes for excavator A to dig the pit "a" and the time it takes for excavator B to dig the pit "b". We know that a + b = 3 (since together they take three days) and a = b + 8 (since excavator A takes 8 days longer than excavator B). We can solve these equations to find that b = 5 and a = 13. Therefore, excavator A alone needs 13 days to dig the construction pit. **

An excavator is a heavy construction machine used for digging and moving large amounts of earth, debris, or other materials. It typically consists of a boom, bucket, cab, and tracks or wheels for mobility. Excavators are commonly used in construction, mining, and landscaping projects to dig trenches, foundations, and holes, as well as to move materials such as soil, rocks, and debris. They are versatile machines that can be equipped with various attachments to perform different tasks. **

Math-excavator homework is a type of assignment that requires students to dig deeper into mathematical concepts and problem-solving skills. It often involves solving complex problems, analyzing patterns, and applying various mathematical techniques to arrive at a solution. This type of homework encourages students to think critically and develop a deeper understanding of mathematical concepts. It also helps them to develop their problem-solving skills and gain a greater appreciation for the beauty and complexity of mathematics. **

An excavator task refers to the specific job or activity that an excavator is used to perform. This can include tasks such as digging trenches, removing debris, lifting heavy objects, and clearing land. Excavators are versatile machines that can be used for a wide range of tasks in construction, landscaping, and other industries. The specific task will depend on the needs of the project and the capabilities of the excavator. **

An excavator hour refers to the amount of time an excavator machine has been in operation or used for a specific task. It is a unit of measurement used to track the productivity and efficiency of the excavator. By monitoring the number of excavator hours, operators and project managers can better estimate costs, schedule maintenance, and track progress on a construction site. **

Chrome needs storage access to download files because it needs to save the downloaded files to the device's storage. Without storage access, Chrome would not be able to save the downloaded files to the device, making the download process impossible. Additionally, storage access allows Chrome to manage and organize the downloaded files within the device's storage, making it easier for users to access and use the downloaded content. **

Stock Android can be downloaded by installing a custom ROM that is based on the official Android Open Source Project (AOSP). This can be done by unlocking the bootloader of the device, installing a custom recovery, and then flashing the custom ROM. It's important to note that this process can vary depending on the device, and it may void the warranty. Additionally, it's crucial to ensure that the custom ROM is compatible with the specific device model to avoid any potential issues. **
