[header] How to create a christmas tree forest [title] Consider the type of tree you want to plant. [step] There are a wide variety of christmas trees and include fir, pine, spruce, cypress, and cedar. These trees thrive in different climates and look different from one another. <sep> (A) It is important to research the tree before setting up your tree to try it out to make sure you can write the tree's growing season so that you can get the most supplies you need. If you're just interested in having a tree stand out, then make sure to check for the following : [substeps] Spruce trees. (B) [substeps] Trees green may be used in a mix of green and evergreen. Greens, such as pintos and olive oil, may be more delicate than these. (C) Where the trees grow together is up to you. [substeps] Spruce trees light up the night for hours in the morning and drown out the morning sunrise between afternoons. (D) Think about where your tree forest will be located and choose a tree that can thrive in that climate. [substeps] Balsam firs are a popular christmas tree species that grow in the northern united states and canada, in hardiness zones 3-5 or states like minnesota, north dakota, and montana.

Now, solve this instance: [header] How to calculate man hours [title] Divide your project into components. [step] The first part of calculating the man-hours you will need to do a job is to split up the project into smaller components. Then estimate the amount of hours needed to complete each component. <sep> (A) This formula allows you to divide the time needed to come up with the total number of hours needed for your project. [substeps] Example: if you divide the amount of hours needed to complete the project by 11, then you would get 11 hours of man hours. (B) [substeps] Once you've determined the total number of hours you will need to complete the task you'll be doing, add those hours to that number. For example, if you will be working on a project that's 50 pages long, subtract 50 for 80 minutes. (C) These components should be designated according to the type of labor involved. If you are building an apartment complex, you will need excavation, construction, electrical, plumbing, and so on. (D) Once all components have been completed, calculate the man hours you will need to do, after which time you will divide the total amount of time that you should take to complete each component. [substeps] Schedule an appointment if you need to discuss the work in detail.
