If Sally has 14 cookies and shares 5 with her friend, eats two, and then bakes 9 more, how many cookies does she have at the end of the day?

Let's start by writing out what this question is asking. Sally has 14 cookies She shares 5 (this means she gives them away and subtracts them) Eats two (again Sally looses two more and subtracts them) And bakes 9 more (she adds 9 more) So we come up with an equation that looks like this: 14-5-2+9= And we can break it down like this: 14-5=9 (gives these to a friend) 9-2=7 (eats two cookies) 7+9=16 (bakes 9 more) So we now know that Sally has 16 cookies at the end of the day!

What is the purpose of studying International Relations?

International relations is important to study because it helps political scientists understand how state and non-state international actors interact with each other. These actors can include international organizations such as the United Nations, corporations, and foreign governments. Studying and understanding the patterns and theories can help solve worldwide issues such as war or poverty, help to create cooperation among these actors, and resolve issues that arise in the future. With this knowledge, professionals in the field can direct laws, policies, diplomacy, and security and be more effective and efficient.

How do you use the lasso tool in photoshop?

Here is a step by step on how to use the lasso tool to do a basic selection of an object: 1. Select the lasso tool, which will typically be on the left side of the screen. (it looks exactly like a cowboy's lasso!) 2. When you left-click on it, it should select the normal lasso tool. If it is not set to this, you can right-click the small arrow in the bottom corner and a menu should appear, then click the lasso tool. 3. Using your mouse or finger (depending on what kind of device you are on) trace around the area you would like to select. 4. Make sure to connect the ends to each other, otherwise, it will auto-connect in a straight line! 5. Once you've selected your object a "dancing" line should appear around your object, this is how you know it is selected. 6. From here you can copy and paste it into another file, cut it and move it, delete it from the photo, or refine the edge further. How to refine the edge further fr a more exact selection: 1. At the bottom of the screen or on the right side there will be an option stating refine edge. 2. Click on this option and a new menu should pop up. 3. In this menu you will have an option to use the edge detection radius here is what it means: - Edge detection radius: this will take the edge of your selection and pull it closer to the object. (ex: if you are selecting a person who has hair, this option will pull the edge of the selection around each hair instead of it being a "blob" shape) More pixels mean more concentrated and defined selection. There are many other ways to refine the edge, if you are interested in learning more let me know!
