Problem #1-The Summertime Auction House

Directions: Use the attached sheets to head and label each step as to what the task is and then show/label work under that task heading Number each task followed by each part to accomplish the task, example: Problem 1: Find the total money collected by the Summertime Auction House - Task A: Solve for the total of all items sold, show verbal models/label work. Task B: -Solve for the % of tax on all items sold, then show verbal modes/label work, Task C: Find total do Summertime Auction House, etc. until the problem is completed, The total amount do Summertime Auction is involves money, round all final answers to the 100 place. Lost in any step? Think of how to apply those things that we have learned such as: Commission, sales tax, profit. % changes as an increase or decrease, finding the %, part, or whole. Problem 2: . Since this problem

Given:

You are an Auctioneer (look it up or ask if needed) and have sold ten items, a plano e$2,125, a Pakistani hand woven rug @$5,000, a Tiffany lamp @ $875, and other miscellaneous items totaling $520. California Tax rate is 9% and the Summertime Auction house adds an auction fee to the items that goes to the auctioneer for their services. The auctioneer received $681.60. Note that the auctioneer does not get any portion of sales tax because if we think about it, they did not sell any tax.

Your job is to: Problem 1: Find the total amount owed to the auction house at the end of the day. Problem 2: Find the percent commission that the auctioneer charges for services, Problem 3: Find the percent change in total funds received after the auctioneer has been paid excluding tax.
can someone please help me solve this it's worth 20 points of my grade but I don't get it my teacher wants it due tomorrow please.

Complete the worksheet. use 3.14 for π and round all decimals to the nearest hundredth.find the volume of the composite three-dimensional figure above. important terms are written in bold.1. the pyramid has a square base that is inscribed in the circular base of the cone. draw an image of the composite shape of the base. 2. if the side length of the square base is 8 units long, what is the diameter of the circular base of the cone from the picture in number 1? 3. now that the diameter has been calculated, what is the circular area of the cone? ignore the square base of the pyramid.? 4. what is the formula for volume of a cone? 5.to calculate the volume of the cone, the height is still needed. if the cone has a lateral surface with a length of 13 units, what is the height of the cone? 6.now find the volume of the cone. do not include the empty space for the pyramid. 7.. the side length of the square base of the pyramid is 8 units long. what is the base area of the pyramid? 8.what is the formula for the volume of a pyramid9. since the cone and the pyramid share the same vertex, what is the volume of the pyramid10.using the volume of the cone and the pyramid, find the volume of the composite shape. remember, the pyramid is empty. 11,. referring to the picture in number 1, what is the area of the composite base knowing that the square is empty? 12what is the formula to find the lateral surface area of a cone? (13find the lateral surface area of the cone14what is the lateral surface area shape of the pyramid? what is the formula for its area? 15to find the lateral surface area of the pyramid the length is still needed. calculate the lateral surface length of the pyramid. 16 now that the lateral surface length is known, what is the lateral surface area of the pyramid17. using the lateral surface areas of the cone and pyramid, along with the area of the composite base, what is the total surface area?
