Name worked these problems myself Math Rules! I worked with others on these probl 5: Twenty-Five 1. Faces Edges Vertices A is a 3 figure with flat surfaces, or faces. Each face is a polygon. Complete the table For each polyhedron rite the number of faces, edges, and vertices. Move one line to form a true equation. 3. Which piece of wrapping paper is too 21 small to wrap the 4. Mom said she would give you an allowance in your choice of 3 plans a. $6.00 a week for 10 weeks. b. $1.00 the first week, $2.00 the second week, $3.00 the third week and so on for 10 weeks c. $0.10 the first week and each week twice the amount of the week before for 10 week whMCH PLAN WILL YOU CHOOSE TO GET THE MOST ALLOWANCE? 2002 Pieces of Learning CLC0241Explanation / Answer
Solution 3.
Here concept of Surface area will be used to judge if the wrapping paper A,B,C are sufficient to wrap the box-
Surface area of box = 2(15*9+9*4+15*4) = 462 unit2
Area which can be covered by paper A = 21*21 = 441 unit2
Area which can be covered by paper B = 16*30 = 480 unit2
Area which can be covered by paper C = 32*18 = 576 unit2
Since Surface area of wrapping paper A is less than surface area of box thus it will be too small to wrap the box.
Solution 4.
(a)Total allowance = $6 a week for 10 weeks= 10*6 = $60
(b) Total allowance = 1+2+3+4+5+6+7+8+9+10 = $55
(c) Total allowance = 0.1 + 2*0.1 + 22*0.1 +23*0.1.......... + 29*0.1
Sum of 10 terma of GP whose first term is 0.1 and ration is 2= 0.1*(210-1)/(2-1) = $102.3
thus plan c would be the plan which would get most allowance.
