Petrich is wrapping four presents for his mom, dad, sister, and daughter. The following are the estimate box sizes:

8.5" × 14.5" × 1.5"
9.5" × 14.5" × 2"
11" × 16" × 3"
15.5" × 12"× 4"

A standard roll of wrapping paper is 30" long with nine feet (three yards) of paper. Determine the minimum amount of rolls of wrapping paper that Petrich needs for all four presents.

Minimum 2 rolls will be required.

Step-by-step explanation:

Surface area of all three boxes = Area of the wrapping paper required

Surface area of Box 1 = 2(lb + bh + hl)

                                    = 2(8.5×14.5 + 14.5×1.5 + 8.5×1.5)

                                    = 315.5 square inches

Surface area of box 2 = 2(9.5×14.5 + 14.5×2 + 9.5×2)

                                    = 371.5 square inches

Surface area of box 3 = 2(15.5×12 + 12×4 + 15.5×4)

                                    = 592 square inches

Surface area of box 4 = 2(11×16 + 16×3 + 11×3)

                                    = 514 square inches

Total surface area = 315.5 + 371.5 + 592 + 514

                               = 1793 square inches

Dimensions of the wrapping paper = 30" × 9 feet Or 30" × 108"

Area of the wrapping paper = 3240 square inches

Number of papers required to wrap all four boxes =  

                                                                                    ≈ 2 rolls  

Therefore, minimum 2 rolls will be required to wrap the presents.                          

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

the most boring thing ever written

step-by-step explanation:

i am writing something. yes, i plan to make it the most boring thing ever written. i go to the store. a car is parked. many cars are parked or moving. some are blue. some are tan. they have windows. in the store, there are items for sale. these include such things as soap, detergent, magazines, and lettuce. you can enhance your life with these products. soap can be used for bathing, be it in a bathtub or in a shower. apply the soap to your body and rinse. detergent is used to wash clothes. place your dirty clothes into a washing machine and add some detergent as directed on the box. select the appropriate settings on your washing machine and you should be ready to begin. magazines are stapled reading material made with glossy paper, and they cover a wide variety of topics, ranging from news and politics to business and stock market information. some magazines are concerned with more recreational topics, like sports card collecting or different kinds of hairstyles. lettuce is a vegetable.
