is the area of a paperback book cover closer to 28 sqaure inches or 28 sqaure centimeters? tell how you decided
Answers
I would say 28 square inches. Imagine that we divide the number and we get 4 and seven. your average paperback book is about 4 inches wide and 7 inches tall. If we multiply it back, we get 28 square inches. Hope it helps! -Lacy
It would be centimeters becuase square inches is a very large area, much larger than a typical book. Therefore, the paperback book would most likely be 28 square centimeters
The product the lies between__and__. 3×3/4?
Answers
Saying 3/4 * 3 is the same thing as saying 3/4 of 3. Imagine you have 3 pies, each cut into 4 slices. That would be 3 * 4 = 12 slices of pie, right? So when there's 12 slices, that would be 4/4 of the pies, since all the pieces are there. To find out how many pies we would have with 3/4 of the pie left, we just need to multiply the original equation.
3 * 3/4 = 2 1/4
The product of those two numbers lies between 2 and 3. Hope that helped =)
Becky wants to fence in a rectangular play area for her dog. If she was 82 feet of fencing and wants the length of the play area to be 9 feet longer than its width then what should the dimensions of the play area be?
Answers
ok fencing=perimiter perimiter=L+L+W+W=2L+2W=2(L+W) 82=2(L+W) divid eboth sides by 2 for ease of use 41=L+W
if she wants legnth to be 9 more than width, then L=9+W subsitute 9+W for L 41=9+W+W 41=9+2W subtract 9 32=2W divide 2 16=W
subsitute L=9+W L=9+16 L=25
the pen should be 25 feet by 16 feet
length= width+9 ----- Now we can substitute length with width! Perimeter = 2(length) + 2(width) Perimeter = 82 82= 2(w+9) + 2w 41 = w+ 9 + w 41-9 = 2w 32 = 2w 16= w (now plug w into the equation for length) length = 16 + 9 = 25
