If it is just an estimate then it would be around <em>4</em>. 15.1 is pretty close to 16 which has a perfect square root of 4. Since it is a square both length and width would be the same. To check it you can just square 4 or 4 times 4 and get 16. Hopefully I helped! And sorry if I am wrong.

BTW the exact answer would be 3.88~ (square root of 15.1) just incase you needed that. :)

Two 2 1/2 inch plastic strips and two 5 1/3 inch plastic strips are used to form a rectangle. What is the perimeter of the recta
svp [43]
In this question the given information's should be closely noted. The length and width of the perimeter are already given. Based on those information's the answer to the question can be easily deduced.
Length of the rectangle = 2 1/2 inch
                                       = 5/2 inch
Width of the rectangle = 5 1/3 inch
                                         = 16/3 inch
Then
Perimeter of a rectangle = 2 ( Length + Width)
                                        = 2 [(5/2) + (16/3)]
                                         = 2 [ (45 + 32)/6]
                                         = 2 * (77/6)
                                         = 77/3 inch
                                         = 25 2/3 inch
So the perimeter of the rectangle in question is 25 2/3 inch. I hope the procedure is clear to you.

Tom wants to buy some protein bars and magazines for a trip he has decided to buy three times as many protein bars with magazine
kumpel [21]

Answer:12 Protein bar and 3 magazines

Step-by-step explanation:

Given

Tom purchases Protein bars 3 times as much as magazine

Each bar cost  \$ 0.7

Each magazine costs \$ 2.50

Sales tax is 6.5 %

suppose Tom buy x magazines so

Price of magazine is 2.5 x

Price of bars is 3\times 0.7x=2.1 x

Total Price=2.5 x+2.1 x=4.6 x

After sales tax =4.6x(1+0.065)=4.899 x

This must be less than \$ 20

so 4.899x < 20

x< 4.082

thus x=4

so he but 4 magazines and 12 protein bars
