Answer: PN = 8√2 ≈ 11.3

<u>Step-by-step explanation:</u>

Perimeter of a square: P = 4s

Given: P = 64 → 64 = 4s

16 = s

Using the 45-45-90 rule: If the sides are 16, then the hypotenuse (diagonal) = 16√2

Since we only need half of the diagonal, (16√2)/2 = 8√2 ≈ 11.3

marta [7]

S= number of small boxes
l= number of large boxes

equation 1: s+l=120
equation 2: 15s+45l=3300

solve by elimination, multiply equation 1 by -15.

-15(s+l=120) = -15s-15l=-1800 add to equation 2.

-15s+15s-15l+45l=-1800+3300 = 30l=1500

30l=1500 , l=50

s+l=120, s+50=120 --> s=70

Answer:

{3¢, 28¢} or {4¢, 19¢} or {7¢, 10¢}

Step-by-step explanation:

54 = 1×54 = 2×27 = 3×18 = 6×9

Possible values of the stamps are 1 more than the values of a pair of factors. Of course, a 2¢ and 55¢ stamp will not permit paying 54¢ in postage, so that combination won't work. However, other pairs that will work are ...
