Answer:
perimeter = 322.5 ft ( to the nearest tenth of a foot)
Step-by-step explanation:
Length the length of the sides of the square be L
Area of a square = L²
∴ 6,500 = L²
L = √(6,500)
L = 80.6226
Next Let us calculate the perimeter
Perimeter of a square = L + L + L + L = 4L
perimeter = 4 × 80.6226
Perimeter = 322.4904 ft
perimeter = 322.5 ft ( to the nearest tenth of a foot)
<em>N:B rounding to the nearest tenth of a foot is same as rounding to 1 decimal place.</em>
On Monday he ordered 96
On Wednesday he ordered 264
96 + 264 = 360 total books
24 books in each box
360/24 = 15 boxes....he received 15 boxes of 24 books for a total of 360 books
Answer:
$5.5
Step-by-step explanation:
38.50 divided by 7 = x
x = 5.5
B^2=a^2+c^2-2ac*cosB
cosB=(a^2+c^2-b^2)/(2ac)
B=arcos[(a^2+c^2-b^2)/(2ac)]
B=44.664924531140738644131908835392
B≈44.7
