perimeter = 2L +2W
the problem states the length ( L) is 2 meters longer then width, so L = w+2
so perimeter =2(w+2) +2w
24 = 2(w+2) +2w
24 = 2w+4 +2w
24 = 4w+4
20=4w
w=20/4 = 5
Answer:
3 minutes would be 0.05 hours.
Step-by-step explanation:
Simply divide the minute value by 60 and you get 0.05.
Answer:
108.75 square meter.
Step-by-step explanation:
<h3>Surface area of pentagon based pyramid:</h3>
Here, b is the base length of the pyramid. b = 3 m
a is the apothem of the pyramid. a = 3.5 m
s is the slant height of the pyramid. s = 11 m
The bases of triangles are paralleles, so the angles are the same, the sum og the interior angles are always 180° in a triangle, so 180 - 55 -60 = 65°
x = 65°
y = 60°
z = 55°
The answers are B and C (74 and 80)
The square root of 74 is approx 8.6 and that is between 8 and 9
The square root of 80 is approx 8.9 and that is between 8 and 9
~~hope this helps~~
