Answer:
4 airplanes
Step-by-step explanation:
1 = 2/3
6 = x
cross multiply
x = 6 × 2/3
therefore x = 4
Step-by-step explanation:
cross multiply all equations seperately
1,n=63
2.n=24
3.n=19
4.n=20
Answer:
452.39
Step-by-step explanation:
to find the surface area of a sphere all you need is the radius (half the diameter) and assuming the sphere touches both top and bottom that makes the radius 6 so your equation is
SA=4πr^2
SA=4*π*6^2
SA=4*π*36
SA=4*113.09
SA=452.389
then rounded up to 452.39, that is your answer
9514 1404 393
Answer:
28
Step-by-step explanation:
The diagonals of the parallelogram are AC and BD. The way the diagram is drawn, BD is the long diagonal, said to be 24 inches. AC is the short diagonal, said to be 12 inches.
Since AC bisects BD at point E, point E is the midpoint of BD. That means BE = (24 inches)/2 = 12 inches.
Since BD bisects AC at point E, point E is the midpoint of AC. That means EC = (12 inches)/2 = 6 inches.

Now, we know the lengths of the sides of ΔBEC, so we can find its perimeter. The perimeter of any geometry is the sum of the lengths of its sides.
perimeter ΔBEC = CB +BE +EC
perimeter ΔBEC = 10 in + 12 in + 6 in = 28 in
The perimeter of triangle BEC is 28 inches.
