Answer:
26.4ft²
Step-by-step explanation:
I first converted the centimeter values to feet
140Cm x 30.48 = 4.59
70cm x 30.48 = 2.3
the paper required is approximately equal to the area of the pyramid.
area of pyramid is equal to area of triangle + base²
Are of triangle = 1/2 x b xh
= 4 x 1/2 x4.59x2.3 + (2.3)²
= 2 x 4.59 x 2.3 + 5.29
= 26.4 feet²
therefore it will take 26.4 feet² paper to make each tree, including the bottom.
Answer:
-b -3/2
Step-by-step explanation:
-1/2(8b+3) + 3B (a negative times a positive equals a negative)
1. Mutiply -1/2 by 8b and then by 3
(-1/2 x 8b -1/2 x 3) + 3b
-4b - 3/2 + 3b
2. Add -4b + 3b = -b
-b - 3/2
If we have a common ratio every set amount of time (and not a common difference or addition), this is an exponential relationship. An exponential equation would have a form like Money = (1000)(2)^(# of months), where every additional month would cause the money amount to double.
