Answer:
Step-by-step explanation:
13. 35ft * 6cm = 210
14. 35ft * 3.2cm = 112
The answer is A. k/6 + 8 - 2/k
Kira's fish caught more the first step to find the answer is find the common denominator so Floyds fish weighed 2/3 and Kira's was 7/8 take 8 X 3 = 24 so 24 is the common denominator now you have to take 2 X 8 =16 and 7 X 3 = 21 so Floyds fish is 16/24 and Kira's is 21/24 making Kira's the bigger fish
Answer:
Surface area of square pyramid is computed as follows:
A = a² + a*√(a² + 4h²)
where <em>a</em> is the base length and <em>h</em> is the height.
If a model of the square pyramid is scaled down by a factor of x, then the surface area will be:
A' = (a/x)² + (a/x)*√[(a/x)² + 4(h/x)²]
A' = a²/x² + a/x * √[a²/x² + 4h²/x²]
A' = a²/x² + a/x * √[(a² + 4h²)/x²]
A' = a²/x² + a/x * √(a² + 4h²)/√x²
A' = a²/x² + a/x² * √(a² + 4h²)
A' = 1/x² * [a² + a*√(a² + 4h²)]
A' = 1/x² * A
That is, the surface area will be 1/x² times the original surface area. If h = 25 ft and a = 15 ft:
A = 15² + 15*√(15² + 4(25)²) = 1008.02 ft²
The factor is not mentioned in the question, nevertheless, the area will be 1008.02/factor² ft²
