- A study fonds that the metabolic rate of mamals is proportional to the mass of the mamal carried to the exponent of (3/4). By what factor does the metabolic rate of a 70.0 kg human exceed that of a 6.30 kg cat?\ 70.0 3/4 kg = 6.09 6.303/4 kg I set up the values as a ratio and came up with 6.09. OK, I answered my own question. That is the correct answer.(a) A pyramid has a height of 465 ft and its base covers an area of 12.0 acres (see figure below). The volume of a pyramid is given by the expression V = 1 3 -Bh, where B is the area of the base and h is the height. Find the volume of this pyramid in cubic meters. (1 acre = 43,560 ft²) 2294276.22 m³ (b) What If? If the height of the pyramid were increased to 520 ft and the height to base area ratio of the pyramid were kept constant, by what percentage would the volume of the pyramid increase? 99.95 X %The answer seems incorrect. Maybe it's because of multiplying wrong angles while calculating the x and y components. Please recheck and correct the answer.
