Answer:
1.56%
Step-by-step explanation:
A standard deck of cards has 52 cards, and 13 of these are hearts, as there are 4 suits, and 52/4=13. This means the probability of choosing a heart card from a deck of cards is 1/4, or 25%. Now to find the probability of doing this from 3 decks in a row, we simply cube 1/4 to get 1/64, and in percentage this is ~1.56%.
Yes all trapezoids are quadrilaterals
Density = mass/volume
the mass is 10578.9 pounds
the volume of a sphere is v = 4/3 πr^3
v = (4/3) (π) (4.3)^3
v = 333.04
10578.9 / 333.04 = 31.76
the final density is 31.76!!
