Answer:
60.6528 kg
Step-by-step explanation:
Assuming the solid ball of iron is a sphere with a radius of 18 cm (or 0.18 m), we can compute the volume of the sphere:
Therefore, the volume of the solid ball is 0.007776 m³
Since we know that density is mass/volume, then we can find the mass of the iron:
Thus, the mass of the solid ball of iron is 60.6528 kg
Answer:
5in.=15ft. 2in.=6ft.
Step-by-step explanation:
What you have to do is translate 6ft. into inches which is 72in. Then you divide that by 2in. From that you get 36in. You then take that 36in. and multiply it by the 5in for the length. from that you get 180in. You divide the 180in. by 12 to turn your inches into feet and you end up with 15ft.
I hope this helps.
Answer:
m=25/12
Step-by-step explanation:
multiply the reciprocal of 2/5 on both sides
There are 
ways of drawing a 4-card hand, where
is the so-called binomial coefficient.
There are 13 different card values, of which we want the hand to represent 4 values, so there are 
ways of meeting this requirement.
For each card value, there are 4 choices of suit, of which we only pick 1, so there are 
ways of picking a card of any given value. We draw 4 cards from the deck, so there are 
possible hands in which each card has a different value.
Then there are 
total hands in which all 4 cards have distinct values, and the probability of drawing such a hand is
The answer is 6.601, and therefore, the second option.
