So, put 2 hours into minutes. You get 120. Now, seeing how you have 20 song requests, and each one takes 3.5 minutes, multiply those two values. Now you have 70. After doing that, just subtract 70 from 120 and get 50.
tada
answer is 50
The point-slope form if the coordinates are (-1,1) and (1,-1)
![\frac{ - 1 - 1}{1 - ( - 1)} = \frac{ - 2}{1 + 1} = \frac{ - 2}{2} = - 1](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%20-%201%20-%201%7D%7B1%20-%20%28%20-%201%29%7D%20%20%3D%20%20%5Cfrac%7B%20-%202%7D%7B1%20%2B%201%7D%20%20%3D%20%20%5Cfrac%7B%20-%202%7D%7B2%7D%20%20%3D%20%20-%201)
y = ax + b = ( - 1 )x + b = - x + b < i guess>
Ok done. Thank to me :>
Answer:
Because they aren't equivalent. Prolog allows the definition of symbols as inline operators using the op/3 predicate, which allows one to convert arbitrary compounds to formulae and back again.
Step-by-step explanation:
Since 2+2 is a compound with arity 2 and 4 is just an atom unification is impossible and the query fails. To actually do arithmetic equivalence you must use =:=/2 (2 + 2 =:= 4). To solve arithmetic problems you must use is/2 or use an interpreter with arithmetic constraint extensions.Yes, the moment you begin to tie math to real world items, it can turn false very quickly. For example:
(2 red balls + 2 blue balls = 4 orange balls) = false
(2 women + 2 women = 4 men) = false
(2 cats + 2 mice = 4 dogs) = false
(2 oxygen as a single molecule (o₂) + 2 oxygen as a single molecule (o₂) = 4 oxygen as a single molecule (0₄)) = false
That is to say, in the real world there is often non-numerical 'metadata' in additional to the numbers being added, such that a perfect equality (beyond mere quantity) is false. This 'metadata' would include everything from size, to composition, to structure, to color, to temperature, to species, to intelligence, to flavor, to temperament, to physical laws of union and relation, and many other properties.
Speed=distance / time ⇒ time=distance / speed.
Data:
distance=17.6 km
speed=11 km/h.
Therefore:
Time=17.6 Km / (11 Km/h)=1.6 hours
Answer: 1.6 hours.
Step-by-step explanation:
V = 1/2 a x c x h
1/2 * 7*12*18 = 756 yd ^3
