It is certainly not directly proportional with time .
This time it is directly proportional with time.
7·s - 5·t + 2·u is the expression being questioned .
The purple part is 1/4 ths of the ring.
1011 is not divisible by 11 but 990, 1001 and 1012 are. Consider the first term as (1012-1)^{2·m} .
If (1012-1)^{2·m} is expanded, the constant term will be "+1" because the powers are even. And all other terms are multiples of 11 .
The term n^{2} will have a residue of 0 if multiple of 11. Have please a look at ry1 for further help.
The questions may be complex or may seem to be complex, right choice is to try to attain the maximum possible out of them .
Looking carefully it is possible to see that h_{1} and h_{2} are not among the given data, which of course means only the second (at right)
may be tried/questioned.
Be careful about the units. Density is given as 1 g /cm^{3} which is the same as 1000 kg/m^{3} . Velocities are given as cm./s. and are to
be converted to m./s. (2 m./s. and .6 m./s.) because pressure is given as Newton/m^{2}. Then we have to compare 1037 + 500·2^{2} = 3037 and 2932 + 500·(.6)^{2} = 3112.
3112-3037 = 75 and 75/3037 is .024 (rounded, 2% approximate).
the unknown a has a coeff of 4 ...
5 will only be correct if A=B .
(b-5)^{2}= ?
(a-10)^{10} = (10 - 10)^{10} = 0^{10} = 0·0 ... 0·0 .
Have please a look at ry1 .
After a month the yield will be x - x/20 = x·(1-1/20) .
The shortest distance is of length 8·x . There are ... of them .
This is a rather hard question. If not solved, have please a look at the web page
"http://www.test-dr.com/education/6th-Grade-Mathematics/probability-5.1.1.html" /question-18 and it's helps.
a and b may be any natural number between 10 and 99 ...
Take the representation (n-2)·n·(n+2).
The sum is 1/4 ths of ...
The first day after the birth it will be x_{1} = (1- 1.7/1000)·x . For further help have please a look at ry1 .
The duration of drive is 100-t minutes i.e. (100-t)/60 hours. Average drive velocity 60·120 / (100-t) km./h .
The constant term is 91-21=70 .
Subtract "n" from both sides to get -17·n - 7 - 14·(n - 2) = r and simplify .
Primes less than 10 are 2,3,5 and 7 . For the time being, trial and error is must . Excellent if you do without having a look at ry1.
