Answer:
37
Step-by-step explanation:
Let C represent those dressed as heroes and let B represent those wearing mask
Thus;
n(C) = 39
n(D) = 45
We are told that 21 entrants were dressed as heroes wearing a mask.
Thus; n(C n D) = 21
We are also told that there were a total of 100 entries.
Thus, n(T) = 100
Now, number of entrants neither dressed as heroes nor wearing a mask is given by;
n(T) - n(C u D)
n(C u D) = n(C) + n(D) - n(C n D)
n(C u D) = 39 + 45 - 21
n(C u D) = 63
Thus;number of entrants neither dressed as heroes nor wearing a mask is: 100 - 63 = 37
Answer:
Step-by-step explanation:
A monomial is a type of polynomial that has only one term and when there are two terms in the polynomial then it is called binomial.
Say for example (ax) is a monomial and (ax + b) is a binomial.
In our case the cube of a monomial is 
Therefore, the monomial will be ![\sqrt[3]{\frac{a^{27} }{8}} =\frac{a^{9} }{2}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7Ba%5E%7B27%7D%20%7D%7B8%7D%7D%20%3D%5Cfrac%7Ba%5E%7B9%7D%20%7D%7B2%7D)

Answer:
10 units
Step-by-step explanation:
Volume of 1 cube = 1 unit
A = l³
l =∛1000 = 10 ( 10*10*10=1000)
Answer:
x=y+1 and x=y+ 2/3
Step-by-step explanation:
x=y+1 : Add 1 to both sides, switch sides
x=y+ 2/3 : Regroup terms, Subtract 3/2 from both sides, Multiply both sides by -1
Hope this helps!! :)
