Given that the elevator can only hold 4 people and that "people" could be either men "M" or woman "W", the possible combinations are as follows
WWWW = 0 men, 4 women = (0,4)
MWWW = 1 man, 3 women = (1,3)
MMWW = 2 men, 2 women = (2,2)
MMMW = 3 men, 1 woman = (3,1)
MMMM = 4 men, 0 woman = (4,0)
Answer:
63
Step-by-step explanation:
6*(-3)= -18
2+(-18)= -16
3*(-16)= -48
15- -48= 63
Answer:
30
Step-by-step explanation:
All the degrees of a triangle should add up to 180 degrees.
D = F
D and F are not equal to 90.
If E = 30, D and F both equal 75.
75(2) + 30 = 180.
Answer:
4√5
Step-by-step explanation:
Use Pythagorean theorem
a^2=21^2-19^2
a^2=441-19^2
a^2=441-361
a^2=80
a= √80
