2^4-1 so 2•2•2•2=16 and 16-1 is 15
Given:
Hexagonal pyramid
To find:
The edges of an hexagonal pyramid.
Solution:
Edges means lines which connecting to vertices.
Edges in the base of the pyramid:
AB, BC, CD, DE, EF, FA
Edges in the triangular shape of the pyramid:
AG, BG, CG, DG, EG, FG
Therefore edges of an hexagonal pyramid are:
AB, BC, CD, DE, EF, FA, AG, BG, CG, DG, EG, FG
If you mean .152 bar as in .152152152.....then let x=.152 then:
1000x-x=152.152-.152
999x=152
x=152/999 (this cannot be reduced any further as they have no common primes)
Answer:
8 + 2x = 30
Step-by-step explanation:
Given,
The initial number of push-ups he does in each day = 8,
And, the number of push-ups, he increases per day = 2,
Let x be the number of days after he will reach his target of 30 push-ups,
Since, the number of push-ups she will increase in x days = 2x,
Thus, the number of push-ups she will do after x days = 8 + 2x,
⇒ 8 + 2x = 30, which is the required equation.
