Answer:
(-8) + (-8) + (-8) + (-8)
Step-by-step explanation:
Since Yan is descending ; we represent his movement as being negative.
Number of rungs descended before stopping = 4
Number of stops = 8
Given that no extra steps was taken ;
Number of ladder rungs descended :
4 rungs per stop for 8 stops
- 4 * 8 = - 32 rungs
Another way to write the product :
Number of stops added in number of rungs descended :
(-8) + (-8) + (-8) + (-8)
J can find the height of the fifth member on this way
S=150
S1=153
S2=150
S3=151
S4=152
S5=?
S= (s1+s2+s3+s4+s5)/5:
5*150= <span>153+150+151+152+S5
S5=5*150-606=750-606=144
Answer is 144 cm</span>
