Answer:
18ft
Step-by-step explanation:
6ft -> 4ft shadow
6 = 4m
m = 6/4
y = 12m
y = 12(6/4)
y = 18ft
Answer:
130
Step-by-step explanation:
just apply rhe formula of trapezium i.e. 1/2(a+b)h
a is the upper side/base
b is the lower side/base
h is the height
Answer:
1/4 - unlikely
0.0 impossible
5/10 - equally likely
100% - certain
75/100 - likely
Step-by-step explanation:
For probability, 0 means impossible and 1 means every single time.
So 1/4 is possible, but unlikely.
5/10 is 0.5 which is right between, so equally likely
75/100 is possible and likely
Sn=(a1)((1-r^n)/(1-r))
=(-11)(1-(-4)^7)/(1-(-4))
=(-11)(1-(-16384))/5)
=(-11)(3277)
=-36047
