The answer to this question is D.
Yes because if you simplify 24 and 4 weeks(28 days) by 2 than you would get 12 and 2 weeks(14 days)
Answer:
<u>Step-by-step explanation:</u>
least common multiple of the given three numbers can be found out as follows
first have to divide all three numbers by factors that are common for all three
so first divide 55, 75 and 115 by 5
55/5 = 11
75/5 = 15
115/5 = 23
there are no common factors shared by 11, 15 and 23
so the factors are 5, 11 , 15 and 23
so to find the least common multiple
we have to find the products of the factors
5 x 11 x 15 x 23 = 18 975
least common multiple is 18 975
Answer:
Depth = 7.06 m
Velocity = 11.77 ms-1
Step-by-step explanation:
We use the equation of motion:-
s = ut + 1/2 g where s = distance fallen , t = time , u = initial velocity and g = 9.81 ms^-2 , the acceleration due to gravity.
So s = 0(t) + 1/2 * 9.81 (1.2)^2
= 7.06 m to nearest tenth.
We use another equation of motion to find the final velocity:-
v^2 = u^2 + 2gs where v = final velocity
v^2 = 0 + 2*9.81 * 7.06
= 138.52
v = √138.52 = 11.77 m s-1
