Answer:
307 paces
Step-by-step explanation:
First, lets convert Robert's pace to metres. (cm > m)
75cm = (75/100)m
= 0.75m
Number of Full Paces = Length of Bridge / 1 Full Pace
=

See , we must have full paces, and in this case we are finding the minimum number of paces, so we will be looking at the lowest possible whole number, which in this case, is 307 paces.
Answer:
55.5 kg.
Step-by-step explanation:
Potential energy = mgh
= m * 9.81 * 4.5 = 2450 where m is the mass of the man.
m = 2450 / (9.81* 4.5)
= 55.5 kg.
nCr(20, 2) = 190 ways of selecting 2 from 20
nCr(10, 1) = 10 ways of selecting 1 from 10
To find the over all probability of winning,
Calculate the Harmonic Mean (19) and divide by 2
Equivalent to
1/ (1//190 + 1/10) =9.5
So the probability is 1/9.5 = 2/19.
Idk what the dollar signs or what the letters represent, would help but doesnt make sense
Step-by-step explanation:
The variables w, x, and z are not needed because this expression only contain one variable, y
y= 5 It says it in the problem
Start by substituting the value of y into the expression
y+5 = 5+5
Solve
5+5 = 10
Solution: y+5 = 10
I hope this helps!!!
