Answer:
Step-by-step explanation:
if Nathan walks 6 miles in 2 hours
6/2=3 miles/ hour
in 9 hours
9*3=27 miles
Another way of writing it is in expanded notation
Sin 45° = opposite side length/hypotenuse length
Cross Multiply and you get
opposite side length = hypotenuse length x Sin 45°
Now all You need to know is the hypotenuse length. It will help you find the opposite side length.
HOPE THIS WILL HELP.
Answer: The answer is 27600 and 35152.
Step-by-step explanation: Given that the call letters of a radio station must have 4 letters and the first letter is one of K or W. We are to calculate the number of call letters that can be made if repetition is allowed and not allowed.
If repetition is not allowed, then we can choose the first letter in 2 ways, second letter in 25 ways, third letter in 24 ways and fourth letter in 23 ways. So, the total number of call letters will be
If repetition is allowed, then we can choose the first letter in 2 ways, second letter in 26 ways, third letter in 26 ways and fourth letter in 26 ways. So, the total number of call letters will be
Thus, the required answer is 27600 and 35152.
Answer:
the Kinetic Energy of the marble at the later point is 0.0007 J
Step-by-step explanation:
Given;
initial potential energy of the marble, P.E₁ = 0.0018 J
final potential energy of the marble, P.E₂ = 0.0011 J
At the initial starting point, the total mechanical energy is;
M.E = K.E + P.E
at the initial starting point, velocity = 0
M.E = 0 + P.E
M.E = P.E = 0.0018 J
At some point later, the total mechanical energy is;
M.E = P.E + K.E
0.0018 J = 0.0011 J + K.E
0.0018 J - 0.0011 J = K.E
0.0007 J = K.E
Therefore, the Kinetic Energy of the marble at the later point is 0.0007 J
