WE know 1 day = 24 hours
To find number of hours spent on each activity, we multiply the corresponding percentage by 24
School : 25 % --> 0.25 * 24 = 6.00 hrs
Eating : 10 % ----> 0.1 * 24 = 2.40 hrs
Sleep : 40 % ----> 0.4 * 24 = 9.60 hrs
Homework: 10 % ---->0.1 * 24 = 2.40 hrs
Free time: 15 % -----> 0.15 * 24 = 3.60 hrs
Answer:
2m/s²
Step-by-step explanation:
If for a moving object the force acting on the object varies directly from the objects acceleration, then it can be expressed as:
F∝a
F = ka.
F is the force
a is the object's acceleration
From the expression;
k is the constant of proportionality
When an initial force of 25 N acts on the object and the acceleration of the object is 5 m/s², then
k = 25/5
k = 5Ns²/m
If the force exchange to 10 N, the acceleration of the object will be gotten using the relationship above
F = ka
Given F = 10N and k = 5Ns²/m
a = F/k = 10/5
a = 2m/s²
The acceleration of the object will be 2m/s²
Answer:
i think this is the answer 289
Step-by-step explanation:
have a great day
This is the concept of combination, the number of ways 4 different color can be chosen from 9 different colors will be:
9C4
=(9!)/(4!(9-4)!)
=362,880/(24×120)
=362,880/2880
=126
thus the number of ways is 126 ways
