Answer:
The answer is
<h2>4260 N</h2>
Step-by-step explanation:
The force acting on an object when given the mass and acceleration can be found by using the formula
<h3>Force = mass × acceleration</h3>
From the question
mass = 142 kg
acceleration = 30 m/s²
So we have
Force = 142 × 30
We have the final answer as
<h3>4260 N</h3>

Mark spend 1 hour 10 minutes in reading.
<h3>What is Unitary Method?</h3>
Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Mark spent 1 hour 17 minutes less than Sheila
Sheila spent 55 minutes less than Pete.
Pete spent 3 hours reading.
Since, pete spent 3 hours. So, Sheila spent
= 3 hours or (180 minutes) - 55 minutes
= 2 hours 05 minutes.
Now, Mark spent = 2 hrs 05 minutes - 55 minutes
= 1 hour 10 minutes

According to my calculations the 30% of 570 is 171
10% of 570 is 57
times that by 3 and you get 171
Answer:
The area of the clock 
Step-by-step explanation:
We have been given the face of the clock that is 
So that is also the circumference of the clock.
Since the clock is circular in shape.
So 
From here we will calculate the value of radius 
of the clock that is circular in shape.
Then 
Now to find the area of the clock we will put this value of (r) in the equation of area of the circle.
Now 
So the area of the face of the clock =
No 45 is a multiple for 5
