Answer:
-2 m/s^2
Step-by-step explanation:
Just as you would calculate the velocity when a body moves from point A to point B in a time T, we are going to calculate the acceleration as the difference of the velocities (final - initial) and divide it by the time it took:
Velocity_final = 10 m/s
Velocity_initial = 20 m/s
Time = 5 s
acceleration = (Velocity_final - Velocity_inital)/Time
= (10 m/s - 20 m/s)/5 s
= (-10 m/s) / 5s
= -2 m/s^2
The acceleration in m/s^2 is -2
Answer:
21 letters.
Step-by-step explanation:
So, what you need to find here is how many letters precede the letter V. You could count the letters, but since V is near to the end of the alphabet, faster way would be to count the letters from behind. We know that the ending streak of the alphabet is ...v, w, x, y, z, and we also know that the english alphabet has 26 letters. So if we count from behind we find that V is fifth letter from behind ( z is 26th, y is 25th, x is 24th, w is 23rd and v is 22nd). Finally, since V is 22nd letter, that means that it is preceded by 21 letter.

Answer:
81 square inches.
Step-by-step explanation:
Draw a diagram to represent what you know.
You don't know the values of the lengths so represent them algebraically.
You know the perimeter is 45 inches and that the perimeter is calculated by the sum of all of the sides of a shape.
You can rearrange to find the value of a side you've denoted as some unknown variable.
The area is given by the product of the sides. Express this algebraically and then input the value you found.
