I think it’s the last one I am not sure tho
Answer:
The acceleration is: a = -2 m/s²
The negative sign indicates that velocity is decreasing with time.
Step-by-step explanation:
Given
- Initial velocity u = 10 m/s
To determine
Acceleration a = ?
Using the formula to determine the acceleration
a = (v - u) / t
substituting u = 10 m/s, v = 0 and t = 5
a = (0 - 10) / 5
a = -10 / 5
a = -2 m/s²
Thus,
The acceleration is: a = -2 m/s²
The negative sign indicates that velocity is decreasing with time.
Answer:
The expression for the total cost of the visit to dentist is T = 50 + 100n .
Step-by-step explanation:
As given
The price of a visit to the dentist is $50.
If the dentist fills any cavities, an additional charge of $100 per cavity gets added to the bill.
If the dentist n cavities .
Let us assume that the total cost of the visit to dentist be T.
Than the expression becomes
T = 50 + 100n
Therefore the expression for the total cost of the visit to dentist is T = 50 + 100n .
Answer:
its B
Step-by-step explanation:
Answer:mick share is £4 while Sharon share is £8
Step-by-step explanation:
Money to be shared=£12
Mick : sharon=2:4
Sum of ratio=2+4=6
Mick share=2/6 x 12
Mick share=(2x12)/6
Mick share=24/6
Mick share=4
Sharon share=4/6 x 12
Sharon share=(4x12)/6
Sharon share=48/6
Sharon share=48/6
Sharon share=8
