Answer:
-2.5 m/s²
Explanation:
The acceleration of a body is the change in it's velocity with time.
The change in velocity with time can be obtained as the slope of a velocity time graph ;
Acceleration = (change in velocity / change in time)
Taking the slope :
Change in Velocity = △y = y2 - y1
Change in time = △x = x2 - x1
(10, 15) ; (0, 40)
△y / △x = y2 - y1 / x2 - x1 = (40 - 15) / (0 - 10)
△y / △x = 25 / - 10 = - 2.5 m/s²
Answer:
The unit rate is $0.22 lb
Explanation:
The given parameters are;
The price for 18 lb = $3.99
We have;
The unit rate is the price for one unit. Whereby the unit of measurement is the lb, we have that one unit = 1 lb.
Therefore, given that 1 lb = 18 lb/18, the price of 1 lb which is the unit rate is given as follows;
18 lb price = $3.99
Divide both sides by 18 to get;
18 lb/18 = $3.99/18 = $0.221
Therefore, we have;
1 lb = 18 lb/18 = $0.221
The unit rate, which is the cost for 1 lb to the nearest hundredth = $0.22/lb.
