Answer:
1/64
Step-by-step explanation:
Step-by-step explanation:
The displacement of a particle d (in km) as a function of time t (in hours) is given by :
Displacement at t = 4 hours,
Velocity of particle is given by :
Velocity at t = 4 hours,
Acceleration of the particle is given by :
At t = 4 hours,
Therefore, the displacement, velocity and acceleration at t = 4 hours is 205 km, 136 km/h and 58 km/h² respectively.
Answer:
1.5625%
Step-by-step explanation:
P(correct) = 1/4
Since all the attempts are independent, probability of all three correct is:
¼ × ¼ × ¼
1/64
1/64 × 100
1.5625%
Where are the choices ? ? There are 30 marbles in the bag, and 3 of them are black. So the probability of getting a black with a random draw is 3/30 = 10% .
Answer: First Option
The approximate price of a pint of veggies is $1.75
Step-by-step explanation:
if v represents the cost of a pint of cut vegetables and f represents the cost of a pint of cut fruits then the equation that models the cost of "v" vegetables and "f" fruits is:
Where z represents the total cost of buying "v" vegetables and a "f" pints of fruits.
h represents the cost of a pint of cut vegetables .
We know that the cost "z" of 5 vegetables pints and 7 fruits pints is $ 28.70
So:
We substitute these values into the equation and solve for h.
