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.
The answer is 3 1/4 which is last choice
Answer:
CHILDREN= 389
ADULT=310
Step-by-step explanation:
1) A + C = 710 2) A*2.50 + C*1.2 = 1288.75
OR, A= 710-C (710-C)*2.50 + C*1.2=1288.75
1775-2.50*C+1.25*C=1288.75
1775 -1.25*C = 1288.75
-1.25*C=1288.75-1775
1.25*C=486.25
C = 486.25/1.25
C = 389
Again or, A + C = 710
A = 710 - C
A = 710 - 389
A = 321
Answer:
$18.77
Step-by-step explanation:
Given that the taxes paid include the state sales tax and the country sales tax. The tax paid is the product of the total tax rates and the price of the handbag. Alternatively, the individual tax rates may be applied on the price of the handbag and the sum of the results gives the tax Yui paid for the purchase.
Total tax rate
= 2.63% + 5.9%
= 8.53%
Tax paid
= 8.53% * $220
= $18.77
