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:

Step-by-step explanation:
Let

Full time rates-$275, Part-time rates-$140
The problem can be expressed as:

Express eqtn1 in terms of f,
Substitute f value in eqtn 2.

Therefore, jeds has 17 fulltime and 9 parttime employees.
Answer:
x=100
Step-by-step explanation:
the sum of all 3 angles in a triangle is always 180 so your problem is: 180 - 35 - 45
There are 2 types of ratios: Part-to-Wholes, and Part-to-Part ratios.
Part-to-part ratios show the relationship between the two groups.
Lets say theres 10 fruits in a fruit bowl.
If you have 3 apples, and 7 oranges, then the ratio is 3:7 as the part-to-part ratio. But the part-to-whole ratio would be either 3:10 ( for apples) or 7:10 (for oranges)
