The expression for calculating a percentage is whatever% of anything is simply (whatever/100) * anything.
The total 800 + 1250 + 120 + 625 + 65 equals 2860.
Rhonda does not earn a commission on the first 2000, only on the excess amount, which is 860.
Calculating 15% of 860 involves (15/100) * 860.
Answer:
0.012 km/hr
Step-by-step explanation:
(1200 cm)(1 m/100 cm)(1 km/1000 m) = 0.012 km/hr
Answer
(a) dy/dt = 68 - 3.72t
(b) 64.28 m/s
Step-by-step explanation:
Given y = 68t - 1.86t²
The average speed describes the change in distance over time, represented by dy/dt.
To find dy/dt, we differentiate y with respect to t, resulting in:
dy/dt = 68 - 2(1.86)t
= 68 - 3.72t
(a) dy/dt = 68 - 3.72t
(b) To determine the speed at t = 1, input t = 1 into dy/dt.
dy/dt at t = 1 is:
68 - 3.72(1)
= 68 - 3.72
= 64.28
The speed at t = 1 amounts to 64.28 m/s
