Answer:
21.42857143 = n
Step-by-step explanation:
Is means equals and of means multiply
12 = 56% *n
Change the percent to a decimal
12 = .56*n
Divide by .56
12/.56 = .56n/.56
21.42857143 = n

Answer:
The value of d of the given equation is 8.67
Step-by-step explanation:
Given equation as :
3 d + 16 = - 2 × ( 5 - 3 d )
Or, 3 d + 16 = - 10 + 6 d
Or, 16 + 10 = 6 d - 3 d
So , 26 = 3 d
∴ d =
= 8.67
Hence The value of d of the given equation is 8.67 Answer
Answer:
The Acceleration of bike after 3 minutes of ride is 14 meter² per minutes
Step-by-step explanation:
Given as :
The displacement of bike is the function of time
i.e s(t) = t³ - 2 t² + 3 meters
The Time of bike acceleration = t = 3 minutes
Let The Acceleration of bike = a meter² per minutes
Now, According to question
∵ <u>Acceleration is define as the rate of change of velocity</u>
i.e acceleration = 
or, a = 
And
<u>Velocity is define as rate of change of displacement</u>
i.e velocity = 
Or, v = 
Since here displacement is function of time
So , v = 
Or, v = 
Or, v = 3 t² - 4 t + 3
So, velocity is the function of time = v = 3 t² - 4 t + 3 meter per minutes
Now, Again
Acceleration = a = 
Or, a = 
Or, a = 6 t - 4
∴ Acceleration is the function of time = a = 6 t - 4
Now, Acceleration of bike after 3 minutes
So, at t = 3 min
i.e a = 6 t - 4
Or, a = 6 × 3 - 4
Or, a = 18 - 4
∴ a = 14 meter² per minutes
Hence, The Acceleration of bike after 3 minutes of ride is 14 meter² per minutes . Answer
