Viktor [21]

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

3d+16=-2(5-3d) solve equation

strojnjashka [21]

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 = $\frac{26}{3}$ = 8.67

Hence The value of d of the given equation is 8.67 Answer

Amy purchased a brand-new mountain bike, which she's riding through

Neko [114]

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

∵ Acceleration is define as the rate of change of velocity

i.e acceleration = $\dfrac{\textrm velocity}{\textrm time}$

or, a = $\dfrac{\textrm v}{\textrm t}$

And

Velocity is define as rate of change of displacement

i.e velocity = $\dfrac{\textrm displacement}{\textrm time}$

Or, v = $\dfrac{\textrm s}{\textrm t}$

Since here displacement is function of time

So , v = $\frac{\partial s(t)}{\partial t}$

Or, v = $\frac{\partial (t³ - 2 t² + 3)}{\partial t}$

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 = $\frac{\partial v}{\partial t}$

Or, a = $\frac{\partial (3 t² - 4 t + 3)}{\partial t}$

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
