Surprised I got that.
360 - 42 - 42 - 72 - 72 = 132

A restaurant bill is $76.25. How much would a 15% tip be?

miv72 [106K]

Answer:

$11.43

Step-by-step explanation:

use a calculator and type in 76.25 + 15%, which will equal 87.68.

Then you subtract 76.25 from 87.68. 87.68 - 76.25 = 11.43.

A 15% tip would be $11.43

A ball is shot upward from a slingshot at a velocity of 15 m/s the height of the ball after t seconds is given by h(t)=10+ 5t+1/

otez555 [7]

Answer:

The instantaneous velocity after eight seconds is 9 m/s

Step-by-step explanation:

Given as :

The ball shot upward with velocity of 15 m/s

The height of the ball after t sec is given as h(t) = $10 + 5t + \frac{1}{4}t^{2}$

Now, The instantaneous velocity after 8 sec = $\frac{\partial h(t)}{\partial t}$

Or, The instantaneous velocity = $\frac{\partial (10 +5t + \frac{1}{4}t^{2})}{\partial t}$

or, The instantaneous velocity = $5 + \frac{1}{4}\times 2 t$

Now at t = 8 sec

The instantaneous velocity = 5 + 4 = 9 m/s

Hence The instantaneous velocity of ball at t = 8 sec , is 9 m/s Answer
