You are baking brownies for your class. There are 28 total students in your class and you have baked 23 brownies. Right and solv

slavikrds [6]

Answer:

$x = 33$

Step-by-step explanation:

Given

$Students = 28$

$Brownies = 23$

$Brownies = 2\ per\ student$

Required

Determine the number of brownies left

If:

$Brownies = 2\ per\ student$

and there are 28 students

Then:

$Total\ Brownies = 2 * 28$

$Total\ Brownies = 56$

To determine the number of brownies left, we have:

$Total\ Brownies = Brownies\ Made + Brownies\ Left$

$56 = 23 + x$

Reorder

$x + 23 = 56$

Collect Like Terms

$x = 56 - 23$

$x = 33$

<em>Hence, there are 33 brownies left</em>

At the circus, a clown is shot from a cannon. This situation can be modeled by the function: h = – 16t2 + 45t + 15, where 'h' is

weeeeeb [17]

Answer:

The maximum height is 46.64 feet.

Step-by-step explanation:

If we take the derivative of h whit respect to t and equal this to zero we would find the value of t which corresponds to the maximum h.

So, we have the function h(t):

$h(t)=-16t^{2} + 45t + 15$

Taking the derivative, we have:

$\frac{dh(t)}{dt}=-32t + 45=0$

Now, we solve it for t:

$t=\frac{45}{32}=1.4\: s$

Finally, we put this value of t into the original equation.

$h(t)=-16(1.4)^{2} + 45(1.4) + 15$

$h_{max}=46.64\: ft$

Therefore, the maximum height is 46.64 feet. All the given options are wrong, the one that comes closest is option A.

I hope it helps you!

A 12 ft. rope is attached to the wall of a garage. A dog’s collar is attached to the end of the rope to allow him to safely stay

Zolol [24]

Since it's a wall, I'm guessing it will only have access to half the circle? Therefore:

<em>Circle area formula: </em>πr²

<em>Radius:</em> 12/2 = 6ft

(π * 6²)/2 =

36π/2 =

18π = 56.55ft²

A drug used to relieve anxiety and nervousness has a half-life of 16 hours. if a doctor prescribes one 2.8-milligram every 24 ho

dlinn [17]

After 24 hours, 35.4% of the initial dosage remains on the body.

<h3>What percentage of the last dosage remains?</h3>

The exponential decay is written as:

$f(x) = A*e^{-k*x}$

Where A is the initial value, in this case 2.8mg.

k is the constant of decay, given by the logarithm of 2 over the half life, in this case, is:

$k = ln(2)/16h$

Replacing all that in the above formula, and evaluating in x = 24 hours we get:

$f(24h) = 2.8mg*e^{-24h*ln(2)/16h} = 0.9899 mg$

The percentage of the initial dosage that remains is:

$P = \frac{0.9899mg}{2.8mg}*100\% = 35.4\%$
