If it takes 15 min to load 3 racks of buns, how many hours will it take to load 36 racks?

GrogVix [38]

Set up the equation of two ratios:

3 racks 36 racks
----------- = --------------
15 min x

Solve this for x: 3x =540; x = 180 minutes, or 3 hours

*Awarding Brainliest to first responder with the correct answer!*<br><br> What is m∠CDJ ?

Bogdan [553]

Answer:

Step-by-step explanation:

Angle ADC and angle CDJ are complementary. That means that they add up to equal 90 degrees. Therefore,

4x + 3x - 8 = 90 and

7x = 98 so

x = 14

Sub in a 14 for x in 3x - 8:

3(14) - 8 = 34

Angle CDJ = 34 degrees

Answer:

C) 6 feet

Step-by-step explanation:

The diagram is shown in the attachment.

Using the Pythagoras Theorem,

$x^2=4^2+4^2$

$x^2=16+16$

$x^2=32$

We take positive square root to obtain

$x=\sqrt{32}$

$x=4\sqrt{2}$

x=5.66ft

Rounding to the nearest feet we have x=6ft

The position equation for a particle is s of t equals the square root of the quantity t cubed plus 1 where s is measured in feet

vladimir1956 [14]

$\bf s(t)=\sqrt{t^3+1}
\\\\\\
\cfrac{ds}{dt}=\cfrac{1}{2}(t^3+1)^{-\frac{1}{2}}\cdot 3t^2\implies \boxed{\cfrac{ds}{dt}=\cfrac{3t^2}{2\sqrt{t^3+1}}}\leftarrow v(t)
\\\\\\
\cfrac{d^2s}{dt^2}=\cfrac{6t(2\sqrt{t^3+1})-3t^2\left( \frac{3t^2}{\sqrt{t^3+1}} \right)}{(2\sqrt{t^3+1})^2}\implies 
\cfrac{d^2s}{dt^2}=\cfrac{ \frac{6t(2\sqrt{t^3+1})-1}{\sqrt{t^3+1}} }{4(t^3+1)}$

$\bf \cfrac{d^2s}{dt^2}=\cfrac{6t[2(t^3+1)]-1}{4(t^3+1)\sqrt{t^3+1}}\implies 
\boxed{\cfrac{d^2s}{dt^2}=\cfrac{12t^4+12t-1}{4t^3+4\sqrt{t^3+1}}}\leftarrow a(t)\\\\
-------------------------------\\\\a(2)=\cfrac{215~ft^2}{44~sec}$
