$12.95 for 3 pounds of nuts or $21.45 for 5 pounds of nuts
Zarrin [17]

First, find the base rate of both of the numerals, to do this simply divide the price by the number of units.

12.95 divided by 3 is 4.32 ( rounded to nearest cent )

21.45 divided by 5 is 4.29 ( rounded to nearest cent )

So, if you want the better deal ( which is what I've interpreted ), then 5 pounds of nuts is the better deal <u>BY</u> 3 cents.

Hope this helps, if not, comment below please!!!!

2X+4=20+5X<br>A)1/2 B)-1/2 C)2 D)-2​
Nookie1986 [14]

Answer:

It seems that your options aren't correct as the right answer is -5.3333... (recurring)

Step-by-step explanation:

1)  2x + 4 = 20 + 5x   (subtract by the smallest unknown)

  -2x                  -2x

2)  4        = 20 + 3x

    -20      -20    (now subtract each side by 20 as we want to leave the unknown on one side and another number on the other side.

3) -16       = 3x   (Divide each side by 3)

   ÷3        = ÷3

4) -5.33333... = x

<h3>Now we have found x but if you're unsure you can substitute to see if your answer is correct.</h3><h3>2 x -5.3333 + 4 = -6.6666</h3><h3>20 + 5 x -5.3333= -6.6665</h3><h3>Our answer is correct! (When answers are rounded, it is equal to the same thing).</h3>

Am i correct? calculus
Advocard [28]
Check the picture below.

now, the "x" is a constant, the rocket is going up, so "y" is changing and so is the angle, but "x" is always just 15 feet from the observer.  That matters because the derivative of a constant is zero.

now, those are the values when the rocket is 30 feet up above.

\bf tan(\theta )=\cfrac{y}{x}\implies tan(\theta )=\cfrac{y}{15}\implies tan(\theta )=\cfrac{1}{15}\cdot y&#10;\\\\\\&#10;\stackrel{chain~rule}{sec^2(\theta )\cfrac{d\theta }{dt}}=\cfrac{1}{15}\cdot \cfrac{dy}{dt}\implies \cfrac{1}{cos^2(\theta )}\cdot\cfrac{d\theta }{dt}=\cfrac{1}{15}\cdot \cfrac{dy}{dt}&#10;\\\\\\&#10;\boxed{\cfrac{d\theta }{dt}=\cfrac{cos^2(\theta )\frac{dy}{dt}}{15}}\\\\&#10;-------------------------------\\\\&#10;

\bf cos(\theta )=\cfrac{adjacent}{hypotenuse}\implies cos(\theta )=\cfrac{15}{15\sqrt{5}}\implies cos(\theta )=\cfrac{1}{\sqrt{5}}\\\\&#10;-------------------------------\\\\&#10;\cfrac{d\theta }{dt}=\cfrac{\left( \frac{1}{\sqrt{5}} \right)^2\cdot 11}{15}\implies \cfrac{d\theta }{dt}=\cfrac{\frac{1}{5}\cdot 11}{15}\implies \cfrac{d\theta }{dt}=\cfrac{\frac{11}{5}}{15}\implies \cfrac{d\theta }{dt}=\cfrac{11}{5}\cdot \cfrac{1}{15}&#10;\\\\\\&#10;\cfrac{d\theta }{dt}=\cfrac{11}{75}
