Use ratio and proportion:

$29.50 is to 250 ft. as how much is to 40 ft.

29.5 / 250 = x / 40

x = 40(29.5) / 250

x = 1180 / 250

x = 4.72

40 ft. would cost $4.72

Here's how you solve it!

250/2950 = 40/x

x(250/2950) = (40/x)x

250x/2950 = 40

2950(250x/2950) = (40)2950

250x = 118,000

250x/250 = 118,00/250

x = 472

The cost of 40 ft of cable is 472.

Hope this helps! <3

Draw a set of objects where you can find a fractional part of the group using the total number of objects by using subgroups

We divide the total set into several sub-sets (subgroups) that contain the exact same number of members. This way we know the number of total members by adding the number of total subsets.

Find the critical numbers of the function. (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE

Furkat [3]

Answer:

x = -6 and x = 4

Step-by-step explanation:

In math, the critical points of a function are the points where the derivative equals zero.

So, first we will find the derivative of the function. The derivative is:

$f'(x)=3x^2 +6x-72$

Now, we are going to make the derivative equal zero and find the answers of the equation.

$3x^2 +6x-72=0\\3(x^2 +2x-24)=0\\3(x+6)(x-4)=0\\$

So we have that the critical points are the answers to this equation:

$x+6= 0 \\x= - 6$

and

$x-4=0\\x=4$

Thus, the critical points are x=-6 and x=4

An aquarium tank holds 475 liters of water. How much is this in gallons? Use the following conversion: 1 gallon is 3.8 liters.

Mrrafil [7]

$\bf \begin{array}{ccll}
liters&gallons\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
3.8&1\\
475&g
\end{array}\implies \cfrac{3.8}{475}=\cfrac{1}{g}\implies g=\cfrac{475\cdot 1}{3.8}$
