A package of cookies contains 6 cookies. Each package of cookies costs $1.49. A function, f(x), is written to represent the cos

Ronch [10]

You define a function f(x) which gives the cost of buying x packages of cookies. You are asked for the domain of the function. That is, what values can x take on? x is the number of packages bought.

It makes no sense to buy a negative number of packages. It also makes no sense to buy 1/2 a package or 3/4 of a package as the store won’t sell you a fraction of a package. Try going to the store and buying half a package of oreo cookies. I doubt you’ll get very far :)

So it makes sense to buy 0, 1, 2, 3, 4, ... boxes of cookies. These are whole numbers. So the domain is the set of whole numbers. You could also write the domain like this {0, 1, 2, 3, ...} making sure to use the curly brackets as those denote a set.

Answer:

The third option

Step-by-step explanation:

First, write the equation out as 700(0.25)=x and 700-x=y (y being your final answer). 700*0.25 is 175. Now, we subtract 175 from 700. 700-175 is 525. $525 is your final answer, which makes the third option correct. Hope this helps!

Jackrabbits are capable of reaching speeds up to 40 miles per hour. How fast is this in feet per second? (Round to the nearest w

Sonja [21]

Answer:

173/3 feet per second

Step-by-step explanation:

So we know that jackrabbits can travel at 40 miles per hour, and we are trying find how fast they can travel in feet per second. To do this, we must first convert the 40 miles per hour into feet per hour:

$\frac{40mi}{1hr}*\frac{5280ft}{1mi}=\frac{211200ft}{1hr}$

So now we know that 40 miles per hour is equal to 211200 feet per hour. Now we have to convert feet per hour to feet per second. To do this, we must first find the feet per minute (60 min = 1 hr):

$\frac{211200ft}{1hr}*\frac{1hr}{60min}=\frac{211200ft}{60min}=\frac{3520ft}{1min}$

So now we know that 211200 feet per hour is equal to 3520 feet per minute. Now we have to convert feet per minute into feet per second (60 s = 1 min):

$\frac{3520ft}{1min}*\frac{1min}{60s}=\frac{3520ft}{60s}=\frac{176ft}{3s}=\frac{173}{3}ft/s$

So now we know that 3520 feet per minute is equal to 173/3 feet per second.

Since 40 miles per hour equals 211200 feet per hour which equals 3520 feet per minute which equals 173/3 feet per second, 40 miles per hour equals 173/3 feet per second.

The jackrabbits can run at 173/3 feet per second.

I hope this helps. :)
