2.5 c =<br> fl oz<br> Cups of water for your thirsty dog and cat
inn [45]

Answer:

20 fluid ounces

Step-by-step explanation:

Each cup contains 8 fl oz. This means that if you multiply 2.5 times 8, you get 20.

If you want to break it down more, you can multiply the 2 * 8, then multiply the .5 * 8. Then add the answers together. So.... you get 16 + 4 = 20 fl oz.

If r(x) = 2 – x2 and w(x) = x – 2, what is the range of (w circle r) (x)?
VashaNatasha [74]

Answer:

(-\infty, 0)

Step-by-step explanation:

(w circle r) (x) is the composite function(w of r(x)), that is, w(r(x))[/tex]

We have that:

r(x) = 2 - x^{2}

w(x) = x - 2

Composite function:

w(r(x)) = w(2 - x^{2}} = 2 - x^{2} - 2 = -x^{2}

-x^{2} is a negative parabola with vertex at the original.

So the range(the values that y assumes), is:

(-\infty, 0)

Plz help its due tonight <br><br> thanks a lot
kicyunya [14]

x + y = 14 \\ 340x + 1030y = 8210
x = 14 - y
Substitute into
340(14 - y) + 1030y  = 8210 \\ 4760 - 340y + 1030y = 8210 \\  690y = 3450 \\ y = 5
Insert y = 5 into
x = 14 - 5 \\ x = 9
