Anu drinks 2 cups of water each day. Jan drinks twice as much water as Anu.How many fluid ounces does Jan drink?

2 answers:

8 0

Simple,

first find out how many fluid ounces there are in 1 cup

1 cup=8 fluid ounces

That means for Anu:

2*8=16

Anu has drunk 16 fluid ounces.

Now, Jan, we know that she drinks 2x (twice) as much as Anu...

So,

4 cups:

4*8=32

Thus, it means that Jan has drunk 32 fluid ounces.

You would have to first find out how many fluid ounces are in on cup and there are 8. then you have to times 8 by 2 and you get how much anu drinks and that is 16 and then you have to times 16 by 2 to get jens

While testing a new pesticide, an agricultural scientist uses two functions to predict the yields of two same-sized potato farms

Pepsi [2]

Answer:

A. h(x)= -5.86x^2 + 23.37x + 34

Step-by-step explanation:

If the scientist uses the same amount of pesticide on the two farms then the x's of the functions are the same.

Then, the combined yield $h(x)$ of the two farms is just the yield of the first farm plus the yield of the second farm:

$h(x)=f(x)+g(x)$ .

Now, since

$f(x)= -2.43x^2+10.37x+9$

and

$g(x)= -3.43x^2+13x+25$ ,

then

$h(x)= (-2.43x^2+10.37x+9)+(-3.43x^2+13x+25)$

we add the coefficients of the corresponding terms to get:

$h(x)= (-2.43x^2-3.43x^2)+(10.37x+13x)+(9+25)$

$\boxed {h(x)=-5.86 x^2 + 23.37 x + 34.}$

Which is choice A.

Which of the following is the solution to the following systems of inequalities? (picture included)

Ymorist [56]

Answer:

C. (see the attachment)

Step-by-step explanation:

Both inequalities include the "or equal to" case, so both boundary lines will be solid. That excludes choices A and D.

The first inequality is plotted the same way in all graphs, so we must look at the second inequality. The relationship of y and the comparison symbol is ...

-y ≥ (something)

If we multiply by -1, we get ...

y ≤ (something else)

This means the solution space will be on or below (less than or equal to) the boundary line. This is the shaded area in graph C. (Graph B shows shading above the line.)

___

Further comment

Since the boundary for the second inequality is fairly steep, "above" and "below" the line can be difficult to see. Rather, you can consider the relationship of x to the comparison symbol. For the second inequality, that is ...

x ≥ (something)

indicating the solution space is on or to the right of the boundary line.

using d=rt you can set up 2 equations

48=(r+3)t
30= (r-3)t
solving these both for t and setting them equal warrants

48/(r+3) = 30/(r-3)
and with cross multiplication and distribution you get

48r-144=30r+90

solving for r you get r=13

Find g(32) for g(x) = x+4−−−−√. A. 3 B. 5 C. 6 D. 10

Citrus2011 [14]

Answer:

Step-by-step explanation:

I presume you meant

$g(x) = \sqrt{x + 32} \\ g(32) = \sqrt{32 + 4} \\ g(32) = \sqrt{36} \\ g(32) = 6$
