Area= length*width
115= x * 5
115/5 = x
23 = x
So the length will be 23 cm.

A physician orders 140mg of a medication to give orally. You have 125mg/5mL on hand. What is the correct dose of medication to g
adelina 88 [10]
<h2>Hello!</h2>

The answer is: The correct dose of medication to give is 5.6 mL

<h2>Why?</h2>

To solve this problem we need to establish a relationship between the prescripted medication and the available solution.

Let's write the needed equations to establish the relantionship:

\frac{125mg}{5mL}=1\\\\125mg=5mL

The available solution means 125 mg each 5 mL of solution, so:

\frac{125mg}{5mL}=\frac{140mg}{x}\\\\x*\frac{125mg}{5mL}=140mg\\\\x=140mg*\frac{5ml}{125mg}=\frac{700mg*mL}{125mg}=5.6mL

Hence, the correct dose of medication to give is 5.6 mL of the 125 mg/5mL solution.

Have a nice day!

What is the slope of the line that goes through -3,7 &amp; -17,3
Natalka [10]

Point 1: (-3, 7)

Point 2: (-17, 3)

To find the slope, we need to use the slope formula which is as follows: m = (y2 - y1) / (x2 - x1). We will plug in each x and y coordinate from our points above, respectively.

m = (3 - 7) / (-17 - - 3)

m = (-4) / (-14)

m = 2/7

The slope of the line that goes through (-3, 7) and (-17, 3) is 2/7.

Hope this helps!! :)

If f(x) =3^x+10 and g(x) =4x -2 find (f+g)(x)
Valentin [98]

Answer:

(f+g)(x)=3^x+4x+8

if f(x)=3^x+10 and g(x)=4x-2.

Step-by-step explanation:

We are given f(x)=3^x+10 and g(x)=4x-2.

We are asked to find (f+g)(x).

(f+g)(x) means f(x)+g(x)

(f+g)(x)=(3^x+10)+(4x-2)

You only have one pair of like terms, that is the constants.

(f+g)(x)=3^x+4x+10-2

(f+g)(x)=3^x+4x+8
