We will need 85cc of 20% saline solution for the mixture

Let the amount of 20% saline solution be "a"

If a nurse mixes 40 cc of a 70% saline solution with a 20% saline solution to produce a 36% saline solution, then the finished product will be 40 + a cc which containing 36% saline solution.

The saline content will therefore be expressed as:

(70% of 40)+20% of a = 36% of (40 + a)

0.7*40 + 0.2a = 0.36(40 +a)

28 + 0.2a = 14.4+0.36a

28 - 14.4 = 0.36a - 0.2a

13.6= 0.16a

a = 13.6/0.16

a = 85

This means that we will need 85cc of 20% saline solution for the mixture

x^2 - 2x - 4

Step-by-step explanation:

g(x) - f(x) = (x^2 + 1) - (2x + 5) = x^2 + 1 - 2x -5 = x^2 -2x +(1-5) = x^2 - 2x - 4

Answer:

y = (-1/4)x + 5

Step-by-step explanation:

y = mx + b

---------------

Solve for b first

6 = (-1/4)-4 + b

6 = 1 + b

6 - 1 = b

5 = b

y = (-1/4)x + 5

Answer:

y=-1/4x+5

Step-by-step explanation:

We need b also known as y intercept

slope-intercept form: y=mx+b

plug in x and y points

and we know m or slope is -1/4

(6)= -1/4 (-4) +b

we multiplied -1/4 by -4 which gave us +1

6= 1+b

6-1=b

5=b

Now we know what b is, so

y= -1/4x + 5

Answer:-10m+10x

Step-by-step explanation: add -8m plus -2m which gives you -10m and then add 3x plus 7x which gives you 10x so the final answer is -10m+10x.

3²-5

Step-by-step explanation:

(3-2²)+5=4

3²-5=4

Answer:

D

Step-by-step explanation:

First off, lets simplify (3-2^2)+5 = -1+5 = 4

We will need to  find an expression that will equal to 4

lets try 1, 5-2^2 = 1, 1 =\ 4

Alright, lets try 2, 2^2 -5 = -1, -1=\5

Now lets try 3, 5 - 3^2 = -4, -4=\4

So by process of elimination we can say that D is correct by I will show you why it is correct. 3^2 -5 = 4, 4=4

Answer:

Compare the numbers 3.333/10 and 6/10, and that will allow you to determine which of the numbers is larger.

6 is closer to 10 on the number line than 3.33333. Thus the number that is closer to 10, is larger than the other number which is not.

So in this case it would be 6/10.

The volume in cubic inches (in^3) of a 1.5-liter bottle. is 91.53 cube inches.

Volume is a three-dimensional quantity that is used to measure the capacity of a solid shape. It means, the amount of three-dimensional space that a closed figure can occupy is measured by its volume.

Given: Volume in liter= 1.5 liter

To covert the volume from liter to inches cube

we know,

1 liter= 61.02 inch cube

So,

1.5 liter= 1.5*61.02

1.5 liter= 91.53 cube inches.

Hence, the volume in cube inches is 91.53 cube inches.
