1.<br> A patient is told to force fluids to 3 L/day. How many mls should she drink?
Damm [24]

The patient should drink 3000 milliliter per day

<em><u>Solution:</u></em>

Given that a patient is told to force fluids to 3 liter per day

To find: Amount the patient should drink in milliliter

Use the conversion factor,

1 liter = 1000 milliliter

Now we have to find the amount the patient she drink in milliliter

Amount patient drinks in liter = 3 liter per day

Therefore, convert 3 liter to milliliter

3 liter = 1000 x 3 milliliter = 3000 milliliter

Thus the patient should drink 3000 milliliter per day

Write and solve a quadratic equation for the situation below. Choose the answer that has both an equation that correctly models
Sedbober [7]
The answer 
<span>the true answer  is A) 4x^2+52x+165=320; x = 2.5 
proof:
since </span><span>they want to limit its area to 320 in^2
x must be equal 2.5, because </span>4.(2.5)^2+52(2.5)+165= 25+130+165=320;

the main rule of the area of a triangle is 

A= (base x height )/2
let be b the base and h the height 
so h=20- 6b
so 50= b x( 20-6b) /2, implies 100/b = 20 - 6b
if b=x, we have 100= 20x -6x² this  is equivalent to 6x² - 20x = -100
so the answer is 
<span>D) None of the choices are correct.
</span>
<span>the largest dimensions that can be used for the fountain are
</span>
<span>B) x^2+8x+16=800

C) x^2+16=800
</span>
proof
x^2+8x+16=x^2+8x+4², 4² is the area of the square fountain, and x^2+8x should be the remaining of the area, t<span>he total space that the fountain and sidewalk can use is 800, it is  less than 800 ft^2.
</span>Use the same method for. x^2+16=800

The average test score of RSM students in September increased by 10%. In October it increased by another 15%. By what percent di
irina [24]

Answer:

26.5%

Step-by-step explanation:

<u>Increasing  Percentages</u>

When sequential percentages increasing are computed, each increase applies to the previous result, instead of the first quantity. That is why sometimes the final results may be confusing. For example, increasing 10% and then 15% will not be the same as increasing a total of 25%.

The average test scores of RSM students first increased by 10%. It means that some quantity C increased by

10C/100=0.1C

Now the average test scores are

C+0.1C=1.1C

A new increasing occurred by 15%, and the previous quantity must be multiplied by 1.15, so the final average test scores are

1.15(1.1C)=1.265C

It means that the total increasing was 100(1.265-1)=26.5\%
