A dialysis unit requires 75000 mL of distilled water. How many gallons of water are needed?

Mathematics

Soloha48 [4]4 years ago

Answer: 19.81 gallons

Step-by-step explanation:

Given : A dialysis unit requires 75000 mL of distilled water.

We know that 1 gallon= 4 quarts

and 1 quart= 946.353 ml

Then, 1 gallon = 4\times946.353=3785.412 milliliter.

Using Unitary method ,

\text{1 milliliter = }\dfrac{1}{3785.412}\text{ gallon}

Then, \text{75000 milliliters = }\dfrac{75000}{3785.412}\text{ gallon}

=19.8129132643\approx19.81\text{ gallons}

Hence, 19.81 gallons water is needed.

8 miles in 0.5 hour what rate in miles per hour
yan [13]
In this question it is already given that a person travels 8 miles in 0.5 hours. This is enough information to get to the required answer. Let us first write down all the information's that are already given in the question.
In 0.5 hours the person covers a distance = 8 miles
Then
In 1 hour the person covers a distance of = 8/0.5 miles
                                                                   = 16 miles
So the speed of the person in miles per hour = 16/1 miles/hour
                                                                         = 16 miles per hour

The sin A is equal to 12/13 and the tan (A) is equal to 12/5.

<h3>RIGHT TRIANGLE</h3>

A triangle is classified as a right triangle when it presents one of your angles equal to 90º.  The greatest side of a right triangle is called hypotenuse. And, the other two sides are called cathetus or legs.

The math tools applied for finding angles or sides in a right triangle are the trigonometric ratios or the Pythagorean Theorem.

The Pythagorean Theorem says: hypotenuse^2=(leg_1)^2+(leg_2)^2. And the main trigonometric ratios are:

sin(\beta )= \frac{opposite\;leg}{hypotenuse} \\ \\ cos(\beta )= \frac{adjacent\;leg}{hypotenuse} \\ \\ tan(\beta )= \frac{opposite\;leg}{adjacent\;leg} \\ \\

The question gives cos (A)=5/13. If cos (A) is represented by the quotient between the adjacent leg and the hypotenuse, you have:

adjacent leg=5

hypotenuse=13

Therefore, you can find the opposite leg of A from Pythagorean Theorem, see below.

hypotenuse^2=(leg_1)^2+(leg_2)^2\\ \\ 13^2=5^2+(leg_2)^2\\ \\ 169=25+(leg_2)^2\\ \\ 144=(leg_2)^2\\ \\ leg_2=12

Thus, the opposite leg is equal to 12. Now, you can find sin (A) since:

sin(A)= \frac{opposite\;leg}{hypotenuse}=\frac{12}{13}

Finally, you can find the tan (A) since:

tan(a )= \frac{opposite\;leg}{adjacent\;leg}=\frac{12}{5}

Anybody know geometry?
Rudik [331]

hi as a person who is taking geometry, i think i can help

Answer:

7x-3=5x+1 ->x=2

Step-by-step explanation:

to find the x, you would put both equations together like how it is shown above, then try and get x to one side

7x-3=5x+1

   +3      +3

7x=5x+4

-5x -5x

2x=4

/2   /2

x=2

HELPPPP PLSSSSSSSSSSSSSSS
Alexus [3.1K]

Answer:

1.67 meters!

Step-by-step explanation:

First, we can start out by converting centimeters to meters. There are 100 centimeters in a meter, therefore to convert centimeters to meters we divide by 100. 17/100=0.17. Then, to figure out how tall Felicidad was last year, we must work backward, and subtract (because when you grow, you add). 1.84 meters- 0.17 meters= 1.67 meters!

Hope this helped!
