Mathematics

AnnyKZ [126]3 years ago
6 0

Answer:

  Rachel is not correct

Step-by-step explanation:

It is true that the set of integers includes negative numbers, where the sets of whole or natural numbers do not. However, any rational, irrational, or real number can be negative. -5.5 is a rational number, but <em>it is not an integer, because it has a fractional part</em>.

How long will it take to administer 1000 cc at a drop factor of 15 drop/ml and a drip rate of 50 drop/min
gayaneshka [121]
First, we are going to determine the number of drops that needs to be administered by dividing the total volume by the volume per drop. Since, 1 cc (cm³) is equal to 1 mL then, 1000 cc is equal to 1000 mL.

   n = (1000 mL)(15 drop/1 mL) = 15000 drops

Then, divide the number of drops by the number of drops per minute.

   N = (15000 drops)/ (50 drop/min) = 300 mins

Answer: 300 mins or 5 hours

What is the value of 2/3^-4
Reptile [31]

Answer:

\frac{16}{49}

Step-by-step explanation:

To solve problems like this, we need to multiply the base ,\frac{2}{3} , the amount of times as the exponent, 4.

Essentially, the equation is \frac{2}{3} x \frac{2}{3}  x \frac{2}{3}  x \frac{2}{3} .

The product would be \frac{16}{49}.

Now we can't forget that the exponent is a negative. But because the exponent is an even number, we don't need to worry about that.

Hope this helped :)

Answer:

x= 70

Step-by-step explanation:

In this question you have to use BODMAS. This indicates that you have to do the equation in the brackets first. Therefore, 3x15= 45. Then you add 25, which will give you 70.

Solve for x: 6x – 8y = 12
Tcecarenko [31]

Hi there!


Since we have 2 variables in the given equation, and you only want to solve for one, the other will end up in your answer.


6x + 8y = 12


Step 1) Add 8y to both sides.


6x - 8y + 8y = 12 + 8y 6x = 8y + 12


Step 2) Divide both sides by 6.


\frac{6x}{6} =  \frac{8y + 12}{6}


x =  \frac{4}{3} y + 2


Final Answer -


x =  \frac{4}{3} y + 2


Hope this helps! :D
