1. Find the Least Common Denominator (LCD) of \frac{2}{5} , \frac{1}{2}
Method 1: By Listing Multiples<span>List out all multiples of each denominator, and find the first common one.

5: 5,10
2: 2, 4, 6, 8,10</span>

Method 2: By Prime FactorsList all prime factors of each denominator, and find the union of these primes.

5 : 5
2 : 2
Therefore, the LCD is 2 x 5 = 10
 2. Make the denominators the same as the LCD

\frac{2 * 2}{5 * 2} + \frac{1 * 5}{2 * 5}

3. Simplify. Denominators are now the same

\frac{4}{10} + \frac{5}{10}

4. Join the denominators

\frac{4+5}{10}

5. <span>Simplify

</span>\frac{9}{10}

<span>Done (Fact: Decimal Form 0.9)</span>

To mix plaster for a dental model, 35 mL of water is used for 100g of plaster. How many mL of water should be used for 250g of p
laila [671]

Okay, here we have this:

Considering the provided information, we are going to calculate the requested value, so we obtain the following rule of three:

\begin{gathered} \frac{x}{35mL\text{ of water}}=\frac{250g\text{ of plaster}}{100g\text{ of plaster}} \\ x=\frac{250g\text{ of plaster}}{100g\text{ of plaster}}\cdot35mL\text{ of water} \end{gathered}

Solving for x:

\begin{gathered} x=2.5\cdot35mL\text{ of water} \\ x=87.5mL\text{ of water} \end{gathered}

Finally we obtain that 87.5mL of water should be used for 250g of plaster.

Write these series with summation notation. 1,4,9,16...
maksim [4K]

Answer:  \sum\limits_{i=1}^{n} n^2 , where n is a natural number.

Step-by-step explanation:

A series can be represented in a summation or sigma notation.

Greek capital letter, ∑ (sigma), is used to represent the sum.

For example: \sum\limits_{n=1}^{\infty} n=1+2+3+4+5+..., where n is a natural number.

The given series : 1,4,9,16 which can be written as 1^2, 2^2, 3^2,... .

So , we can write it as

\sum\limits_{n=1}^{\infty} n^2 , where n is a natural number.
