Mnenie [13.5K]

Answer:

\boxed{\bf\: The  \: park  \: sold  \boxed{ 34{}} \: child  \: tickets.}

Step-by-step explanation:

<u>Given:</u>

Percentage of Tickets sold at a water park - 68%

The Number of Tickets if the park sold in all - 50

<u>To </u><u>Find:</u>

The Number of child tickets the park sold.

<u>Solution:</u>

We know that 68% equals to 68/100.

Step 1: Multiply 68/100 by 50 which is the number of tickets the park sold :-

\sf \:  =  \:  \cfrac{68}{100}  \times 50

<u>Note</u>:The Simplified form of 68/100 * 50 would be the answer to this question.

Step 2: <u>Cancel One zero of 50 and one zero of 100,That is</u>:-

\sf =  \cfrac{68}{ 10\cancel0}  \times 5 \cancel0

<em>Results to,</em>

\sf  = \cfrac{68}{10}  \times 5

Step 3: <u>Cancel 5 and 10, That is</u>:-

\sf  = \cfrac{68}{ \cancel{10 }}  \times  \cancel5

<em>Results to,</em>

\sf =\:  \cfrac{68}{2}  \times 1

\sf = \cfrac{68}{2}

Step 4: <u>Cancel 68 and 2, That is</u>:-

\sf =\:  \cfrac{ \cancel{68}}{ \cancel2}

<em>Results to,</em>

\sf  =  \cfrac{34}{1}

\sf  = 34

34 is the result.

Hence,

\underline{ \rm \: The  \: park  \: sold  \: \bold{ 34 } \: child  \: tickets.}

Ella has 0.5 lbs of sugar. How much water should she add to make the following concentrations? Tell Ella how much syrup she will
HACTEHA [7]

Ella has to add 32.833 lbs of water to get 33.333 lbs of syrup.

<u>Solution:</u>

Ella has 0.5 lbs of sugar. Let x lbs be the amount of water Ella should add to get the 1.5% of syrup,

\Rightarrow0.5\text{ lbs }- 1.5\%

\Rightarrow x+0.5\text{ lbs }- 100\%

On writing the proportion,

\Rightarrow\dfrac{0.5}{x+0.5}=\dfrac{1.5}{100}\\ \\\Rightarrow0.5\cdot 100=(x+0.5)\cdot 1.5\\ \\\Rightarrow50=1.5x+0.75\\ \\\Rightarrow1.5x=50-0.75\\ \\\Rightarrow1.5x=49.25\\ \\\Rightarrow x=\dfrac{49.25}{1.5}\approx 32.833\ lbs

To get 1.5% syrup Ella should add 32.833 lbs of water. The total weight of syrup is 33.333 lbs.
