The height is 22 inches? It says it in the question
First define the variables:
c = amount of children
a = amount of adults
Next create the equations to satisfy the conditions:
1) Total group is 12 people:

2) Total cost is $100 with adults costing $10 and children being $6:

-3/4 is rational because it can be written as a ratio.
Answer:
3√2
Step-by-step explanation:
In this question, we are asked to get the value of √ ( x²-y² ), while the value of x² and y² are given to be 33 and 15 respectively.
Hence, x² =33 and y² = 15.
Putting the values of x² and y² in the above expression we get,
√ ( x²-y² ) = √ ( 33-15) = √18 =3√2. (Answer)
You'll use the chart to start your equation. There are 2000 grams to a kilogram. One batch is 1425grams. To get 2 kilograms she needs 2000 grams. So 2000-1425= your answer. For question 2, there are 1000 ml in 1 Liter. Use this information to see which will hold more liquid, 2 bottles or 8 cans.
