The answer is 21
21x3=63 and 21x4=84
Area (square)=side²
therefore:
side²=200 feet²
side=√(200 feet²)=14.142 feet≈14.1 feet.
solution: side of square=14.1 feet.
Answer: $66.7
Step-by-step explanation:
Answer:The equation for inverse proportion is calculated as xy=k.
When 20 people attend the picnic, the cost for each person was $50, then k will be= 20 × 50 = 1000
Recall that k = xy
For the second aspect of the question, x= 15, k= 1000.
k= xy
y = k/x
= 1000/15
= 66.7
If 15 people attend the picnic instead, the cost per person will be $66.7

Step-by-step explanation:
So, with an equation with decimals, we can use the same method we used to clear fractions—multiply both sides of the equation by the least common denominator. Look at the decimals and think of the equivalent fractions. Notice, the LCD is 100. By multiplying by the LCD, we will clear the decimals from the equation.
