Let x = length of the park
Let y = width of the park
Because the area is 392392 ft², therefore
xy = 392392 (1)
Because three sides of fencing measure 5656 ft, therefore
2x + y = 5656 (2)
That is
y = 5656 - 2x (3)
Substitute (3) into (1).
x(5656 - 2x) = 392392
5656x - 2x² = 392392
2x² -5656x + 392392 = 0
x² - 2828x + 196196 = 0
Solve with the quadratic formula.
x = (1/2)*[2828 +/- √(2828² - 4*196196)]
= 2756.83 or 71.17
Answer:
The possible dimensions are 2756.8 ft and 71.2 ft (nearest tenth)
Percentage of all the people in the company are under the age of 25=x
We have to use the weighted average.
x=(Σwi * vi )/<span><span>Σ</span> </span><span>wi
w₁=3
w₂=2
v₁=40%
v₂=10%
</span>x=[3(40%)+2(25%)] / (3+2)=34%
Solution: 34% of all people in the company are under the age of 25.
Answer:
the answer would be 2(3-x)
Step-by-step explanation:
x would be the number that is given and since it says twice than 2 would be outside the parenthesis since the main equation would be inside the parenthesis
