Answer:
$450,000.
Step-by-step explanation:
<h3>100% - 38% = 62% of the previous house value is the current house value after the 38% decrease.</h3><h3>We'll first convert 62% to a decimal by dividing by 100.</h3>
62% = 62 / 100 = 0.62
<h2>0.62x = 279,000</h2><h3>Multiply by (100/62) on each side.</h3><h2>x = 450,000</h2><h2>The house value when it was purchased was $450,000.</h2>
For example, three points are always coplanar, and if the points are distinct and non-collinear, the plane they determine is unique. However, a set of four or more distinct points will, in general, not lie in a single plane. Two lines in three-dimensional space are coplanar if there is a plane that includes them both.
The answer for your question is -3
Let,the time taken by larger pipe = x
By smaller pipe = x+5
It would be: 1/x + 1/(x+5) = 9/100
= x+5+x /(x)(x+5) = 9/100
= 2x+5 / x²+5x = 9/100
= 100(2x + 5) = 9(x² + 5x)
= 200x + 500 = 9x² + 45x
= 9x² - 155x - 500 = 0
= 9x² - 180x + 25x - 500 = 0
= 9x(x - 20) + 25(x - 20) = 0
= (9x + 25) (x - 20) = 0
= x = -25/9 or x = 20
Time can't be in negative so -25/9 is rejected.
Now,x + 5 = 20 + 5 = 25
In short, Your Larger pipe takes 20 minutes and smaller pipe takes 25 minutes
Hope this helps!
