Your 2500 gallon pool has sprung a leak and loses 70% of its water every 10 minutes . how much water will remain in the pool after 30 minutes . what is the equation and answer

equation :water remaining in pool after 30 mins= 0.027X

answer = 67.5 Gallon

Step-by-step explanation:

Given

quantity of water in pool = 2500 gallon

percentage of water lost every 10 mins = 70%

therefore percentage of water remaining in pool = (100- 70)% = 30%

Let the quantity of water in pool be X gallon

% of water remaining in gallon after 10 mins = 30% of X = 0.3X

% of water  remaining in gallon after another 10 mins = 30% of water at 10 mins = 30% of 0.3 X = 0.3 * 0.3X = 0.09 X

% of water  remaining in gallon after another 30 mins = 30% of water present at 20 minutes = 30% of 0.09 X = 0.3 * 0.09X = 0.027X

Therefore equation of water remaining after 30 mins is = 0.027 X

Substituting value of initial quantity of water in the above equation we get the volume pf water remaining in pool after 30 mins = 0.027 * 2500

                                                                                       = 67.5 gallons

step-by-step explanation:

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
