I’m not sure but i think 66 hours because both pumps must fill half of the pool which would split the timing for each which would make pump 1 take 36 hours to fill half and pump two take 30 hours to fill the rest. when you add these hours it equals 66. i hope i helped :)

If the coordinates of the endpoints of a diameter of the circle are​ known, the equation of a circle can be found.​ first, find
Alja [10]

Given

Endpoints of the diameter (5,2) and (-7,4)

Step One

Find the center

Center = (x2 + x1)/2 , (y2 + y1)/2

x2 = -7; x1 = 5; y2 = 4; y1 = 2

Center = (-7 + 5)/2 ; (4 + 2)/2;

Center = (-1 , 3)

Step Two

Find the radius squared using the distance formula. Use (5,2) as the second point. The other point is the center.

Distance squared = (5 - - 1)^2 + (2 - 3)^2

Distance squared = ( 6)^2 + (-1 )^2

Distance squared = 37

Step Three

State the circle's formula

(x - - 1 )^2 + (y - 3)^2 = 37

(x + 1)^2 + (y - 3)^2 = 37

Each of the equal sides of an isosceles triangle exceeds 3 times the base by 2 inches. If the perimeter is 60 inches, find the l
vfiekz [6]
Sides are x,x,b


x is identical side

x is bigger than 3 times b by 2
x=3b+2

p=x+x+b
60=2x+b

x=3b+2
60=2(3b+2)+b
60=6b+4+b
60=7b+4
minus 4 both sides
56=7b
divide both sides by 7
8=b

sub back
x=3b+2
x=3(8)+2
x=24+2
x=26


legnths are
26in, 26in, 8in
