Answer:
let the time be "x" minutes for both
after x minutes,
the first pool will have 1660l + 30.75x
and the second pool will have 1900+ 23.25x
note: both pool Will have equal volume of water
1660+ 30.75x=1900+23.25x
30.75x-23.25x= 1900-1660
7.5x=240
x = 240/7.5
x= 40minutes
Answer:
Step-by-step explanation:
y=-1/2 x+4
For 1 the equation of the parabola is y = x^2 - 8x + 3
For 2 the equation of the parabola is y = -2x^2 - 3x + 1
For 3 the equation of the parabola is y = -x^2 + 5x - 4
You just add all the numbers together:
3 1/8+ 4 1/2+ 4 1/4
=25/8+9/2+17/4
=25/8+36/8+34/8
=95/8
=11 7/8
Ugh.. did you type in the numbers correctly? My guess would be it was meant to be B tho :)
Option( c ) is the correct one.
-2x +y= -3
x= (3+y)/2
By executing the value in second equation
{-(3+y)/2} +2y =3
( -3-y +4y)/2 =3
-3 +3y =6
3y = 9
y = 3
Again by substituting the value of y in any of the equation
-2x +y =-3
-2x =-6
x= 3.
