Answer:
it would take 45 mintues
Step-by-step explanation:
3,800 - 2000 = 1,800 and 1,800 / 40 = 45.
5x+4=9 its an expression which is greater than 1 you can do almost any expression but it has to be more than one.
Hope this helps :D

Answer:
3 sqrt(10)
Step-by-step explanation:
To find the distance, we use the formula
d = sqrt( ( x2-x1)^2 + (y2-y1)^2)
= sqrt( ( 2- -1)^2 + ( -4-5)^2)
= sqrt( (2+1)^2 +(-4-5)^2)
= sqrt( 3^2 +(-9)^2)
= sqrt( 9+81)
= sqrt(90)
= sqrt ( 9*10)
3 sqrt(10)
From the first urn, since there are 10 balls and 4 of which are red then, the update in the expanssion.
P1 = 4/6 = 2/3
In the second urn, the probability of picking white is 7/15.
Pf = (2/3)(7/15) = 21/81
