Answer:
<em>24 children</em>
Step-by-step explanation:
If the length of time, y hours, it takes to put a jigsaw puzzle together is inversely proportional to the number of children, x, this is represented as;
k is the constant of proportionality
If it takes 16 children 6 hours to put the jigsaw puzzle together, this means at x = 16, y = 6
Substitute:
6 = k/16
k = 6*16
k = 96
W are to find number of children needed to put the same jigsaw puzzle together in 4 hours, this is done by substituting k = 96 and y = 4 into the expression y = k/x
y = 96/4
y = 24
<em>Hence it will take 24 children to put the same jigsaw puzzle together in 4 hours</em>

Alexandra makes a pattern she uses 2 square for every 3 triangles in the pattern , how many triangles will Alexandra uses if the pattern has 18 square?
He will pay the 10% of $7200, and that is calculated like so:
(10%)(7200)
= (10/100)(7200)
= (1/10)(7200)
= 720
therefore he will pay $720
Step-by-step explanation:
To find the slope between two given points you use the equation:
(8,10) are 
(16,24) are 
After that you just plug in:

If the probability that she will be picked is 2/38 = 1/19
then the probability that she won't be picked is 36/38 = 18/19
