There are 5040 arrangements
Answer:
There are 10 boys and 6 girls in the class
Step-by-step explanation:
The given parameters are;
The number of boys = The number of girls + 4
The number of students in the class = 16
Let x represent the number of girls in the class and let y represent the number of boys in the class
Therefore;
y = x + 4...(1)
x + y = 16...(2)
Making y the subject of equation (2) gives;
y = 16 - x
Equating the values of y from equation (1) and equation (2) gives;
x + 4 = 16 - x
Which gives;
2·x = 16 - 4 = 12
x = 12/2 = 6
x = 6
The number of girls = x = 6
From equation (1), we have;
y = x + 4 = 6 + 4 = 10
y = 10
The number of boys = y = 10.
311(1.50)+.50x=385.50
would be your equation
We know that
15 1/4 acres-----------> (15*4+1)/4-----> 61/4 acres
[<span>number of lots]=(61/4)/(2/3)----> (61*3)/(4*2)---> 183/8----> 22.875
22.785-----> 22 7/8
we know that
7/8--------> multiply by 3-------> 21/24
2/3-------> multiply by 8-------> 16/24
21/24-16/24-------> 5/24
so
22 7/8 is equals to--------> 22 21/24----> 22 (16/24+5/24)
t</span><span>he maximum number of lots that can be created are 22+1-----> 23 lots
</span><span>and there is a remnant of 5/24</span>
