Step-by-step explanation:
we multiply both sides by the denominator on the right to eliminate fraction, so we have..
p*(n+a)= (n²+a/n+a)*n+a
so we have
p(n+a)= n²+a
so opening the bracket on the left hand side we have,
p*n+p*a
pn+pa
so,
pn+pa= n²+a
so collecting like terms we have,
pn-n²= a-pa
so removing a from the equation on the right hand side we have,
pn-n²=a(1-p)
dividing both sides by the equation in the bracket on the right hand side, we have..
pn-n²/(1-p)= a
a = pn-n²/1-p
or
a = n(p-n)/1-p
88.32 should be the answer. I don't know if you are supposed to round your answer though. If you are you should be able to figure that out :)
Answer:
C is the right answer.
2y x 4 = 8y
2 x 4y = 8y
Let me know if this helps!
Step-by-step explanation:
Since we have given that
Total number of members in a sports club = 38
Number of women in the club = 14
Number of women play tennis =10
Number of men play tennis = 8
Since they all play either squash or tennis.
Total number of men in the club is given by
So, number of men playing squash is given by
Number of women playing squash is given by
so, the table is shown below :
Men Women Total
Tennis 16 4 20
Squash 8 10 18
Total 24 14 38
So if you move the decimal 1 place its 1,450 the percent on the sail boat is 45% so you will times 1,450 by 4.5 making the amount put on the sailboat 6,525
