Question

p(a) =3/8 n(s)=16 what is n(a)​

Answer 1

$\huge\pink{\boxed{\green{\mathfrak{\overbrace{\underbrace{\fcolorbox{red}{aqua}{\underline{\pink{☆Answer☆}}}}}}}}}$

$p(a) = \frac{n(a)}{n(s)}$

$\frac{3}{8} = \frac{n(a)}{16}$

$n(a) = \frac{3 \times 16}{8}$

after cancelling,

$n(a) = 3 \times 2$

n ( a ) = 6.

hope it helps you.

Answer 2

Answer:

Correct option is A)

Let time taken to fill tank by small tap be x hours

Time taken to fill tank by big tap be y hours Then, x - y = 5 or x = 5 + y

1 Smaller tap can fill in one hour = = X

Bigger tap can fill in one hour

1 1 Then, + X y 1 6 =

(x + y)/(xy) = 1/6

xy = 6(x + y)

y(5 + y) = 6(5 + y + y)

5y + y ^ 2 = 30 + 12y

y ^ 2 - 7y - 30 =

y = (7 plus/minus sqrt(49 + 120))/2

y = (7 plus/minus 13)/2

y = 10, - 3

x=5+10=5+10=15 hours

Hence, Small tap can fill the tank in 15 hours and bigger tap can fill in 10 hours
