Answer:

53 sweets.

Step-by-step explanation:

The mean out of 10 bags of sweets is 42. That means that all the numbers of sweets added up would be 420.

39 + 40(2) + 41(5) + 43 + x = 420

39 + 80 + 205 + 43 + x = 420

367 + x = 420

x = 53.

So, in the 10th bag, there are 53 sweets and a sugar high for whoever eats that many sweets.

Hope this helps!

What is the square root of 180x^9y^16 in simplest form?

Answers

\sqrt{180x ^{9y ^(16) } }

Apply radical  rule :

\sqrt[n]{ab} = \sqrt[n]{a} \sqrt[n]{b}

√(180) \sqrt{x ^{9y^(16) } }

Break  the number  to its primes : 180 : 2^2*3^2*5

√(2^2*3^2*5)

Apply radical  rule :

\sqrt[n]{ab} = \sqrt[n]{a} \sqrt[n]{b}

√(5) √(2^2) √(3^2)

Apply radical  rule :

\sqrt[n]{a^n} =a

√(2^2) =2

2* √(5) √(3^2)

Apply radical  rule :

\sqrt[n]{a^n} =a

√(3^2) =3

= 2*3* √(5)

Refine:

√(5) *6

√(5) *6 \sqrt{x ^{9y ^(16) } }

Apply radical rule : 

\sqrt[n]{a^m} = a (m)/(n)

\sqrt{x ^{9y ^(16) } } = x (9y ^(16) )/(2)

= √(5) *6x (9y ^(16) )/(2)

hope this helps!
