PLEASE HELP!!

Answer:

27 quarters and 37 nickels

Step-by-step explanation:

Nickels are 5¢

Quarters are 25¢

$8.60 is 172 nickels (860/5)

$8.60 is 34.4 quarters (860/25)

So then let's split it half-and-half.

425 and 435

425 would become 17 quarters.

435 would become 87 nickels.

This is still too much.

Now let's try 700 and 160.

700 would become 28 quarters

160 would become 32 nickels.

28+32=60.

This is a lot closer.

So now 27 quarters and 37 nickels. This works.

What is the simplest form of the expression? 3sqrt(24a^10b^6)?
Anastasy [175]

Answer:

\text{The simplest form is }6\sqrt6a^5b^3

Step-by-step explanation:

Given the expression 3sqrt(24a^{10}b^6).

we have to find the simplest form of the expression.

3sqrt(24a^{10}b^6)

=3(24^{\frac{1}{2}}a^{\frac{10}{2}}b^{\frac{6}{2}})

=3(24^{\frac{1}{2}}a^5b^3)

=6\sqrt6a^5b^3

which is the simplest form of the given expression.
