Answer:

30 adult tickets and 50 child tickets

Step-by-step explanation:

605 = 8.5a + 7c

80 = a + c

620 = (8.5*40) + (7*40)

605 = (8.5*30) + (7*50)

a = 30  c = 50

Which expression is equivalent to...? Screenshots attached, please help.
BaLLatris [955]

For this case we must simplify the following expression:

\sqrt [3] {64 * a ^ 6 * b ^ 7 * c ^ 9}

We rewrite:

64 = 4 ^ 3\\a ^ 6 = (a ^ 2) ^ 3\\b ^ 6 * b = ((b ^ 2) ^ 3 * b)\\c ^ 9 = (c ^ 3) ^ 3

So:

\sqrt [3] {4 ^ 3 * (a ^ 2) ^ 3 * (b ^ 2) ^ 3 * b * (c ^ 3) ^ 3} =\\\sqrt [3] {4 * a ^ 2 * b ^ 2 * c ^ 3) ^ 3 * b} =

By definition of properties of powers and roots we have:

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

So:

4a ^ 2b ^ 2 c ^ 3 \sqrt [3] {b}

Answer:

Option B

Determine the value of each expression.<br> i11=
Basile [38]

Answer:

11 * I

Unless you can tell me what I is equal to, I can't give you a number as an answer. Just take what ever I is equal to, an multiply it by 11. If the answer choices are equations rather than numbers, than just say 11 * 1.

If the question comes with any more information, please comment so I can give you a stronger answer.

Hope this helps! :)

If you multiply two decimals less than 1 can you predict whether the product will be less than or greater than either of the fac
ki77a [65]

I predict that the product will be less than either of the factors.

When you multiply two numbers less than ' 1 ', you are
calculating the size of a piece of a piece.  It winds up being
smaller than either of the pieces.
