We know that the ration/percentage that brass is made of remains the same no matter what the weight is; 

Therefore, 48 ounces are 80% of the trumpet. 

48/80= 0.6 ounce per percent of the zinc (I divided the weight by the percent) 

0.6 ounces × 20%= 12 ounces 

Therefore, there are 12 ouches of zinc in Henri's trumpet. 

Hope I helped :)

Simplify the expression.<br> (x 3/2)6
Sliva [168]

For this case we must simplify the following expression:

(x ^ {\frac {3} {2}}) ^ 6

We have that by definition of properties of powers that is fulfilled:

(a ^ n) ^ m = a ^ {n * m}

Then, rewriting the expression:

x ^ {\frac {3 * 6} {2}} =\\x ^ {\frac {18} {2}} =\\x ^ 9

Answer:

(x^{\frac{3}{2}})^6=x^9

Find the measure of each interior angle of a regular octagon. (A regular polygon is one that has all the same sides and angles).
NemiM [27]

The interior angle of a regular octagon is 135 degrees.

<h3>What is an octagon?</h3>

An octagon is a polygon that has 8 sides. Therefore, a regular octagon is a octagon with all it sides and angles equal to each other.

Therefore, the sum of angles in an octagon is each interior angle multiply by the number of sides.

Therefore,

n = number of sides = 8

Hence,

interior angle = (n - 2)180 / n

interior angle = (8 - 2)180 / 8

interior angle = 6 × 180 / 8

interior angle = 1080 / 8 = 135°
