Given:
weight of mixture : 1792 ounces
output of mixture : 560 bars of soap
to get the weight per unit, we simply divide by total weight by the total number of output.
1792 oz / 560 bars = 3.2 ounces per bar.
Answer:
AC ≈ 10.3
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan48° =
=
=
( multiply both sides by 9.3 )
9.3 × tan48° = AC , then
AC ≈ 10.3 ( to 3 sf )
