marissa [1.9K]

Answer:

22Ω

Explanation:

Given parameters:

Potential difference = 3.3V

Current = 0.15A

Unknown:

Resistance = ?

Solution:

According to ohm's law, potential difference, current and resistance are related by the expression below;

V = I R

where V is the voltage

I is the current

R is the resistance

3.3 = 0.15 x R

R = $\frac{3.3}{0.15}$ = 22Ω

Marigold, Inc. uses activity-based costing as the basis for information to set prices for its six lines of seasonal coats.

agasfer [191]

Answer:

Designing= $42 per designer hour

Sizing and cutting= $26.85 per machine hour

Stitching and trimming= $17.75 per labor hour

Wrapping and packing= $10.5 finished unit

Explanation:

<u>To calculate the activity-based overhead rates, we need to use the following formula:</u>

Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base

Designing= 445,200/10,600= $42 per designer hour

Sizing and cutting= 4,081,200/152,000= $26.85 per machine hour

Stitching and trimming= 1,491,000/84,000= $17.75 per labor hour

Wrapping and packing= 346,500/33,000= $10.5 finished unit
