Answer:
a. radius = 0.0006m = 0.6mm and length =0.393m = 393mm
b. frequency =377.86Hz
Explanation:
Given:
mass of steel= 4g = 0.004kg
density of steel = 7890kg/m3
tensile stress of steel 7.0x10⁸
tension load =900N
from the density, we will calculate for the Volume of the steel string
density = mass/volume
volume = mass/density = 0.004/7890 = 5.07 x 10⁻⁷ m³
from the tensile stress will can get the maximum base Area of the string ,
tensile stress = load/area =
7x10⁸ = 900/A
A = 900/7x10⁸ = 1.29x10⁻⁶ m²
Area = πr²
area/pi = 4.105x10-7
radius = 0.0006m = 0.6mm
volume = Area x length
length = vol/area =(5.07 x 10⁻⁷ m³)/1.29x10⁻⁶ m² = 0.393m
b. the highest possible frequency is given by:
F = 
where T= tension, m=mass, L=length
F = 
= 297.04/0.786
frequency =377.86Hz
Answer:
The contribution margin per unit is $7
Explanation:
The contribution margin per unit can be defined as the difference between the selling price per unit and the variable cost per unit.
Contribution margin per unit = Selling price - Variable cost
Contribution margin per unit = $12 - $5
Contribution margin per unit = $7
The contribution margin per unit is $7
Answer:
c. Debit to Bank Credit Card Sales, debit to Credit Card Expense, and a credit to Sales
Explanation:
The journal entry is shown below:
Bank credit card sales A/c Dr XXXXX
Credit card expense A/c Dr XXXXX
To Sales A/c XXXXX
(Being the sales is recorded via bank credit cards)
As the credit card has some expense so we debited the credit card expense along with the bank credit card sales and credited the sales as it is revenue which is to be credited
Answer:
There are several ways to compute the degree of operating leverage (DOL). A fairly intuitive approach is expressed below.
DOL = (sales - variable costs) / (sales - variable costs - fixed costs)
For Kendall, the DOL is computed as follows:
DOL = (1,000 * $60 - 1,000 * $60 * .30) / (1,000 * $60 - 1,000 * $60 * .30 - $30,000) = 3.5

Answer:
B. inform her divisional merchandiser manager of the proposal
Explanation:
Since in the question it is mentioned that the Janine buys from each season also she knows that this thing would become benefiical what European tourists are wearing and applying this in an assortment for the customers that are targeted
So before discussion with the vendor first she reports the divisional merchandiser manager regarding this proposal
