Answer:

Explanation:

Block on the table m(A) = m1,

block on the cord m2,

the coefficient of static friction is k1=0.4,

the coefficient of kinetic friction is k2 =0.28

(a)

Block A:

T = F(fr) = k1 •N = k(s) • m1 •g,

Block B: T = m2•g.

k1 • m1 •g= m2•g,

m1 = m2/k(s) = m2/0.4.

(b)

Block A:

T = F(fr) = k2 •N = k2 • m1 •g,

Block B:

T = m2•g.

k2• m1 •g= m2•g,

m1 = m2/k2 = m2/0.28.

tax saving = tax deduction × marginal tax

Choose the preferred sentence from each pair and justify your choice. a. (1) Lindsay's request to telecommute was denied, but sh

mr_godi [17]

Answer:

(2). Although her request to telecommute was denied, Lindsay will begin a flextime schedule in two weeks.

Explanation:

The second choice would be the most preferred as it conveys the idea in a formal and precise manner. The complex sentence beginning with the subordinate clause already hints the listener that the key message is yet to come. It helps him/her in understanding the intended message without any confusion. The first sentence fails to create that specificity as it connects two independent ideas which remove the listener's focus from the main idea i.e. 'she will begin a flextime schedule in two weeks.' Thus, option (2) adopts the correct format and sentence structure to deliver the message effectively, efficiently, and precisely.

Maurinko [17]

We can find the increase in operating income for each $ 1,000 increase in revenue per month by finding the contribution margin ratio and the multiplying it with the increase operating income of $ 1,000 each.

The formula to find the contribution margin ratio is :-

Contribution margin ratio = Contribution margin per unit / Selling price per unit

= 12 / 20 = 60%

The increase in operating income = Contribution margin ratio * Revenue

= 60 % * 1,000

= $ 600

The calculations are shown below :-

Selling price per unit = $ 20

Variable cost per unit = $ 8

Contribution margin per unit = Selling price per unit - Variable cost per unit

= $ 20 - $ 8 = $ 12
