West Company borrowed $48,000 on September 1, Year 1 from the Valley Bank. West agreed to pay interest annually at the rate of 9% per year. The note issued by West carried an 18-month term. Based on this information the amount of interest expense appearing on West's Year 1 income statement would be:

Answers

Answer:

$1,440

Step-by-step explanation:

Given:

Borrowed amount by west company from valley bank = $48,000

Interest is paid annually = 9% per year

Time period = From 1st September to 31st December

= 4 months

The note issued by West carried an 18-month term.

Therefore,

Interest expense = Principal amount × Rate × Time period

= $48,000 × 9% × (4 ÷ 12)

= $48,000 × 0.09 × (1 ÷ 3)

= $1,440

Therefore, the amount of interest expense that will be reported on West's income statement for Year 1 is $1,440.

Second angle of a triangle is 10 degree larger than first angle. Third angle is 10
larger than second angle. Find the smallest angle of the triangle.

Answers

Let’s make a equation for each angle of triangle
Angle 1 = x
Angle 2 = x+10
Angle 3 = (x+10)+10

Angle 2 and 3 are both adding to the value of angle x so angle 1 is the smallest angle of the triangle.
Hope this helped :)

Suppose that you and a friend are playing cards and decide to make a bet. If you draw three face cards, where a face card is a Jack, a Queen, or a King, in succession from a standard deck of 52 cards without replacement, you win $40. Otherwise, you pay your friend $10. What is the expected value of your bet? Round your answer to the nearest cent, if necessary.

Answers

Answer:

Step-by-step explanation:

Expected value of the bet =

P(you make the correct draw) * 40 + P(you do not make the correct draw) * (-10) =

(4/52)(4/51)(4/50) * 40 + (1 - (4/52)(4/51)(4/50)) * (-10) =

(64/132600) * 40 + (1 - 64/132600) *(-10) =

64/3315 + (132536/132600) * (-10) =

64/3315 - (132536/13260) =

64/3315 - 33134/3315 =

-33070/3315 =

-9.97586726998 =

-$9.98, rounded to the nearest cent

(i.e., the expected value of the bet is a loss of $9.98)
