Answer:

Jack has to sell the old computers worth $8000

Step-by-step explanation:

Jack is paid for selling used computers = $15 per hour plus 5% commission

Let the revenue generated from selling the computers by him = $x

He will be paid for 40 hours = $(40×15) = $600

Commission earned by selling x computers = $0.05x

Total amount earned by him in 40 hours week = 600 + 0.05x

If this amount is $1000,

$1000 = $(600 + 0.05x)

0.05x = 1000 - 600

0.05x = 400

x = \frac{400}{0.05}

x = $8000

Therefore, Jack has to sell the old computers worth $8000.

The frequency (f) of the note produced by striking a pipe of length (L) and radius (r) is given by f = 2r + c over 2L where c is
Luba_88 [7]

Now the aim of the above discussion is to internalize the mathematical relationships for open-end air columns in order to perform calculations predicting the length of air column required to produce a given natural frequency. And conversely, calculations can be performed to predict the natural frequencies produced by a known length of air column. Each of these calculations requires knowledge of the speed of a wave in air (which is approximately 340 m/s at room temperatures). The graphic below depicts the relationships between the key variables in such calculations. These relationships will be used to assist in the solution to problems involving standing waves in musical instruments.

Springfield nuclear energy inc bonds are currently trading at 283.30. The bonds have a face value of $1,000, a coupon rate of 2%
vampirchik [111]

<u>Answer:</u>

The yield to maturity of the bonds is 11%

<u>Explanation:</u>

Price at which the bonds is currently trading = 283.30$

Face Value = $1000

Coupon rate = 2%

Hence the coupon bond rate = $1000 ×2%

= 1000\times \frac{2}{100}

=$20

Years to maturity: 20 years

Formula used:  

=\frac{(C+ (\frac{(F-P)}{n}))}{(\frac{(F+P)}{2})}

Where C is the bond coupon rate

F is the face value

P is the price

N is the number of years

=\frac{(20 +(\frac{(1000-283.30)}{20})}{(\frac{(1000+283.30)}{2})}

=11%

The yield to maturity of the bonds is 11%
