A shoe dealer purchased net Birr 8,000 worth of shoes from a shoe company.
Alex787 [66]

Answer:

Step-by-step explanation:

A) The dealer bought Birr 8000 at 7% tax.

Total amount to be paid = cost price (1 + r%)

r = 7% = 0.07

Total amount to be paid = 8000 \times 1.07 =\texttt {Birr}  \ \  {8,560}

B) To find the VAT, it is the difference between the tax paid when the good was bought and the tax put on it after it was sold.

Tax paid when the shoes were bought = 7% of cost price

= 7 \%  \times  8,000 = \texttt {Birr} \ 560

Tax paid when the shoes were sold = 9% of selling price

= 9 \% \times 12,000 = \texttt {Birr} \ 1,080

VAT = tax recovered on sale - Tax paid on purchase

\texttt {VAT} = 1080 - 560 = \texttt {Birr}\ 520

A large mixing tank initially contains 1000 gallons of water in which 40 pounds of salt have been dissolved. Another brine solut
sergey [27]

Answer:

If A(t) represents the amount of salt in the tank at time t, the correct differential equation for A is is dA/dt =  15 - 0.005A

Option C) dA/dt =  15 - 0.005A is the correction Answer

Step-by-step explanation:

Given the data in the question;

If A(t) represents the amount of salt in the tank at time t, the correct differential equation for A is?

dA/dt = rate in - rate out

first we determine the rate in and rate out;

rate in = 3pound/gallon × 5gallons/min = 15 pound/min

rate out = A pounds/1000gallons × 5gallons/min  = 5Ag/1000pounds/min

= 0.005A pounds/min

so we substitute

dA/dt = rate in - rate out

dA/dt =  15 - 0.005A

Therefore, If A(t) represents the amount of salt in the tank at time t, the correct differential equation for A is is dA/dt =  15 - 0.005A

Option C) dA/dt =  15 - 0.005A is the correction Answer

Write the equation of the line that passes through the points (-6,8)(−6,8) and (8,8)(8,8). Put your answer in fully reduced poin
Artemon [7]

Answer:

y=8

Step-by-step explanation:

Point slope is y2-y1 over x2-x1

So its 8-(-6)  over 8-8 which equals 14/0 which means the equation of the line is y=8

This is a horizontal line on 8 on the y axis

The difference of sample means of two populations is 108.7, and the standard deviation of the difference in sample means is 32.
charle [14.2K]

Answer: A. The difference of the two means is significant at the 68% confidence level, so the null hypothesis must be rejected.

Step-by-step explanation:

I just got it right on PLATO, so I know it’s 100% correct.
