In getting the value of X, Y and Z in the equations X+3Y+2Z = 6 you must first substitute the variables into 0 and came up with the value of X=6, Y=2, and Z =3. So the volume of this pyramid is computed using V=1/3AH and the volume is 9. i hope you are satisfied with my answer
1.) The answer is 825.75 (multiply the given tax rates to the gross pay)
2,785 x 13% federal taxes = 362.05
2,785 x 9% state tax = 250.65
2,785 x 7.65% FICA = <u>213.05
</u> 825.75
<u>
</u>2.) The answer is 288.60 (multiply the interest rate to the balance, no need to add a late payment fee since they paid on 6/1, not after)
2,748.56 x 10.5% = 288.60
3.) The answer is 182.13 (multiply the APR to the original purchase price, no need to add the sales tax)
<u /> 1,500 x 11.75% = 182.13
4.) The answer is 371.92 (deduct the reward to the interest)
Interest : 2,975.34 x 13.5% = 401.67
Reward : 2,975.34 x 1% = <u> 29.75</u>
371.92
5.) The answer is 1,339.13 (deduct the interest to the monthly payment)
Monthly payment : 2,236.00
Monthly interest : <u> 896.87</u> [(231,450 x 4.65%) / 12 months]
<u /> 1,339.13
Hope this helps! :)
We have been given that a store manager paid $95 for an item and set the selling price at $116.85. We are asked to find the percent mark-up.
We will use percent increase formula to solve our given problem.





Therefore, the mark-up will be 23% and option 'b' is the correct choice.

Step-by-step explanation:
All radioactive isotopes decay exponentially, the mass of the isotope as a function of time (
), measured in grams, is defined by:
(1)
Where:
- Initial mass of the isotope, measured in grams.
- Decay rate, measured in
or
or
.
- Time, measured in minutes, days or years.
We define the decay rate in terms of half-life by using the following expression:
(2)
Where
is the half-life of the isotope, measured in minutes or years.
Now we proceed to determine the missing values:
a) Polonium-200 (
)


b) Lead-194 (
)


c) Iodine-125 (
)



d) Kryption-75 (
)


e) Strontium-79 (
)


f) Uranium-229 (
)


g) Plutonium-239 (
)
