Mathematics

lidiya [134]3 years ago
8 0

Answer:

A (in $USD) = 5,000(1 + .04/4)^4(8)

A = 5000(1 + 0.01)^32

A = 5000(1.01)^32

A = 5000(1.37494068)

A ≈ 6874.7034

<u>A = $6875 or $6875.7 (depending on rounding requirement)</u>

Step-by-step explanation:

Compound Interest Formula

A = P(1+ r/n)^n(t)

  • A is the amount in the account after t years
  • P is the principal (original amount invested)
  • r is the annual rate, expressed as a decimal
  • n the number of times the interest is calculated a year*
  • t is the number of years

*If the interest is compounded monthly n = 12, if quarterly n = 4, if daily n = 365.

A chicken salad recipe calls for 1 8
NARA [144]

Answer: 1.0625\ pounds or \frac{17}{16}\ pounds

Step-by-step explanation:

The complete exercise is: "A chicken salad recipe calls for \frac{1}{8} pound of chicken per serving . How many pounds of chicken are needed to make 8\frac{1}{2}  serving".

You can convert the Mixed number to a Decimal number. Divide the numerator 1 by the denominator 2 and then add the quotient to the Whole number. Then, you get:

8+0.5=8.5

Now divide the numerator 1 by the denominator 8 to write the fraction to a Decimal number. Then:

\frac{1}{8}= 0.125

Let be "x" the amount of pounds are needed to make 8\frac{1}{2}  serving.

Then, you can set up the following proportion:

\frac{1}{0.125}=\frac{8.5}{x}

Solving for "x", you get:

\frac{1}{0.125}=\frac{8.5}{x}\\\\x(\frac{1}{0.125})=8.5\\\\x=8.5*0.125\\\\x=1.0625

or \frac{17}{16}\ pounds

PLEASE HELP ASAP!!!!!!
statuscvo [17]

Answer:

24 sides

Step-by-step explanation:

a polygon cannot have a decimal number of sides, it is impossible

since the sum of these exterior angles in a regular polygon must equal 360 degrees. The maximum number of sides that would yield exterior angles that are integers is 360

because 360 ÷ 360 = 1.
