Mathematics

lesya [120]2 years ago
3 0

Answer:

$20,960

Step-by-step explanation:

Use the formula for amount after simple interest  A = P(1 + rt)

"A" is the final amount

"P" is principal, or starting amount

"r" is the interest rate as a decimal

"t" is the time in years

We finding "A".

P = 8000

r = 9%/100 = 0.09

t = 18

<u>Substitute</u> the values into the formula, then <u>solve</u> to get the final answer.

A = P(1 + rt)                  

A = 8,000(1 + (0.09)(18))

Remember to follow <u>BEDMAS</u> order when solving. Solve brackets first.

A = 8,000(1 + (0.09)(18))          Multiply in brackets.

A = 8,000(1 + 1.62)             Add in brackets.

A = 8,000(2.62)                Multiply

A = 20,960                 Answer

Therefore Melissa's college fund account will have a total amount of $20,960.

Simplify the expression. 12x^-6 y^10 times 3x^7 y
Vlada [557]

We need to simplify the expression:

12x^{-6}y^{10} \times (3x^{7}y)

Now, we know that we can resolve the exponents of the variables with the like terms only and we can multiply the coefficients independently:

Now,  

12x^{-6}y^{10} \times 3x^{7}y=(12 \times 3)\times (x^{-6}\times x^{7})\times (y^{10}\times y)

On simplifying the above expression we get:

36\times x^{(-6+7)}\times y^{(10+1)}

=36 \times x^{1}\times y^{11}

=36 \times x \times y^{11}

=36xy^{11}

So the simplified form of the expression 12x^{-6}y^{10} \times 3x^{7}y=36xy^{11}.

Considering the expression x/2 + y2. Which statements are true?Mark all that apply.
Svet_ta [14]

Answer:

  D.  8/2 +(-10)² = 104

Step-by-step explanation:

To find which statements are true, evaluate the expression for the given variable values. You do this by putting the numbers in place of the respective variables, then doing the arithmetic.

The respective expression values are ...

  A 83 ≠ 37 . . . . (4/2) +9² = 2 +81 = 83

  B 31 ≠ 61

  C 52 ≠ 61

  D 104 =104 . . . . true statement

__

I find it less tedious to write a function into a calculator or spreadsheet and let it do the repetitive math. Examples of the calculation are shown above.
