Answer:

First blank has the value r.

Second blank has the value 2

Step-by-step explanation:

The given equation on the left side is ( r- s)^{2}

Now,<u> ALGEBRAIC IDENTITY </u>states that

( a- b)^{2} = a^{2}  + b^{2} -  2 \times a \times b

Here, comparing a = r and b = s, we get

( r- s)^{2} = r^{2}  + s^{2} -  2 \times r \times s

So, the first blank has the value r.

Second blank has the value 2

If you put $25 each month into a savings account that paid a simple interest rate of 6.5% each year, how much would you have in
DochEvi [55]

Answer:

$339.00

Step-by-step explanation:

If you put $25 each month into a savings account that paid a simple interest rate of 6.5% each year, how much would you have in your account at the end of two years?

We solve the above question using the Equation:

A = P(1 + rt)

P = Principal = Amount deposited each month = $25

The amount deposited in a year = $25 × 12 months = 300

Calculation:

First, converting R percent to r a decimal

r = R/100 = 6.5%/100 = 0.065 per year.

Solving our equation:

A = 300(1 + (0.065 × 2)) = 339

A = $339.00

Therefore, you would have $339 in your account after 2 years

Michael bought 0.44 pound of sliced turkey. What is the value of the digit in the hundredths place?
slega [8]
<span>Michael bought 0.44 pound of sliced turkey.
Now, we need to find what digit is in the value of hundredths.
Note, that the place value is hundredths with ths. Thus, the value is in the decimal points.
And the value that Michael bought is a decimal number as well.
Not, let us find the value of hundredths.
=> 0.44 pounds
=> .4 = tenths
=> 0.04 = hundredths.
Thus the value of hundredths is 4 or 0.04 or 4/100 in fraction form.

the result of an experiment was 117.755 particles per milliliter. write the decimal as a mixed number.
nordsb [41]

The result of experiment in mixed fraction form is 117\frac{151}{200}  particles per milliliter.

<h3>What is the result of the experiment in mixed fraction form?</h3>

To convert decimal to fraction, we the decimal number over 1 and multiply both the numerator and denominator by power of 10.

Given the data in the question;

  • Result of experiment in decimal form = 117.755
  • Result of experiment in mixed fraction form = ?

In 117.755, we have 3 numbers to the right of the decimal point.

We have 10³ which is the same as 1000.

\frac{117.755}{1} * \frac{1000}{1000}\\\\\frac{117755}{1000}

Next, we divide both the numerator and the denominator with their Greatest Common Factor.

Greatest Common Factor of 117755 and 1000 is 5

\frac{\frac{117755}{5} }{\frac{1000}{5} } = \frac{23551}{200}

Now, we can get 200 out of 23551 exactly 117 times, since what remained is not divisible by 200, we leave it as a remainder [151].

We can now write this in a mixed fraction form as;

117\frac{151}{200}

Therefore, the result of experiment in mixed fraction form is 117\frac{151}{200}  particles per milliliter.
