Answer:

Step-by-step explanation:

Write 34 in tens and units.

34 = 30 + 4

9(30 + 4)

9 * 30 = 270

9* 4 = 36

270 + 36 = 306

After awhile if your practice enough, you can do them in your head.

Find the interest on naira 40000.00 for 2 years at 20% per annum compound interest. Please I need the answer ASAP

andrey2020 [161]

Given:

Principal value = 40000

Rate of compounded interest = 20%

Time = 2 years

To find:

The interest.

Solution:

Formula for amount is

$A=P\left(1+\dfrac{r}{100}\right)^t$

Where, P is principal, r is rate of interest and t is time in years.

Putting the given values, we get

$A=40000\left(1+\dfrac{20}{100}\right)^2$

$A=40000\left(1+\dfrac{1}{5}\right)^2$

$A=40000\left(\dfrac{6}{5}\right)^2$

$A=40000\left(\dfrac{36}{25}\right)$

$A=57600$

Now, the formula for interest is

$I=A-P$

$I=57600-40000$

$I=17600$

Therefore, the amount of compound interest is 17,600.

How would the fraction <img src="https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B1-%5Csqrt%7B5%7D%20%7D" id="TexFormula1" title="\frac{

allsm [11]

Answer:

$\frac{7 + 7 \sqrt{5} }{ - 4}$

Step-by-step explanation:

We would multiply the fraction by its conjugate

( A conjugate is a expression that has the same integer or number values but have different signs) for example

$5x + 2$

and

$5x - 2$

ARE Conjugates.

The conjugate of

$1 - \sqrt{5}$

$1 + \sqrt{5}$

So this means we will multiply the expression by 1 plus sqr root of 5 on the numerator and denominator.

Our new numerator will be

$7 \times (1 + \sqrt{5} ) = 7 + 7 \sqrt{5}$

We can apply the difference of squares for the denominator.

$(x + y)(x - y) = x {}^{2} - {y}^{2}$

So our denominator will be

$1 - 5 = - 4$

So our rationalized fraction will be

$\frac{7 + 7 \sqrt{5} }{ - 4}$
