Answer:

Step-by-step explanation:

a) The interest generated over the 9 months is how much the woman paid for use of the money, then:

$I=C.t.i\\C=3000\\t=9\\i=3.5%=0.035\\I=3000.9.0.035=945\\I=945$

Therefore , the woman paid $945 for the use of the money.

b) The total amount that she repaid the bank is:

$C_{t} =C+I=3000+945=3945\\C_{t} =3945$

Finally we have that the woman paid $3945 to the bank

Simplify the expression: 7 + 24 / 6 * 10 *

Fittoniya [83]

Hi the answer is 47

Here is the step by step process

7+24/6*10

PEMDAS states that you do multiplication first but it matters if division or multiplication is first in the equation.

So based on the equation you would do division first.

You will have

7+4*10

Next you do multiplication

7+40

Your final answer is 47

Hope this helps! Have a great day!! :)

Answer:

$Solution,\\Area~of~triangle=\frac{1}{2} (base)(height) = \frac{1}{2}(2x+\frac{1}{4}) (x-8)\\~~~~~~~~~~~~~~~~~~~~~~~~ =\frac{1}{2}[2x^2-16x+\frac{1}{4}x-\frac{1}{4}(8)]\\ ~~~~~~~~~~~~~~~~~~~~~~~~ =\frac{1}{2}[2x^2-\frac{63}{4}x - 2]\\~~~~~~~~~~~~~~~~~~~~~~~~=x^2-\frac{63}{8}x-1$
