In order to find the surface area of a rectangle:

-- Find or measure the length of the rectangle.

-- Find or measure the width of the rectangle.

-- Make sure both quantities are in the same units.
If they're not, then convert one or the other so that they are.

-- Multiply the two numbers.

The product is the area of the rectangle, in units of
square-(the unit in which the dimensions are measured).

Hi there! I can help you! 8 + (-9) + (-2). When adding negative integers, you have to subtract. 8 - 9 is -1 and -1 - 2 is -3. You would have to start at 8 and go to the left 11 times to land on -3. The sum to the problem is -3.

Find the savings plan balance after 2 years with an APR of 4% and monthly payments of $250. The balance is $ (Do not round until

alexdok [17]

Answer:

$6,506.51

Step-by-step explanation:

Recall that increasing an amount C in x% is equivalent to multiply it by (1+x/100)

As we have 4% APR, the monthly interest would be (4/12)% = 0.04/12

<u>Month 0</u> (first payment)

$250

Month 1

$250 + 250 \frac{0.04}{12}= 250(\frac{12.04}{12})$

<u>Month 2</u>

$250(1+\frac{12.04}{12}+(\frac{12.04}{12})^2)$

<u>Month 3</u>

$250(1+\frac{12.04}{12}+(\frac{12.04}{12})^2+(\frac{12.04}{12})^3)$

<u>Month 24 (2 years)</u>

$250(1+\frac{12.04}{12}+(\frac{12.04}{12})^2+(\frac{12.04}{12})^3+...+(\frac{12.04}{12})^{24})$

The sum

$1+\frac{12.04}{12}+(\frac{12.04}{12})^2+(\frac{12.04}{12})^3+...+(\frac{12.04}{12})^{24}$

is the sum of the first 24 terms of a geometric sequence with common ratio $\frac{12.04}{12}$ which is

$\frac{1-(12.04/12)^{25}}{1-(12.04/12)}=26.02603071$

so, after 2 years the saving balance is

250*26.02603071 = 6,506.50767= $6,506.51 rounded to the nearest cent.

Answer:

0.67

Step-by-step explanation:

To solve this we are going to use this lovely equation

P%•X=Y

Y is our end product

X in this case is 45

and P% is our percent

Now let's multiply 4% which becomes .004 by 45 and we get 1.8 which since there isn't 1.8 in American currency that becomes $1.80

We do the same process with the 2.5

0.025•45=1.125

Again not in the American currency so we will round 5 up and now we have $1.13

Now we subtract 1.80-1.13 which gets us 0.67 cents.

Hope I was helpful,
