What is the area of this ^2

Ad libitum [116K]

<h2>Question:- Area of the given diagram</h2>

<h2>Answer :- </h2>

Divide the diagram as shown in attachment.

Now first calculate the area of the rectangle having side 1 and 12

So area = length ×breadth

Area = 1× 12 = 12 unit²

Now find the Area of the remaining triangle with sides 12,13,5 units

$Area = \frac{1}{2} \times base \times height \:$

Now put the value as -> base= 5 and height= 12

$Area = \frac{1}{2} \times base \times height \: \\ Area = \frac{1}{2} \times 5 \times 12 \\ Area = \frac{1}{ \cancel2} \times 5 \times \cancel{12}^{ \: \: 6} \\ Area = 5 \times 6 \\ Area = 30 \: units^{2}$

Now add both areas for your answer

$Area{ \tiny{1}} = 12 {units}^{2} \\ Area{ \tiny2} = 30 {units}^{2} \\ Area{ \tiny{total}} = Area{ \tiny{1}} + Area{ \tiny{2}} \\ Area{ \tiny{total}} = 12 + 30 = 42 {units}^{2}$

I have a goal of getting exactly $100. But I have to pay a tax of 10%. How much money do I need to get in order to have exactly

<h3>Answer: $111.11</h3>

=======================================================

Explanation:

Let's say you earn x dollars.

You pay 10% tax on that, which means you pay 0.10x dollars.

This would drop to x-0.10x = 0.90x which is the amount earned after tax.

So you pay 10% of what you earn, and keep 90% of the rest.

Set this equal to the target $100 you want and solve for x.

0.90x = 100

x = 100/0.90

x = 111.11

Notice that 10% of this is 0.10*x = 0.10*111.11 = 1.11 when rounding to the nearest penny. So you'll pay $1.11 in tax. Therefore, you'd have x-0.10x = 111.11 - 1.11 = 100 left over. So the answer checks out.

PLEASE HELP ME! WILL GIVE **BRAINLIEST**

Answer:

See attached. (Note that b, d, f, h, j are cents amounts. All the other letters refer to the dollar amounts only (no cents).)

Step-by-step explanation:

The one deposit is marked with a (+) in the third column of Figure 4.16a. All the other transactions are Payment/Debit transactions. The balance on each line is the balance on the previous line less any payment and plus any deposit on that line. (It's not rocket science.)

If you actually do this in a spreadsheet, it is convenient to let the spreadsheet do the math. It is much easier to let the spreadsheet keep track of dollars and cents in the same column.

It is more difficult to break out cents to a separate column. So, your letter answers apparently need to be the dollar portion only (except as indicated above).
