Find the distance between the points (2,0) and (-4,6)
N76 [4]

Answer:

You have to move 6 times to the left and 6 times down.

Step-by-step explanation:

If you're at (2,0), you move 2 times to the left, and then you're at (0,0).

Next move 4 times to the left. Now you're at (-4,0).

Now, move 6 times down, and now, you're at (-4,-6).

Suppose you loan $320 to a friend and charge them 11% annual interest. If they don't pay you back, how much will they owe you af
RSB [31]

Answer:

Step-by-step explanation:

You want to calculate the interest on $320 at 11% interest per year after 5 year(s).

The formula we'll use for this is the simple interest formula, or:

Where:

   P is the principal amount, $320.00.

   r is the interest rate, 11% per year, or in decimal form, 11/100=0.11.

   t is the time involved, 5....year(s) time periods.

   So, t is 5....year time periods.

To find the simple interest, we multiply 320 × 0.11 × 5 to get that:

The interest is: $176.00

Usually now, the interest is added onto the principal to figure some new amount after 5 year(s),

or 320.00 + 176.00 = 496.00. For example:

   If you borrowed the $320.00, you would now owe $496.00

   If you loaned someone $320.00, you would now be due $496.00

Mr Oneill bought cheese, turkey slices and wheat rolls for $55. The ratio of the amount of money spent on cheese to the amount o
astra-53 [7]

Answer:

Mr. O'neill buy 33 turkey slices.

Step-by-step explanation:

Firstly let us denote <em>amount of money spent on Cheese by the symbol C.</em>

<em>                                  amount of money spent on Turkey by the symbol T.</em>

<em>                                   amount of money spent on Wheat by the symbol W.</em>

Now we are the ratio of amount of money spent on cheese to the amount of money spent on turkey slices as 2:3 ;

       We can represent this as  \frac{C}{T} = \frac{2}{3}

The ratio of the amount of money spent on cheese to the amount of money spent on wheat rolls is 6:5 ;

        We can represent this as  \frac{C}{W} = \frac{6}{5}

Now we will make C also 6 in the first ratio to represent similarity in ratios i.e.     \frac{C}{T} = \frac{2 * 3}{3 * 3} = \frac{6}{9}

So, the ratio of amount of money spent on cheese to the amount of money spent on turkey slices to the amount of money spent on wheat rolls is represented by 6 : 9 : 5.

To find the amount of money spent on turkey slices = \frac{9}{6+9+5} * $55 = $24.75

Since cost of each turkey slice cost = $ 0.75

Therefore, Cost of each turkey slice * Number of turkey slices = Total amount of money spent on turkey slices

    $0.75 * Number of turkey slices = $24.75

Therefore, Number of turkey slices that Mr. O'neill buy = $24.75/$0.75

                                                                                            = 33 slices.
