The distance on a map between two cities is 6.5 cm if 1 cm = 8k on the map how many miles are the two cites apart from each othe

DedPeter [7]

So firstly, we have to convert 6.5 cm into km. Do this by multiplying 6.5 by 8:

$6.5\times 8=52\ \textsf{km}$

Next, we have to convert km to miles. Do this by multiplying 52 by 0.621:

$52\times 0.621=32.292\ \textsf{mi}\ \approx 32.3\ \textsf{mi}$

<u>The cities are (rounded to the tenths) 32.3 miles from each other.</u>

$17,818 is invested, part at 11% and the rest at 6%. If the interest earned from the amount invested at 11% exceeds the interest

erma4kov [3.2K]

Answer:We know the total amount of money invested. $17818

x+y=17818,

We know that the difference in interest earned by the two accounts is $490.33

0.11*x-0.06*y=490.33

x=17818-y

We substitute for x

0.11*(17818-y)-0.06*y=490.33

We multiply out

1959.98-0.11y-0.06*y=490.33

We combine like terms.

1469.65=0.17*y

Isolate y

y=1469.65/0.17

y=8645 at 6%

Calculate x

x=17818-8645

x=9173 at 11%

Check

0.11*9173-0.06*8645=490.33

interest earned at 11%=1009.03

interest earned at 6%=518.70

1009.03-518.7=490.33

490.33=490.33

Since this statement is TRUE and neither amount is negative then all is well.We know the total amount of money invested. $17818

x+y=17818,

We know that the difference in interest earned by the two accounts is $490.33

0.11*x-0.06*y=490.33

We substitute for x

interest earned at 6%=518.70

1009.03-518.7=490.33

490.33=490.33

Since this statement is TRUE and neither amount is negative then all is well.

marshall27 [118]

Answer:

$\frac{1cm}{125 meters}$

Step-by-step explanation:

To find the scale, we write a ratio of $\frac{map}{real world}$ and simplify.

We know $\frac{map}{real world}=\frac{8cm}{1000 meters}$ .

We simplify to $\frac{1cm}{125 meters}$
