You have a map where indy and fort wayne are 13 centimeter apart. kokomo and indy are 6.5 cm apart on the map. if you know that

Bond [772]

Since 6.5 is half of 13,you just need to find out what is half of 120,and that would be 60 miles apart,if all three are in a straight line and indy is in the middle,is there a map to go along with this question?

At least how many grams of copper must be alloyed with 387 g of pure silver to produce an alloy that is no more than 90% pure si

cricket20 [7]

Let c = grams of copper to be added

(grams of silver) / (grams of copper and silver) < = .90

387+%2F+%28c+%2B+387%29+%3C=+.9

387+%3C=+.9%28c+%2B+387%29

387+%3C=+.9c+%2B+348.3

.9c+%3E=+387+-+348.3

.9c+%3E=+38.7

c+%3E=+43g

At least 43 grams of copper must be added

check:

387+%2F+%28c+%2B+387%29+%3C=+.9

387+%2F+%2843+%2B+387%29+%3C=+.9

387+%2F+430+%3C=+.9

.9+%3C=+.9

Anna’s bank gives her a loan with a stated interest rate of 10.22%. How much greater will Anna’s effective interest rate be if t

Mumz [18]

Answer:

d. 0.0463% points.

Step-by-step explanation:

We have been given that Anna's bank gives her a loan with a stated interest rate of 10.22%.

To find the how mush the interest rate is effective, while compounded daily than compounded monthly, we will find the difference between interest compounded daily from interest compounded monthly.

$\text{The effectiveness of interest rate compounded daily}=(1+\frac{r}{365})^{365}-(1+\frac{r}{12})^{12}$

Let us convert our given rate in decimal form.

$10.22\%=\frac{10.22}{100}=0.1022$

Upon substituting our given interest rate in above equation we will get,

$\text{The effectiveness of interest rate compounded daily}=(1+\frac{0.1022}{365})^{365}-(1+\frac{0.1022}{12})^{12}$

$\text{The effectiveness of interest rate compounded daily}=(1+0.00028)^{365}-(1+0.008516666)^{12}$

$\text{The effectiveness of interest rate compounded daily}=(1.00028)^{365}-(1.008516666)^{12}$

$\text{The effectiveness of interest rate compounded daily}=1.1075891260304368-1.1071257622419648$

$\text{The effectiveness of interest rate compounded daily}=0.000463363788$

Let us convert our rate in percentage by multiplying our answer by 100.

$\text{The effectiveness of interest rate compounded daily}=0.000463363788*100$

$\text{The effectiveness of interest rate compounded daily}=0.0463363788\%$

Therefore, the Anna's effective interest rate will be 0.04633% points and option d is the correct choice.
