The local shelter decided to build an addition for cats hey borrowed $6300 from a local bank at a rate of 8% the high school hel

Zepler [3.9K]

Answer:

$378

Step-by-step explanation:

To find the interest that the shelter payed on this loan, we use the formula: $I=Prt$ .

P = $6,300

r = 8% or 0.08

t = 9/12

Now we substitute the values into our formula.

$I=Prt$ .

$I=6,300(0.08*\dfrac{9}{12})$

$I=6,300(0.08*0.75)$

$I=6,300(0.06)$

$I=$378$

So the shelter payed a total of $378 in interest to the bank.

What is 7.69/43.685=?<br> including long division <br> I'll give brainliest.

Minchanka [31]

$Question$

what is 7.69/43.685=?

Answer:

The Correct Answer is 5.6 :)

Step-by-step explanation:

Change the divisor 7.69 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.

We then have the equations:

4368.5 ÷ 769 = 5.6

and therefore:

43.685 ÷ 7.69 = 5.6

Both calculated to 1 decimal places.
