The sqaure root of 130 falls between which consecutive numbers

You can use the following online calculator to answer your question. http://www.arachnoid.com/lutusp/finance.html you would make the folowing entries: Present Value = 738.14 Future Value = 0 Number of Payments is left blank because you want to solve for that. Payment Amount = -265.00 Interest Rate per period = 17.9% per year divided by 12 = 1.491666667% per month. Payment At is at End. click on the NP button and it will tell you the number of months required for the loan to be fully paid off. the calculator will show you that it will take 2.87 months for you to fully pay off the loan of $738.14 when you are paying it off at $265.00 at the end of each momth and the interest rate if 1.491666667% per month. now that you know how long it takes for you to pay it off, you can determine what the interest amount is that you paid. multiply your payment of 265 per month by 2.87 months to get a total payment of $ 760.55 your loan was for $738.14. the difference is the amount of interest you paid. that will be $760.55 - $738.14 = 22.41$\ you paid $22.41 in interest.

Find the area of the triangle 14cm 25cm

Anna71 [15]

Answer:

175 cm

Step-by-step explanation:

assuming it's a right triangle, the formula used is A= (1/2)(base)(height)

so (1/2)(14)(25)

which equals 175

The ratio of length and breadth of a rectangular playground is 3:2. There

Misha Larkins [42]

Answer:

We know that the ratio of length and breadth of a rectangular playground is 3:2

Then if the length is L, and the breadth is B, we have the relationship:

L = (3/2)*B

Outside this playground, we have a jogging track of 2m, then if we also consider the jogging track the length and breadth are:

L' = L + 2m

B' = B + 2m

The area is the product between the area and the breadth, then the area is:

A = B'*L'

A = (L + 2m)*(B + 2m)

And remember that L = (3/2)*B

Then we get:

A = ((3/2)*B + 2m)*(B + 2m)

And the area is 2816 m^2

Then we have:

A = ((3/2)*B + 2m)*(B + 2m) = 2816 m^2

Now we can solve the equation:

((3/2)*B + 2m)*(B + 2m) = 2816 m^2

(3/2)*B^2 + 3m*B + 2m*B + 4m^2 = 2816 m^2

(3/2)*B^2 + 5m*B = 2816 m^2 - 4m^2 = 2812m^2

Then we can write:

(3/2)*B^2 + 5m*B - 2812m^2 = 0

We can solve this if we use Bhaskara's formula:

$B = \frac{-(5m) +- \sqrt{(5m)^2 - 4*(3/2)*(-2812m^2)} }{2*(3/2)} = \frac{-5m +-130m}{3}$

One solution is negative, so we can discard that one, then we only take the positive:

B = (-5m + 130m)/3 = 41.67m

And L = (3/2)*B

L = (3/2)*40.7m = 62.5m

The breadth is 41.67 meters and the length is 62.5 meters.
