One way in which to approach this problem would be to treat it as an equation of ratios and to cross multiply:

<span>[(4x + 15) / 5x)] = 1/2  could be written as:

4x + 15        1
----------- =  ---
     5x           2

Then 8x + 30 = 5x

3x = -30,  and so     x = -10 (answer).  Be certain to check this answer through substitution!

Compound Interest: Hannah is putting 10,000 dollars in the bank for 5 years at 6% p.a every 6 months what is her Final Balance?
8090 [49]
I think you can solve it by doing this: 

10(10,000+0.06)= Final Balance 

6 months + 6 months = 1 year

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    She has to pay twice a year 


Now that we know that just multiply 2 by 5 and you get 10. 10(10,000+0.06)= Final Balance 

So it should be 100000.6

Not sure if that's right so ask someone to check

The circumference of a circle is 19 pi meters. What is the radius in meters?
Sliva [168]

Answer:

<h3>Area of a circle in terms of radius:</h3>

Area = π·r^2 = 3.14·9.5^2 = 283.5 square meters(*)

Area of a circle in terms of diameter:

Area = π·(d/2)^2 = 3.14·(19/2)^2 = 3.14·(9.5)^2 = 283.5 square meters(*)

Area of a circle in terms of circumference:

Area = C^2/4π = 59.69^2/4π = 3562.9/(4·3.14) = 3562.9/12.56 = 283.5 square meters(*)

(*) 283.52873698648 meters, exactly or limited to the precision of this calculator (13 decimal places).

Note: for simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.

Step-by-step explanation:

Hope it is helpful....
