In trapezoid ABCD with bases AB and DC , diagonals intersect at point O. Find the length of diagonal BD , if BO=6 cm and: AO/OC
aalyn [17]

Answer:

8 cm

Step-by-step explanation:

... BO/OD = AO/OC = 3/1

Written another way, this is ...

... OD : BO = 1 : 3

Now, BD = OD + BO, so we have

... BD : BO = (OD +BO) : BO = (1 +3) : 3 = 4 : 3

That is, BD = 4/3 × BO

... BD = 4/3 × 6 cm = 8 cm

-BARSIC- [3]

Answer:

12/(7-4) + 5 * 3 = 19

Step-by-step explanation:

Given

Untrue Expression: 12 ( 7 − 4 ) + 5 3 = 19

Signs: +−×÷

Required

Use the given signs to make the equation true.

To solve this, the trial and error method will be adopted.

The trial and error method involves trying series of sign combinations in the given expression; whichever works is the right answer.

So, after few attempts the following makes the equation true

12/(7-4) + 5 * 3 = 19

To check if it's true or not; we simply expand the expression on the left hand side. This gives

12/3 + 5 * 3 = 19

4 + 5 * 3 = 19

4 + 15 = 19

19 = 19.

Hence, the sign combinations used in 12/(7-4) + 5 * 3 = 19 is correct.

AlladinOne [14]
Formula is

d = d(10^k+p - 10^k) / 10^k+p - 10^k

where d = the decimal;
k = number of the non repeating decimal digits; which in this case is one
p = repeating decimal digits which in this case is one
