Answer:

  a)  1120

Step-by-step explanation:

If 28 and 40 are denominators of fractions, one way to find a common denominator is to simply multiply these values:

  28×40 = 1120 . . . . a possible common denominator

__

The Least Common Denominator is the least common multiple (LCM) of these denominator numbers. The LCM is their product, divided by their greatest common factor. Here, that factor is 4, so the<em> least</em> common denominator is 1120/4 = 280.

Speed = Distance/Time 

Runner Speed = 200/21.3 = 9.4 m/s 

Swimmer Speed = 1.8 m/s 

9.4 - 1.8 = 7.6 m/s

In trapiziod ABCD with bases AB and DC , diagonals intersect at point O. Find the length of diagonal BD, if BO=6 cm and A/O=3/1
ElenaW [278]

Answer:

the length of the diagonal BD is 8 cm

Step-by-step explanation:

The computation of the length of diagonal BD is as follows

Here the trapezoid diagonals divides each other in an equivalent ratio

So, equation would be

AO ÷ OC = OB ÷ OD

Now put there values to the above equation

3 ÷ 1 = 6 ÷ OD

3OD = 6

Now divided it by 3 in both the sides

OD = 2

Now the BD would be

= BO + OD

= 6 +  2

= 8 cm

hence, the length of the diagonal BD is 8 cm
