You might have to ask your teacher or who ever is in charge of the class because you need to have the number of black markers because in this question it could be 5 sets of 10 markers or 5 sets of 13 markers. so you should ask your teacher.

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

1) Use the Euclidean Algorithm to nd the greatest common divisor of 71407 and 2020. (Write down all of the steps, so that you ar

Olenka [21]

Answer:

Step-by-step explanation:

We have

$71407 = 2000(35)+1407\\2000 = 1407+1(593)\\1407= 2(593) + 221\\593 = 2(221) = 151\\221=151+70\\151=2(70)+11\\70 = 6(11)+4\\11=2(4)+3\\4 = 3+1\\3 = 3(1)+0\\$

So we find GCD = 1

2) By back substitution we get

71407 (543) - 19387(2000) =1

So x = 543 and y = -19387

Because we got 71407 (543) - 19387(2000) =1

y cannot be positive

y can only be negative
