defon

Answer:

$BD = 12\ cm$

Step-by-step explanation:

Given

Shape: Rectangle

Diagonals: AC and BD

$AC = 12\ cm$

Required

Determine BD

From the question, we understand that the shape is a rectangle and its diagonals are AC and BD

Every rectangle has 2 diagonals, both of which are equal.

This implies that:

$BD = AC$

Recall that:

$AC = 12\ cm$

Hence,

$BD = 12\ cm$

If A and B are two points having coordinates (- 2, 2) and (2,-4) respectively, find the coordinates of P such that AP= AB.

Karo-lina-s [1.5K]

Answer:

(0,1)

Step-by-step explanation:

The mid point of A(-2,2) and B(2,-4) is the coordinates of point P, which is (x,y)

Hence, the line AB = AP + PB.

At point AP: x = (-2+2)/2 = 0

also, point PB: y = (2 - 4)/2 = -1

Therefore, coordinates of point P = (0,-1)

Mr. Ahmed has 31 students in his class. There are 14 boys and 17 girls.

densk [106]

Since there are 14 boys and the whole class has 31 students
We get, the ratio of the part-to-whole relationship for boys is 14/31.

And since there are 17 girls
We get, the ratio of the part-to-whole relationship for girls is 17/31.
