Figure ABCD is a kite. The area of ABCD is 48 square units. The length of line segment BD is 8 units. What is the length of AC?

Fed [463]

A = d1 x d2 / 2

d1 = BD = 8 units

48 = 8 x AC / 2

48 x 2 = 8 AC

96 = 8 AC

AC = 96 : 8 = 12

Answer: D ) 12 units

Jim was thinking of a number. Jim adds 20 to it, then doubles it and gets an answer of 99.2. What was the original number?

azamat

Alright, lets get started.

Jim was thinking of a number.

Suppose the number Jim was thinking, is x.

Jim adds 20 to it means number will be = $x+20$

And Jim doubles it, means $2*(x+20)$

Jim gets 99.2 and as per us, he gets $2*(x+20)$

So, making them equal

$2(x+20)=99.2$

$2x+40=99.2$

Subtracting 40 in both sides

$2x+40-40=99.2-40$

$2x=59.2$

$x=29.6$

It means the original number is 29.6. : Answer

Hope it will help :)

What is the circumference of a circle whose radius is 13?

Inessa05 [86]

Answer:

Circumference, C = 81.68 units

Step-by-step explanation:

Given that,

The radius of the circle, r = 13 units

We need to find the circumference of the circle. The circumference of a circle is the sum of the outer boundary. For a circle, it is given by :

$C=2\ \pi r$

$C=2\ \pi \times 13$

C = 81.68 units

So, the circumference of the circle is 81.68 units. Hence, this is the required solution.
