ABCD is a rectangle. If AC = 2x + 10 and BD = 56, find the value of x.

TEA [102]

9514 1404 393

Answer:

(b) 23

Step-by-step explanation:

The diagonals of a rectangle are the same length, so ...

AC = BD

2x +10 = 56

x +5 = 28 . . . . . divide by 2

x = 23 . . . . . . . . subtract 5

There are three different cubes such that the first cube is 64 times the volume of the second, and the volume of the second cube

tankabanditka [31]

Answer:

4/3

Step-by-step explanation:

If the ratio between the volumes of the first and the second cube is 64, the ratio between the sides is the cubic root of the ratio between the volumes, so:

$V1 / V2 = 64$

$s1 / s2 = \sqrt[3]{64} = 4$

Doing the same for the second and third cubes, we have:

$V2 / V3 = 1/27$

$s2/ s3 = \sqrt[3]{1/27} = 1/3$

So the ratio of the first cube side and the third cube side is:

$s1 / s3 = (s1/s2) * (s2/s3) = 4 * (1/3) = 4/3$

you have a bag full of 17 marbles. Of those marbles, 3 are black. What is the probability that a marble chosen is not black

sdas [7]

Total number of marbles = 17

3 are black.

Not black = 17 - 3 = 14.

Probability of not black = Number not black / Total

= 14 / 17
