AB:BD = 3:4 <br><br> AC:CD = 3:2 <br><br> Work out AB:BC:CD
Papessa [141]

Answer:

15:6:14

Step-by-step explanation:

AB:BD is split into a total of 3+4=7 parts.

AC:CD is split into a total of 3+2=5 parts.

So, if the two ratios are put on a number line together with the points A, B, C, and D, the number line would be split into a total of 35 parts (the LCM of 7 and 5).

AB would be (3/7)*35=15.

CD would be (2/5)*35=14

BC would be 35-(15+14)=6

So, the ratio is 15:6:14.

Determine and state the coordinates of the center and the length of the radius of a circle whose equation is x² + y² - 6x = 56 -
natali 33 [55]

Answer:

The center is at (3, -4), and the radius is 9.

Step-by-step explanation:

x² + y² − 6x = 56 − 8y

Move x and y terms to one side.

x² − 6x + y² + 8y = 56

Complete the squares.

x² − 6x + 9 + y² + 8y + 16 = 56 + 9 + 16

(x − 3)² + (y + 4)² = 81

The center is at (3, -4), and the radius is 9.

rusak2 [61]
You can make a 6 x 6 square to illustrate  the probabilities 

   1 2 3 4 5 6
1 2 3 4 5 6 7
2 3 4 5 6 7 8
3 4 5 6 7 8 9
4 5 6 7 8 9 *
5 6 7 8 9  * &
6 7 8 9  * & $

* =10, & =11, $ = 12, I wanted maintain spacing

There are 3 4's. So it is 3/36 chance, which is 1/12 chance.

The lengths of two sides of a triangle are 12 ft and 13 ft. find the range of possible lengths for the third side
mihalych1998 [28]
Let x be the length of third side.
12 + x > 13
x > 1-------------(1)
13 + x > 12
x > -1 ------------(2)
by combining (1) and (2)
we have x > -1
