Answer:

5 cm

Step-by-step explanation:

Let the length of pencil B be 2x cm. Then, A/Q

the length of pencil A is (2x-11)cm and the length of pencil C is x cm.

So,

(2x-11)+2x+x = 29, or

5x = 40, or

x = 8 cm.

Now, the length of pencil A is given by (2x-11)cm and we know the value of x as 8 cm. Therefore, putting the value of x in Eq. (2x-11)cm , we get the length of pencil A as 5 cm.

Find the circumference of a circle that has an area of 452.16 square meters. (Use 3.1416 as the value of π.)
boyakko [2]
452.16 = 3.1416 r^2
r^2 = 452.16  /  3.1416
r^2 = 143.93
r = 11.997

C = 2 (3.1416) (12) =75.38 m

On a single roll of a pair of dice, what are the odds against rolling a sum of 12?
o-na [289]

Answer:

\frac{1}{35}

Step-by-step explanation:

On a single roll of a pair of dice. When a pair of dice are rolled the possible outcomes are as follows:

(1,1)         (1,2)          (1,3)  (1,4)  (1,5)  (1,6)

(2,1)  (2,2)  (2,3)  (2,4)  (2,5)  (2,6)

(3,1)  (3,2)  (3,3)  (3,4)  (3,5)  (3,6)

(4,1)  (4,2)  (4,3)  (4,4)  (4,5)  (4,6)

(5,1)  (5,2)  (5,3)  (5,4)  (5,5)  (5,6)

(6,1)  (6,2)  (6,3)  (6,4)  (6,5)  (6,6)

The number of outcomes that gives us 12 are (6,6). There is only one outcome that gives us sum 12.

Total outcomes = 36

Odd against favor = \frac{non \ favorable\ outcomes}{favorable \ outcomes}

Number of outcomes of getting sum 12 is 1

Number of outcomes of not getting sum 12 is 36-1= 35

odds against rolling a sum of 12= \frac{1}{35}
