Answer:

Step-by-step explanation:

OA ⊥ OC

Therefore, m∠AOC = 90°

m∠AOC = m∠AOB + m∠BOC

m∠AOB + m∠BOC = 90

5x+8 + 6x - 6 = 90

11x + 2 = 90

11x = 90-2

11x = 88

x = 88/11

x = 8

m∠BOC = 6x - 6 = 6*8 - 6 = 48 - 6 = 42°

What is the missing number in the series?<br><br> 1, 16, 81, __, 625, 1296
Alinara [238K]

Answer:

256

Step-by-step explanation:

We are given the series

1, 16, 81, __, 625, 1296

The missing number in the sequence is the fourth term

From the above sequence, we know that

1, 4², 9² , __, 25² , 36²

Difference between first term = 4 - 1 = 3

9 - 4 = 5

x - 9 = 7

x = 9 + 7 = 16

Hence, the fourth term = 16²

= 256

Answer:

V = 108,000,000pi or V = 339292007mm

Step-by-step explanation:

V = pi × r^2 × h

To find radius with circumference:

Radius = Circumference / 2pi

So, 1884/2pi = 299.847913 = 300

V = pi × 300^2 × 1200

V = pi × 90000 × 1200

V = pi × 108000000

V = 108,000,000pi or V = 339292007

so the number 2 is having negative sign, we make it positive. this rule is applied only when there is a negative sign and a bracket is there.

-3-(-2)

-3+2

=-1
