9514 1404 393

Answer:

  1. 70°
  2. 55°
  3. 35°
  4. 35°

Step-by-step explanation:

An inscribed angle is half the measure of the central angle that intercepts the same arc.

__

(i) 35° = x/2   ⇒   x = 70°

(ii) x = 110°/2 = 55°

(iii) x = 70°/2 = 35°

(iv) x = 90° -55° = 35° . . . . a triangle inscribed in a semicircle is a right triangle

Step-by-step explanation:

#1

Centre = O

x = 35 × 2

x = 70⁰

#2

Centre = O

x = 110/2

x = 55⁰

#3

Centre = O

x = 70/2

x = 35⁰

#4

Centre = O

A right angle triangle has a side of 90⁰

x = 90 - 55

x = 35

A bag has 30 tiles, numbered 1-30. Write the ratio even tiles to odd tiles in simplest form.
guapka [62]

Answer:

r=1

Step-by-step explanation:

<u>Ratio of Values </u>

A ratio compares two values by diving them. If the ratio is greater than one, then the value in the numerator is greater than the value in the denominator. The opposite relation gives ratios lower than 1. A ratio of 1 means both values are the same

We have a set of tiles numbered 1 to 30:

1,2,3,4,5,6...,29,30

Note that each odd-numbered tile is followed by an even-numbered tile. It means we have 15 odd tiles and 15 even tiles. The ratio is

\displaystyle r=\frac{even}{odd}

\displaystyle r=\frac{15}{15}

r=1

nalin [4]

Answer:

12870ways

Step-by-step explanation:

Combination has to do with selection

Total members in a tennis club = 15

number of men = 8

number of women = 7

Number of team consisting of women will be expressed as 15C7

15C7 = 15!/(15-7)!7!

15C7 = 15!/8!7!

15C7 = 15*14*13*12*11*10*9*8!/8!7!

15C7 = 15*14*13*12*11*10*9/7 * 6 * 5 * 4 * 3 * 2

15C7  = 15*14*13*12*11/56

15C7 = 6,435 ways

Number of team consisting of men will be expressed as 15C8

15C8 = 15!/8!7!

15C8 = 15*14*13*12*11*10*9*8!/8!7!

15C8 = 15*14*13*12*11*10*9/7 * 6 * 5 * 4 * 3 * 2

15C8 = 6,435 ways

Adding both

Total ways = 6,435 ways + 6,435 ways

Total ways = 12870ways

Hence the required number of ways is 12870ways
