Answer:
approximately 21, when rounded to nearest tenth.
Step-by-step explanation:
First, let's find the measure of angle BAD. Angles BAD and DAC add up to 180 degrees, so 180-57= 123 degrees. Now, let's find the circumference of the circle. The circumference is diameter * π, which is 19.6(π). Then, the ratio is 123/360, so multiply 19.6(π) by 123/360, and you get 21.0381988...... which simplifies to 21 (rounded to nearest tenth)
Answer:
b. 8.7
Step-by-step explanation:
Answer:
Total number of people = 13
A:
Number of ways to choose 10 players to take the field = 13C10
= 
= 286
B:
This is given as: 13P10
= 
= 
= 1037836800
C:
This is given as:
(3C1 x 10C9) + (3C2 x 10C8) + (3C3 x 10C7)
Solving this we get the answer as = 285
288 divided by 12 = 24
240 divided by 10 = 24
