The answer is 8 3/4 is the answer
Answer:
C Because divide 56/7 =8.
Answer:
a) 66
b) 45
Step-by-step explanation:
We have 12 horses and after the first race 2 of them have to be eliminated
that condition is equal to consider that 10 horses will be available for the second race.
The number of possiblities we have for the first race is the combination of 12 horses in group of 10
C¹²₁₀ = 12!/ (2!)* (12-2)! = 12*11/2 = 66
For the second race
C¹⁰₈ = 10! / 8! * (10-8)! = 10*9/ 2 = 45
You need to draw the triangle DEF with a right angle at E. Angle D = 40 and DE = 100 m. Once you have marked up your triangle, you can use cosine to find DF.
Volume of cylinders = pi x r^2 x height
Simplifying the ratio:
1.6/3 = 16 / 30 (multiply and divide by 10 to remove the decimal)

Volume Ratio = 512:27</span>
