Answer:
31 animals
Step-by-step explanation:
1 rabbit + 6 elephants + 6*2=12monkeys + 12 parrots = 31 animals
Answer:
sin(x) and cos(y) are equal and have ratio of 1 : 1
First find the missing hypotenuse using Pythagoras theorem:
a² + b² = c²
12² + 5² = c²
c = √144+25
c = 13
using sine rule:


using cosine rule:


The answer is B. 10 vertices because it all depends on the edges. You have to subtract the edges by faces/vertices to get your faces/vertices so 20-12 is 10 so you are correct
0.7 can also be written as 7/10. All you need to do is multiply 7/10 by 1/10. You will get 7/100 which is 0.07
