Answer:
8000
Step-by-step explanation:
Basically you want a number to multiply the number of kids by to get adults. So what number can you multiply 3 by to get 5? 5/3. So now any number of kids, if you multiply it by 5/3 you wll get the number of adults. This is how proportions work.
so 4800 kids means there are 5/3 * 4800 adults or 8000 adults.
Another way to look at it is how much do you multiply 3 by to get 4800. Whatever that number is you also multiply 5 by to find the corresponding number of adults. 4800/3 = 1600, 5*1600 = 8000
Answer: 1/cos θ
Step-by-step explanation:
From basic trigonometry, csc θ is the short form of cosec θ which is further expressed as
csc θ = 1/sin θ
Also,
tan θ = sin θ/cos θ
Knowing this basis of trigonometry makes the simplification easy for us.
Firstly, expressing the equation in terms of sin θ and cos θ,
The equation becomes csc θ * tan θ = [1/sin θ] * [sin θ/ cos θ]
Further simplifying by multiplication, our answer becomes
1/cos θ
It could be C Let me know if I am right or not!
