Answer:
1/5
Step-by-step explanation:
4/5 - 3/5 equals 1/5
Answer:
cot(θ)=5/12
Step-by-step explanation:
(I'm going to replace theta with x to save time.)
Recall that sine is equal to opposite over hypotenuse. Thus:
sin(x)=12/13, this means that the opposite side is 12 while the hypotenuse is 13 (well, it doesn't have to be, but their ratios are).
Find the adjacent side using the Pythagorean Theorem.
13^2 = 12^2 + adj^2
adj^2 = 25
adj = 5.
Recall that tan(x) is opposite over adjacent. This means that cot(x) is adjacent is opposite.
Therefore: cot(x) = 5/12.
Answer:
$10
Step-by-step explanation:
We presume the car wash pay was in addition to his allowance, so without it he would have ended with $5.
If that $5 is the half of his allowance he did not spend going to the movies, then his weekly allowance is $10.
Answer:
Current impact in pollution units per day=21.6 billion pollution units per day
Step-by-step explanation:
1 person consumes 3000 kilo-calories per person
Current population=7.2 billion people
Total calories the entire population produces=(7.2 billion×3000)
1000 kilo-calories causes= 1 pollution unit
To get the impact of the entire population=(7.2 billion×3000)/1000=21.6 billion pollution units per day
