R u on this question still
Step-by-step explanation:
Plz dont take this down
- It's very long so I'm not giving answers but here's how i would do it:
- use Pythagoras
where c is the longest side - use sine rule
where lower cases are the sides, and capitals are their opposite angles.
e.g for 15:
a = 3, b is missing, c = 10
A is missing, B is ?, C is 90
The time to fill the sink if Blake forgets to put in the stopper would be 15 mins.
Step-by-step explanation:
Given that,
The kitchen sink can fill in: 6 mins
The sink can drain in: 10 mins
We have to find the time to fill the sink if Blake forgets to put in the stopper. For that,
Lets say, the full tank = 1
Filling rate = 
Drainage rate = 
Hence, the time to fill the tank would be:

(Multiply by LCM)


x = 15
Hence, the time to fill the sink if Blake forgets to put in the stopper would be 15 mins.
Answer:
c. The interquartile range offers a measure of income inequality among California residents.
Step-by-step explanation:

Answer:
2t-7
Step-by-step explanation:
distribute the 2, to the t and the -4
you should have 2t-8+1
then you add the 1 to the -8 and you get -7
resulting in 2t-7 being the answer
