Answer:
7/6π, 1/6π
Step-by-step explanation:
We know that tan is sine/cosine, so cot is cosine/sine.
In this case, we know cotθ = √3
As the number is positive, using the unit circle, we now can say that the two solutions are in quadrants I and III.
Taking a look at the unit circle, we can finalize our answer.
The actual answer is 154 but the closest estimate would be 150.
Just multiply the number of gallons filled her gas tank (14) and how many time she filled it (11).
A) x * y = 12
B) x + y = -7
A) x = 12 / y
Substitute this into B
B) 12/y + y = -7
multiplying both sides by "y"
12 + y^2 = -7y
y^2 + 7y + 12 = 0
y = -4
and from equation B we calculate x as -3
Answer:
20 homes
Step-by-step explanation:
Given that :
Total number of homes = 800
Average years at which homes are listed = 8 years
To obtain the annual home listing = total number of Homes / average years
Annual home listing = 800 / 8
Annual home listing = 100 homes
If 20% of the homes are listed on the year in question :
20% of 100 homes
0.2 * 100
= 20 homes
20 homes can be listed that year
