Answer:
If you are looking for x it equals 80 degrees
Step-by-step explanation:
vertical angles are congruent
Answer:
Step-by-step explanation:
The given triangle is isosceles. Therefore the base angles are equal.
This implies that,
.
To find 
we add the interior add angles and equate to 
.
This implies,
We substitute to obtain,
We evaluate to obtain,
We divide through by 3 to get.
Answer:
There is no clear relationship between the number of times students arrive late and the distances they live from school.
Step-by-step explanation:
By looking at the graph, there is no clear direction or association that the graph has. Therefore, there is no clear relationship between the variables being compared.
Answer:
19,600.
Step-by-step explanation:
Combination as the order of applicants des not matter.
Number of ways = 50C3
= (50*49*48)/ (3*2*1)
= 50*49*8
= 19,600.
Define
v = value after t years.
Therefore the linear model is
v = mt + c
where
m = depreciation rate
t = years since purchase
c = constant
When t=0, v = 20,000, therefore
20000 = m(0) + c
c = 20000
When t=10, v = 2000, therefore
2000 = 10m + 20000
-18000 = 10m
m = -1800
Answer:
The linear model is
v = -1800t + 20000
