One-half (80) because the answer to that would be 40 and the answer to the question would be 34.2
Answer:
B. 65°
Step-by-step explanation:
Angles on a straight line add up to 180 degrees.
180 - 130 = 50
Angles in a triangle add up to 180 degrees.
y + y + 50 = 180
2y + 50 = 180
2y = 180 -50
2y = 130
y = 130/2
y = 65

Answer:
$12.78.
Step-by-step explanation:
To determine the expected price of a good in 2000, knowing that in 2015 it cost $ 17.6 and that the consumer price indexes were worth 172.2 in 2000 and 237.017 in 2015, the following calculation must be performed:
237.037 = 17.6
172.2 = X
X = 172.2 x 17.6 / 237.037
X = 3,030.72 / 237.037
X = 12.78
Thus, the expected price of the good in the year 2000 is $ 12.78.
