Not how to show all work, as ive never worked with functions with absolute values.
The answer however should be -8.
Answer:
C) 155
Step-by-step explanation:
all these angles add up to 360, so --
25 + 34 + 146 + m<9 = 360
205 + m<9 = 360
m<9 = 155, C)
(1) 34.8 liters
(2) $63.55
Solution:
(1) There is a mistake in question. It is 42 liters.
Total gasoline a car can hold = 42 liters
Liters of gasoline filled in beginning of the week = 35.8
Liters of gasoline used during the week = 28.6
Remaining liters of gasoline in the tank = 35.8 – 28.6
= 7.2 liters
Quantity of gasoline need to buy to fill the tank completely
= Total capacity – Remaining gas in the tank
= 42 liters – 7.2 liters
= 34.8 liters
Hence Alberto need to buy 34.8 liters of gasoline to fill the tank.
Option B is the correct answer.
(2)
Shamika earns in first week = $25.75
Shamika earns in next week = $37.80
Total money Shamika have = First week earning + Second week earning
= $25.75 + $37.80
= $63.55
Don't add or subtract spending money, because the question is how much she have from these two weeks.
Hence Shamika have $63.55 from these two weeks.
Part a: hexagon is a six sided polygon.
Part b: dodecagon is a 12 sided polygon.
Part c: decagon is a 10 sided polygon.
Explanation:
Part a: The given polygon consists of 6 sides.
Hence, a polygon with 6 sides is called as hexagon.
Part b: The given polygon consists of 12 sides.
Hence, a polygon with 12 sides is called as dodecagon.
Part c: The given polygon consists of 10 sides.
Hence, a polygon with 10 sides is called as decagon.
