Answer:
100
Step-by-step explanation:
We know that the angle of a straight line is 180°.
So we know that (5x-5) + (2x+10) = 180
We will then solve for x
5x - 5 + 2x + 10 = 180
7x + 5 = 180
7x = 175
x = 25 (just an explanation of how we get 25)
To get angle 1, we will then plug in x=25 into the first equation to get
5(25)-5 = 125-5 = 120°
Answer:
60
Step-by-step explanation:
If 36 is the result of reducing the number by 40% then 36 is 60% of the number you can then division by 0.6 to get 60. 60. 100–40=60
Answer:
So after 7 year price of the laptop will be less than $1000
Step-by-step explanation:
We have given price of the laptop is $4500
Its price is 80% of if its value in every next year
So depreciation rate = 100 - 80 =20%
For depreciation we know that
Here V is final value and P is present value
So 
Taking log both side
n = 6.74
So after 6.74 year the price of the laptop will be less than $1000
