8 days because 4/5 = 8/10 and he is using 1/10 a day.
Answer:
That's all you're doing is writing the equation for two lines and finding out where they intersect. The slope is how much the price is increasing or decreasing and the y-intercept is where the price is starting at.
x = number of hours
y = mx + b = 0.12(x + 3) + 15.21 {It's (x + 3) because we have to add the 3 hours between 9 and noon}
y = mx + b = -0.11x + 15.96 {The slope is negative because the price is decreasing}
Set them equal to each other
0.12(x+3) + 15.21 = -0.11x + 15.96
Now solve for x
0.12x + 0.36 + 15.21 = -0.11x + 15.96
0.12x + 15.57 = -0.11x + 15.96
0.12x + 0.11x = 15.96 - 15.57
0.23x = 0.39
x = 0.38 / 0.23 = 1.7 hours
Convert 0.7 into minutes
0.7 hours * (60 min / 1 hour) = 42 min
So the prices are the same 1 hour and 42 min after noon, which is 1:42 PM

Answer:
1.315%
Step-by-step explanation:
Given:
Prices:
Year 1 =old price =$95
Year 2 = new price = $96.25
The inflation rate is the difference in price between two Given period :
Inflation rate :
(Change in price / old price) * 100%
((New price - old price) / old price) * 100%
((96.25 - 95) / 96) * 100%
= (1.25 / 95) * 100%
= 0.0131578 * 100%
= 1.315%
Answer:
1/2
Step-by-step explanation:
to solve this equation you must find the greatest common factor or gcf to make the denominators the same
that happens to be 6
so
-4 5/6 + 5 2/6
then you add
you can break them up at add them like this
(-4 + 5) + (-5/6 + 2/6)
1 + -3/6
-3/6 is also -1/2
1 + -1/2
1/2
that is your answer
Answer:
D. 2x - 2 + 3x
Step-by-step explanation:
First, add 2x and 3x. Then you get 5x. Then you get the equivalent expression 5x-2.
