Answer:
It took the cell phone 4.15 seconds to reach the ground
Step-by-step explanation:
The formula is 
, where t is the time and h is the height
The height of that the cell phone dropped from it is 275 feet above the ground
∴ h = 275
- Substitute the value of h in the formula to find t
∵ 
∴ 
- Change it to decimal
∴ t = 4.15 seconds to the nearest 2 decimal places
It took the cell phone 4.15 seconds to reach the ground
-6 is less than or equal to 2x - 12 is less than 20
Answer:
x=y=1/2 thus nearest thousandth term is 0
Step-by-step explanation:
x=1/2
y=x
y=1/2
nearest thousand =0 for 1/2
Answer:
See below
Step-by-step explanation:
Let's suppose you're getting a new phone plan. The phone plan charges a flat fee of $5 and costs $9 a month. How can we represent this relationship?
Since $5 is a flat fee, it doesn't change based on how many months you've had the plan because it always remains $5, so this is our y-intercept.
Because the plan costs $9 a month, this represents our rate of change, or slope, showing that every month you have the plan, you multiply by $9.
So, we can show this as y=9x+5 where x is the number of months of the phone plan and y is the cost of the phone plan given x amount of months
Now, what if you wanted to know how much the phone plan would cost after 4 months?
Simple enough, we can just substitute x=4 into our equation and get y=9(4)+5=36+5=41. So, getting the phone plan for 4 months costs $41.
Let's take this the other way around. What if we wanted to figure out how many months of the phone plan are covered by $50?
We would then substitute y=50 into our equation and solve for x:
y=9x+5
50=9x+5
45=9x
5=x
This would mean $50 would cover 5 months of the phone plan.
All in all, these are real-life examples of algebra.
Answer:
<u><em>He made a loss of 6.67%</em></u>
Step-by-step explanation:
Loss percentage = 
Loss = 50
Cost price = 750
Hence, Loss percentage=
=
= 6.66 %
He made a loss of 6.6666%.
This amount can be rounded up to 6.67%
