Answer:
69.45 m to the nearest hundredth.
Step-by-step explanation:
I guees you want the length of one side.
A square has 4 sides of equal length and the area = s^2 where s = length of each side.
So the length of a side of a square of area 4823
= √(4823)
= 69.4478 m.
Answer: you will save with plan B for miles greater than 153.8 miles.
Step-by-step explanation:
Let x represent the number of miles driven with either plans per day.
Plan A: 30 dollars per day and 13 cents per mile. Converting cents to dollars, it becomes 13/100 = $0.13. It means that the total cost of driving x miles with plan A is
30 + 0.13x
Plan B: 50 dollars per day with free unlimited mileage. It means that the total cost of driving x miles with plan B is 50 dollars
For you to save money with plan B, it means that the number of miles would be
50 < 30 + 0.13x
50 - 30 < 0.13x
20 < 0.13x
0.13x > 20
x > 20/0.13
x > 153.8
If I did my math right the answer would be X = -5/4
hope this helps!
Answer: n= 4.25
Step-by-step explanation:
First, distribute the -4.
108= 12n+20n-28
Next, simplify.
108= 32n-28
Isolate n by adding 28 to both sides.
136= 32n
Divide both sides by 32 to get n by itself.
n=4.25
