Answer: 6 miles
Step-by-step explanation:
From the question, we are informed that the taxi charges $4.75 for the first mile, and then $2.25 for each mile after that and that the total charge is $18.25.
The distance of Sara's taxi ride to the movie would be:
4.75 + 2.25m = 18.25
where,
m = number of miles
4.75 + 2.25m = 18.25
2.25m = 18.25 - 4.75
2.25m = 13.5
m = 13.5 / 2.25
m = 6 miles
The answer is 6 miles.
The length of “L” is 14.

Answer:
A.
Step-by-step explanation:
you have to find the discriminant
b²-4ac for each equation
if discriminant < 0 no real solutions because will be negative under the squareroot whhan you try to find the roots
if discriminant = 0 there is only one solution
if discriminant > 0 two real solutions
for your given problems
A. discriminant =(-2)²-4*2*15 will be negative
It costs $.50 to mail a letter of that size.
All letters that are under 3.5 oz take only one stamp to ship. Since 2.7 is less, it would cost only $.50
As we know,
So, we can infer that :
Now, let's calculate the mass of gases in each case :
<h3>Case A : Hydrogen ~</h3>
or
<h3>Case B : Helium ~ </h3>
or
<h3>Case C : Nitrogen ~ </h3>
or
So, the arrangement of masses from least to greatest is :
- (1.) Hydrogen < (2.) Helium < (3.) Nitrogen
