5 Clear Which number line best represents the solution to the inequality 18x + 3 < 48?
Answers
Answer:
D
Step-by-step explanation:
you must solve first
18x < 45
x < 2.5
the number line will have an arrow with an open circle since it does not include 2.5. the line will head towards 0 and negatives since it's less than 2.5 so your answer is D

roblem 1.12: calculate the average volume per molecule for an ideal gas at room temperature and atmospheric pressure. then take the cube root to get an estimate of the average distance between molecules. how does this distance compare to the size of a molecule like { n } { 2 }n 2 or { h } { 2 }oh 2 o?
Answers
An ideal gas follows the ideal gas law stating PV = nRT. Obtain the average volume/mole by solving for V/n. Divide both sides by Avogadro’s constant Na. Multiplying n and Na gives the number of molecules N. V/N is the average volume/molecule. 250C is the room temperature = 298.15K. The atmospheric pressure is 101325 Pa or 1 atm. Each molecule in a gas is spaced evenly and placed in a lattice. To obtain the space taken up by a cube, find the cube root of V/N to obtain the average intermolecular distance. For small molecules such as N2 or H2, the angstroms order is 10^(-10) m. The intermolecular distance is about 10 times the small molecules.
P V = nRT
V⁄n=RT⁄P
V⁄(nNa )=RT⁄(PNa )
V⁄N=((8.314 J/(mol.K))(298.15K))/((101325Pa)(6.02×10^23 molecules/mol))≈4.06×10^23 m^3/molecule
∛(V/N)≈3.44×10^(-9) m = 3.44 nm
The intermolecular distance is about 10 times the small molecules.

There are 5280 feet in a mile and 60 minutes in an hour (needless to say). How fast is a car going 30 miles per hour traveling in feet per minute?
(Please help me)
Answers
Answer:
2640 feet in a minute.
Step-by-step explanation:
Since the car is going 30 miles per hour, and there are 5280 feet in one mile, you would multiply 30 by 5280.
30 * 5280 = 158400
So 154800 feet = 30 miles.
Since you want to find out how fast a car going 30 miles per hour is traveling in feet per a minute, you would divide 154800 feet by 60, since there are 60 minutes in an hour.
154800 / 60 = 2640.
So 2640 feet in a minute.
If you want to check this, you can do 2640 * 60, which indeed equals 154800.
Hope this helps.

If 4x--6=14, then 2x-5=5.
If 2x -- 5≠5, then 4x--6≠14.
If 4x - 6≠14, then 2x - 5≠5.
Answers
Answer:
We conclude that:
If 4x - 6≠4, then 2x–5≠5 is the contrapositive of a conditional statement if 2x -5=5, then 4x-6=14.Step-by-step explanation:
We know that the contrapositive of a conditional statement of the form "If p then q" is termed as "If ~q then ~p".In other words, it is symbolically represented as:
' ~q ~p is the contrapositive of p q 'For example, the contrapositive of "If there is a snow outside, then they cancel the event" is "If they do not cancel the event, then it would not be snow outside."
Given
p: 2x -5=5q: 4x-6=14As the contrapositive of a conditional statement of the form "If p then q" is termed as "If ~q then ~p
Therefore, we conclude that:
If 4x - 6≠4, then 2x–5≠5 is the contrapositive of a conditional statement if 2x -5=5, then 4x-6=14.A plane travels 3,625.26 miles in 6.9 hours. What is the plane’s unit rate?

The amount of money left after purchasing the bike is $17.32
How to calculate the amount of money left ?The cost of the new bike is $142.68
I need to save for the new bike and i decided to mow the neighbour's yard
The money paid is $40, this will be done for 4 weeks
At the end of the four weeks, the money i will get can be calculated as follows
= 40 × 4
= 160
To calculate the money left, let's subtract the cost of the bike from 160
= 160 - 142.68
= 17.32
Hence the amount of money left after buying the bike is $17.32

Answer:the answer is a
Step-by-step explanation:
The expression 2(14x - 3y + 28x + 12.2 - 5y - 17.5) is equivalent to the expression 84x - 16y -10.6 option (A) is correct.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
We have an expression:
= 2(14x - 3y + 28x + 12.2 - 5y - 17.5)
= 28x - 6y + 56x + 24.4 - 10y - 35
Adding like terms
= 84x - 16y -10.6
Thus, the expression 2(14x - 3y + 28x + 12.2 - 5y - 17.5) is equivalent to the expression 84x - 16y -10.6 option (A) is correct.
