Answer:
The more thermal energy added, the greater the attraction between molecules. The molecules gain kinetic energy, move farther apart, and become a gas. The water molecules become packed closer together, and their temperature increases. Each water molecule gives up kinetic energy and eventually stops moving.

Today, everything at a store is on sale. The store offers a 20% discount.
a) The regular price of a T-shirt is $18. What is the discount price?
b) If the regular price of an item is dollars, what is the discount price in dollars? Write an expression.
c) The discount price of a hat is $18. What is the regular price?
Answer:
a. $14.4
b. $18 • .2 = $3.6
c. $21.6
Step-by-step explanation:
a. Make the 20% a decimal, and multiply by the regular price. Then, subtract that and you'll get the discounted price.
18 • .2 = 3.6
18-3.6 = $14.4
b. Use the equation multiplying the 20% as a fraction here.
c. Multiply $18 by .2 (the discount). Then, add that to the discount price ($18).
18 • .2 = 3.6
3.6 + 18 = $21.6

Quartiles are the values that divide a list of numbers into quarters: Put the list of numbers in order. Then cut the list into four equal parts. The Quartiles are at the "cuts"
...
Box and Whisker Plot
Quartile 1 (Q1) = (4+4)/2 = 4.
Quartile 2 (Q2) = (10+11)/2 = 10.5.
Quartile 3 (Q3) = (14+16)/2 = 15.
Answer:
The second 6
Step-by-step explanation:
So first quartile is the middle number in the beginning section after the middle number if that makes sense. The middle number is 10 so we break it into halves around that. The middle number in the first half is the second 6

Factor – 1/2 out of -1/2x+6
What is the factored expression of this
Answer:
-1/2(x-12)
Step-by-step explanation:
Since you need to factor -1/2 out of the given expression, you can say that
-1/2x+6 is equal to
-1/2(x-12)
Answer: [tex]-\frac{1}{2}(x-12)[/tex]
==================================================
Explanation:
The terms of [tex]-\frac{1}{2}x+6[/tex] are [tex]-\frac{1}{2}x[/tex] and [tex]6[/tex]
Divide each term by -1/2 to factor out the -1/2
If we divide [tex]-\frac{1}{2}x[/tex] over -1/2, then we'll get x. Basically the -1/2 terms cancel.
If we divide 6 over -1/2, we get -12. It might help to think of it as 6/(-0.5) = -12.
So overall we have [tex]-\frac{1}{2}x+6 = -\frac{1}{2}(x-12)[/tex]
You can use the distribution property to check the answer.

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is the exponential function as -
f(x) = (0.5)ˣ + 4
An exponential function is of the form → f(x) = eˣ.The given function is -
f(x) = (1/2)ˣ + 4
The graph of the function is attached.
Therefore, the graph of the function given is attached at the end.

Henry divided his socks into five groups. Let s represent the total number of socks. Which expression and solution represent the number of socks in each group if s=20?
A. S/5; when s=20, the number of socks in each group is 4.
B. S/5; when s=20, the number of socks in each group is 15.
C. S-5; when s=20, the number of socks in each group is 4.
D. s-5; when s=20, the number of socks in each group is 15.
Answer:
A. 4 socks per group and S/5
Step-by-step explanation:
20 total # of socks ÷ 5 groups = 4 socks per group
So A. is correct.

Answer: y= x +3
1) find slope using rise over run. Find your coordinates. I used (-3,0) and (0,3). Rise over run with these values : 3-0/0- -3. You should get 1 as a slope after adding and simplifying. Y=1x+b is your equation. Plug in your y and x values to the equation: 3= 0x1 +b. Multiply: 3= 0+b. B is 3( your y intercept). The equation is y=x+3
