Two quarters and one dime = 60 cents, and she's dividing it equally between three people (Kylie and two friends), and 60 divided by 3 is 20, so each person would get 20 cents.
Part B:
No, because 2/10 of the money means 2/10 of 60, which is 12, and each person gets 20 cents, not 12 cents.

Plane 1: 12 game plan cost=$192
Cost of single game= 192/12 =$16
Plane 2: 28 game plan cost=$420
Cost of single game= 420/28 = $15
So plan 2 ( 28 games for $420) is the better plan .
Answer: 28 games for $420 is the better plan.
$192 / 12 = $16 a game
$420 / 28 = $15 a game
The 28-game plan is better value per game.
Use the given conditional statement to determine the converse and inverse statements. If a line is vertical, then it has undefined slope.
Answers
1.1) Inverse statement: negating the hypothesis and the conclusion of the original statement, i.e.:
conditional statement: p → q
inverse: ~p → ~q (the symbol ~ means the negation)
1.2) Converse statement: switching the hypothesis and the conclusion of the conditional statement, i.e.:
conditional statement: p → q
converse: q → p
2) converse of the given statement
conditional: If a line is vertical, then it has undefined slope.
converse: switch the hypothesis and the conclusion
if a line has undefined slope, then it is vertical <------- answer
3) Inverse of the given statement
conditional: if a line is vertical, then it has undefined slope.

A leaky pool loses 2 1/4 inches of water each day. Jermaine and Mildred are asked to determine the change in the amount of water in the pool over 5 days.
Jermaine’s Solution Mildred’s Solution
5(-2 1/4) 5(-2 1/4)
5(-2 -1/4) 5(-2 -1/4)
-10 -1/4 -10 -5/4
-10 1/4 -11 1/4
Which describes the reasoning used to determine whose solution is correct?
A. Jermaine is correct because -10 -1/4 equals -10 1/4.
B.Jermaine is correct because he distributed 5 correctly.
C.Mildred is correct because she multiplied 5 by –2 but not by -1/4.
D.Mildred is correct because she distributed 5 correctly.
Answers
5(-2 1/4) = 5(-2 + -1/4) = 5(-2) + 5(-1/4) = -10 + -5/4 = -10 + -1 1/4 = -11 1/4
Answer: D. Mildred is correct because she distributed 5 correctly.
Step-by-step explanation:
Since, the loss of water in one day = [tex]2\frac{1}{4}\text{ inches}[/tex]
⇒ The loss of water in 5 days = [tex]5(2\frac{1}{4})\text{ inches}[/tex]
⇒ The loss can be written with negative sign,
Thus, the expression that shows the changes in quantity of water in 5 days,
[tex]-5(2\frac{1}{4})[/tex]
[tex]=-5(2+\frac{1}{4})[/tex]
[tex]=5(-2-\frac{1}{4})[/tex]
[tex]=-10-\frac{5}{4}[/tex]
[tex]=-10-1\frac{1}{4}[/tex]
[tex]=-10-1-\frac{1}{4}[/tex]
[tex]=-11-\frac{1}{4}[/tex]
[tex]=-11\frac{1}{4}[/tex]
Since, the above steps are similar to that of Mildred's solution,
⇒ Mildred is correct.
Also, By the above explanation it is clear that jermaine incorrectly distribute 5 in his third steps.
⇒ Option D is correct.

In m + 8, the variable m can have any value. Tell whether each statement is true or false. Then explsin your reasoning.
Answers
In algebra, the variable 'm' in the expression 'm + 8' can indeed take on any value; therefore, the statement is true because variables are meant to be placeholders for a wide range of numbers.
Explanation:In the expression m + 8, it is true that the variable m can have any value, which means that this expression does not impose any restrictions on the possible values of m. This type of statement involving a variable is common in mathematics, particularly in algebra where variables represent unknown quantities that can take on various values.
When evaluating statements for truth or false, the statement 'in m + 8, the variable m can have any value' is true. Variables, by their nature, are symbols that can represent any number, so unless specific limitations are given, we assume variables to have the full set of numbers (real numbers, integers, etc.) as potential values.

Sonia makes a wooden frame around a square picture. The frame is made of 4 congruent trapezoids. The shorter base is 9 in., the longer base is 12 in., and the height is 1.5 in. What is the area of the picture frame? PLEASE tell me why the answer is that answer.
Answers
Final answer:
The area of Sonia's picture frame is determined by calculating the area of one trapezoid with given dimensions and multiplying by four. The area of each trapezoid is 15.75 square inches, resulting in a total frame area of 63 square inches.
Explanation:
The area of Sonia's picture frame can be calculated by finding the area of one of the congruent trapezoids and then multiplying it by four, since there are four trapezoids making up the entire frame. The formula to calculate the area of a trapezoid is: Area = (1/2) × (base1 + base2) × height. In this case, the shorter base (base1) is 9 inches, the longer base (base2) is 12 inches, and the height is 1.5 inches. Substituting these values into the formula gives us: Area of one trapezoid = (1/2) × (9 in + 12 in) × 1.5 in = (1/2) × 21 in × 1.5 in = 15.75 in2. The total area of the frame is then four times this amount, which equals 63 in2. This answer explains how to calculate the area of a trapezoid and then applies the concept to find the total frame area.

If there is more than one unknown, additional equations may be necessary.Solve the simultaneous equations for the unknowns.Eliminate terms wherever possible to simplify the algebra.Substitute the known quantities, along with their units, into the appropriate equation and obtain numerical solutions complete with units.Check the answer to see if it is reasonable: Does it make sense?The seventh step is to take the square root of both sides. The eighth step is to isolate x by subtracting [tex]\(\frac{B}{2a}\)[/tex]. The ninth step simplifies the expression.
The seventh step is:
7. Take the square root of both sides to isolate x:
[tex]\[ x + \frac{B}{2a} = \pm \sqrt{\frac{b^2 - 4ac}{4a^2}} \][/tex]
The eighth step is:
8. Solve for x by subtracting [tex]\(\frac{B}{2a}\)[/tex] from both sides:
[tex]\[ x = -\frac{B}{2a} \pm \sqrt{\frac{b^2 - 4ac}{4a^2}} \][/tex]
The ninth step is:
9. Simplify and solve for x:
[tex]\[ x = \frac{-B \pm \sqrt{b^2 - 4ac}}{2a} \][/tex]
This is the quadratic formula, which gives the solutions for the equation [tex]\( ax^2 + bx + c = 0 \)[/tex].

247.52 centimeters.
To find this answer, you have to find 91% of Robert Wadlow's height. To do that, you multiply 272 by 0.91, which gives you the height of Zeng Jinlian.
Here we just need to find .91 of 272cm to find her height,
so we take .91percent * 272cm= 247.52 rounded to nearest cm is 248cm tall

the local chess club has 60 member. 24 of them are younger than twenty. what percent of members of the chess club are younger than 20
Answers
24/60
Simplify by dividing the numerator and denominator by the GCF, 12:
2/5
Percentages are parts of 100, so we want to get 100 in the denominator to find the percentage. 100 / 5 = 20, multiply numerator and denominator by 20:
40/100
This is 40 parts of 100 or 40%.
So 40% of the members of the chess club are younger than 20.
The local chess club has 60 members and 24 of the members are younger than 20. What percent of members are younger than 20?
The fraction [tex]\frac{24}{60}[/tex] represents the 24 members that are younger than 20 out of all the members in the club.
To find out what percent of members are younger than 20, we can turn [tex]\frac{24}{60}[/tex] into a percent.
We can first reduce this fraction by dividing both the numerator and denominator by the Greatest Common Factor of 24 and 60 using 12.
24 ÷ 12 = 2
60 ÷ 12 = 5
Now, we have our reduced fraction which is [tex]\frac{2}{5}[/tex].
2 ÷ 5 = 0.4
0.4 × 100 = 40%
Therefore, 40% of the chess club members were under 20.
The formula represents the surface area S of a cube with side lengths of X
S=6x^2
Answers
Rationalize the denominator by multiplying by the square root of 6:
[tex]\frac{\sqrt{S}*\sqrt{6}}{\sqrt{6}*\sqrt{6}}=x \\ \\ \frac{\sqrt{S*6}}{\sqrt{6*6}}=x \\ \\ \frac{\sqrt{6S}}{6}=x[/tex]
The formula S=6x^2 calculates the surface area S of a cube. It multiplies the square of the side length X by 6 since a cube has six faces. An example with X=2 gives the surface area S as 24 square units.
Explanation:The formula S=6x^2 in Mathematics is used to calculate the surface area of a cube. Each face of a cube is a square, and since a cube has 6 faces, this is why the surface area S is calculated as 6 times the square of the side length X. As an example if we have a cube with side length of 2 units (X=2), we can substitute X in the formula, giving us S=6*(2^2) = 24 square units, which is the total surface area of the cube.
