i need help: question = Which process will create a figure that is congruent to the figure shown?
Solution
Option A
Option A is Congruent because the size of the image is not tampered with, we only rotate, reflect and translate
Option A is correct
Option B
Option B is not congruent because there is a translation of scale factor of 1/2
Option C
Option C is not congruent because the distance between each points and the x-axis are tripled
Option D
Option D is not also congruent because the distance between each points and the x-axis are doubled
Hence, Option A is correct
Ms Martins has lockers for the students to store their things. The volume of the lockerd is 40 feet if the base is 4 by 2 feet how tall are the lockers
The volume of the lockerd is 40 feet ^3
If the base is 4 feet by 2 feet .
How tall are the lockers?
SOLUTION
Volume = Length x Width x Height
40 = L X 4 x 2
40 = L X 8
Divide both sides by 8
L = 5 feet
The locker is 5 feet
When rolling a pair of dice, find the probability that the sum is less than five and even.
In order to obtain the solution for this question, we need to find the sample space for 2 dice, which is given by:
As we can note, there are 36 events and there are 4 events which sum is less than five and even:
Since the probability is defined as the number of possible outcomes divided by the total number of outcomes, we have
[tex]P(\text{ sum less than 5 and even\rparen=}\frac{4}{36}[/tex]By simplifying this result, the answer is:

P=0.12 or P=12%A jar contains 10 purple marbles, 2 red marbles, and 5 blue marbles. What is the probability thatrandomly chosen marble is purple? Round the answer to the nearest hundredth of a percent.
EXPLANATION
Let's see the facts:
purple marbles = 10
red marbles = 2
blue marbles = 5
The probability formula is:
[tex]P(X)\text{ = }\frac{n\nu mber\text{ of favourable outcomes}}{\text{Total number of outcomes}}[/tex]The totl number of outcomes is 10+2+5 = 17 marbles
The number of favourable outcomes is equal to 10 because there are 10 purple marbles.
Then, the probability would be:
[tex]P(X)=\frac{10}{17}=\text{ 0.59}[/tex]Probability is 0.5882352941-->0.59 Rounded to the nearest hunderdth--------------->59%.
Answer: The probability is 59% (Rounded to the nearest hunderdth).
Please help me with this rectangle problem they always give me trouble
Hello there. To solve this question, we'll have to remember some properties about rectangles.
A rectangle is a quadrilateral polygon (that is, it has 4 right angles in its corners) and two parallel sides.
The special cases of quadrilaterals are the parallelogram, that has two parallel sides but the angles might not be right angles and the square, in which the sides are equal.
In the case of the rectangle, it has a side with length L and other side, that we call its width, with length W, as in the following drawing:
Its area A can be calculated taking the product between the length and the width, therefore:
[tex]A=L\cdot W[/tex]With this, we can solve this question.
It says that a rectangle is 15 ft longer than it is wide. Its area is 2700 ft². We have to determine its dimensions.
Say this rectangle has width W.
If this rectangle is 15 ft longer than it is wide, it means that
[tex]L=15+W[/tex]Now, we plug this values for the formula of area, knowing that A = 2700:
[tex]\begin{gathered} A=L\cdot W=(15+W)\cdot W \\ \end{gathered}[/tex]Apply the FOIL
[tex]2700=15W+W^2[/tex]In this case, we have a quadratic equation in W.
We'll solve it by completing the square, that is, finding a perfect trinomial square such that we can undo the binomial expansion and solve a simpler quadratic equation.
The binomial expansion (a + b)² gives us
[tex]a^2+2ab+b^2[/tex]So to find the b we need to complete the square, we start dividing the middle term by 2.
In the case of our equation, the middle term has coefficient 15, hence
[tex]b=\dfrac{15}{2}[/tex]Square the number and add it on both sides of the equation, such that
[tex]\begin{gathered} 2700+\left(\dfrac{15}{2}\right)^2=\left(\dfrac{15}{2}\right)^2+2\cdot\dfrac{15}{2}\cdot W+W^2 \\ \\ 2700+\dfrac{225}{4}=\dfrac{11025}{4}=\left(W+\dfrac{15}{2}\right)^2 \end{gathered}[/tex]Take the square root on both sides of the equation, knowing that 11025 = 105²
[tex]W+\dfrac{15}{2}=\sqrt{\dfrac{11025}{4}}=\sqrt{\left(\dfrac{105}{2}\right)^2}=\dfrac{105}{2}[/tex]Subtract 15/2 on both sides of the equation
[tex]W=\dfrac{105}{2}-\dfrac{15}{2}=\dfrac{105-15}{2}=\dfrac{90}{2}=45[/tex]Then we plug this value in the expression for L, hence we get:
[tex]L=15+W=15+45=60[/tex]Notice that multiplying the numbers, we'll get:
[tex]L\cdot W=60\cdot45=2700[/tex]That is exactly the area we had before.
Hence we say that its width equals 45 ft and its length equals 60 ft.

[tex]undefined[/tex]Seven years ago, Tom bought a house for $80,000, whichappreciated in value at 9% per year due to inflation. If Tomhas 48 more monthly payments of $500 to make to the bankon his 12% mortgage, find his present equity in the house.
The equity will be the value of the house today minus the present value of the remaining mortgage payments.
We can start with the value of the house. If the house was originally valued in $80,000 and appreciated at 9% per year during 7 seven years, we can calculate the present value as:
[tex]\begin{gathered} PV=80000\cdot(1+0.09)^7 \\ PV=80000\cdot1.09^7 \\ PV\approx80000\cdot1.828 \\ PV\approx146243.13 \end{gathered}[/tex]Now we can calculate the present value of the mortgage payments as an annuity.
The payments are monthly (m = 12), with an annual rate of 12% (r = 0.12). The amount paid monthly is $500 and there are 48 remaining payments (m*t = 48), so we can calculate the annuity as:
[tex]\begin{gathered} PV=M\cdot\frac{1-(1+\frac{r}{m})^{-m\cdot t}}{\frac{r}{m}} \\ PV=500\cdot\frac{1-(1+\frac{0.12}{12})^{-48}}{\frac{0.12}{12}} \\ PV=500\cdot\frac{1-(1.01)^{-48}}{0.01} \\ PV\approx500\cdot\frac{1-0.62026}{0.01} \\ PV\approx500\cdot\frac{0.37974}{0.01} \\ PV\approx500\cdot37.974 \\ PV\approx18986.98 \end{gathered}[/tex]Then, if we substract the mortgage present value from the present value of the house, we get the equity:
[tex]\begin{gathered} E=PV_{h\text{ouse}}-PV_{\text{mortgage}} \\ E=146243.13-18986.98 \\ E=127256.15 \end{gathered}[/tex]Answer: the present equity in the house is $127,256.15
Find the slope & y-intercept: x + 2y –9= 0
Explanation
we have
[tex]x+2y-9=0[/tex]to know the slope and the y-intercept the easiest way is by isolating y to get the slope-intercept form
Step 1
isolate y
[tex]\begin{gathered} x+2y-9=0 \\ add\text{9 in both sides} \\ x+2y-9+9=0+9 \\ x+2y=9 \\ \text{subtract x in both sides} \\ x+2y-x=9-x \\ 2y=9-x \\ \text{divide both sides by 2} \\ \frac{2y}{2}=\frac{9}{2}-\frac{x}{2} \\ y=-\frac{1}{2}x+\frac{9}{2} \end{gathered}[/tex]Hence
[tex]\begin{gathered} y=-\frac{1}{2}x+\frac{9}{2}\rightarrow y=mx+b \\ m\text{ is the slope} \\ b\text{ is the y intercept} \end{gathered}[/tex]therefore
[tex]\begin{gathered} \text{slope}=-\frac{1}{2} \\ y-\text{intercept =}\frac{9}{2} \end{gathered}[/tex]I hope this helps you
How do I solve this problem Lucy plans to spend between 50$ and 65$, inclusive, on packages of breads of charms. If she buys 5 packages of breads at $4.95 each, how many packages of charms at $6.55 can Lucy buy while staying within her budget?

Explanation
Step 1
Let
x= money Lucy spends
Lucy plans to spend between 50$ and 65$, replacing we have
[tex]50she buys 5 packages of bread at $4.95Step 2
find the money spent for buying 5 packages of bread
[tex]\begin{gathered} \text{cost}=\text{ 5 mu}ltipliedby4.95 \\ \text{cost}=5\cdot4.95=24.75 \\ \end{gathered}[/tex]Step 3

[tex]\begin{gathered} \text{balance}=65-24.75 \\ \text{balance}=40.25 \end{gathered}[/tex]Step 4
to find how many packages of charms at $6.55 she can buy,, just divide
[tex]\begin{gathered} \text{total of packages of charm= }\frac{40.25\text{ usd}}{6.55\frac{usd}{\text{pack}}} \\ \text{total of packages of charm=6.14 } \\ \end{gathered}[/tex]she can not buy 0.14 package, so she can buy 6 packages of charms
Karla says 4 and 4.7 would fall between V17 and 4O FactO Fib
First of all, we have to know the equivalent decimal number to each of them.
[tex]\begin{gathered} 4\frac{2}{3}=\frac{4\cdot3+2}{3}=\frac{12+2}{3}=\frac{14}{3}=4.66666\ldots \\ 4.7 \\ \sqrt[]{17}=4.12310\ldots \\ 4\frac{3}{4}=\frac{4\cdot4+3}{4}=\frac{16+3}{4}=\frac{19}{4}=4.75 \end{gathered}[/tex]Notice that the interval is from 4.12310... to 4.75.
You can observe that 4.7 falls into this interval, and 4.666... also falls into this interval.
Therefore, the numbers Karla indicated fall into the interval she mentioned.The answer is Fact.3. Lin is solving this system of equations:S 6x – 5y = 343x + 2y = 83. She starts by rearranging the second equation to isolate the y variable: y = 4 -1.5%. She then substituted the expression 4 - 1.5x for y in the first equation, asshown below:--6x – 5(4 – 1.5x) = 346x – 20 – 7.5x = 34-1.5x = 54x = -36y = 4 – 1.5xy = 4 - 1.5 • (-36)y = 58.
We are given the following system of equations:
[tex]\begin{gathered} 6x-5y=34,(1) \\ 3x+2y=8,(2) \end{gathered}[/tex]We are asked to verify if the point (-36, 58) is a solution to the system. To do that we will substitute the values x = -36 and y = 58 in both equations and both must be true.
Substituting in equation (1):
[tex]6(-36)-5(58)=34[/tex]Solving the left side we get:
[tex]-506=34[/tex]Since we don't get the same result on both sides this means that the point is not a solution.
Now, we will determine where was the mistake.
The first step is to solve for "y" in equation (2). To do that, we will subtract "3x" from both sides:
[tex]2y=8-3x[/tex]Now, we divide both sides by 2:
[tex]y=\frac{8}{2}-\frac{3}{2}x[/tex]Solving the operations:
[tex]y=4-1.5x[/tex]Now, we substitute this value in equation (1), we get:
[tex]6x-5(4-1.5x)=34[/tex]Now, we apply the distributive law on the parenthesis:
[tex]6x-20+7.5x=34[/tex]This is where the mistake is, since when applying the distributive law the product -5(-1.5x) is 7.5x and not -7.5x.

Let the Universal Set, S, have 52 elements. A and B are subsets of S. Set A contains 26 elements and SetB contains 14 elements. If the total number of elements in either A or B is 27, how many elements are inA but not in B?
ANSWER
Number of elements in A but not in B = 13
EXPLANATION
Step 1: Given that:
n(S) = 52
n(A) = 26
n(B) = 14
n(A U B) = 27
Step2: Using the Venn Diagram
Step 3: Determine the value of n(A n B)
n(A U B) = n(A) + n(B) - n(A n B)
27 = 26 + 14 - n(A n B)
n(A n B) = 40 - 27
n(A n B) = 13
Step 4: Determine the number of elements in A but not in B
n(A - B) = n(A) - n(AnB)
n(A - B) = 26 - 13
n(A - B) = 13
Hence, number of elements in A but not in B = 13
Two squares are shown in the diagram . The larger square has sides of length 5x units. The smaller square has an area equal to ⅑ of the larger square . Find the length of the sides or the smaller square. Give your answer in the form a/b where a,b ∊ ℕ
From the information given,
length of side of the larger square = 5x units
The area of a square is calculated by the faormula,
area = length of side^2
Thus,
Area of larger square = (5x)^2 = 25x^2
The smaller square has an area equal to ⅑ of the larger square. This means that the area of the smaller square is
Area of smaller square = 1/9 * 25x^2 = 25x^2/9
Length of the side of square = square root of area
Thus,
Length of the sides of the smaller square = square root of (25x^2/9)
Length of the sides of the smaller square = 5x/3

find an equation of the line passing through the pair points. write the equation in the form ax+by=c (-7,5),(-8,-9)
Given the pair of coordinates;
[tex]\begin{gathered} (-7,5) \\ (-8,-9) \end{gathered}[/tex]We would begin by first calculating the slope of the line.
This is given by the formula;
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]The variables are as follows;
[tex]\begin{gathered} (x_1,y_1)=(-7,5) \\ (x_2,y_2)=(-8,-9) \end{gathered}[/tex]We will now substitute these into the formula for finding the slope as shown below;

We shall use this value along with a set of coordinates to now determine the y-intercept.
Using the slope-intercept form of the equation we would have;
[tex]y=mx+b[/tex]We would now substitute for the following variables;
[tex]\begin{gathered} m=14 \\ (x,y)=(-7,5) \end{gathered}[/tex][tex]5=14(-7)+b[/tex][tex]5=-98+b[/tex]Add 98 to both sides of the equation;
[tex]103=b[/tex]We now have the values of m, and b.The equation in "slope-intercept form" would be;
[tex]y=14x+103[/tex]To convert this linear equation into the standard form which is;
[tex]Ax+By=C[/tex]We would move the term with variable x to the left side of the equation;
[tex]\begin{gathered} y=14x+103 \\ \text{Subtract 14x from both sides;} \\ y-14x=103 \end{gathered}[/tex]We can now re-write and we'll have;
[tex]-14x+y=103[/tex]Note that the coefficients of x and y (that is A and B) are integers and A is positive;
Therefore, we would have;
[tex]\begin{gathered} \text{Multiply all through by -1} \\ 14x-y=-103 \end{gathered}[/tex]The equation of the line passing through the points given expressed in standard form is;

The angles whose sum is equal to 180 degree are called linear pair of angle. So angle ABD and angle CBD are linear pair of angles.
Tiffany has volunteered 65 hours at a local hospital.This is 5 times the number of hours her friend Mario volunteered. Let m represent the number of hours that Mario volunteered. Which equation below can be used to determine the actual number of hours Mario volunteered?A 65 x 5 = mb 5 x m= 65C m +5=65d 5 ÷ m= 65e 5+ m =65
5 x m = 65
Explanations:The number of hours Tiffany volunteered = 65
The number of hours Mario volunteered = m
Tiffany volunteered 5 times the number of hours mario voluntered
Number of hours Tiffany volunteered = Number of hours Mario volunteered x 5
65 = m x 5
This can also be written as:
5 x m = 65
A coach buys a uniform and a basketball for each of the 12 players on the team. Each basketball costs $15. The coach spends a total of $756 for uniforms and basketballs. Write an equation that models the situation with u, the cost of one uniform.Find the cost of one uniform
Equation: 180 + 12u = 756
the cost of one uniform is $48
Explanation:Total number of players = 12
The cost per basketball = $15
Total cost for uniform and basket balls = $756
let the cost of each uniform = u
The equation becomes:
Total number of players(The cost per basketball ) + Total number of players( cost of each uniform)
12($15) + 12(u) = $756
180 + 12u = 756
To get u, we subtract 180 from both sides:
180 - 180 + 12u = 756 - 180
12u = 576
u = 576/12
u = 48
Hence, the cost of one uniform is $48

The volume of a rectangular prism can be calculated as follows:
Volume = Length x Width x Height
So, we can replace the volume by 798, the width by 8, and the length by 9.5:
798 = 8 x 9.5 x Height
798 = 76 x Height
Then, we can solve for the Height dividing both sides by 76:
798/76 = 76 x Height / 76
10.5 = Height
Therefore, the height of the prism is 10.5 cm
Solve this using either imaginary or complex numbers equation please!
Explanation: Here we will use two rules to be able to solve our question
First rule (complex numbers):
[tex]\sqrt[]{-1}=i[/tex]Second rule:
[tex]\sqrt[]{a\cdot b}=\sqrt[]{a}\cdot\sqrt[]{b}[/tex]Step 1: Now we can solve our expression as follows
Final answer: So the final answer is
[tex]i\cdot8\cdot\sqrt[]{3}[/tex]
