If you are a visual learner, draw a circle and split it into 4 equal pizza slices. Shade 1 out of the 4 to represent 1/4.

Put another way: you have 3 friends who get 1/4 of a pizza each. That shades 3 out of the 4 total slices to get 3/4.
Due to temporary tax cuts in 2010, a person with typical deductions earning $50,000 per year would have saved 2% of their income plus $850 in federal taxes. How much money did a typical person save?
Answers
If the person earns $50,000, we must find how much is 2% of that and then add it to $850. Then we would have how much a typical person saves.
First let's find 2% of $50,000
[tex]\begin{gathered} 2\%\text{ of }50000=\frac{2}{100}\cdot500000=\frac{2\cdot50000}{100}=\frac{100000}{100}=1000 \\ \\ \\ \end{gathered}[/tex]Therefore 2% of $50,000 is $1000. Now we add it to $850 and we get

Im stuck on question 5-91 in cpm geometry the question asks me to find the area of a triangle... I figured out the 30 60 90's are but i still have triangle left over ill send a photo of the triangle
Answers
Answer
Area of the triangle = 72 square units
Explanation
For a triangle whose two sides (a and b) are given, and an angle that exists between them is also given, the area of that triangle is given as
Area of the triangle = ½ ab Sin θ
For this question,
a = 12 units
b = 24 units
θ = 30°
Area of the triangle = ½ ab Sin θ
Area of the triangle = ½ (12) (24) (Sin 30°)
Sin 30° = 0.5
Area of the triangle = ½ (12) (24) (Sin 30°)
Area of the triangle = ½ (12) (24) (0.5) = 72 square units

change the height for Ramp 2 to make a smooth slide
Answers
First answer:
If you look carefully to the measures of the three triangles that are the ramps of the exercise, you will notice they are similar after comparing them.
• Ratio of Ramp 1 = 2/3
,• Ratio of Ramp 2 = 4/6
,• Ratio of Ramp 3 = 6/9
Second answer
The information is given on the image and we can calculate the missing measures for make a smooth slide:
• Ramp 1 - Base 10 - Height 12
,• Ramp 2 - Base 15 - Height 18
,• Ramp 3 - Base 30 - Height 36
We used the ratio 2/3 for answering the first question, now we have the ratio
5/6, as follows:
• Ramp 1 - 5/6 * 2/2 = 10/12
,• Ramp 2 - 5/6 * 3/3 = 15/18
,• Ramp 3 - 5/6 * 6/6 = 30/36

Answers
The measure of three angles of triangular backyard are 28°, 31° and 121°.
Given that, a home has a triangular backyard.
What is the angle sum property of a triangle?Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.
Let the measure of first angle be x.
The second angel of the triangle is 3 more than the first angel = x+3
The third angel is 9 more than four times the first angel = 4x+9
Using angle sum property of a triangle
x+x+3+4x+9 = 180°
⇒ 6x + 12 = 180
⇒ 6x = 168
⇒ x = 28°
So, x+3 = 31° and 4x+9 = 121°
Therefore, the measure of three angles of triangular backyard are 28°, 31° and 121°.

Find the value of a.
Answers
The value of a is √10/2 if |x| = 2√2 and a|x| = 2√5 in the given Functions respectively.
What is function?Functions are the foundation of calculus in mathematics. The functions are the various types of relationships. In mathematics, a function is represented as a rule that produces a unique output for each input x.
In mathematics, mapping or transformation is used to denote a function. These functions are usually represented by letters like f, g, and h. The domain is defined as the set of all possible values for which the function can be defined.
We have given that f(x) = |x|
Where x is hypotenuse the triangle made by the line
The formula for hypotenuse = c² = a² + b²
Here each side = 2 units
so hypotenuse is
c² = 4² + 4²
c² = 16 + 16
c² = 32
c = 4√2
Thus, f(x) = 2√2
In f(x) = a|x|
The blue lines with the base and side also makes a right angles triangle and the blue line is the hypotenuse
c² = 4² + 2²
c² = 16 + 4
c² = 20
c = 2√5
Thus, f(x) = 2√5
Now, if |x| = 2√2 and a|x| = 2√5
Taking |x| in common we get the equation
2√2 = (2√5)/a
a = (2√5)/(2√2)
a = √5/√2
a = √10/2
Thus, the value of a is √10/2 if |x| = 2√2 and a|x| = 2√5 in the given Functions respectively.

Answers
Explanation:
We need to check out each of the options to determine which of the statements are true:
The given function: y = |x| - 2
a) The symbol '| |' means absolute. So any number you put in it either positive or negative number,becomes positive after it is removed.
For example: if x = -2, y = |-2| - 2 = 2 -2 = 0
if x = -1, y = |-1| -2 = 1 -2 = -1
Hence from the example above, the value of the function can be negative.
Statement is wrong
b) Yes, the graph has a V shape: (statement is correct)
c) For the output to be 0, it means y = 0
Let's find out the value of x when y= 0
y = |x| -2
0 = |x| -2
0 + 2 = |x|
|x| = 2
|x| = x or -x
From the above we have only one x value (the input) which is 2
Statement is correct
d) For the output to be 5, y = 5
5 = |x| -2
|x| = -2 -5
|x| = -7
|x| = x or -x
x = -7 or -x = -7
x = -7 or x = 7

Answers
The general equation of a circle with centre (h,k) and radius r is given as
[tex]\begin{gathered} (x-h)^2+(y-k)^2=r^2 \\ \text{where,} \\ (h,k)=(10,4) \\ r=4 \end{gathered}[/tex]By substitution, we will have,
[tex]\begin{gathered} (x-10)^2+(y-4)^2=4^2 \\ =(x-10)^2+(y-4)^2=16 \end{gathered}[/tex]Hence,
The correct answer is OPTION A
In parallelogram FGHJ if m^GHJ=55° find m ^ FGH. I
Answers
Given:
[tex]m\angle GHJ=55^o\text{ and m}\angle FGH=x^o[/tex]Recall that the adjacent angles of the parallelogram are supplementary.
[tex]\begin{gathered} m\angle GHJ\text{ and m}\angle FGH\text{ are adjacent angles of the given parallelogram and these are supplementary.} \\ \end{gathered}[/tex]We know that the sum of the supplementary angles is 180 degrees.
[tex]m\angle GHJ+\text{m}\angle FGH=180^o[/tex][tex]55^o+x^o=180^o[/tex][tex]x^o=180^o-55^o[/tex][tex]x^o=125^o[/tex]Hence the answer is
[tex]\text{ m}\angle FGH=125^o[/tex]
