Answer: 3%
Step-by-step explanation:
S.I = ptr / 100
Interest = 4515 - 4500
Interest = 15
time = 4 months = 4/12 years = 1/3 years
substituting each value into the equation to find rate , we have
15 = 4500 x 1/3 x r / 100
1500 = 4500 x 1/3 x r
3(4500) = 4500r
r = 3(4500) / 4500
r = 3%

Please help! An angle measuring 3.5 radians is equal to which of the angle measures given below? (Use 3.4 for pi). Check ALL that apply.
A) 630 degrees
B) 200.64 degrees
C) 200 degrees 38'24"
D) 210 degrees
The measure of the angle is;
200.64 degrees ⇒ B
200 degrees 38' 24" ⇒ C
Step-by-step explanation:
To convert the measure of an angle from degrees to radians or from radians to degrees use these rules
If the measure of the angle is x°, then multiply it by [tex]\frac{\pi }{180}[/tex] to find its measure in radiansIf the measure of the angle is x radians, then multiply it by [tex]\frac{180}{\pi }[/tex] to find its measure in degrees∵ The measure of an angle is 3.5 radians
- We need to change its measure to degree, use the 2nd rule
∵ π = 3.14
∴ Its measure in degree = [tex](3.5).(\frac{180}{3.14})[/tex]
∴ Its measure in degree = 200.64°
To find its measure in degree, minutes and seconds, multiply the number before decimal point by 60 to find the number of minutes
∵ 1° = 60'
∵ 0.64 × 60 = 38.4
- That means the number of minutes is 38
∵ 1' = 60"
∵ 0.4 × 60 = 24
- That means the number of seconds is 24
∴ The measure of the angle is 200° 38' 24"
The measure of the angle is;
200.64 degrees
200 degrees 38' 24"

because if you should expand 4(3y - 2) by multiplying each value within the bracket by 4, you will have 12y - 8
A middle class family with two working parent receives $100,000 annually. About 40% is withheld (taken out of their paycheck for income tax and retirement plan). What is this family monthly income after the 40% is taken off?
Answer:
$60,000
Step-by-step explanation:
100,000 / 10 = 10,000, 10- 4=6, 10,000 * 6 = 60,000
To determine the monthly income of a family after 40% is withheld from a $100,000 annual income, subtract the amount withheld ($40,000) from the annual income and divide by 12, yielding a monthly income of $5,000.
To calculate the monthly income after taxes for the family, we first need to determine the amount withheld from the annual income for taxes and retirement plans. With an annual income of $100,000 and 40% being withheld, we do the following calculation:
Amount withheld: $100,000 times 0.40 = $40,000After-tax annual income: $100,000 - $40,000 = $60,000Monthly income after tax: $60,000 / 12 months = $5,000Therefore, the family's monthly income after the 40% is taken off would be $5,000.

1.) Write f(x) = x2 - 6x + 8 in vertex form
Answer:
f(x) = (x - 3)² - 1
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square
Add/subtract ( half the coefficient of the x- term )² to x² - 6x
f(x) = x² + 2(- 3)x + 9 - 9 + 8
= (x - 3)² - 1

Given ΔFGH ~ ΔLMN, which must be true? Select all that apply.
A. FGLM=FHLN
B. FH ~ LN
C. m∠Fm∠L=m∠Gm∠M
D. GH≅MN
E. m∠H≅m∠N
In similar triangles ΔFGH and ΔLMN, only the corresponding angles are congruent (thus ∠H ≅ ∠N). The sides are proportionate, not necessarily congruent. Other listed options are either incorrect or unclear due to potential misinterpretations or typographical errors.
Explanation:Given that triangles ΔFGH and ΔLMN are similar (ΔFGH ~ ΔLMN), the following must be true based on the concept of similar triangles:
The corresponding angles are congruent, which means that ∠F ≅ ∠L, ∠G ≅ ∠M, and ∠H ≅ ∠N (option E). The corresponding sides are proportionate, meaning that the ratio of corresponding sides (FG/LM, GH/MN, and FH/LN) are equal. However, this doesn't mean that the corresponding sides are congruent. Hence option D is not necessarily true. Option B implies that lines FH and LN are similar, which is not a concept in geometry. Hence it's incorrect. Option A is incorrect because it seems to imply congruence of some unspecified aspect of the triangles, which is not a guaranteed condition under triangle similarity. Option C's meaning is unclear due to potential typographical error or misinterpretation.Learn more about Similar Triangles here:

The price of a movie ticket increased from $25 to $30 What does this mean about the new price?
Choose the correct answer below
O A. The new price is 80% of the old price because 25-30 s 8. or 80%
OB. The new price is 80% of the old price because the price decreases by 20%, which is subtracted from 100%
OC. The new price is 125% of the old price because the price increases by $5, which is multiplied by the original price 5x 25 = 125%
O D. The new price is 20% of the old price because the price increases by 55 and 55 is 20% of $25
OE. The new price is 120% of the old price because the price increases by 20%, which is added to 100%
O F. The new price is 750% of the old price because 25 x 30 = 750
The correct option will the new price is 120% of the old one because the price increases by 20%, which is added to 100%.
What is percent of change?Percent of change is determined by the difference between the two values divided by the orginal one, then multiplied by 100.
i.e. percent of change=(change in value/original value)*100
So according to the asked question,
old value of the shoes=$25
new value of the shoes=$30
change in value=30-25=$5
percent of change=((30-25)/25)*100=20%
hence price increases by 20%.
If the old price is 100 and price increases by 20% then new price will be 120.
So the new price is 120% of the old one.
in another way we can calculate that
old value*x%=new value
⇒old value*x/100=new value
⇒x=new value*100/old value=30*100/25=120%
Therefore the new price is 120% of the old one because the price increases by 20%, which is added to 100%.

What is this percent of change, i'm confused? 1/4 to 1/8
Answer:
Step-by-step explanation:
Percent change= (1/4-1/8)/1/4 × 100%
= {(2 -1)/8} ÷ 1/4 × 100%
= (1/8 ÷ 1/4) × 100%
= 1/8 × 4/1 × 100%

Answer:
x = 29
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
x + 2x + 2 + 3x + 4 = 180, that is
6x + 6 = 180 ( subtract 6 from both sides )
6x = 174 ( divide both sides by 6 )
x = 29

A cone with a radius of 6 cm and a height of 8 cm has the same volume as a cylinder with a height of 6 cm. What is the radius
of the cylinder?
A)4 cm
B)4 cm
C)6 cm
D) 8 cm
Answer:
The radius of the cylinder is 4 cm.
Step-by-step explanation:
Given:
radius of cone = 6 cm
height of the cone = 8 cm
height of cylinder = 6 cm
We need to find the radius of cylinder.
Solution:
First we will find the volume of cone.
Volume of cone is one third time square of radius times height times π.
framing in equation form we get;
Volume of cone = [tex]\frac{1}{3}\pi r^2h = \frac{1}{3}\pi\times 6^2\times 8 \approx 301.44 \ cm^3[/tex]
Now Volume of cylinder is given by square of radius times height times π.
framing in equation form we get;
Volume of cylinder = [tex]\pi r^2h=18.84r^2[/tex]
Now it has been given that;
Volume of cone is equal to Volume of cylinder.
so we can say that
[tex]18.84r^2=301.44[/tex]
Dividing both side by 18.84 we get;
[tex]\frac{18.84r^2}{18.84}=\frac{301.84}{18.84}\\\\r^2\approx16[/tex]
Taking square root on both side we get;
[tex]\sqrt{r^2}=\sqrt{16} \\\\r=4\ cm[/tex]
Hence the radius of the cylinder is 4 cm.

This figure is made up of a rectangle and parallelogram.
What is the area of this figure?
Enter your answer in the box. Do not round any side lengths.
The area of the figure is 40 units. (rounded off from 39.998 units)
Step-by-step explanation:
1. Area of the figure = Area of Rectangle + Area of Parallelogram.
2. Naming points:
Let the rectangle consist of points A(-6,-1), B(-5,-5), C(3,-3) and D(2,1).
Let the parallelogram consist of points C(3,-3), D(2,1), E(2,7) and F(3,3).
3. Each coordinate has a point on the x-axis and a point on the y-axis. We shall refer to these points as x', x'' ,x''' and so on corresponding to the x-axis values of A, B, C and so on in that order till F. For the y-axis points, we will name them in the series of y', y'', y''' and so on.
In simple words, in A(-6,1), x' = -6; y' = -1
4. Formula for finding area:
Area of a rectangle = length (l) × width (w)
Area of a parallelogram = base (b) x height (h)
5. Finding area of the rectangle:
l = AD = [tex]\sqrt{[x'''' - x']^{2} - [y'''' - y']^{2}}[/tex]
, i.e. AD = [tex]\sqrt{[2 - (-6)]^{2} - [1 - (-1)]^{2}}[/tex]
, i.e. AD = √68 = 8.246 (rounded to 3 decimals) = l
Now, w = AB = [tex]\sqrt{[x'' - x']^{2} - [y'' - y']^{2}}[/tex]
, i.e. AB = [tex]\sqrt{[(-5) - (-6)]^{2} - [(-5) - (-1)]^{2}}[/tex]
, i.e. AB = √17 = 4.123 (rounded to 3 decimals) = w
Area of rectangle = l x w = 8.246 x 4.123 = 33.998 units.
6. Finding area of the parallelogram:
b = DE = 6 units (we can observe this from the graph, i.e. points from 1 to 7 on the y axis)
h = Height is the line drawn perpendicular to the base from point F, which as we can see is 1 unit long.
Hence, Area of parallelogram = b x h = 6 x 1 = 6 units.
7. Now, adding both, we can arrive at the final answer.
Area of the figure = Area of rectangle + Area of parallelogram,
i.e. 33.998 units + 6 units = 39.998 units. (can be rounded off to 40 units)
