Answer:
[tex] \boxed{ \huge{ \bold{ \sf{\boxed{ \: Rs \: 25425}}}}}[/tex]Step-by-step explanation:
Given,
Marked Price ( MP ) = Rs 25000
Vat percent = 13 %
Discount percent = 10 %
▪️Finding the discount amount
Discount amount = Discount % of MP
= 10 % of 25000
= Rs 2500
▪️Finding the Selling price
Selling price ( SP ) = MP - Discount amount
= Rs 25000 - Rs 2500
= Rs 22500
▪️Finding the Vat amount
Vat amount = Vat % of SP
= 13 % of 22500
= Rs 2925
▪️Finding the SP with VAT
SP with vat = SP + Vat amount
= Rs 22500 + Rs 2925
= Rs 25425

1).[tex] \frac{x}{8} = \frac{9}{24} [/tex]
Cross multiply
We have
24x = 72
Divide both sides by 24
That's
[tex] \frac{24x}{24} = \frac{72}{24} [/tex]
We have the answer as
x = 32).3x² + 2x - 10
when x = - 1
Substitute the value of x into the expression
That's
3(-1)² + 2(-1) - 10
= 3 - 2 - 10
We have the answer as
- 9When x = 0
That's
3(0) + 2(0) - 10
= - 10When x = 1
That's
3(1)² + 2(1) - 10
= 3 + 2 - 10
= 5 - 10
= - 53).[tex] \sqrt{( - 9)} [/tex]
First of all apply the radical rule
That's
[tex] \sqrt{ - a} = \sqrt{ - 1} \times \sqrt{a} [/tex]
So we have
[tex] \sqrt{ - 9} = \sqrt{ - 1} \times \sqrt{9} [/tex]
Using the imaginary rule
That's
[tex] \sqrt{ - 1} = i[/tex]
We have
[tex] \sqrt{9} \times i[/tex]
We have the final answer as
3i 4).[tex] \frac{1}{x} [/tex]
when x = 0
We have
[tex] \frac{1}{0} = 0[/tex]
when x = 1
[tex] \frac{1}{1} = 1[/tex]
when x = 2
We have
[tex] \frac{1}{2} [/tex]

9x + 1 - 7x - 5 = -20
Answer:
-8
Step-by-step explanation:
First add together the x's.
2x + 1 - 5 = -20
Now add 1 and -5,
2x - 4 = -20
Add 4 to both sides,
2x - 4 + 4 = -20 + 4
2x = -16
Divide both sides by 2,
2x/2 = -16/2
x = -8
hey guys.... please help me with this question ,chapter lines and angles and i will mark u the brainiest if u answer it 1st (6 marks)
Answer:
Step-by-step explanation:
Alternate angles:When two lines are crossed by another line the pair of angles on opposite sides of the transversal is called alternate angles.
Theorem 1:If a transversal intersects two Parallel Lines then each pair of alternate interior angles is equal.
Theorem 2 :If a transversal intersects two lines such that a pair alternate interior angle is equal then the two lines are parallel.
SOLUTION:
Given: ∠AGE=126°
∠AGE=∠GED=126∘ [alternate interior angles]
(ii) ∠GED=∠GEF+∠FED=126∘
∠GEF + 90° =126°
(GIVEN that EF⊥CD)
∠GEF=126°−90°=36°
∠GEF=36°
(iii) ∠CEG+∠GED=180°
(GIVEN ∠GED=126∘)
∠CEG+126° =180°
∠CEG=180° −126°
∠CEG=54°
∠FGE=∠CEG= 54° (alternate angles)

The perimeter of the polygon shown in the figure is _______. Question 9 options: 204 units 2√34 +6 units 15 units 30 units
Answer:
[tex] 2\sqrt{34} + 6 units [/tex]
Step-by-step explanation:
The perimeter of the polygon shown = AC + BC + AB
Using distance formula, calculate the distance formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex], calculate AC, BC, and AB.
The coordinates of the points are as follows,
A(3, 5),
B(0, 0)
C(6, 0)
Find AB:
[tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Where,
A(3, 5) => (x1, y1)
B(0, 0) => (x2, y2)
[tex] AB = \sqrt{(0 - 3)^2 + (0 - 5)^2} [/tex]
[tex] AB = \sqrt{(-3)^2 + (-5)^2} = \sqrt{9 + 25} = \sqrt{34} [/tex]
[tex] AB = \sqrt{34} units [/tex]
Find BC:
BC is easy to determine from the graph directly. The distance from point B to C, is 6 units.
Find AC:
[tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Where,
A(3, 5) => (x1, y1)
C(6, 0) => (x2, y2)
[tex] AC = \sqrt{(6 - 3)^2 + (0 - 5)^2} [/tex]
[tex] AB = \sqrt{(3)^2 + (-5)^2} = \sqrt{9 + 25} = \sqrt{34} [/tex]
[tex] AC = \sqrt{34} units [/tex]
Perimeter of the polygon = [tex] \sqrt{34} + 6 + \sqrt{34} [/tex]
[tex] = (\sqrt{34} + \sqrt{34}) + 6 [/tex]
[tex] = 2\sqrt{34} + 6 [/tex]
Answer:
2√34 +6 units

Margo uses dots to track her activities on a calendar. Red dots represent homework, yellow dots represent work, and green dots represent practice. In a typical week she uses 5 red dots, 3 yellow dots, and 4 green dots. How many activities does Margo do in 4 weeks?
Answer: Margo does 48 activities in 4 weeks.
Step-by-step explanation:
In the calendar,
Red dots represent homework, yellow dots represent work, and green dots represent practice.
On a typical week , she uses 5 red dots, 3 yellow dots, and 4 green dots.
That means , total activity he does in a week = 5+3+4=12
Then, total activities in 4 weeks = 4 x 12 = 48
Hence, Margo does 48 activities in 4 weeks.

HELP S.O.S HELPPPPPP ME Agranola bite contains 27 calories. Most of the calories come from grams of carbohydrates. The rest come from other
ingredients. One gram of carbohydrate contains 4 calories.
The equation 4c + 5 = 27 represents the relationship between these quantities.
1. What could the 5 represent in this situation?
2. Priya said that neither 8 nor 3 could be the solution to the equation. Explain why she is correct.
3 Find the solution to the equation,
Answer:
see below
Step-by-step explanation:
4c + 5 = 27
1. 5 is the calories that come from something else besides carbohydrates in the one bite.
2.
Test the values 8 and 3
4*8 +5 = 32+5 = 37 this does not equal 27
4*3+5 = 12+5 = 17 this does not equal 27
neither 8 nor 3 are solutions
3.
4c + 5 = 27
Subtract 5 from each side
4c + 5-5 = 27-5
4c = 22
Divide each side by 4
4c/4 = 22/4
c =5.5
Answer:
A. The 5 would stand for the other ingredients.
B. She is correct since if you plug in those numbers for c they would be wrong
C. 5.5
Step-by-step explanation:
A. The 5 would stand for the other ingredients.
The reason that it is the other ingredients since it is the only other possible answer
B. She is correct since if you plug in those numbers for c they would be wrong
C. 5.5
To do this you would just subtract 5 from both sides leaving you with 4c=22 then you would divide 4 from both sides so you get c= 22/4 and when you simplify you get 11/2 which as a number is 5.5

The variable Weight (lb. or kg) is measured on a ___________ scale of measurement Interval Ratio Nominal Ordinal.
Answer:
Interval Ratio
Step-by-step explanation:
In statistics, the level of measurement used for a variable determines the what summary statistics and analysis are possible. There are three types of level of measurement.
Nominal
Ordinal
Interval/ Ratio
The nominal is the most basic level of measurement. It is known as categorical or qualitative. Examples includes, numbers,color, sex. Nominal can be stored as a word or text or given a numerical code.However, the number do not imply order. They are usually expressed in percentage
Ordinal are variables based on ranks, they are usually have a meaningful order but the intervals between the variables may not be equal. They are usually expressed in frequencies.
The interval/ratio level of measurement is the most precise level of measurement. Data can be measured and ordered. Examples include, number of customers, age, weight or size. Interval / Ratio data is also known as scale, parametric or quantitative. Interval / Ratio can be discrete with whole numbers or continuous with fractional numbers.

The base of a triangle measures 6 inches less than its height. If the area of the triangle is 20 square inches, find the base and height using the formula A= 1/2bh
Answer:
height = 10 inches
base = 6 inches
The height and base width of the triangle will be 4 inches and 10 inches, respectively.
What is the area of the triangle?Assume 'h' is the height of the triangle and 'b' be the base of the triangle. Then the area of the triangle is given as,
A = (1/2) × h·b
The base of a triangle measures 6 inches less than its height. If the area of the triangle is 20 square inches. Then the equations are given as,
b = h - 6 ...1
20 = (1/2)bh
40 = bh ...2
From equations 1 and 2, then we have
40 = (h - 6)h
40 = h² - 6h
h² - 6h - 40 = 0
h² - 10h + 4h - 40 = 0
h(h - 10) + 4(h - 10) = 0
(h - 10)(h + 4) = 0
h = 10, -4
The height can be negative, so neglect -4. Then the width of the triangle is given as,
b = 10 - 6
h = 4
The height and base width of the triangle will be 4 inches and 10 inches, respectively.
More about the area of the triangle link is given below.

Use the figure to write the segment addition postulate, write and equation and solve for x.
Pls explain
Answer:
[tex] x = 3 [/tex]
Step-by-step explanation:
From the figure given, we have points A,B, and C, that are collinear. Therefore, according to the segment addition postulate, [tex] AB + BC = AC [/tex].
We are given that:
AB = 9x + 7
BC = -5x + 20
AC = 39
An equation that can be used to solve for x would be:
[tex] (9x + 7) + (-5x + 20) = 39 [/tex]
Solve for x
[tex] 9x + 7 - 5x + 20 = 39 [/tex]
[tex] 9x - 5x + 7 + 20 = 39 [/tex]
[tex] 4x + 27 = 39 [/tex]
Subtract 27 from both sides
[tex] 4x + 27 -27 = 39 - 27 [/tex]
[tex] 4x = 12 [/tex]
Divide both sides by 4
[tex] \frac{4x}{4} = \frac{12}{4} [/tex]
[tex] x = 3 [/tex]

EXAMPLE 11 Show that the points (1,-1),(5,2) and (9,5) are collinear
Answer:
see explanation
Step-by-step explanation:
They are collinear if the have the same slope
(2 - -1)/(5 - 1) = 3/4
(5 - 2)/(9 - 5) = 3/4
(5 - -1)/(9 - 1) = 6/8 = 3/4
Step-by-step explanation:
Hey, there!!!
Your question is about showing the points A(1,-1), B(5,2) and C(9,5) as a collinear point.
We generally slope to find weather the points are collinear or not.
So, let's find slope for AB.
[tex]slope(m) = \frac{y2 - y1}{x2 - x1} [/tex]
[tex] slope = \frac{2 + 1}{5 - 1} [/tex]
Therefore, slope of AB = 3/4.
Now, slope of BC.
[tex]slope(m) = \frac{y2 - y1}{x2 - x1} [/tex]
[tex]slope \: (m) = \frac{5 - 2}{9 - 5} [/tex]
Therefore, the slope is 3/4.
now, lastly slope of AC.
[tex]slope(m) = \frac{y2 - y1}{x2 - x1} [/tex]
[tex]slope(m) = \frac{5 + 1}{9 - 1} [/tex]
Therefore, the slope of AC is 3/4.
As all point have same slope. They are collinear point.

It is claimed that an automobile is driven on the average more than 20,000 kilometers per year. To this claim, a random sample of 20 automobile owners is asked to keep a record of the kilometers they travel. Would you agree with the claim if the random sample showed an average of 23,500 kilometers and standard deviation of 3900 kilometers? Use alpha = 5%.
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Sample mean(x) = 23500
Sample standard deviation (sd) = 3900
Sample size (n) = 20
Population mean (m) = 20,000
Null hypothesis : m = 20000
H1: m > 20000
To obtain the z-score :
(population mean - sample mean) / (sample standard deviation /√sample size)
(x - m) / (sd/√n)
(23500 - 20000) / (3900 / √20)
3500 / (3900 /4.4721359)
3500 / 872.06651
= 4.0134
Get the P value to know if to reject or accept the null:
P(z > 4.0134) = 1 - P(z < 4.0134)
P(z < 4.0134) = 1
1 - P(z < 4.0134) = 1 - 1 =0
Since P value is < alpha, we reject the null.
Hence average is > 20000
