9000 x 0.25 = 2250
9000 - 2250 = 6750
Answer:
=rs. 6750
Step-by-step explanation:
marked price= 9000 = 100%
selling price= ? = 75%
loss= ? = 25%

A parallelogram is dilated by a scale factor of 1/4 to produce a new parallelogram. Which of the following best describes the relationship of the area of the new parallelogram to the area of the original parallelogram?
The area of the new parallelogram is 1/2 the area of the original parallelogram.
The area of the new parallelogram is 1/4 the area of the original parallelogram.
The area of the new parallelogram is 1/16 the area of the original parallelogram.
The area of the new parallelogram is 1/8 the area of the original parallelogram.
Answers
Answer:
C. The area of the new parallelogram is 1/16 the area of the original parallelogram.Step-by-step explanation:
Dilation by a scale factor of 1/4 results in all dimensions reduction 4 times
Since the area is the product of two dimensions, the area of smaller parallelogram is 4*4 = 16 times smaller than the original one.
Correct answer choice is C

Each angle of the equilateral triangle in the figure has measure (2x – 9)°. Determine the value of x.
A) x = 25.5
B) x = 34.5
C) x = 69
D) x = 60
Answers
Answer:
34.5
Step-by-step explanation:
An easy way to find this out is plug in all the answers into our equation until we get 180. So here's what you do:
A) X=25.5
So put that in the equation replacing x like this : 2(25.5)-9 =42 then multiply by three which = 126, So, A) is not our answer, now do it with the rest until you get 180,
2(34.5)-9=60 60x3=180 so your answer will be the number you plug in aka:34.5

URGENT!! WILL MARK BRAILIEST! GOD BLESS. PLEASE SHOW ALL WORK. The age of Vicky and Krishna total 27 years. In 4 years, Krishna’s age plus twice Vickey’s age will be 43. What are Vickey and Krishna’s ages?
Answers
9514 1404 393
Answer:
Vickey is 4Krishna is 23Step-by-step explanation:
Let v represent Vickey's age now. Then Krishna's age now is 27-v. In 4 years, the sum of their ages is ...
(27 -v +4) +2(v +4) = 43
27 -v +4 +2v +8 = 43 . . . . eliminate parentheses
v +39 = 43 . . . . . . . . . . . . . collect terms
v +39 -39 = 43 -39 . . . . . . subtract 39 from both sides
v = 4 . . . . . . . . . . . . . . . . . simplify; this is Vickey's age
27 -v = 23 . . . . . Krishna's age
Vickey's age is 4; Krishna's age is 23.
You are recreating a scale drawing at a different scale. The original scale is 1 cm : 8 m. The new scale is 1 cm : 2 m. In the original drawing, the length of a segment is 9 centimeters. How long should the segment representing the same distance be in the new drawing?
The segment should be ?centimeters long.
Answers
Answer:
The segment should be 36 centimeters long
Step-by-step explanation:
Let us use the ratio method to solve the question
∵ The original scale is 1 cm : 8 m
∵ In the original drawing, the length of a segment is 9 centimeters
→ By using the ratio method
→ cm : m
→ 1 : 8
→ 9 : x
→ By using the cross multiplication
∵ 1 × x = 9 × 8
∴ x = 72 m
∴ The actual length of the segment is 72 m
∵ The new scale is 1 cm : 2 m
∵ The actual length of the segment is 72 m
→ By using the ratio method
→ cm : m
→ 1 : 2
→ y : 72
→ By using the cross multiplication
∵ y × 2 = 1 × 72
∴ 2y = 72
→ Divide both sides by 2 to find y
∴ y = 36
∴ The drawing length of the segment is 36 cm in the new scale
∴ The segment should be 36 centimeters long
Amira is told there is a trick to finding the slope within an equation in standard form, Ax + By= C. She is told she can rewrite this equation in slope-intercept form, y = mx + b, to find the pattern. She correctly rewrites the equation 7x + 9y = 14 in slope-intercept form as y = - 7/9 x + 14/9. Which answer explains the pattern for how to find the slope using an equation in standard form?
Answers
Answer:
The slope of given equation in standard form
[tex]m = \frac{-7}{9}[/tex]
Step-by-step explanation:
Explanation:-
Given equation of the line 7x + 9y = 14
The given equation in slope-intercept form, y = mx + b
Slope - intercept form [tex]y = \frac{-7}{9} x + \frac{14}{9}[/tex]
Comparing m = - 7/9
Here m = -7/9
C = 14/9
The slope of given equation in standard form
[tex]m = \frac{-7}{9}[/tex]

[tex]u_{n} = 2n^{2} -4n-3[/tex]
Step-by-step explanation:
a +b + c = - 5 First term in sequence
3a + b = 2 Difference between first two terms
2a = 4 Difference between the difference of the first two terms and the second third terms (the difference between -5 and -3 is 2 the difference between -3 and 3 is 6; the difference between 6 and two is 4)
2a = 4 so a = 2; 3(2) + b = 2 → 6 + b = 2 so b = -4; 2 - 4 + c = -5 → -2 + c = -5 so c = -3
n is an integer. Prove that (2n+1)(n+3)+(2n+1)(n-2) is not a multiple of 2. thanks.
Answers
Answer:
(2n + 1)(n + 3) + (2n + 1)(n - 2)
= (2n + 1)(n + 3 + n - 2)
= (2n + 1)2n + 1)
= 4n² + 4n + 1
= 2(2n² + 2n) + 1
can see 2(2n² + 2n) is a multiple of 2 but 1 isnt a multiple of 2
=> 2(2n² + 2n) + 1 is not a multiple of 2
=> (2n + 1)(n + 3) + (2n + 1)(n - 2) is not a multiple of 2
