A shopkeeper purchased 100 blankets at Rs. 2000 each. He found that 10 blankets were
defective and he sold these at Rs. 1200 each. At what rate should he sell the remaining
blankets so as to gain 14% on the whole ?​

Answers

Answer:

2,400.

Step-by-step explanation:

Since the shopkeeper bought 100 blankets at $ 2000 each, he spent a total of $ 200,000. He wants to make a total profit of 14% through his sale, that is, he wants to make sales for $ 228,000 (200,000 x 1.14).

Since he sold 10 defective blankets at $ 1200 each, he recovered a total of $ 12,000. Therefore, he has $ 216,000 (228,000 - 12,000) left to achieve his goal, through the sale of 90 blankets. Therefore, you must sell each blanket for $ 2,400 (216,000 / 90) to make the desired profit.

What is the midpoint of the segment shown below? ​

Answers

Answer:

We conclude that the midpoint of the segment is:

[tex]\left(-\frac{9}{2},\:\frac{3}{2}\right)[/tex]

Hence, option D is correct.

Step-by-step explanation:

Given the points

(-6, -1)(-3, 4)

Finding the midpoint of the segment using the formula

[tex]\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-3,\:4\right),\:\left(x_2,\:y_2\right)=\left(-6,\:-1\right)[/tex]

so

[tex]=\left(\frac{-6-3}{2},\:\frac{-1+4}{2}\right)[/tex]

[tex]=\left(-\frac{9}{2},\:\frac{3}{2}\right)[/tex]

Therefore, we conclude that the midpoint of the segment is:

[tex]\left(-\frac{9}{2},\:\frac{3}{2}\right)[/tex]

Hence, option D is correct.

Step-by-step explanation:

2x-5y=9
3x+4y=2
Simultaneous equation find x and y

Answers

Answer:

x = 2

y = -1

Step-by-step explanation:

2x - 5y = 9

3x + 4y = 2

find x in terms of y using the first equation

2x - 5y = 9

2x = 9 + 5y

x = 4.5 + 2.5y

substitute x for 4.5 + 2.5y in the second equation

3x + 4y = 2

3(4.5 + 2.5y) + 4y = 2

13.5 + 7.5y + 4y = 2

13.5 + 11.5y = 2

11.5y = 2 - 13.5

11.5y = -11.5

y = -1

now substitute y for -1 in the first equation

2x - 5y = 9

2x + 5 = 9

2x = 9 - 5

2x = 4

x = 2

This table models a linear function.

x -8 -4 4 8
y -1 0 2 3

Enter the coordinates of the y-intercept in the boxes.

Answers

Answer:

[tex](x,y) = (0,1)[/tex]

Step-by-step explanation:

Given

The above table

Required

Determine the coordinates of the y intercept

Represent points on the table as:

[tex](x_1,y_1) = (4,2)[/tex]

[tex](x_2,y_2) = (8,3)[/tex]

First, calculate slope (m):

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{3-2}{8 - 4}[/tex]

[tex]m = \frac{1}{4}[/tex]

For y intercept, the following coordinate point exist:

[tex](x_3,y_3) = (0,y)[/tex]

Because x = 0 at y intercept

Calculate the slope as:

[tex]m = \frac{y_3 - y_1}{x_3 - x_1}[/tex]

The equation becomes

[tex]\frac{1}{4} = \frac{y - 2}{0 - 4}[/tex]

[tex]\frac{1}{4} = \frac{y - 2}{- 4}[/tex]

Cross Multiply:

[tex]4(y-2) = -4 * 1[/tex]

Divide through by 4

[tex]y - 2 = -1 * 1[/tex]

[tex]y - 2 = -1[/tex]

Make y the subject:

[tex]y = 2-1[/tex]

[tex]y = 1[/tex]

Hence, the coordinates of the y intercept is:

[tex](x,y) = (0,1)[/tex]

219 Seconds

He was 1 second faster because:
