Find the slope between (3,2) and (-2,3)

1 answer:

3 0

$(x_1;\ y_1);\ (x_2;\ y_2)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}\\\\(3;\ 2);\ (-2;\ 3)\\\\\boxed{m=\dfrac{3-2}{-2-3}=\dfrac{1}{-5}=-\dfrac{1}{5}}$

After reading 7/9 of a book, 40 pages are left. Find the total number of pages in the book

dimaraw [331]

Answer:

180 pages

Step-by-step explanation:

let x be the number of pages in the book , then

$\frac{7}{9}$ x + 40 = x ( multiply through by 9 to clear the fraction )

7x + 360 = 9x ( subtract 7x from both sides )

360 = 2x ( divide both sides by 2 )

180 = x

The total number of pages in the book is 180

Answer:

$Angle = 54$

Step-by-step explanation:

Given

Kano = 45;

Kwara = 410;

Ogun = 105;

Ondo = 126;

Oyo = 154

Total Distribution = 840

Required

Determine the angle subtended by Ondo (in a pie chart)

The general formula to calculate subtended angle in a Pie chart is;

$Angle = 360 * \frac{Frequency}{Total\ Frequency}$

In this case of Ondo

Frequency = 126

Total Frequency = Total Distribution = 840

Substitute these values in the given formula;

$Angle = 360 * \frac{126}{840}$

$Angle = \frac{360 *126}{840}$

$Angle = \frac{45360}{840}$

$Angle = 54$

Hence, the angle subtended by Ondo is 54
