$\underline{ \underline{ \text{To \: find}}} :$

Cost of 10 note books

$\underline{ \underline{ \text{Solution}}} :$

Finding the cost of 1 note book :

⟼ $\tt{ \frac{252}{12} = Rs 21}$

Finding the cost of 10 note books :

⟼ $\tt{21 \times 10 = Rs 210}$

Answer:

Rs. 210

Step-by-step explanation:

If 12 notebooks (or a dozen) cost 252,

then one notebook will cost 252/12 = 21 rupees.

If one notebook costs 21 rupees, then 10 notebooks will cost 21*10 ruppes, or 210 rupees.

Answer: The area of the sector formed by central angle AOB is 5/8 th of the total area of the circle.

Step-by-step explanation:

Let r be the radius of the circle having the center O,

⇒ The area of the circle = $\pi r^2$ square unit.

And, the central angle AOB = $\frac{5\pi}{4}\text{ radian}$

$=(\frac{5\pi}{4}\times \frac{180}{\pi})^{\circ}$ ( since, $\pi$ = 180° )

$=(\frac{900}{4})^{\circ}$

$=225^{\circ}$

Hence, the area of sector AOB

$=\frac{225^{\circ}}{360^{\circ}}\times \pi r^2$

$=\frac{5}{8}\times \pi r^2$ square unit.

Now,

$\frac{\text{Area of sector AOB}}{\text{Area of circle}}=\frac{\frac{5}{8}\times \pi r^2}{\pi r^2}$

$=\frac{5}{8}$

⇒ Area of sector AOB = 5/8 × Area of the circle.

Hence, the area of the sector formed by central angle AOB is 5/8 th of the total area of the circle.

Answer:

Step-by-step explanation:

$\frac{a}{4}=\frac{b}{7}\\a=\frac{4b}{7} \\\frac{a-b}{b} =\frac{\frac{4b}{7}-b }{b} \\=\frac{4b-7b}{7b}\\ =\frac{-3b}{7b}\\ =\frac{-3}{7}$
