The angle VXU is larger than a 90 degree angle half of an exact straight angle (180 degrees) so it’s obtuse. The only angle larger 90 degree is D :)

The sector COB is cut from the circle with center O. The ratio of the area of the sector removed from the whole circle to the ar

mafiozo [28]

Answer:

$Ratio = \frac{R^2 - r^2 }{ r^2}$

Step-by-step explanation:

Given

See attachment for circles

Required

Ratio of the outer sector to inner sector

The area of a sector is:

$Area = \frac{\theta}{360}\pi r^2$

For the inner circle

$r \to radius$

The sector of the inner circle has the following area

$A_1 = \frac{\theta}{360}\pi r^2$

For the whole circle

$R \to Radius$

The sector of the outer sector has the following area

$A_2 = \frac{\theta}{360}\pi (R^2 - r^2)$

So, the ratio of the outer sector to the inner sector is:

$Ratio = A_2 : A_1$

$Ratio = \frac{\theta}{360}\pi (R^2 - r^2) : \frac{\theta}{360}\pi r^2$

Cancel out common factor

$Ratio = R^2 - r^2 : r^2$

Express as fraction

$Ratio = \frac{R^2 - r^2 }{ r^2}$

jada can write 3 1/4 pages in 8 minutes. At this rate, how many pages could jada write in 24 minutes?

makkiz [27]

Answer:

9 3/4 pages = x

Step-by-step explanation:

$\frac{pages}{minutes} = \frac{pages}{minutes}$ change 3 1/4 to a decimal

$\frac{3.25}{8} = \frac{x}{24}$

$3.25(24) = 8x$

$78 = 8x$

$\frac{78}{8} = x$

$9.75 = x$

$9\frac{3}{4} =x$

working with the fraction

3 1/4 /8 = x/ 24

3 1/4 (24) = 8x

13/4 (24) = 8x

316/4 = 8x

78 = 8x

78/8 = x

9 3/4 = x
