Answer:

P ( not white ball) = 2/3

Step-by-step explanation:

If there are 10 blue balls and 10 black balls and 10 white balls,

10+10+10 = 30 total balls

P(white ball) = white balls/ total balls

= 10/30

= 1/3

P (not getting a white ball) = not white/ total

= (blue + black)/ total

= (10+10)/30

=20/30

2/3

How do you find the area of the shaded sector of the circle? The radius is 10in and the sector is 45 degrees

Step2247 [10]

Given:

Radius of the circle = 10 in

Central angle of the sector = 45 degrees

To find:

The area of the sector.

Solution:

Area of a sector is

$A=\dfrac{\theta}{360^\circ}\pi r^2$

Where, $\theta$ is the central angle in degrees.

Putting r=10 and $\theta=45^\circ$ , we get

$A=\dfrac{45^\circ}{360^\circ}\pi (10)^2$

$A=\dfrac{1}{8}\pi (100)$

$A=12.5\pi$

Therefore, the area of the sector is 12.5π sq. inches.

Write an expression for the calculation 4 added to 12 times 19 plus 24

harina [27]

Answer:

4 + 12 × 19 + 24

Step-by-step explanation:

Hullo!

Words like "added or sum", represent addition.

Words like "times", represent multiplication.

Words like "subtracted or took away", represent subtraction.

Words like "divided or split up", represent division.

Therefore, we can express the equation 4 added to 12 times 19 plus 24 can be rewritten as $\boxed{4 + 12 \cdot 19 + 24}$ in expression format.

Hope this helps!
