80% own a cell phone, so 20 % do not own a cell phone.
45% own a pager, so 55% do not own a pager.
20% + 55% = 75% don't own either.
The answer is E. 75%

Step-by-step explanation:
The volume of the larger ball bearing is 8 times the volume of the
smaller one
Step-by-step explanation:
All the spheres are similar, and there is a ratio between their radii
So the ratio between their:
1. Diameters⇒ =
2. Areas ⇒ =
3. Volumes ⇒ =
∵ The radius of the larger ball bearing is twice the radius of the
smaller one
- That means the radius of the larger sphere is equal to the radius
of the smaller sphere multiplied by 2
∴ =
∵ =
∴ =
∴ =
<em>The volume of the larger ball bearing is 8 times the volume of the </em>
<em>smaller one</em>

Answer:
Step-by-step explanation:
Since it is an equilaterla triangle, we can see the side opposite to that of side length 4 is 60 degrees. Since the other angle is a right angle (90 degrees), we can find that the other side is 30 degrees (the degrees add up to 180). We can also see that this is a 30-60-90. We can see that the side x, through the identity (you can find 30-60-90 identity online), we see that the side x is . However, it is also asking us to simplify this, so we multiply the top and bottom by and get
