Shelayna has 3 times as many dolls.
3*10=30
Cate has 10.
30-10=20 <=== Shelayna has 20 more dolls than Cate.
I hope this helps!

Answer:
i think you have to count till you get to 4 or 3 then the remaining you plus with the 3
That they are the exact same shape. Some of the sides will be longer and shorter than the other figure, but same shape.
I cannot suggest anything other than the set of real numbers here, but maybe someone else can provide a better answer. As long as you increase or decrease x (which is a real number) then you will get a real number, or the infinite set of real numbers.

Answer:
- 16,965 mm/min
- 90π ≈ 282.7 radians/min
Step-by-step explanation:
The circumference of the CD is ...
C = πd
C = π(120 mm) ≈ 376.99 mm
This is the distance a point on the edge of the CD will travel when making one revolution. It will travel 45 times this far when making 45 revolutions:
(376.99 mm/rev)(45 rev/min) ≈ 16,965 mm/min
__
There are 2π radians in each revolution, so the angular speed is ...
(2π rad/rev)(45 rev/min) = 90π rad/min ≈ 282.7 rad/min
