Yes you are correct, GCF of both terms is x, so you can factor x out.
3x - x² ⇒ x(3 - x)
This is a division problem.
Divide 349.65 by 7
This is 49.95
Answer is $49.95
To check multiply 49.95 x 7= 349.65
Answer:
see below
Step-by-step explanation:
yes it matters, if you don't know how to write a repeating decimal as a fraction you can use this trick
let's say we don't know what it is
0.33333333...
so we see that there's only one repeating digit
so the answer is
(the repeating digit)/(9)=3/9
and that simplyfies to 1/3
let's try another one
0.67676767...
as you can see know the repeating is 67
so the answer is
(the thing that repeats)/(99)=67/99
do you see a pattern?
when we have a number x of repeating decimals
the denominator of the fraction (the thing that's down) is 9999..99 in there must be x 9's
let me explain
if you have 3 repeating decimals
the denominator will be 999
you see 3 nines
and so on.
Answer:
4.4mm
Step-by-step explanation:
Circumference of circle
2 Pi r
Diameter of coin = 22mm
Therefore the radius = 11mm
Therfroe the outer edge (circumference)
= 2 Pi r
= 2 x Pi x 11
=69.11mm
For the inner edge
Diameter = 5
Radius = 2.5
Therefroe inner edge (circumference)
= 2 Pi r
= 2 x Pi x 2.5
= 15.7mm
The difference is
69.11 - 15.7
=4.4mm
236.5% is the correct answer
