Answer:
3/10
Step-by-step explanation:
The central angle of the arc is .
The circumference of an arc of a circle is given as:
where C= circumference of the circle
θ = central angle of the arc
Therefore, the circumference of the arc is:
The circumference of the arc will be 3/10 of the circumference of the circle.

Answer:
2 2/3
Step-by-step explanation:
Let the number be represented by x. Then the problem statement is telling you ...
4 5/9 = 2 1/3 + (5/6)x
You can isolate the x term by subtracting 2 1/3 from both sides of the equation. (The properties of equality require that the same operation be performed on both sides of the equation.)
(4 5/9) - (2 3/9) = (2 3/9) -(2 3/9) +(5/6)x
2 2/9 = (5/6)x
The definition of the multiplicative inverse tells you that the coefficient of x can be made to be 1 if the term is multiplied by (6/5). We must do that to both sides of the equation.
(6/5)(2 2/9) = (6/5)(5/6)x
(6/5)(20/9) = x . . . . simplify
120/45 = x . . . . . . do the multiplication
8/3 = x = 2 2/3 . . . . . . . reduce the fraction
The number is 2 2/3.

<em>Additional comment</em>
The number we're looking for is multiplied by 5/6 and the result has 2 1/3 added to it. To find the number, we "undo" these operations, in reverse order. We undo the addition by subtracting the amount that was added. We undo the multiplication by multiplying by the inverse of that factor.
This is the sort of logic that you would use to fill in the blank for ...
7 = 1 + 3×___
You probably recognize that this breaks down into two problems:
7 = 1 + ___ . . . . . (6 goes in the blank)
and
6 = 3×___
You may notice that for all of these problems, a good knowledge of addition and multiplication facts is useful.
Answer: All you have to do is divide 39 and 3 and you get 13. That is how many in a row.
Step-by-step explanation:
I hope that is right if not sorry.
we have
we know that
The volume of a cube is equal to
where
b is the length side of a cube
Using a graph tool------> find the roots of the polynomial
see the attached figure
x=4
so
therefore
<u>The answer is</u>
the length side of a cube is equal to (x-4)
I believe you're asking what is 1/3rd of 96 which is found by dividing 96 by 3 to get 32
