Answer:
A fraction that would be equivalent to 3/6 would be 1/2, therefore a shaded circle would be half of a circle.
Answer:
c.132
Step-by-step explanation:
so we are given the diameter which is 42m **the diameter is the straight line that passes through the middle of the circle**
but in order to find the circumference we need to find the radius **the radius is always half (1/2,0.5) of the diameter**
so we have to divide 42/2 which equals 21
now we need to set up the formula;
c=2πr/c=2xπxr **when unknown variables such as 'r' are next to another mathematical numeral such as the pi symbol you don't really have to but the multiplication symbol between them**
c=2π21
=131.946891451
and in your case, it seems we must round to the tenths place so the nine then "becomes a ten" and you're left with 132
good luck :)
i hope this helps
have a good one !!
1. False because a rational is a fraction or part of a number (

).

2. True; a real number is any number that isn't imaginary (

)
3. True; same reason
4. True; an integer is any number that can be wrote without a fraction or decimal (the opposite of rational).
5. True;

and that's a decimal.
6. True; the natural number system starts from 0 and counts upwards
7. True; reason above
Hello,
Let's factor:
2(4x-1)² * (x+5) + 6(4x-1)³ * (x+5)
=2(4x-1)²(x+5)*[1+3(4x-1)]
=2(4x-1)²(x+5)(12x-2)
=4(4x-1)²(x+5)(6x-1)
