Answer: See explanation
Step-by-step explanation:
Your question isn't complete but I'm assuming that you want to calculate the radius.
Circumference of a circle = 2πr
where Circumference = 18.9 meters
Radius = Unknown
π = 3.14
We then put the values into the formula which will be:
C = 2πr
18.9 = 2 × 3.14 × r
18.9 = 6.28r
r = 18.9 / 6.28
r = 3
The radius = 3 meters
Assuming you probably want to get the diameter, we multiply the radius by 2. This will be:
= 2 × 3
= 6 meters
Answer:
Step-by-step explanation:

Solve using distributive property
can be rewritten as 
So:
Factorize:
Now, we can apply distributive property on the expression;
Hence, the above is an equivalent expression.
Solving further, we have
-2 , -3, 6, -1, -9, 5, 3, -5, 4, -6
add them up = -8
1) f(x)=7x-8 and g(x) = 4-x: find f(g(x))
f(g(x)) = [7(4-x) -8] = -7x+20
Domaine of f(x)/g(x) = (7x-8)/(4-x)
this function is valid for all x≠4
<u />domaine = ]- ∞,4[ ∪ ]4, + ∞[<u />
Answer:
60:150
Step-by-step explanation:
So first you can divide 210 by 7 since it will be spilt into seven parts.
210/7 = 30
So in order to get them into the ratios:
30 x 2 = 60
30 x 5 = 150
So 210 in the ratio of 2:5 would be 60:150
You can check your work by adding 60 + 150 together.
