5/14 is the answer
Good luck on the test lol-
Answer:
I have the pictures of the whole answer book if you want to see them add me on disco
Step-by-step explanation:
3(100-b) = 6b
300-3b = 6b
+3b +3b
300 = 9b
/9 /9
b=33.33333... or 33 1/3
Hope this helps!
7.5cm
lets take point K represent lenght from M to perimeter of circle.
r is radius
KM= r-OM= r-4.5cm
now lets draw line from O to A (OA)
we get triangle.
hypotenuse is OA and it equals r(radius)
ab=12 cm. so another side of the triangle (AM) is 12/2=6cm. and the last side of the triangle is 4.5(OM)
use pythaghorean theorem
squares of sides added = square of hypotenuse
20.25+36=r^2(our hypotenuse is radius)
56.25=r^2
r=√56.25=7.5cm
