Answer:
B
Step-by-step explanation:
We can start by converting 1 into 6/6 and 1/3 into 2/6. This makes subtraction much easier, and by subtracting the numerators, (6/6 - 2/6) you should get 4/6.
Make sure you know the formula pertaining to the question.
1. c=2(pi)(r)
2. c=2(pi)(d)
r= radius
d= diameter
c= sircumference
So we are given that the circumference of a circle is 12.3pi and the radius is unknown.
So let's plug in the known values
**we use the formula with the radius, becuase we are looking for the radius.
c=2(pi)(r)
12.3(pi)=2(pi)(r)
divide each side by pi
12.3=2(r)
divide each side by 2
r=6.15 in.
Answer:
4,969.25
Step-by-step explanation:
$19877 ÷ 4
you van either divide this the long way or the short way either one will give you the same answer so just try it out and see
2x^2-15=x
2x^2-x-15=0
(X-3)(2x-5)=0
x-3=0 or 2x-5=0
X=3 2x=5
x=5/2=2.5
Answer:
triangular prism
0.5 X 5 X 4 X 9 = 90 cubed cm
cuboid
6 X 5 X 20 = 600 cubed cm
triangular prism : cuboid
90:600
now simplify
both are divisible by 30
3:20
this cannot be simplified further
answer = 3:20
