Mathematics
1 answer:

Answer: The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle.

The formula for calculating the radius is different from calculating the diameter

Find radius

r= diameter/ 2

Radius is half of a diameter

While diameter is

d=2r

Whats the slope of the line? (Multi choice)<br> 1. 1/2<br> 2. -1/2<br> 3. 2<br> 4. -2
otez555 [7]

Answer:

1. 1/2

Step-by-step explanation:

     With a graph that has easily see-able points, slope can be calculated with rise over run, or change in y divided by change in x

\frac{2-1}{2-0} =\frac{1}{2}

      What does the \frac{1}{2} mean? From any point, the next point will be up one and over to the right two. Since the graph is going from bottom left to top right, it is positive.

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

B/13-3b/13=8/13 help please
OLEGan [10]
\frac{b}{13} - \frac{3b}{13} = \frac{8}{13}
Since the two fractions have a common denominator already, we can just subtract the numerators.
b-3b=-2b or -3b+b=-2b
Either way you get the same answer :)
Our new fraction is \frac{-2b}{13}
Now we know that this must be equal to \frac{8}{13}
Again, since the denominators are already the same of course they are equal. 13=13
Now we have to set the numerators equal
-2b=8
Use inverse operations to get b alone
-2b=8
÷-2   ÷-2
b=-4
If you have any questions, feel free to ask. Hope this helped! :)

Determine whether the polygons are similar. If so, identify the correct similarity ratio and the similarity statement. HELP ASAP
Vilka [71]

Answer:

  No, the triangles are not similar

Step-by-step explanation:

The (reduced) side length ratios, shortest to longest, are ...

  12 : 18 : 20 = 6 : 9 : 10

and

  5 : 12 : 13

These are not the same, so the triangles are not similar.
