Answer:
65.9734457254 or 65.97
Step-by-step explanation:
c= pi x diameter
c= pi x (10.5 x 2)
c= pi x 21
= 65.9734457254
Answer:
the slope of A'B' = 3
A'B' passes through point O
Step-by-step explanation:
A dilation with scale factor 3 gives the effect of stretching the line AB three times longer. As dilation does not change the direction of the line, the slope will stay the same. If point O lies on AB and is the center of dilation, then the point O must also lie on A'B'
Answer:
x < 4
Step-by-step explanation:
Step 1: Write inequality
5x < 20
Step 2: Solve for <em>x</em>
- Divide both sides by 5: x < 4
Here we see that any number less than 4 will work. So numbers like 3, 0, or even -12587235897 would work.
Answer:
v = 3
Step-by-step explanation:
You can start by distributing -2:
-2v - 2 = 3v -17
Next, add 2v to both sides to combine the v terms:
-2v - 2 = 3v - 17
+2v +2v
-2 = 5v - 17
To isolate the v term, we add 17 to both sides:
-2 = 5v - 17
+17 +17
15 = 5v
Lastly, divide by 5 to get v:
15 = 5v
÷ 5 ÷5
3 = v --> v = 3
