Answer:
Step-by-step explanation:
Second term = -12; d = 5
First term = -12 - 5 = -17
nth term = a + (n-1)*d
= -17 + (n-1)*5
= -17 + 5n - 5
= -22 + 5n
Answer:
radius = C / 2π :)
Step-by-step explanation:
The circumference is 2πr, right?
Let's put this information into an equation :)
C = 2πr
Now, we can simply divide both sides by 2π here to isolate r (the radius) by itself, because that's what we want! (Something equal to the radius)
C / 2π = r
There's your answer! :)
Answer:
0.35
Step-by-step explanation:
0.25 × 1.4 =
0.25×100=25
1.4 × 10 = 14
25×10=250
25×4=100
250+100=350
25×14=350
350÷1000(0.25》25, 1.4》14)
0.35
