-40 +2n= 4n -8(n+8)
-40 +2n= 4n -8n -64
-40 + 2n = -4n -64
2n = -4n -64 +40
2n=-4n-24
2n+4n=-24
8n=-24
N= -3
Answer is n equals -3
Answer:
65.312 inches
326.56 inches
1959.36 inches
Step-by-step explanation:
Given
d = 20.8 inches
To find
Travel in 1, 5, 30 rotations
Solution
Circumference of the wheel is equal to one full rotation
C = πd = 3.14*20.8 = 65.312 inches
5C = 5*65.312 = 326.56 inches
30C = 30*65.312 = 1959.36 inches
Step-by-step explanation:
Answer:
49
Step-by-step explanation:
Positive 49 not -49
To work out the Circumference of a circle, we must o the calculation
πd
π x d
If we fill in the information we know
π x 10.4
3.14 x 10.4 (to 2 d.p.)
↓
32.656 (units)
<u>Answer: x-axis</u>
<u><em>Explanation</em></u>:
- x-axis: it is the horizonzontal axis
- x-coordinates: it is the x-value of a point in reference to the x-axis
- y-axis: it is the vertical axis
- y-coordinates: it is the y-value of a point in reference to the y-axis
Hope that helps!
