Answer:
m = -3
Step-by-step explanation:
-2m=6
Divide both sides by (-2).
m = 6 ÷ (-2)
m = -3
If I=P*r*t, we can input 450 in for I, 3000 in for the principal (P, or the starting rate), and 3 for t=time because there were three years, resulting in 450=9000*r. Next, we can divide both sides by 9000 to get 0.05 or 5% as our answer.
First, we convert the given radius of the wheel to meters giving us an answre of 0.325 m. Then, we calculate for the circumference.
C = 2πrr
Substituting,
C = 2π(0.325 m) = 2.04 m
Then, we have a road that is 40 m long, the number of complete revolutions is,
n = 40/2.04 m = 20
Answer:
120
Step-by-step explanation:
! means to multiply it by every number less than itself.
Not counting 1, this means 5*4*3*2.
20*3*2
60*2
120
The answer is 120.
