Answer:
5/12
Step-by-step explanation:
Total distance travelled = 30% + 1/4
To add these numbers, convert 30% to fraction
30% = 1/3
1/3 + 1/4 = 7/12
Remaining distance = 1 - 7/12 = 5/12
Answer:

------------- = 2.5 mi/min
5 min
Answer:
Option D i.e. y = 1/2 x is the correct answer.
Step-by-step explanation:
We know that when 'y' varies directly with 'x', we get the equation
y ∝ x
y = kx
where k is the constant of proportionality.
In our case, the only equation which maps in accordance with y = kx is y = 1/2x.
i.e.
y = 1/2 x
here k = 1/2
Thus, k = 1/2 is the constant of proportionality.
Therefore, option D i.e. y = 1/2 x is the correct answer.
Answer:
1470
Step-by-step explanation:
30 + 40 = 70
70 x 21 = 1470
We are given a polynomial function has :
A root of –3 (multiplicity 2).
Therefore, one factor would be (x+3)^2
A root of 0 with multiplicity 1.
Therefore another factor is x.
A root of 1 with multiplicity 1.
Therefore another factor is (x-1).
A root of 3 with multiplicity 2.
Therefore, another factor would be (x-3)^2
Therefore, polynomial function would
