Answer:
2.5 hours
Step-by-step explanation:
Basically you can see there is 2 hours. Then since there is half an hour left, it will be .5 hours.
So you now have 2.5 hours.
30/-6 equals 5. You’re welcome
Answer with explanation:
For, a Matrix A , having eigenvector 'v' has eigenvalue =2
The order of matrix is not given.
It has one eigenvalue it means it is of order , 1×1.
→A=[a]
Determinant [a-k I]=0, where k is eigenvalue of the given matrix.
It is given that,
k=2
For, k=2, the matrix [a-2 I] will become singular,that is
→ Determinant |a-2 I|=0
→I=[1]
→a=2
Let , v be the corresponding eigenvector of the given eigenvalue.
→[a-I] v=0
→[2-1] v=[0]
→[v]=[0]
→v=0
Now, corresponding eigenvector(v), when eigenvalue is 2 =0
We have to find solution of the system
→Ax=v
→[2] x=0
→[2 x] =[0]
→x=0, is one solution of the system.
Answer:
2/3 : 3/2 = 4 : 9
Step-by-step explanation:
LCD(2/3, 3/2) = 6
2/3 : 3/2 = 4/6 : 9/6
Our two fractions now have like denominators so we can multiply both by 6 to eliminate the denominators.
2/3 : 3/2 = 4 : 9
The GCF of 4 and 9 is 1
Divide both terms by the GCF, 1:
4 ÷ 1 = 4
9 ÷ 1 = 9
The ratio 4 : 9 cannot be reduced further by dividing both terms by the GCF = 1 :
Therefore:
2/3 : 3/2 = 4 : 9
