Answer:
Step-by-step explanation:
sin(x°) = 4/5
x° = arcsin(4/5) ≅ 53.1°
2 1/2x - 3/4(2x+5)=3/8 3/8=0.375
2.5x - 0.75(2x+5)=0.375
2.5x - 1.5x - 3.75 = 0.373
2.5x-1.5x=4.12
1x=4.12
X= 4 1/8
The answer is: [D]: 11 1/2 .

2 7/8 <span>÷ 1/4 =
23/8 </span>÷ 1/4 = 23/8 * 4/1 ; The "4" cancels to a "1"; and the "8"
cancels to a "2"; (since "8÷4 =2" ;
and "4÷4 = 1" ;
__________________________________________________________
→ 23/8 * 4/1 = 23/2 * 1/1 = 23/2 * 1 = 23/2 = 11 1/2 ;

→ which is: Answer choice: [D].

Answer:
96 in^2.
Step-by-step explanation:
It has 6 surfaces each of area 4*4 = 16
Answer is 6*16 = 96.
Answer:
The system will be inconsistent.
Step-by-step explanation:
We are given that a system of linear equations has a 3×5 augmented matrix whose fifth column is a pivot column.
Then such a system is not consistent because since the augmented matrix has a pivot in fifth column it means that the new column added to the matrix A will lead to increase in the rank as that of matrix A.
Hence the rank of A and Augment A will not remain same and hence the system will be inconsistent.
