Answer:
MTTF for the fuses = 62.5
Step-by-step explanation:
Given:
Total fuses = 25
Number of failures = 12
Number of days = 30
Find:
MTTF for the fuses.
Computation:
MTTF for the fuses = Total operation time / Number of failures
MTTF for the fuses = (25 × 30) / 12
MTTF for the fuses = 62.5
Answer:
l=![24\*x^{6}](https://tex.z-dn.net/?f=24%5C%2Ax%5E%7B6%7D)
w=![y^{15}](https://tex.z-dn.net/?f=y%5E%7B15%7D)
Step-by-step explanation:
We know that the area of rectangle can be determined by the multiply the length to the width i.e
A = l • w..................Eq(1)
Here A represented the area .
l= Length of rectangle
w= Width of rectangle
Here A=
...
It can be written as
..............Eq(2)
Comparing the Eq(2) to the Eq(1)
![l=24x^{6}\\ w=y^{15}](https://tex.z-dn.net/?f=l%3D24x%5E%7B6%7D%5C%5C%20w%3Dy%5E%7B15%7D)
Answer:
length = 20
width = 7
Step-by-step explanation:
Perimeter of a rectangle is
P = 2(l+w)
54 = 2( 3x+2 + 2x-5)
Combine like terms
54 = 2( 5x -3)
Divide each side by 2
54/2 = 5x-3
27 = 5x-3
Add 3 to each side
27+3 = 5x-3+3
30 = 5x
Divide by 5
30/5 = 5x/5
6 =x
3x+2 = 3(6)+2 = 18+2 = 20
2x-5 = 2(6)-2 =12-5 =7
