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
The values of x in the rectangles will be:
a. x = -3
b. x = 1
<h3>How to calculate the value?</h3>
It should be noted that the variables given in the rectangle will be equated. This will be:
3x + 18 = 24 + 5x
Collect like terms
5x - 3x = 18 - 24
2x = -6
x = -6/2 = -3
b. The value of x will be:
-4 + 9x = 5x
Collect like terms
9x - 5x = 4
4x = 4
x = 4/4
x = 1

The answer is 6 1/2 buckets.
What is did was turn the fractions into decimals to make it easier.
So the ratio is 5.25 gallons per bucket. I divided 34 1/8 by 5 1/4 in decimal form (34.125/5.25) and got 6.5
So therefore, the answer is 6 1/2 buckets of water is needed ti fill up the tub.
