Answer: 8/9
Step-by-step explanation:
The common multiple they all share is 18, so change the denominator to that for all the fractions.
2/3 = 12/18
13/18 = 13/18
7/9 = 14/18
5/6 = 15/18
The next answer would be 16/18 which is equivalent to 8/9
80.75 / 8.50 = 9.5
Sean worked 9 and a half hours.
Answer: $2000
Step-by-step explanation:
Variable cost = Change in cost ÷ Activity change
($2000 - $2000) ÷ (10000 - 8000) = $0
Fixed cost element = Final cost - Variable cost
$2000 - ($0.00 ×10000) = $2000
Therefore, the cost formula for total maintenance is $2000 plus $0 per hour
y = $2,000 + $0x
At a level of 8,700 machine-hours, the total cost is:
y = $2000 + ($0.00 ×8700) = $2000
An angle bisector is one that cuts an angle into two equal halves.
bearing in mind that a degree has 60 minutes and a minute has 60 seconds, so then 171°30' is just 171 degrees and 30 minutes.
let's halve each, 171 ÷ 2 = 85.5°, so 85.5° is really 85° and half of another degree, let's recall that a degree has 60 minutes, so half of a degree is just half of 60 minutes, namely 30 minutes, so 85.5° is really 85°30'.
let's halve the 30 minutes now, half of 30 is 15, so 15 minutes is its half.
now let's add both halves together, 85°30' plus 15', 85°45'.
