Answer: 200 bulbs will not be defective.
Step-by-step explanation:
The ratio of defective bulbs to good bulbs produced each day is 2 to 10. This ratio can also be expressed as 1 to 5 by reducing to lowest terms.
The total ratio is the sum of the proportions.
Total ratio = 1 + 5 = 6
This means that if n bulbs is produced, the number of defective bulbs would be
1/6 × n
The number of non defective would be
5/6 × n
Since n = 240, then the number of bulbs that will not be defective is
5/6 × 240 = 200 bulbs
Your line will be vertical through the line 6 on the x axis, points- (6,0), (6,1), (6,2) etc..
-/7? imagine that there is an -1 as the numerator. so now -/7 turns into -1/7
Answer:
18 seconds
Step-by-step explanation:
8:10 = 4:5, 4+5 = 9, 9 x 2 = 18 seconds :D
X=one dollar
y=5 dollar
x=3y
1x+5y=40
3y+5y=40
8y=40
divide 8
y=5
x=3y
x=3(5)
x=15
15 one dollars
5 five dollars
