I have no idea I am only in Middle School
Which question do you need
I think that 30 bulbs are expected to be defective.
Answer=Carlos
If Jackie has 10 groups, with 3 in each groups, she has 30 total pennies.
10*3=30 pennies
If Carlos has 5 groups with 100 in each group, then Carlos has 500 pennies.
5*100=500 pennies
500 pennies is more than 30 pennies, so Carlos has more pennies
The answer is 7 sections
In this type of question, you just need to divide the total length of the line that drawn by Jason with the length of sections that Jason want.
So, the calculation would be:
(7/8) / (1/8)
= 7/8 x 8/1
= 7 amount of sections
