In 2015, a company made 2.7×10^11 mailboxes. in 2019, the same company made 3.9×10^12 mailboxes. how many more mailboxes did they make in 2019? (write your answer in scientific notation.)

3,630,000,000,000‬ more (3.93*10^12)

Step-by-step explanation:

2.7*10^11= 270,000,000,000

3.9*10^12= 3,900,000,000,000‬

3,900,000,000,000‬-270,000,000,000=3,630,000,000,000‬

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
