Answers

Answer:

18 hours

Step-by-step explanation:

Let the number of hours used to represented by x

Gloria subscribes to the Webtime Internet Service. Webtime charges a $9.99 monthly service fee plus $1.50 per hour for Internet access.

Total bill = $9.99 + $1.50 × x

= 9.99 + 1.5x

Last month's bill was $ 36.99.

Hence,

9.99 + 1.5x = 36.99

Collect like terms

1.5x = 36.99 - 9.99

1.5x = 27

x = 27/1.5

x = 18 hours

The number of hours that Gloria used the Internet last month is 18 hours

A roller coaster can hold 32 people at a time. There are 275 people waiting to ride the roller coaster. How many trips will the roller coaster have to make for all the people to ride?

Answers

Answer:

9

Step-by-step explanation:

275 divided by 32 in equal to 8.59, so you just have to round up  but that last trip just wont be full

Answer:

9 roller coaster rides. hope this helps!

Step-by-step explanation:

A roller coaster can hold 32 people at a time.

there are 275 people waiting in line.

How many trips will it take for there to be 0 people waiting in line?

We know the roller coaster can hold 32 people at a time, and 275 people are waiting in line.

275/32=8 rides and 19 people left.

If you don't know how to do that: 275 people at first. 275-32 because the roller coaster can only hold 32. Repeat that process untill you find your answer.    

So we have 8 rides, and 19 people left? It doesn't matter, It will not take, half the time left, or more time to get it done. So anything below or equal to 32 people will take the same amount of time. So our final answer is 9 rides. Not 8.59375.

He no longer marched. At once he became a thing of the wild, stealing along softly, cat-footed, a passing shadow that appeared and disappeared among the shadows. He knew how to take advantage of every cover, to crawl on his belly like a snake, and like a snake to leap and strike. He could take a ptarmigan from its nest, kill a rabbit as it slept, and snap in mid air the little chipmunks fleeing a second too late for the trees. Fish, in open pools, were not too quick for him; nor were beaver, mending their dams, too wary. He killed to eat, not from wantonness; but he preferred to eat what he killed himself. So a lurking humor ran through his deeds, and it was his delight to steal upon the squirrels, and, when he all but had them, to let them go, chattering in mortal fear to the treetops.Which theme does this passage illustrate?
