Answers
Answer:
60 mph
Step-by-step explanation:

There are two halves in an hour so
30 x 2 = 60
Right △ABC has coordinates A(-7, 3), B(-7, 10), and C(-1, 3). The triangle is reflected over the x-axis and then reflected again over the y-axis to create △A'B'C'. Which are the coordinates of vertex A'?
Answers
X-axis = A (-7,-3) B (-7,-10) C (-1,-3) first they changed to the x-axis which is this. Just so you know on the x-axis the x-axis stay and the y-axis changed which is this. When they reflect again on the y-axis the verter of A' is A' (7, 3) = answer On the y-axis the y- axis doesnt change but the x-axis changed. Hope this help!
the answer is... (7,3)

Six hundredth, eighty-nineths? My best guess. You can also just say "point six hundred eighty-nine". The latter sounds better.

samantha drove 168 miles in 3 1/2 hours. she than drove the next 2 1/4 hours at a rate of 5 miles an hour faster than the first rate. how many miles did samanha drive durigthe 5 3/4 hours?
Answers
3.5 hours = 168 mi
We need to figure out the miles per hour pace first, before we move on any further.
To do this, divide 3.5 on both sides so we get per ONE hour: 3.5 hours/3.5 = 168 mi/3.5
1 hour = 48 mi
That means for the first 3.5 hours, Samantha drove at a pace of 48 miles per hour. If she were to drive 5 miles an hour faster the next 2.25 hours, that means she would be driving at 53 miles per hour.
Now we need to find the total number of miles Samantha drove. For the first 3.5 hours, she drove 168 miles.
For the next 2.25 hours, she drove at a pace of 53 miles per hour.
If 53 mi = 1 hour, we need to multiply 2.25 on both sides to find out how many miles is 2.25 hours.
53 mi x 2.25 = 1 hour x 2.25
53(2.25) mi = 2.25 hours
Simplify
119.25 mi = 2.25 hours
That means Samantha drove 119.25 miles for those 2.25 hours.
To find the total number of miles, we need to add them up:
168 + 119.25 = 287.25
So Samantha drove a total of 287.25 miles during the 5.75 hours :)
