Answer:
A'B' = 7.5
Step-by-step explanation:
uhhh
AC = A'C'
4 = 6
×1.5
AB^2 = 4^2 + 3^2
AB^2 = 16 + 9
AB^2 = 25
AB = √25
AB = 5
A'B' = 5 × 1.5 = 7.5
Answer:
7.7
Step-by-step explanation:
To find the intersection points of the line and the circle we have to set up a system with their equations and solve. The system would look like this:
To solve, substitute 1 for x in the second equation to get:
Solving, we get:
Therefore, the two points of intersection are 
and 
. The distance between these two points (the length of the chord in the circle) is 
which is 7.745966692414... which is 7.7 rounded to the nearest tenth.
Hope this helps :)
Multiply 199 by 355 to give you 70,645. Then add 70,645 to 1068 to give you 71,713.
Answer:
<u>Sam would take to drive 500 miles in 4 hours and 34 minutes at the same speed.</u>
Step-by-step explanation:
It is easy to say that if Sam continues driving at the same speed it will take a little longer to drive the 500 miles.
If Sam drives 320 miles in 150 minutes (2.5 hours)
How long will it take to drive 500 miles at the same speed?
An equation called "rule of 3" can be applied:
320 miles = 150 minutes
500 miles = X?
X is cleared from the equation
X = (500 miles * 150 minutes) / 320 miles
X = 234.37 minutes
Now we spend 234.37 minutes at hours with the same rule of 3
1 hour = 60 minutes
X = 234.37 minutes
Clearing X would give
X = (1 hour * 234.37 minutes) / 60 minutes
X = 4 hours and 34 minutes
Sam would take 500 miles in 4 hours and 34 minutes
