Answer:
<u>Kathy drove the first 9 hours of the trip and Brian drove the last 3 hours.</u>
Step-by-step explanation:
Let's review the information given to us to answer the question correctly:
Total distance of the trip = 750 miles
Time of the trip = 12 hours
Speed of Kathy = 65 mph
Speed of Brian = 55 mph
2. For what length of the time did Kathy and Brian drive?
Let's solve the problem, this way:
x = Time in hours Kathy drove
12 - x = Time in hours Brian drove
Now, let's write our equation to solve for x:
65x + 55 (12 - x) = 750
65x + 660 - 55x = 750
10x = 750 - 660
10x = 90
x = 90/10
x = 9 ⇒ 12 - x = 3
<u>Kathy drove the first 9 hours of the trip and Brian drove the last 3 hours.</u>
The volume of a prism is given by its base area multiplied by its height.
The bases are two right triangles. If we project everything on the xy plane, we can see that the vertices of the base triangle is
So, leg AB is 3 units long, and leg AC is 4 units long. This means that the area of the triangle is
The height of the prism connects, for example, points 
and 
, so it's 5 units long. So, the volume of the prism is
Answer: 1,6,11,16,21,26

The common difference is 5 (n+5)
Answer:
1 minute
you just have to divide 180m by 3m= 60s
Answer:
6
Step-by-step explanation:
because if it needs 4 for 120 then u would divide that and get 30 then divide 180 by 30 and get 6.
