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>

Answer:
90 centimetres per day
Step-by-step explanation:
Given that:
One of the Bamboo species growth can be seen.
Growth in of a day = 30 cm
To find:
The growth per day in centimetres as a proper fraction, mixed number or whole number.
Solution:
If we are given that:
The growth of a bamboo tree is centimetres in number of days.
Then growth per day can be found by dividing the total growth of bamboo tree by the number of days.
Formula can be written as:
Growth per day =
We are given that:
Putting the values, we get:
Answer:
If A and B are two rational numbers such that A<B
Then X = A + (B-A)/π would be an example of an irrational number
such that A < X < B

Image vertices are mathematically given as:
- A' = (-12 , 4)
- B' = (16 , -12)
- C' = (8 , 12)
- D' = (-4 , 16)
<h3>What are the image vertices for dilation with the center?</h3>
Generally, Multiplying the vertices by a scale factor of four is required in order for us to locate the picture vertices for dilation with center (0, 0).
In conclusion,, the image vertices are :
- A' = (-12 , 4)
- B' = (16 , -12)
- C' = (8 , 12)
- D' = (-4 , 16)
