Answer:
D
Step-by-step explanation:
The formula we need to solve this is:
Where
is the distance from one focus to the vertex
is the second distance from another focus to same vertex
<u>Note:</u> Here, vertex point is the point on top. The common point from which the RED and BLUE line meets the 2 foci
is half the length of the major axis (which is 9 here since total major axis is given as 18)
<em>Now we can plug into the equation and solve:</em>

<em>D is the correct answer.</em>
The average speed of his trip is = 12 mile/ hour
The total distance covered by the driver = 240 miles
The rate at which he traveled = 12 miles per hour
Therefore, the time he used to cover his distance
= 240/12
= 20 hrs
But average speed = distance/ time
= 240/ 20
= 12 miles/ hour
Therefore, the average speed of his trip is = 12 mile/ hour

For this question we can solve it by setting up a proportion:
Now we can solve for x to find the total distance between the towns. Let's cross multiply and solve for x:
So now we know that
the total distance between the towns is 42.5 miles.
Answer:
x = 28
Step-by-step explanation:
It gives you the value of the midsegment, which is 16. So you need to set up the equation as:
x + 4 = 2 × 16
You're multiplying 16 (the midsegment) by 2, because the it is <em>half</em> of x + 4, and you need to be able to set both parts of the equation equal to each other.
x + 4 = 32
Then, subtract 4 from both sides:
x + 4 = 32
-4 -4
_________
This gives you the answer of:
x = 28
All except for the third option are correct
