From the given condition above, travelling from the northernmost part to the southernmost part would mean that the cars traveled half of the circumference of the circle. With the given value for the circumference of the circular track, the car traveled 1.35 km.
It is A because which ones are closer to each other
Using a system of equations, it is found that Carol is 10 years old.
The complete problem is:
"Gerrys age is 5 more than three times Carols age. If the sum of their age is 45, how old is carol?"
<h3>System</h3>
The variables are:
Gerry is <u>5 more than three times Carol's age</u>, hence:
![x = 5 + 3y](https://tex.z-dn.net/?f=x%20%3D%205%20%2B%203y)
The sum of their ages is 45, hence:
![x + y = 45 \rightarrow x = 45 - y](https://tex.z-dn.net/?f=x%20%2B%20y%20%3D%2045%20%5Crightarrow%20x%20%3D%2045%20-%20y)
We then use the first equation to find Carol's age:
![45 - y = 5 + 3y](https://tex.z-dn.net/?f=45%20-%20y%20%3D%205%20%2B%203y)
![4y = 40](https://tex.z-dn.net/?f=4y%20%3D%2040)
![y = \frac{40}{4}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B40%7D%7B4%7D)
![y = 10](https://tex.z-dn.net/?f=y%20%3D%2010)
Carol is 10 years old.

Answer:
5/8+ 5r = 1
Step-by-step explanation:
When his younger sister is impatient, Byron also uses the lawn sprinkler to add water to the pool so it is filled more quickly. If the hose and sprinkler are used together, it takes 5 minutes to fill the pool.
Where r = rate in parts per minutes
Hand held hose = 8 minutes
Lawn sprinkler = x
If the hose and sprinkler are used together, it takes 5 minutes to fill the pool.
Hence:
5/8+ 5r = 1
The equation can be used to determine r, the rate in parts per minute, at which the lawn sprinkler would fill the pool if used alone is given as:
5/8 + 5r = 1
The answer is the option d.Perpendicular bisector.
Explanation:
By definition, a circumscribe circle passes through the three vertices of the triangle and to its constrution, you have to draw the triangle and then construct a perpendicular bisector to each side of it. The point where these perpendicular bisectors intersect each other, will be the center of the circle. Then, you should place the compass on the center point to draw the circle.
