Answer:
<em>n = 0</em>
Step-by-step explanation:
- 6(n - 3) = 18
n - 3 = 18 ÷ ( - 6)
n - 3 = - 3 ⇒ <em>n = 0</em>

Answer:
it will take them 3.6 hours if their speed is increased
Step-by-step explanation:
First of all, we will need to find the total distance the Geradi family will be travelling. This is a better way to start, as the distance is constant regardless of their change in velocity.
Distance travelled = speed of travel X time taken = 45 X 4 = 180 miles per hour.
If the Geradi family increases their speed to 50 miles per hour, their new time will be got by dividing the total distance travelled by this new speed.
New travel time = 180 miles / 50 miles per hour = 3.6 hours
Answer:
The distance between the tallest building and the statue is 5 miles, so as the statue is inside the range of 7 miles, it can be seen from the tallest building.
Step-by-step explanation:
To solve the problem we need to know the distance between the tallest building in the town and the statue.
This distance can be calculated with the formula of the distance between two points:
d = sqrt(dx^2 + dy^2), where dx is the difference in x-coordinate between the points and dy is the difference in y-coordinate between the points.
So, the distance between these points is:
dx = 5-2 = 3
dy = 1-5 = -4
d = sqrt(3^2 + (-4)^2) = sqrt(9+16) = 5 miles
The distance is 5 miles, so as it is inside the range of 7 miles, the statue can be seen from this point.
