21 minutes. Step-by-step explanation: Considering the following: Using CITY STREET: The duration to drive to the nearest bowling alley is 45 minutes, which is 0.75 hours. The travel speed is 30 miles per hour. Switching to FREEWAY: the travel speed here is 65 miles per hour. Assuming both routes cover the same distance, the time required on the FREEWAY will be as follows: The distance calculated using the city route results in 30 mph = distance / 0.75 hour, giving a distance of 22.5 miles. As the distance remains consistent: Time taken on the FREEWAY = distance / speed, which results in 22.5 / 65 = 0.3461538 hours. Converting to minutes = 0.3461538 × 60, which rounds to approximately 21 minutes.
surface area = 4 x pi x r^2
diameter is 1, thus radius = 1/2 = 0.5
4 x 3.14 x 0.5^2 = 3.14 square meters
Visualizing the scenario is advantageous; creating a diagram would show a right triangle where the base measures 100 ft and the height is 25 ft. We can easily determine the angle using trigonometric functions as follows:
tan(theta) = 25 / 100
theta = 14.04 degrees
10-3 or 10+(-3), these two forms should be helpful.
you have to multiply the number by how much it used to be then divide it, but if there is a remainder, then add a zero and combine it all together. I hope you understand and manage to solve it correctly.
