IgorLugansk [536]

Answer:

The horizontal distance between the parking lot and the launch site is 470 meters

Step-by-step explanation:

Let

x----->  the horizontal distance between the parking lot and the launch site

we know that

The tangent of angle of 12 degrees is equal to divide the altitude of 100 meters by the horizontal distance

so

tan(12°)=100/x

Solve for x

x=100/tan(12°)=470 meters

Jackrabbits are capable of reaching speeds up to 40 miles per hour. How fast is this in feet per second? (Round to the nearest w
Sonja [21]
To solve this problem, we are going to use a scientific/mathematics strategy called Dimensional Analysis.

40 miles / 1 hour * 5280 feet / 1 mile = 211200 feet / 1 hour

211200 feet / 1 hour * 1 hour / 60 minutes = 3520 feet/ 1 minute

3520 feet / 1 minute * 1 minute / 60 seconds = approximately 59 feet / 1 second


Jackrabbits travel approximately 59 feet per second, when rounded to the nearest whole number.
