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.

3.  x+100 = 90   alternate interior angles are equal

subtract 100 from each side

x+100 - 100 = 90-100

x = -10


4.  17x+1 = 120    alternate exterior angles are equal

subtract 1 from each side

17x+ 1 -1 = 120 -1

17x = 119

divide each side by 17

17x/17 = 119

x =7

9. A rectangle has a length 2 ft less than three times its width. What is the area of the rectangle when its
Burka [1]

Answer:

Area = 8 square ft

Step-by-step explanation:

Area of a rectangle = Length × width

suppose length = x

width  = y

Here it is given that  x = 3 y - 2

             width is given as y = 2 ft

            ∴ x = 3 × 2 -2

              x = 6 -2

              x = 4

 Area of rectangle = length × width

                              A = 4 × 2

                                 = 8 square ft
