Answer:

Area of the rectangle will be 24.520m^2

Explanation:

We have given sides of rectangle is 12 feet by 22 feet

We know that 1 feet = 0.3048 m

So 12 feet will be equal to 12×0.3048 = 3.657 m

And 22 feet will be equal to 22×0.3048 = 6.705 m

We have to find the area of the rectangle in square meter

Area of rectangle is equal to multiplication of sides of the rectangle

So area A =3.657\times 6.705=24.520m^2

Your average speed on the first half of a car trip is 69.0 km/h. How fast do you have to drive on the second half of the trip to
vova2212 [387]

Answer:

13 km/h

Explanation:

Average speed = distance/time

Let the total distance and total time taken for the whole trip be d km and t hours respectively

Average speed for the whole trip = 82 km/h

d = 82t

The distance covered in the first half = d1/2

Time taken = t/2

Average speed = 69 km/h

69 = d1/2 ÷ t/2

d1 = 69t

The distance covered in the second half = d2/2

Time taken = t/2

Let the average sly for the see half be A

A = d2/2 ÷ t/2

d2 = At

d = d1 + d2

82t = 69t + At

At = 82t - 69t

At = 13t

A = 13t/t = 13 km/h

Give an example of a compound machine. Explain how at least two simple machines are part of the complex machine. Thank you !!
kaheart [24]

A compound machine is a combination of at least two simple machines. Simple machines can be a lever, a wedge, a while + axle, an incline plane, a pulley, and a screw.

There are many examples of compound machines. One of them is a showel that combines a wedge (the scoop part of shovel) and a lever (the handle to transfer the force to lift).

A much more complex compound machine is a bicycle, comprising simple machines ranging from wheels and axles, to screws, and levers (think of the pedals).
