Mathematics
1 answer:
Lemur [1.5K]3 years ago
3 0

Answer:

First answer:

"<em>The sum is rational because both 1.12 and 18 are rational, and the sum of rational numbers is rational."</em>

Step-by-step explanation:

Both 1.12 and 18/7 are rational numbers (meaning that they can be written as a quotient of integer numbers:

1.12 = 112/100

Then, since the addition of rational numbers is also a rational number, their sum is another rational number.

Then the correct answer is:

<em>The sum is rational because both 1.12 and 18 are rational, and the sum of rational numbers is rational.</em>

A farmer measures the distance around a rectangular field. The length of each long side of the rectangle is found to be 20.33 m,
Tasya [4]
<h2>Answer:</h2>

<em><u>Distance of the farmer's rectangular field around the field = 74.46 m</u></em>

<h2>Step-by-step explanation:</h2>

In the given question,

Length of the rectangular field, L = 20.33 m

Width of the rectangular field, W = 16.9 m

Now,

The area of rectangular field is given by,

The total distance around the rectangular field is,

Distance = Perimeter of the the rectangle.

Perimeter of rectangle = 2(Length + Width)

Perimeter = 2(20.33 + 16.9)

Perimeter = 2(37.23)

Perimeter = 74.46 m

So,

<em><u>Distance of the farmer's rectangular field around the field is = 74.46 m</u></em>

diameter is 15 meters then radius is 15/2 = 7.5 meters

so the amplitude is 7.5 m and height will oscillate with amplitude 7.5 m above and below the center.

midline of the oscillation will be 7.5 m

the wheel.take 8 minutes to complete revolution then it means the height will oscillate with a period of 8 minutes
