A Circular Field Was Fenced Using 66 Posts Placed Two Metres Apart What Is The Area Of The Field In Square
Answer 2

The area of the circular field in square meters will be equal to, 1386 m².

What is the area?

An object's area is how much space it takes up in two dimensions. It is the measurement of the number of unit squares that completely encompass a compact figure's surface. The squared unit, which is frequently expressed as inches, square feet, etc., is the accepted unit of area.

As per the given information in the question,

Total number of posts = 66

Distance between two posts = 2 meters

Then, the circumference of the area will be,

= 66 × 2 = 132 meters

Now, let's find the radius of the circle,

C = 2πr

132 = 2 × 3.14 × r

r = 132/(2 × 3.14)

r = 21.01 m

Use the formula for the area of the circle:

A = πr²

A = 3.14 × (21.01)²

A = 441.420 × 3.14

A = 1386 m²

To join a new fitness center, there is a $40 initiation fee. It costs an additional $10 for every spinning class you attend. What is the average cost per class if you take 10 classes in the first month of joining the fitness center

Answers

the average cost per class is $14.

Think of this as an algebraic equation, which would be expressed as 40+10s=total cost

The (s) would be the number of spinning classes you decide to take.

Therefore to find the average cost of the class, you would plug in 10 classes for s.

This brings the total cost to $140 dollars.

To find the average you must divide this cost by the number of classes you took.

This will be the price per class, which is $14.

So, we have:

JK = JL + LK

Substitute JL = LK

JK = JL + JL

This gives

JK = 2JL

What are Coordinates ?

Coordinates are the location of a point on the x-y plane.

It is given that the coordinates of C are  (4,4)

the midpoint of CD is at M(-2,-6)

The distance between D to the midpoint is equal to distance between C and the mid point M .

The distance between C and M is

Find two numbers such that one number is 3 less than twice as big as the other number and the two numbers sum to 21.

Answers

Answer:

The two numbers are:

a + b = 21        Eq. 2

Replacing Eq. 1 in Eq. 2:

(2b-3) + b = 21

3b - 3 = 21

3b = 21 + 3

3b = 24

b = 24/3

b = 8

from Eq. 1

a = 2*8 - 3

a = 16 - 3

a = 13

Answers

Using the given linear function of best-fit, the most likely approximate height of the plant after 8 weeks would be of 7.4 centimeters.

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

The line of best-fit goes through points (0,1) and (5,5). Point (0,1) means that the y-intercept is of b = 1. The slope is given as follows:

m = (5 - 1)/(5 - 0) = 4/5 = 0.8.

Hence the equation that gives the approximate height after x weeks is:

y = 0.8x + 1.

After 8 weeks, the expected height is:

y = 0.8 x 8 + 1 = 6.4 + 1 = 7.4 centimeters.

What is Speed?The most crucial scientific notion is measurement. Base or physical fundamental units are used to quantify a wide range of quantifiable quantities. One such measurable metric is speed, which calculates the ratio between the distance an object travels and the time needed to cover that distance. Let's explore speed in-depth in this session. The pace at which an object's location changes in any direction. When an object travels the same distance in the same amount of time, it is said to be moving at a uniform speed. When an object travels a different distance at regular intervals, it is said to have variable speed.

We know the formula of distance linking the speed and the time.

Distance = speed × time
