It will take 1274  revolutions to cover 1200 meters

The circumference (or) perimeter of a circle = 2πr units. The area of a circle = πr2 square units. Where r is the radius of the circle. The circumference of the circle or the perimeter of the circle is the measurement of the boundary of the circle. Whereas the area of the circle defines the region occupied by the circle.

Given here: The diameter of a child's bicycle wheel is 12 inches.

The diameter of the wheel is 12 inches=0.30 m

∴ circumference=3.14 ×0.3

                           =0.942

Therefore the number of revolutions are = 1200/0.942

                                                                    = 1274

Hence, It will take 1274  revolutions

Answer:

its 1254 revolutions

Step-by-step explanation:

you multiply 39.3701 by 1200 which gives 47,244.12 and you multiply 12 by 3.14 and that gives 37.68 so you then divide 47,244.12 by 37.68 which will give you a very long decimal including 1253 which becomes rounded to 1254

Answer: D. 1254 revolutions

Answer:

x = √22

Step-by-step explanation:

This is a right triangle.

In right triangles the sum of square value of legs is equal to the square value of hypotenuse:

[tex]( { \sqrt{11}) }^{2} + ( \sqrt{11} {)}^{2} = {x}^{2} [/tex]

[tex]11 + 11 = {x}^{2} [/tex]

Given:

The triangle FCP is reflected across the line x = 4.

See the attached with both FCP and F'C'P' triangles shown.

The x-coordinates are 1 unit apart from the x = 4 line, hence the new coordinates are 2 units less or greater than the original one and the y-coordinates remain as is.

Reflected points:

Answer:

F' = (5, -5)

C' = (5, -4)

P' = (3, -4)

Step-by-step explanation:

When an object is reflected over a vertical line, the x-value changes but the y-value does not change.

To reflect points across x = 4, determine the distance of the x-value of each of the points to the line of reflection by subtracting 4 from the x-values:

Point F is located 1 unit to the left of the line of reflection.  Therefore, the reflection of this point is 1 unit to the right of the line of reflection.  So the reflection of point F is 2 units to the right of point F:

As point C has the same x-value as point F, the x-value of its reflection in the line of reflection will be the same as point F:

Finally, point P is located 1 unit to the right of the line of reflection.  Therefore, the reflection of this point is 1 unit to the left of the line of reflection.  So the reflection of point P is 2 units to the left of point P:

0.5( -3)(-2x - 1/3+ 4 + 8x) and -1.5(12x -7) expressions are not equivalent

given that

first expression = 0.5( -3)(-2x - 1/3+ 4 + 8x)  and

In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context. Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

now we need to solve the first expression

2 students did not attend the Sports Day.

In mathematics, a fraction is used to denote a portion or component of the total. It stands for the proportionate pieces of the whole. The numerator and denominator are the two components that make up a fraction.

Given that,

Total number of students in a class = 24

Total number of students chosen for drills = 7/14 = 7/14 *24 = 12

Total number of students chosen for various races = 4/16 = 4/16 *24 = 6

Total number of students chosen for gymnastics= 1/6= 1/6* 24 = 4

Thus, the Total number of students participating in sports day = 12+6+4 = 22

Hence, the Total number of students that did not attend sports day= 24 - 22 = 2

Therefore, 2 students did not attend the Sports Day

Correct question: Out of a class of 24 students, 7/14 of the total students were chosen for drills, 4/16 of the total students were chosen for various races, and 1/6 of the total took part in gymnastics. The rest of them did not attend the Sports Day.

The exponential value of a number is equivalent to the number which is multiplied by itself a particular set of times.

When we represent a number in the exponential form then we can say that its power has been raised by an exponent. The exponential form is an easier way of representing repeated multiplication involving base and exponents.

The number which is multiplied by itself is called the base and the number of times it is to be multiplied is the exponent.

For example, If we have to write the exponential form of a×a×a×a×a, we can write it as a base and the number of a's as the power that is

a×a×a×a×a = a⁵

a is the base

The general equation to find centre of a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius.

The location of a moving point on a plane such that its separation from a stationary point on the plane remains constant or fixed is described as a circle. The centre of the circle is the name given to the fixed point

A circle's centre and radius make up its 2D shape. Knowing the circle's centre and radius allows us to draw any circle. The number of radii that a circle can have is unlimited. The intersection of all the radii constitutes the centre of a circle. It is also known as the centre of the circle's diameter.

The general equation of a circle is another name for the centre of circle formula. If the radius is r, the center's coordinates are (h,k), and any point on the circle is (x,y), the centre of the circle formula is as follows:

(x - h)2 + (y - k)2 = r2

2 = r2

Also known as center of the circle equation. we'll use this formula to determine a circle's equation or centre.

The measure of central tendency that is likely to vary least between the first and second samples of 30 scores is the median.

The median is less affected by outliers and variations in the sample compared to the mean and mode, making it less likely to vary between samples.

The median is a measure of central tendency that represents the middle value of a dataset when it is ordered by value. It is a robust statistic, which means that it is not easily affected by outliers or variations in the sample. This is because the median only looks at the middle value of a dataset, and does not take into account the values of the entire dataset, unlike the mean.

The mode, on the other hand, is the value that appears most frequently in a dataset. It is affected by variations in the sample because it is based on the frequency of values. A different sample of the same population may have a different distribution of values, resulting in a different mode.

The mean is the sum of all the values in a dataset divided by the number of values. It is affected by outliers, as a single large or small value can greatly affect the mean. In small samples, the mean can be affected by small variations in the sample.

In conclusion, since the median is based only on middle value of the sample, it is less affected by variations in the sample and outliers, making it less likely to vary between samples.

The area of a rectangle is -

Area = Length x Breadth

A = L x B

Given is the perimeter of a rectangle is 108 ft. Also the length is 24 ft more than the width.

We can write the length is equivalent to -

x {length} = y {width} + 24

The perimeter will be -

2(x + y) = 108

x + y = 54

y + 24 + y = 54

2y = 30

y {width} = 15 ft
