The area of the pier is approximately 1231.62 square meters.

A circle is a two-dimensional figure with a radius and circumference of 2pir.

The area of a circle is πr².

We have,

The pier is in the shape of a semicircle.

So,

The area of a semicircle is half of the area of a circle with the same diameter.

The area of a circle with a diameter of 56m is:

A = πr² = π(28)² = 2463.23 m²

So,

The area of the semicircle is:

A/2 = 2463.23/2= 1231.62 m²

Therefore,

The area of the pier is approximately 1231.62 square meters.

Answer:

When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side! This is why you must flip the sign whenever you multiply by a negative number.

Answer:

The length of the arc is approximately 2.0944

Step-by-step explanation:

The given parameters are;

The equation of the circle = x² + y² = 1

The radius of the circle, r = 1

The equation of the line, y = 1/2

Therefore, we point where the line intersects with the circle are given as the points 'y = 1/2' as follows;

When y = 1/2, the equation of the circle becomes;

x² + (1/2)² = 1

x² = 1 - (1/2)² = 3/4

x = ±√3/2

The angle subtended by the arc, θ = 2 × arctan((√3/2)/(1/2)) = 120°

The circumference of the circle, C = 2·π·r

∴ C = 2 × π × 1 = 2·π

The length of the arc, l = (θ/360) × C

∴ l = (120/360) × 2·π = (2/3)·π

The length of the arc, l = (2/3)·π ≈ 2.0944

The length of the arc is approximately 2.09

From the question, we have the following parameters

The equation of the circle = x² + y² = 1

The radius of the circle, r = 1

The equation of the line, y = 1/2

The line intersects with the circle are given as the points 'y = 1/2' as follows;

When y = 1/2, the equation of the circle becomes;

x² + (1/2)² = 1

x² = 1 - (1/2)² = 3/4

x = ±√3/2

Determine the subtended angle

The angle subtended by the arc is expressed as:

θ = 2 × arctan((√3/2)/(1/2))

θ = 120°

The circumference of the circle, C = 2·π·r

C = 2 × π × 1 = 2·π

The length of the arc, l = (θ/360) × C

l = (120/360) × 2·π = (2/3)·π

The length of the arc, l = (2/3)·π ≈ 2.09

The length of the arc is approximately 2.09

Answer:

1/20

Step-by-step explanation:

Karina ate 1/2 of the muffins. Ulysses ate 1/4 of the muffins. Zawanna ate 1/5 of the muffins. Juan ate the rest of the muffins. What fraction of the muffins did Juan eat?

Let the total number of muffins = 1

Hence:

The fraction of muffins Juan ate =

1 - (1/2 + 1/4 + 1/5)

Lowest common denominator is 20

1 - ( 10 + 5 + 4/20)

1 - 19/20

= 1/20

The Fraction of muffins Juan ate is 1/20

Given:

A figure of a kite.

To find:

The area of the given kite.

Solution:

The area of a kite is the half of the product of its diagonals.

[tex]A=\dfrac{d_1d_2}{2}[/tex]             ...(i)

Where, [tex]d_1,d_2[/tex] are two diagonals of the kite.

From the given figure it is clear that the length of one diagonal is the sum of 12 and 8.

[tex]d_1=12+8[/tex]

[tex]d_1=20[/tex]

Let the second diagonal be 2x. The first diagonals bisect the second diagonal. So, the length of one parts of the diagonal is x.

Diagonals of a kite are perpendicular to each other. Using Pythagoras theorem, we get

[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]

[tex]13^2=x^2+12^2[/tex]

[tex]169-144=x^2[/tex]

[tex]25=x^2[/tex]

[tex]5=x[/tex]

The length of second diagonal is:

[tex]d_2=2x[/tex]

[tex]d_2=2(5)[/tex]

[tex]d_2=10[/tex]

Substituting [tex]d_1=20,d_2=10[/tex] in (i), we get

[tex]A=\dfrac{20\times 10}{2}[/tex]

[tex]A=\dfrac{200}{2}[/tex]

[tex]A=100[/tex]

Therefore, the area of the kite is 100 square units.

An algebraic equation is "a mathematical statement in which two expressions are set equal to each toher."

Answer:

x=4,y=3

Step-by-step explanation:

x=19-5y if we transpose equation 2 for x.

Plug that into equation 1

4(19-5y)+3y=25

76-20y+3y=25

76-25=17y

51=17y

y=3

Plug y=3 into equation 2

x+5(3)=19

x=19-15=4

We are having two equations,

★ From Equation No 2 :-

>> x + 5y = 19

>> x = 19 - 5y

★ From Equation No 1 :-

Substitute here the value of x which we got above as (19 - 5y).

>> 4x + 3y = 25

>> 4 (19 - 5y) + 3y = 25

>> 4 × (19 - 5y) + 3y = 25

>> 76 - 20y + 3y = 25

>> 76 - 17y = 25

>> -17y = 25 - 76

>> -17y = -51

>> 17y = 51

>> y = 51 / 17

>> y = 3

★ Finding out value of x :-

>> x = 19 - 5y

>> x = 19 - 5(3)

>> x = 19 - 5 × (3)

>> x = 19 - 15

>> x = 4

Answer:

We know that for every (3/4) cups of sugar, she uses (1/2) cups of flour.

Now let's find how much flour she needs to use for each case:

If she uses (1/8) cups of sugar, how much flour she uses?

First, we need to count how many times we have (3/4) cups of sugar in (1/8) cups of sugar, which is the quotient:

(1/8)/(3/4) = 4/(3*8) = 4/24 = 1/6

This means that we need to use (1/6) times (1/2) cups of flour.

this is:

(1/6)*(1/2) cups of flour = (1/12) cups of flour.

If she uses (4/3) cups of sugar, we need to count how many times we have (3/4) cups of flour in that amount, this is:

(4/3)/(3/4) = (4*4)/(3*3) = 16/9

Then we need to se (16/9) times (1/2) cups of flour, this is:

(16/9)*(1/2) cups of flour = (16/18) cups of flour = (8/9) cups of flour

If she uses (1/2) cups of sugar, we need to count how many times we have (3/4) cups of sugar in that amount, this is:

(1/2)/(3/4) = 4/(2*3) = 4/6

Then she needs to use (4/6) times (1/2) cups of flour

this is:

(4/6)*(1/2) cups of flour = 4/(6*2) cups of flour = (1/3) cups of flour.

If she uses (1/4) cups of sugar, we need to count how many times we have (3/4) cups of sugar in that amount, this is:

(1/4)/(3/4) = 4/(4*3) = 4/12

Then she needs to use (4/12) times (1/2) cups of flour

this is:

(4/12)*(1/2) cups of flour = 4/(12*2) cups of flour = (1/6) cups of flour.

If she uses (1/5) cups of sugar, we need to count how many times we have (3/4) cups of sugar in that amount, this is:

(1/5)/(3/4) = 4/(5*3) = 4/15

Then she needs to use (4/15) times (1/2) cups of flour

this is:

(4/15)*(1/2) cups of flour = 4/(15*2) cups of flour = (2/15) cups of flour.

The interquartile range (IQR) of the data set is 24 degrees Celsius.

The interquartile range (IQR) is a measure of variability or spread in a dataset. It is the difference between the third quartile (Q'') and the first quartile (Q) of the dataset.

To calculate the interquartile range (IQR) of this data set, we first need to find the first quartile (Q) and the third quartile (Q'').

Arrange the data in order from smallest to largest:

08, 09, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48

Find the median (Q') of the entire data set:

Median (Q') = (24 + 28)/2 = 26

Find Q by taking the median of the lower half of the data:

Lower half: 08, 09, 12, 16, 20, 24

Q = (12 + 16)/2 = 14

Find Q'' by taking the median of the upper half of the data:

Upper half: 28, 32, 36, 40, 44, 48

Q'' = (36 + 40)/2 = 38

Calculate the IQR by subtracting Q from Q'':

IQR = Q'' - Q = 38 - 14 = 24

Therefore, the interquartile range (IQR) of this data set is 24 degrees Celsius.
