Answer: The Area of Shaded Region is 576  [tex]cm^{2}[/tex] and the perimeter is 24 (2 + [tex]\pi[/tex]) cm

Step-by-step explanation: Given, the length of the line segment BC is 24 cm.

     First, The area of the Semi Circle AD : We know that area of a circle is [tex]\pi[/tex][tex]r^{2}[/tex]  where r=radius of the circle. Since the shape ABCD is a sqaure, BC=AD=24cm. We can see from the figure that AD is the diameter for the semi circle AD. And diameter = 2 x Radius. Therefore radius of the semi circle is 12cm.

Therefore, area of the first Semi circle AD will be :

⇒ [tex]\pi \frac{r}{2}cm ^{2}[/tex]

⇒([tex]\pi[/tex]*12*12)/2

⇒72[tex]\pi[/tex] [tex]cm^{2}[/tex]

Now, perimeter of semi circle AD : We know perimeter of a Semi circle is [tex]\pi[/tex]r + length of the base.

Therefore, perimeter of Semi circle AD is :

⇒[tex]\pi[/tex]*12 + 24 cm

⇒12 (2 + [tex]\pi[/tex])

Now, Area of the Shape ABCD, As we can see from the figure, The area will be Area of square ABCD - Area of the semi circle BC. Therefore,

Area of Square = [tex]side^{2}[/tex]

⇒24 x 24 [tex]cm^{2}[/tex]

Area of semi circle BC :

⇒(12 x 12 x [tex]\pi[/tex])/2 [tex]cm^{2}[/tex]

∴ Area of shape ABCD = [(24 x 24) - (12 x 12 x [tex]\pi[/tex])/2] [tex]cm^{2}[/tex]

⇒576 - 72[tex]\pi cm^{2}[/tex]

Now, Perimeter of Shape ABCD :

We can see from figure, the perimeter will be Sum of 3 sides of the square and the circumference of the semi circle BC.

Therefore,

⇒72 + 12[tex]\pi[/tex] cm

Now, Finally The Area of the shaded region :

⇒ Area of Shape ABCD + Area of Semi circle AD

⇒[576 - 72[tex]\pi cm^{2}[/tex]] + [72[tex]\pi[/tex] [tex]cm^{2}[/tex]]

⇒576 [tex]cm^{2}[/tex]

Perimeter of the shaded region :

⇒ Sum of 2 sides of the square ABCD + 2 Times the Circumference of the semi circle

⇒[24 + 24] + [2 x 12[tex]\pi[/tex]]cm

⇒ 24 (2 + [tex]\pi[/tex]) cm, Final Answer

Answer:

G.1/4

Step-by-step explanation:

The probability of getting two heads when two fair coins are tossed is 1/4 or 0.25. This is because for each coin there are two possible outcomes, heads or tails, and the probability of getting heads is 1/2. Therefore, the probability of getting two heads when both coins are tossed is (1/2) * (1/2) = 1/4. So the correct answer is G. 1/4

The ratio of the lengths of the parallel sides of the trapezoid CD/AB = 13

A trapezoid is a quadrilateral that has a pair of parallel sides.

The median line of a trapezoid is the line joining the midpoint of the non parallel sides of a trapezoid

The parallel sides of the trapezoid are; AB and CD

The area of trapezoid ABMN = 8

Area of trapezoid NMCD = 20

The ratio of the lengths of the parallel sides, CD/AB is found as follows;

The length of the median, MN = (1/2) × (AB + CD)

Area of a trapezoid = (The sum of the length of the parallel sides) × (The distance between the parallel sides) ÷ 2

Area of the trapezoid ABCD = [ABMN]  + [NMCD]

[ABCD] = 8 + 20 = 28

Area of trapezoid [ABCD] = NM × h = 28

The height of trapezoid ABNM = h/2

Height of trapezoid NMCD = h/2

[ABNM] = ((AB + NM)/2) × (h/2)

[ABNM]  = ((AB × h + NM × h)/4) =  ((AB × h +28)/4) = 8

(AB × h + 28) = 4 × 8 = 32

AB × h = 32 - 28 = 4

AB × h = 4

[NMCD] = (NM + CD)/2 × (h/2)

[NMCD] = (NM × h + CD × h)/4 =  (28 + CD × h)/4 = 20

CD × h = 20 × 4 - 28 = 52

CD × h = 59

(CD × h)/(AB × h) = 52/4 = 13

CD/AB = 13

Answer:

5/8 is greater than 5/7. 5/8 is 0.625, while 5/7 is 0.714.

Step-by-step explanation:

5/8 is greater than 5/7. 5/8 is 0.625, while 5/7 is 0.714.

Answer:

5/7

A fraction is a fragment of a whole number, used to define parts of a whole.  The whole can be a whole object, or many different objects. The number at the top of the line is called the numerator, whereas the bottom is called the denominator.

If we think about 5/7, we can relate this to a circle split into 7 parts, with 5 shaded in.

You can do the same for 5/8. Think of a circle with 8 parts, and 5 shaded in.

A way to figure out which is bigger is to find a common denominator between the two.

A common denominator is two fractions with the same denominator (Hence the name). Solving for a common denominator can be done with cross multiplication.

5/7 = 40/56

5/8 = 35/56

We can visibly see, that 40/56 (5/7) is bigger, therefore making 5/7 the greater fraction.

The rate of change of the volume at that particular instant is - 62.8 m^3/h.

How to get the rate of change of the volume?

First, we can write the dimensions as:

radius = R = (5m + 1m/h*t)

height = H = (8m - 4 m/h*t)

Where t is the time in hours.

Then the volume of the cylinder will be:

V = pi*R^2*H = 3.14*(5m + 1m/h*t)^2*(8m - 4 m/h*t)

To get the rate of change, we need to differentiate it with respect to t, we will get:

V' = 3.14*(2*(5m + 1m/h*t)*(1m/h)*(8m - 4 m/h*t) + (5m + 1m/h*t)^2*(-4m/h))

V' = 3.14*( (2 m/h)*(5m + 1m/h*t)*(8m - 4 m/h*t) - (4m/h)*(5m + 1m/h*t)^2)

V' = 3.14*(2m/h)*( (5m + 1m/h*t)*(8m - 4 m/h*t) - 2*(5m + 1m/h*t)^2)

As you can see the rate of change depends on t, but we want the rate of change at this instant, then we use t = 0, replacing that on the above equation we get:

V'(0) = 3.14*(2m/h)*( (5m + 1m/h*0)*(8m - 4 m/h*0) - 2*(5m + 1m/h*0)^2)

V'(0) = 3.14*(2m/h)*( (5m)*(8m ) - 2*(5m)^2)=  -62.8 m^3/h

The statement that when algebraic or numerical fractions are added or subtracted, the result is a single fraction is True.

For addition or subtraction of algebraic or numerical fractions, the denominator has to be the same for all terms in the equation.

For common denominator,

Suppose 2 numerical fractions are being added which have a common denominator: 3/5 + 1/5

The resultant fraction will be 4/5, which is a single fraction

For algebraic fractions, considering the denominators are common, such as 3x/5 + 4x/5 = 7x/5

The result is also a single fraction.

For different denominators,

Suppose 2 numerical fractions are being subtracted which have different denominators such as, 5/9 – 3/7

In this case, the least common multiple for the denominators are calculated: 9*7= 63, and the opposite numerators are multiplied to the opposite denominators

Therefore, (5*7 – 3*9)/63 = (35 – 27)/63 = 8/63, which gives us a single fraction.

The process is same for algebraic fractions, for example,

4x/7 – 3x/5 = (4x*5 – 3x*7)/35 = (20x – 21x)/35 = -x/35, which is also a single fraction.

June has 27 coins, made up of quarters and dimes. in total, the coins are worth $4.20. Therefore, there are 10 quarters and 17 dimes she have.

Dime Coin:

A cent is a dime in US parlance, one tenth of the US dollar, and is officially called a "one cent". The name was first authorized by the Money Act of 1792.

The 10-cent coin is the smallest in diameter and the thinnest US coin in circulation, measuring 17.91 mm (0.705 inches) and 1.35 mm (0.053 inches) in diameter thickness. The obverse of the current cent features a profile of President Franklin D. Roosevelt, while the reverse depicts, from left to right, an olive branch, a torch, and an oak branch.

Quarter Coin:

The quarter (short for quarter dollar) is a United States coin denominated in 25 cents (quarter dollar). The obverse of the coin depicts George Washington in profile, and since 1998 the design of the reverse has changed frequently. In continuous production from 1796 to 1831. 955 inches (24.26 mm), 0.069 inches (1.75 mm) thick. The current version consists of two layers of cupronickel (75% copper, 25% nickel) plated on a pure copper core. The overall composition of the coin is 8.33% nickel and 91.67% copper, as the cupronickel layer accounts for 1/3 of the total weight. Its weight is 0.1823 troy ounces or 0.2000 regular Dupo ounces (5,670 grams).

We can consider that:

Let d = the number of dimes

Let q = the number of quarters

Now,

   d + q = 27                        -------------------------- (1)

⇒ d = 27 - q                      

⇒ 0.10d + 0.25q = 4.20                -------------------------- (2)    

Multiply both sides of this equation by 100 to get rid of the decimal points.

10d + 25q = 420

⇒ 10(27- q) + 25q = 420

⇒ 270 - 10q + 25q = 420

⇒ 15q = 150

⇒ q = 10

Now, Putting the value of q = 10 in equation (1) :

   d + 10 = 27

⇒ d = 27 - 10

⇒ d = 17

Therefore, there are 10 quarters and 17 dimes she have.
