A grazing area for animals is in the shape of
a rectangle having length 8 m and breadth
6 m. A goat is tied with a rope at one corner
of the rectangle. Find the minimum length
of the rope so that the goat can cover the
entire area for grazing.

The surface area of a sphere can be determined from the radius by the equation of 4πr². Hence, the surface area of the sphere of 9 units is approximately 1017.36 square meters.

Surface area is the total area that covers the surface of a 3-dimensional object. It is a measure of how much area needs to be covered to completely wrap around the exterior of the object.

In other words, it is the sum of the areas of all the faces or surfaces that make up the object. The unit of measurement for surface area is typically square units, such as square centimeters, square meters, or square feet.

The formula for the surface area of a sphere is:

A = 4πr^2

Where A is the surface area and r is the radius of the sphere.

Substituting r = 9 units, we get:

A = 4π9²

A = 4π(81)

A = 324π

Therefore, the surface area of a sphere with a radius of 9 units is approximately 324π square units, or approximately 1017.36 square units if you round to two decimal places.

Answer:

The answer is Real numbers

Answer:

a) 21.43% (It is unusual to happen)

b) 21.43%

c) 57.14%

d) Probability of you liking both songs played = 25%

Probability of liking exactly one song = 50%

Step-by-step explanation:

a)

If you like 4 of the 8 songs, the probability of liking the first song is 4/8

Then, for the second song, we have 3 songs you like among 7 songs that can be played, so the probability is 3/7.

So the probability of you liking both songs played is:

P = (4/8) * (3/7) = 0.2143 = 21.43% (It is unusual to happen)

b)

If you like 4 of the 8 songs, you dislike 4 as well, so the probability of not liking the first song is 4/8.

Then, for the second song, we have 3 songs you dislike among 7 songs that can be played, so the probability is 3/7.

So the probability of you disliking both songs played is:

P = (4/8) * (3/7) = 0.2143 = 21.43%

c)

In this case you can like either the first or the second song, so we need to sum the probabilities of both cases:

Probability of liking the first song and disliking the second:

P1 = (4/8) * (4/7) = 0.2857

Probability of disliking the first song and liking the second:

P2 = (4/8) * (4/7) = 0.2857

P = P1 + P2 = 0.5714 = 57.14%

d)

If a song can be replayed, we have:

Probability of you liking both songs played:

P = (4/8) * (4/8) = 0.25 = 25%

Probability of liking the first song and disliking the second:

P1 = (4/8) * (4/8) = 0.25

Probability of disliking the first song and liking the second:

P2 = (4/8) * (4/8) = 0.25

P = P1 + P2 = 0.5 = 50%

Answer:

x =  -2  ±sqrt( 19)

Step-by-step explanation:

x^2 + 4x = 15

Take the coefficient of x

4

Divide by 2

4/2 =2

Square it

2^2 = 4

Add it to each side

x^2 + 4x+4 = 15+4

(x+2)^2 = 19

Take the square root of each side

sqrt( (x+2)^2) =±sqrt( 19)

x+2 =  ±sqrt( 19)

Subtract 2 from each side

x+2-2 = -2  ±sqrt( 19)

x =  -2  ±sqrt( 19)

a) 125 ml of milk

b) 7.5 g of butter

Step-by-step explanation:

Answer: A. Simon needs 125 ml of milk to make 4 pancake.  B. He needs 7 and a half grams of butter to make 12 pancakes

Step-by-step explanation:

A) If we know that 250 ml milk can help make 8 pancakes then we could set up a proportion as to how many milk we need to make 4 pancakes.

  [tex]\frac{250}{8} = \frac{x}{4}[/tex]   Solve by cross  product,

8x = 1000

x = 125  

B) The same with this we could also set up a proportion. We know you need 5 grams of butter when making 8 pancakes.

[tex]\frac{5}{8} = \frac{x}{12}[/tex]    solve by cross product

60 = 8x

x = 7.5

Answer: 4x+3

Step-by-step explanation: 2x+2x=4x

                                             2x1=3

The simplified form of the equation is  4x² + 6x + 2.

Simply put, to simplify is to make something simpler. Simplifying an equation, fraction, or issue in mathematics entails taking something complex and making it simpler. The issue is made simpler by calculations and problem-solving strategies. We can simplify fractions by removing all common elements from the numerator and denominator and putting the fraction in its simplest/lowest form.

Given the equation (2x + 2)(2x + 1)

using property, (a + b)(c + d) = a(c + d) + b(c + d)

(2x + 2)(2x + 1) = 2x(2x +1) + 2(2x + 1)

2x + 2)(2x + 1) = 2x(2x) + 2x(1) + 2(2x) + 2*1

2x + 2)(2x + 1) = 4x² + 2x + 4x + 2

2x + 2)(2x + 1) = 4x² + 6x + 2

Hence the Expand form of the equation is 4x² + 6x + 2.
