A,find the length of the side of original garden B,What is the width of the new garden?
C,what is the length of the new garden?
D,find the area of the new garden?​

Answers

Answer 1

A. The length of the side of original garden is 4 m

B. The width of the new garden is 5m

C. The length of the new garden is 7m

D. The area of the new garden is 35 m²

Let the side of the garden = x m.

area = x² m²

From the question, we have

The new length is (x+3) m and the new width is (x+1) m.

Then the new area = (x+3)(x+1) m².

(x+3)(x+1)=x²+19

⇒ x²+3x+x+3=x²+19

⇒ 4x+3=19

⇒ 4x=19-3

⇒ 4x=16

x = 4 m

The length of the side of original garden is 4 m

new length = (x+3) m = (4+3)m = 7 m

new width = (x+1) = (4+1) = 5 m

new area = (x+3)(x+1) m² = 7*5 = 35 m²

Multiplication:

Finding the product of two or more numbers in mathematics is done by multiplying the numbers. It is one of the fundamental operations in mathematics that we perform on a daily basis. Multiplication tables are the main use that is obvious. In mathematics, the repeated addition of one number in relation to another is represented by the multiplication of two numbers. These figures can be fractions, integers, whole numbers, natural numbers, etc. When m is multiplied by n, either m is added to itself 'n' times or the other way around.

−||6c−16b||+1

Answers

The value of the expression − || 6c − 16b || + 1 if a = −12, b = 34, and c = −23 is - 681.

We that the modulus always gives a positive quantity.

For example: || -5 || = 5, etc.

We are given;

a = −12, b = 34, and c = −23.

We need to find − || 6c − 16b || + 1.

The solution of an algebraic expression is obtained by substituting the given values in the expression.

Substitute the given value in the above expression, we will get;

− || 6c − 16b || + 1

= − || 6 * -23 − 16 * 34 || + 1

=  − || - 138 − 544 || + 1

= − || - 682 || + 1

= − 682 + 1

= - 681

So, the value of − || 6c − 16b || + 1 is - 681.

Thus, the value of the expression − || 6c − 16b || + 1 if a = −12, b = 34, and c = −23 is - 681.

Answers

If you pick 25 fruits at random, then 15% of the time, their mean weight will be greater than 665 grams.


What is mean?

In statistics, mean is the ratio of sum of all the observations and total number of observations in a data set.

How to calculate their mean weight will be greater than how many grams?
Given that from the question

Mean = 641 grams

standard deviation 24 grams

If you pick 25 fruits at random, then 15% of the time, their mean weight will be greater than how many grams?

The formula for the calculating the x value in the normal distribution is,

x = μ + zσ

The level of significance is = 15% = 0.15

Therefore,

z = (=normsinv (1 - α))

= (=normsinv (1-0.15))

= (=normsinv(0.85))
= 1.036

The critical value of z is 1.036

z = 1.036

(x - μ) / σ = 1.036

x = μ + 1.036σ

= 641 + 1.036*23

= 641 + 23.828

= 664.828

Dilation on a image

Dilation in a image means multiply the coordinates of each vertex of the figure by the scale factors.

Given,

Here we have the triangle in the given figure.

Now, we have to find the dilation of the figure with the scale factor of 3/4.

Here from the original figure graph, the vertices are obtained as follows:

S(-8,-4), T(4, -4) and U(4,8)

Now we have to use the dilation scale factor of 3/4,

Which means that the coordinates are multiplied by 3/4,

Then the new coordinates of the resulting image are given as follows:

S(-8, -4) => ((-8 x 3/4), (-4,3/4)) => S'(-6, -3)

T(4, -4) => ((4 x 3/4), (-4,3/4)) => T'(3, -3)

U(8, 4) => ((8 x 3/4), (4,3/4)) => U'(6, 3)

Now, we have to plot these new coordinates on the graph, then we get,

Answers

a) Karmila have 5 pieces of ribbon each 3/4 m long

b) the length of ribbon left over​ =   1 m

A roll of ribbon was 8m long.

Karmila cut 6 pieces of ribbon each length 2/3

Total length of 6 pieces of ribbon having length 2/3 would be,

6 * (2/3) = 4 m

This means, after cutting 6 pieces of ribbon, the length of the remaining ribbon = 4 m

Then we need to cut the remaining ribbon into some pieces each of length 3/4

Let t be the number of pieces.

So, we get an equation

(3/4) * t = 4

t = 4 * (4/3)

t = 16/3

t = 5 1/3

t ≈ 5

Answers

The volume of the largest right cylinder that fits in a sphere of radius 4 units is 143 m².

Let the diameter of the cylinder be “d" and the height of the cylinder be “h".

Given radius of the sphere = r = 4m

Diameter of the sphere = d = 2r = 2×4 = 08 m

As the cylinder is inscribed in the sphere

Therefore, the diameter of the cylinder be “d" is equal to the height of the cylinder be “h".

i.e, d = h

By Pythagoras Theorem, In triangle ABC

AB²+BC²=AC²

Or, d²+h² = (8)²

Or, h²+h² = 64

Or, 2h² = 64

Or, h² = 64/2

Or, h = √32

And d =√32

Or, r = d/2

       = √32/2 =16/√32

Or, r = 16/√32

Volume of the cylinder = πr²h

                                       =22/7 × (16/√32 )² × √32

                                       = 22/ 7 × 8 ×√32

                                       = 142.229

First choose two points

The first point = (3, 3/5)

The slope of the line is the change in y coordinate with respect to the change in x coordinate of the line

The slope of the line = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Where [tex](x_1,y_1)[/tex] is the coordinates of the first point
