The increase in square feet when the garden is enlarged is 400 square feet.

The first step is to determine the perimeter of the fence:

Perimeter = 2( length + width)

2 (60 + 20)

= 160 feet

When the shape of the garden is changed to a square, the perimeter of the square and the rectangle has to be the same.

Length of side of the square = 160 / 4 = 40 feet

Area of the square = 40 x 40 = 1600 square feet

Area of the garden = 60 x 20 - 1200 square feet

Difference = 1600 - 1200 = 400 square feet

Answer:

This cannot be explained properly by me, but the answer is 4 3/4*1 1/3 divided by (7 1/2-1 1/6). I just did a lot of trial and error

Step-by-step explanation:

The mathematical operations used [tex](4.75/7.50) * 1.17 * 1.34[/tex].

An operation exists as a mathematical action. Addition, subtraction, multiplication, division, and calculating the root exist all instances of a mathematical operation.

Given: 4 3/4 _ 7 1/2 _ 1 1/6 _ 1 1/3 = 1 or

4 3/4 _ 7 1/2 _ 1 1/6 _ 1 1/3 = 1

Convert mixed fraction into a proper fraction we have

[tex](19/4) * (15/2) * (7/6) * (4/3) = 1[/tex]

Now convert the proper form of the fraction into a decimal

[tex]$4.75 * 7.50 * 1.16 * 1.34[/tex]

Inserting operation signs, then we get

[tex]= (4.75/7.50) * 1.17 * 1.34[/tex]

= 0.99294

= 1 (approximately)

Therefore, the correct answer is [tex](4.75/7.50) * 1.17 * 1.34[/tex].

The expression of the volume of the cone that is π/4 of the volume of the pyramid, is expressed as: [tex]\mathbf{\frac{\pi}{4} (\frac{4r^2h}{3} )}[/tex].

Volume of a pyramid = 1/3(length)(width)(height)

Find the volume of the pyramid in the image given:

Volume of the pyramid = 1/3(2r)(2r)(h)

Volume of the pyramid = 4r²h/3

We are given that the volume of the cone is π/4 of the volume of the pyramid.

Therefore, the expression that represents the volume of the cone would be: [tex]\mathbf{\frac{\pi}{4} (\frac{4r^2h}{3} )}[/tex]

The focal length of the lens is 40cm.

The distance between the center of a lens or curved mirror and its focus.

A plane convex lens is made of glass ( n = 1. 5) with one flat surface and the other having a radius of 20 cm.

The focal length of the lens is given by the following formula;

[tex]\rm \dfrac{1}{f}=(n-1) \left ( \dfrac{1}{r_1}-\dfrac{1}{r_2} \right)\\\\Where; \ r_1 =\infty , \ r_2=20, \ and \ n = 1.5[/tex]

Substitute all the values in the formula;

[tex]\rm \dfrac{1}{f}=(n-1) \left ( \dfrac{1}{r_1}-\dfrac{1}{r_2} \right)\\\\\rm \dfrac{1}{f}=(1.5-1) \left ( \dfrac{1}{\infty}-\dfrac{1}{20} \right)\\\\ \rm \dfrac{1}{f}=(0.5) \left ( 0-\dfrac{1}{20} \right)\\\\ \dfrac{1}{f} = \dfrac{-0.5}{20}\\\\\dfrac{1}{f}=-0.025\\\\f = \dfrac{-1}{0.025}\\\\f=-40[/tex]

Step-by-step explanation:

Y-intercept 5

Answer:

y- intercept = 5

Step-by-step explanation:

to find the y- intercept let x = 0 in the equation and solve for y

this relies on the fact that when the line crosses the y- axis the x- coordinate is zero, then

0 - 2y = - 10 , that is

- 2y = - 10 ( divide both sides by - 2 )

y = 5

then y- intercept = 5

Answer:

we know that sum of two complementary angles always equals to 90°

now ∠ABC and ∠CBD are complementary which means ∠ABC + ∠CBD = 90

∠ABC = 35° given

so ∠CBD = 90° - ∠ABC = 90° - 35° = 55°

therefore hence proved ∠CBD = 55°

10 is the mean of the number that is missing.

A property of an assortment of data that represents an average is called the mean. Depending on the nature of the information as well as the kind of average you require, one can compute the mean theoretically employing any of the several ways. Scheming the data distribution constantly allows one to visually determine the mean as well.

Let the missing number be x.

The sum of all the numbers will be

= 11 + 20 + 3 + 1 + x

= 35 + x

The total number is 5.

The mean is given to be 9.

The mean will be

9 = (35 + x) / 5

9 * 5 = 35 + x

45 = 35 + x
