To find the area of a rectangle, we can use the following formula

Therefore, to find the total area we have to multiply his length by his width.

Using the data given in the question, we know that the length is 21 yards and the width is 5 yards. Therefore we find that:

we conclude that the area of the rectangle is 105 yards^2.

Note that the units of the area are square units

Answer:

18 eggs are still good.

Step-by-step explanation:

If 40% was broken then 60% are still good.

30(.6) = 18

Answer: 18 eggs were not broken and considered good.

Step-by-step explanation:  30 x 40% is the amount of eggs that were broken.

30 x 60% would be the amount of eggs that were still good.

This is becuase the total percentage must add up to be 100% between good eggs and broken eggs.

30 x .60 = 18   So 18 eggs were good

30 x .40 = 12, so that was the number of eggs that were broken

You could have done this problem two ways.  Either calculate the broken eggs and subtract from the total.  30-12 = 18, or you could have just calculated the correct amount from figuring the percentage of eggs that were good from the beginning.  

step 1

Find out the scale factor

Remember that

If two figures are similar, then the ratio of their volumes is equal to the scale factor elevated to the cubic

so

Let

s ----> scale factor

s^3=11,000/8,019

s=1.11

step 2

Remember that

If two figures are similar, then the ratio of their surface areas is equal to the scale factor squared

so

s^2=SA/1,134

s=1.11

1.11^2=SA/1,134

SA=(1.11)^2*(1,134)

SA=1,400 yd2

2. The slope of the graph is 1.5

A function is an equation defining the relationship between input and output variables

(A, 2A)

A continuous function is one in which a continuous variation in the input values produces a continuous variation in the output. Therefore, a continuous function does not have discontinuity and it has a defined output within the interval in which it is contagious

A discrete function is one that have input values and output only at specified points, such that the function does not have inputs, and therefore, outputs at certain points.

The points in the scatter plot of the first graph are separate and not linked, such that the function is not contagious between any two x–values, which gives;

The function is a discrete function

The domain, which is the set of possible x–values is; {x| x = -8, -2, 3, 6}

The range is {y|y = 5, 4, -2, 7, }

The line joining the points on the second graph, indicates that the graph has values for all input or x–values

Therefore, the function of the graph is a continuous function

(A3. A) 1. Points on the graph are:

(0, 2), (2, -1)

The slope is given by the equation;

Slope = ∆y ÷ ∆x

Which gives;

2. The given function is; -3•x + 2•y = -6

To find the slope, the function is expressed in the slope and intercept form, y = m•x + c, as follows;

-3•x + 2•y = -6

2•y = 3•x - 6

Therefore;

2•y = 3•x - 6

y = (3•x - 6) = 1.5•x - 3

450 m² of metal are needed to cover the sides of the pyramid.

The correct answer is an option (A)

In this question, a monument is made in the form of a right pyramid with a regular hexagon as a base. each base side is 5 meters and the slant height is 30 meters.

If only the sides (and not the base) of the monument is to be covered by metal, we need to find the amount of metal needed to cover the sides of the pyramid.

Since the base of the pyramid is hexagon, there are 6 triangular sides of the pyramid.

We need to find the area of 6 triangular surfaces.

The base of the triangle b = 5 meters and the height of the triangle is the slant height of the pyramid.

h = 30 meters

So, area of the one triangular surface would be,

A1 = 1/2 × b × h

A1 = 1/2 × 5 × 30

A1 = 5 × 15

A1 = 75 square meters

And the area of the 6 triangular surfaces would be,

A = 6 × A1

A = 6 × 75

A = 450 square meters

Therefore, 450 m² of metal are needed to cover the sides of the pyramid.

A matrix is a collection of numbers that have been put in rows and columns to make a rectangular array. The entries of the matrix are the numbers, which are referred to as its elements. In addition to many areas of mathematics, matrices are widely used in the fields of engineering, physics, economics, and statistics. The representation of rotations and other picture changes has been accomplished using matrices, which have significant uses in computer graphics.

Multiplication of matrices, often known as matrix multiplication, is one of the operations that can be carried out on matrices in linear algebra. If the two matrices given, A and B, are compatible, then matrix A and matrix B can be multiplied. The binary operation of multiplying matrices produces a matrix from two input matrices.

The probability that sunflower will be less than 136 cm tall is 0.9332.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.

From the information, the biologist measures a large sample of sunflowers and creates a probability distribution and the distribution is normal in shape with a mean 112 cm and a standard deviation 16 cm.

It should be noted that the following can be deduced:

Mean = 112

Standard deviation = 16

Sunflower should be less than 136. This will be x < 136.

Therefore, the probability will be;

P(X < 136)

= P(Z < [(number - mean) / standard deviation)]

= P(Z < [136 - 112)/16]

= P(Z < 1.50)

= 0.9332

It should be noted that the probability is gotten by looking at the value of x in the z table.

Answer:

Equation of line is given as y = mx + c, where m is the gradient and c is the y-intercept.

Find gradient of the line first.

Formula of gradient is given as y2-y1 ÷ x2-x1 or y1-y2 ÷ x1-x2, where x and y are the coordinates of the points.

Gradient = (-3-0) ÷ (-2-5) = 3/7

Eqn is y = 3/7x + c

Substitute either one of the coordinates into the equation to find c.

0 = 3/7(5) + c

c = -15/7

Hence, the equation of the line is y = 3/7x - 15/7

1) A prime factorization of a particular number will always give the same prime factors.

2) All the factors in the list when multiplied will give the original number.

3) No, two different numbers cannot have the same prime factorization.

4) The prime factors of 40 are 2 and 5.

1) We anticipate finding factors in prime factorization that can add to themselves to get the original number. The original number can be obtained by multiplying the remaining components together as long as the first factor can divide the quantity without leaving a remnant.

Prime factorization of the number, 15 goes thus;

15/3=5

5/5=1

3*5=15

So, all the factors multiply to give the original number.

2) Numbers that split an original number evenly or precisely are known as its factors. A factor is a whole number that can divide a larger number in two equal halves.

3) The collection of prime numbers that can be multiplied together to produce a given number is known as the prime factorization of that number. Because the same set of numbers must provide the same result when multiplied together, two separate numbers cannot have the same prime factorization.

4) Any number can be represented as a sum of prime numbers using prime factorization. A number with exactly two elements, 1 and the number itself, is said to be a prime number. As an illustration, the prime factorization of 18 is 2 3 3. Here, the two main elements or prime factors of 18 are 2 and 3.

The prime factorization of 40 is :

40 = 2 × 2 × 2 × 5
