There should be 27 cameras.

The amount of space filled by a flat (2-D) surface or an object's form is known as its area. Draw a square on a sheet of paper with a pencil. A 2-D figure, that is. The term "Area" refers to the area that a form occupies on paper. Now picture that your square is composed of smaller unit squares.

It is 150 feet by 70 feet.

The size of the store will be 150 x 70  feet, or 10,500 square feet. The security cameras now each have 400 square feet.

The area of the shop / each camera's area will determine how many cameras are needed, which is 10500/400.

which is 27

27 cameras are therefore required.

Answer: No

Step-by-step explanation:

The ratio of the lengths of the shortest sides is [tex]\frac{6}{4}=\frac{3}{2}[/tex].

The ratio of the lengths of the longest sides is [tex]\frac{10}{7}[/tex].

Since these ratios are not equal, the triangles are not similar.

The total number of 1 x 1 shaded squares that there will be in the first 21 figures is of:

924.

The number of squares for each figure is given as follows:

(4, 8, 12, 16).

As the difference between consecutive terms of the sequence is constant, this sequence is an arithmetic sequence, with first term of 4 and common difference of 4.

The sum of the first n terms of an arithmetic sequence is given as follows:

[tex]S_n = \frac{n(a_1 + a_n)}{2}[/tex]

The parameters of the equation are given as follows:

Applying the explicit form, the 21st term of the arithmetic sequence in this problem is given as follows:

[tex]a_{21} = 4 + 20 \times 4 = 84[/tex]

Hence the total number of squares in the first 21 figures is obtained as follows:

[tex]S_{21} = 10.5 \times (4 + 84) = 924[/tex]

Answers to both the subparts using mathematical operations are shown:

(A) Rate of the car in miles/min: 0.95 miles/min

(B) Distance traveled in 5 min: 4.8 miles

Calculating a value using operands and a math operator is referred to as performing a mathematical "operation."

The math operator's symbol has predetermined rules that must be applied to the supplied operands or numbers.

PEMDAS stands for Parentheses, Exponents, Multiplication, Division, and Addition Subtraction (from left to right).

So, we know that the rate of the car is 57 miles/hour.

(A) Car rate in miles/min

We know that 1 hour has 60 minutes. Then,

57/60

0.95 miles/min

(B) Distance traveled in 5 min:

The perimeter of the planter 36s

The perimeter of a regular octagon with side s is 8s.Each side of the planter will be 9 inches long.

The length of a shape's outline is its perimeter. You must add the lengths of all four sides of a rectangle or square to determine its perimeter.

The distance around an object is called the perimeter. For instance, the yard of your home is fenced in. The fence's length serves as the perimeter.

The perimeter of a regular octagon with side s is 8s.

Each side of the planter will be 9 inches long.

Through a given point not contained in a given line, there exists exactly one line parallel to the given line.

In Mathematics, parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and they can never meet. In Geometry, two (2) lines are parallel under the following conditions:

m₁ = m₂

Note: m represents the slope.

This ultimately implies that, two (2) lines would be parallel to each other when the slope (m₁) of the first line is equal to the slope (m₂) of the second line.

According to the Parallel postulate, there is always exactly one line that is parallel to a given line in the same plane when a point and a line are given, provided that the point is not on that line.

The number of yellow marbles based on the given ratio will be 78.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.

A ratio is a comparison of two quantities. A proportion is an equality of two ratios.

Suppose, the number of yellow marbles is Y while purple marbles are P.

As per the given,

The ratio Y/P = 13/4

Total Y + P = 102

(13/4)P + P = 102

13P + 4P = 408

17P = 408

P = 24

And, Y = 102 - 24 = 78

Hence , The number of yellow marbles based on the given ratio will     be 78.

What in mathematics is a linear equation?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept. Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

Describe a linear example?

Any function that depicts a straight line on the coordinate plane is said to be linear. For instance, the equation y = 3x – 2 represents a straight line on a coordinate plane, indicating that it is a linear function.

                         This function can be expressed as f(x) = 3x - 2 since y can be replaced with f(x).

The required value of x of a triangle is 27°.

What is a triangle?

A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.

Given, angle measurements of 2x, 4x+6, and x-15

Based on the definition of a triangle, the sum of all angles will be 180 degrees.

So, 2x + 4x+6 + x-15 = 180°

or, 7x - 9 = 180°

or, 7x = 189°

The equation of line which is perpendicular to the given line and passes through the points ( 3, 4) is y = 3x + 5

The slope-intercept form is the way to write a line's equation so that the y-intercept (where the line crosses the vertical y-axis) and slope (steepness) are instantly visible.

The slope intercept form of a straight line equation can be written as :

y = mx + c

Where

m = slope = (change in the y-value) axis's / (change in the value of x in the x axis)

The given line's equation is

y = - x/3 + 5

Slope = - 1/3 as compared to the slope intercept form.

The slope of one line is equal to the negative reciprocal of the slope of the other line if two lines are perpendicular.

As a result, the slope of the line through (3, 4) is 3.

In order to calculate the intercept, we would replace m with 3, x with 3 and y with 4

The equation becomes

4 = 3 × 3 + c

c = -5

putting the value of c and m in the slope intercept form equation

We get

y = 3x - 5

Answer:

A.) y = –3x + 4 and y = –3x – 4

Step-by-step explanation:

The first equation of a system of equations is y = -3x + 4 and the second equation is y = -3x - 4.

We can see that both equations have the same slope of -3 and have different y-intercepts of 4 and -4, respectively.

Because the two lines are parallel, they will never intersect and will overlap each other, resulting in an infinite number of solutions.

Therefore, the system of equations y = –3x + 4 and y = –3x – 4 has infinitely many solutions.

Step-by-step explanation:

Since this is an isosceles triangle, the two angles opposite the congruent sides are also congruent. That means that ∠A and ∠C both equal 73°, you don't even need to solve the equation with y in it. Since all the angles in a triangle add up to 180°, we know that ∠B is equal to [tex]180-(73*2)[/tex], which is 34. So if [tex]34=6x+4[/tex], then you can solve to get [tex]x=5[/tex].

An enclosed 2-D shape called a rectangle has four sides, four corners, and four right angles (90°). A rectangle has equal and parallel opposite sides. A rectangle has two dimensions—length and width—because it is a two-dimensional form.

What is the formula for area of rectangles?

To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle as Area = length x width

Length of the sheep pen =80 ft

bought fencing = 180 ft

One side of rectangular sheep pen is covered with barn which is equaling the  width

perimeter of rectangular sheep pen = 2(length +width)

A linear regression equation that represents this set of data is y = 31x + 799.8.

The calendar year in which the number of new cases would reach 1141 is 2022.

In this scenario, the Year since 2011 (x) would be plotted on the x-axis of the scatterplot while the New cases (y) would be plotted on the x-axis of the scatterplot.

On the Excel sheet, you should right click on any data point on the scatterplot, select format trend line and then tick the box to display an equation for the linear regression (line of best fit) on the graph.

By critically observing the scatterplot (see attachment) which models the relationship given in the table for the Year since 2011 (x) and the New cases (y), an equation for the linear regression is given by:

y = 31x + 799.8

Now, we can estimate the calendar year in which the number of new cases would reach 1141:

1141 = 31x + 799.8

31x = 1141 - 799.8
