5- Perimeter of the new rectangle is 48 cm.

6- Area of the new triangle is 9 cm².

5- A rectangle that has a perimeter of 16 cm has been dilated with a scale factor of 3. To find the perimeter of the new shape, we need to multiply the original perimeter by the scale factor:

16 cm * 3 = 48 cm

So the perimeter of the new shape is 48 cm.

6- A triangle that has an area of 36 squared cm has been dilated with a scale factor of 0.5. To find the area of the new triangle, we need to multiply the original area by the square of the scale factor:

36 cm² * (0.5)²

= 36 cm² * 0.25

= 9 cm²

So the area of the new triangle is 9 cm².

Lines are not perpendicular .

What makes a line parallel?

Perpendicular lines are those that cross at a right angle when two non-vertical lines in the same plane.

                               Vertical and horizontal lines, or the axes of the coordinate plane, are perpendicular to one another. Two parallel lines' slopes are reciprocals with a negative sign.

  2x - 5y = -20

       5y = 2x + 20

In a triangle, the sides have a ratio of 3:7:10. If the perimeter is 210 feet, what is the length of the longest side in feet? (A) * 10.5 (B) 31.5 (C) (D) 105​

[210 : (3 + 7 + 10)] x 10 = 105 ft (your answer)

Step-by-step explanation:

the ratio tells us into how many units the total amount is split and then distributed among the different parts or members of the ratio.

3:7:10 means there are 3+7+10 = 20 units of length.

210 ft is the total of all lengths.

this is now split into these 20 units.

that means one unit of length for the ratio is

210/20 = 10.5 ft

the longest side is clearly the one with 10 units in the ratio.

so, it has

10×10.5 = 105 ft

  (a)  -1/2x +3 = 3x -4

Step-by-step explanation:

Given a graph of two lines, you want to know which equation it is showing the solution for.

The blue line has a slope of -3/6 = -1/2, and a y-intercept of +3, so its slope-intercept equation is ...

  y = -1/2x +3

This expression is seen on the left side of the equal sign for the first choice, and is not seen anywhere else.

By way of confirmation, the red line has slope 3/1 = 3 and a y-intercept that is a negative value less than -2. It is reasonable to say its slope-intercept equation is ...

  y = 3x -4

This expression matches the right side of the equal sign for the first choice.

The solution to the system of these two equations might reasonably be found by equating the expressions for y:

The result is obtained by using the formula for a triangle.

Simply we count the number of grids representing a certain unit.

We have a flag in coordinate system can be seen in the picture.

Each grid represents a foot. Kenna will make five flags.

The flag is a triangle with the base at y-axis.

The base length is 3 ft and the height is 2. The area of the triangle is

Area of a flag = ½ bh

Area of a flag = ½(3)(2)

Area of a flag = 3 ft²

Area of five flags = 5(3 ft)

Area of five flags = 15 ft²

Hence, Kenna will need the material of 3 ft² for one flag and 15 ft² for five flags.

Step-by-step explanation:

Let's start by defining a variable to represent the minimum number of points that Jose must score on the remaining tests:

n = minimum number of points Jose must score on the remaining tests

To get an A for the semester, Jose must score at least 660 points. We know that he has already scored 570 points, so the total number of points he needs to score is:

660 - 570 = 90

Therefore, we can write the following inequality to find the minimum number of points Jose must score on the remaining tests:

n ≥ 90

This means that Jose must score at least 90 points on the remaining tests to get an A for the semester.

The area of the piece of paper left after cutting out the circle is 29.76 in².

Area of a figure:

The amount of unit squares that completely encircle the surface of a closed figure is its area. Area is measured in square units like cm² and m². A shape's area is a two-dimensional measurement. The term “area” refers to the space inside the boundary or perimeter of a closed shape.

You need to first determine the rectangle's area.

8x10=80 in²

determine the circle's overall area.

The diameter is 8 in so you would use 4 as the radius

A=πr²

A=3.14x4²

A=3.14x16

A=50.24 in²

The area of the circle must then be subtracted from the area of the rectangle.

The length of one edge of the cube is 8 cm and the radius of the sphere is 9 cm.

What is the cube root?

The cube root of a number is a value that when multiplied by itself thrice or three times produces the original value. For example, the cube root of 27, denoted as 3√27, is 3, because when we multiply 3 by itself three times we get 3 x 3 x 3 = 27 = 33.

The surface area of a cube is given by the formula:

A = 6 * a^2

where A is the surface area and a is the length of one edge of the cube.

So, in this case:

384 = 6 * a²

Dividing both sides by 6:

64 = a²

Taking the square root of both sides:

a = 8 cm

So the length of one edge of the cube is 8 cm.

The formula for the volume of a sphere is:

V = (4/3) * π * r³

where V is the volume, π is Pi (approximately equal to 3.14), and r is the radius of the sphere.

So, in this case:

729 = (4/3) * π * r³

Dividing both sides by (4/3) * π:

729 / (4/3) * π = r³

Taking the cube root of both sides:

r = pow(729 / (4/3) * π, 1/3) = 9 cm

So the radius of the sphere is 9 cm.

The cube root of 729 is 9.

Hence, the length of one edge of the cube is 8 cm and the radius of the sphere is 9 cm.

In multiple regression, we have 4 assumptions listed and explained below. They are valid.

Following are assumptions for multiple regression model:

1. Linear connection: Each predictor variable and the responder variable have a linear relationship.

Making a scatter plot of each predictor variable and the response variable is the simplest technique to check if this premise is true.

2. Lack of Multicollinearity: There is no significant correlation between any of the predictor variables.

Calculating the VIF value for each predictor variable is the quickest approach to see if this premise is true.

3. Independence: Each observation has its own validity.

The Durbin-Watson test, a formal statistical test that informs us whether or not the residuals (and consequently the observations) exhibit autocorrelation, is the easiest approach to find out if this assumption is true.

4. Homoscedasticity: At every point in the linear model, the residuals' variance is constant.

The simplest technique to check if this premise is true is to plot the standardized residuals against the expected values.

A hexagon, also known as a sexagon, is a six-sided polygon that forms the shape of a cube in geometry. Any basic hexagon has a total internal angle of 720°.

In a regular hexagon, all sides are equal

Which means:

AB= BC

5p + q -5p = 6p-5p

q = p

So, every side of the hexagon is p = q

Which means that AB = BC = CD = DE = EF = FA = p =q

Recall that at the center, each side forms an angle

There are six sides in a hexagon.

Total angle = 360°

6x= 360°

x= 60°.

By the symmetry of regular hexagon, OA = OB

<OAB = <OBA

<AOB = x = 60°

Sum of all angles in a triangle is 180°

We add the values

<OAB = 60°.

<OAB is an equilateral triangle, thus every side is equal

Hence,

a. OA = Q = Q

b. OB = P =Q
