Answer:

The correct answer is square and parallelogram

Explanation:

The percentage of people who are satisfied with the car are 60%.

In mathematics →

Given is that in a survey of 2000 people who owned a certain type of​ car, 1200 said they would buy that type of car again.

The percentage of people who are satisfied with the car are -

{x}% = (1200/2000) x 100

{x}% = (12/20) x 100

{x}% = 12 x 5

{x}% = 60

Therefore, the percentage of people who are satisfied with the car are 60%.

Answer:

SSS

Step-by-step explanation:

We have three pairs of corresponding, congruent sides. Therefore, the SSS Postulate can be used to prove the two triangles congruent.

Answer:

C

Step-by-step explanation:

Since we know that squares have all equal sides the area of a square is just a side². So, we would square root 256 in order to find one side. And we know that there are 4 sides of a square so 16+16+16+16= 64. so the answer is C

The value of 'a' for which the system of equations has a unique solution is a = 4/3.

The given system of equations can be written as:

Ax = 2

6x – 2y = 3

To find the value of 'a' for which the system has a unique solution, we can solve the equations for 'x' and 'y' and equate them.

Solving for 'x' in the first equation, we get:

x = 2/a

Solving for 'y' in the second equation, we get:

y = (3 + 6x)/2

Substituting the value of 'x' in the above equation, we get:

y = (3 + 6(2/a))/2

Equating the two equations, we get:

2/a = (3 + 6(2/a))/2

Multiplying both sides of the equation by 'a', we get:

2 = 3a + 6

Subtracting 2 from both sides of the equation, we get:

3a = 4

Dividing both sides of the equation by 3, we get:

a = 4/3

Therefore, the value of 'a' for which the system of equations has a unique solution is a = 4/3.

Answer: 11, 30

Step-by-step explanation:

Given

There were a total of 41 national battlefields and national memorials

Suppose there are [tex]x[/tex] national battlefields

So, national memorials are [tex]3x-3[/tex]

The sum of the two must be 41

[tex]\Rightarrow x+3x-3=41\\\Rightarrow 4x=44\\\Rightarrow x=11[/tex]

So, there are 11 national battlefields and [tex]3\times 11-3=30[/tex] national memorials.

Answer:

y = 8.9

Step-by-step explanation:

Answer:

x = 5   y = -5

Step-by-step explanation:

-7x - 3y = -20

-3y = 7x - 20

y = -7/3x + 20/3

3x + 6(-7/3x + 20/3) = -15

3x - 14x + 40 = -15

-11x = -55

x = 5

-7(5) - 3y = -20

-35 - 3y = -20

-3y = 15

y = -5

The circumference of the circle is 2πr.

The circumference of a circle is the distance around the outside of the circle. It is given by the formula C = 2πr, where C is the circumference, π is the mathematical constant approximately equal to 3.14 and r is the radius of the circle. In other words, the circumference is equal to the diameter times pi.

For the given question,

The formula of the circumference of the circle,

C = 2πr

where r is the radius of the circle.

Answer: A pendulum of length 1m and period 2.01s is placed at the top of Mount Everest having an altitude of 8849m. Calculate the value of 'g' at that point.

The period of this pendulum can be solved using the formula shown in the picture below. T is the period in seconds; L is the length in meters and g is the acceleration due to gravity which is equal to 9.81 m/s²near the equator.

T = 2 × π × (square root of 1.00 m / 9.81 m/s²)

T = 2 * 3.1416 * (square root of 0.101936799)

T = 6.2832 * 0.319275428

T = 2.00 seconds

The period of this pendulum correct to 3 significant figures is 2.00 seconds.

The frequency of this pendulum is solved by the formula f = 1/T

f = 1/2.00 seconds

f = 0.500 hertz

Answer: 9.76 m/s^2

Step-by-step explanation:

The slope intercept form of the equation is

y = -1/4x -11/4

One of the most popular ways to describe a line's equation is in the slope intercept form of a straight line. When the slope of the straight line and the y-intercept are known, the slope intercept formula may be used to get the equation of a line ( the y-coordinate of the point where the line intersects the y-axis). The equation of a line is the equation that each point on the line fulfills.

The slope intercept form is a technique for figuring out a straight line's equation in the coordinate plane. Any point's coordinates on a straight line must fulfill a certain relation, which is known as the equation of a straight line.

Any location that is not on the line will not fulfill the coordinates.

This equation's solution is simple to find. A straight line's slope, or angle of inclination from the x-axis, and the intercept it makes with the y-axis are both necessary to determine the slope intercept form of the line.

The line passes through (1,-3)

slope = -1/4

The equation of the line

y = mx + c

here m is the slope and c is the intercept.

putting the point and slope in the equation

-3 = -1/4 *1 + c

⇒ c = -11/4

So the slope intercept form of the equation is

y = -1/4x -11/4

Step-by-step explanation:

Well I can't really see the equation but I can tell you how to do it.

Parallel slopes are the same slope as the equation.

For example, y = mx + b

The slope of a line parallel to it is m

Perpendicular slopes are the opposite reciprocal as the equation.

For example, y = mx + b

The slope of a line perpendicular to it is[tex]-\frac{1}{m}[/tex]

Answer:

Step-by-step explanation:

parallel lines have the same slopes

perp lines have opposite reciprocal slopes

Answer:

y = 32.5

x = 13

Step-by-step explanation:

opposite angles of the parallelogram are equal to each other.

parallelograms form 360° in total

so 60+ 55 = 115 * 2 (because two angles) = 230

360 - 230 = 130 (divide this by two to get one angle of the parallelogram) so 65°

2y = 65 °. and 5x = 65 °

y = 32.5

x = 13

3x + 5y = 125 .......................(i)

resemble:

9x + 7y = 265 ......................(ii)

Equation (i) multiplied by -3:

-3 (3x + 5y) = 125 * (-3)

-9x - 15y = -375 ...................(iii)

Under (ii) and (iii):

9x + 7y = 265

-9x - 15y = -375

Adding this gives:

-8y = -110

or y = 110/8

or y = 55/4

y = 13.75

From equation (i), we have:

3x + 5y = 125

or 3x + 5(13.75) = 125

or 3x + 68.75 = 125

3x = 125 - 68.75

3x = 56.25

x = 56.25/3

x = 18.75
