9. A parallelogram is a quadrilateral.
True or False?

Answers

Answer 1

Answer:

YES

Step-by-step explanation:

Quadrilateral have 4 sides and their sum  of angles is 360 and parallelogram also have 4 sides and sum of angles is 360

Answer 2

Final answer:

The statement that a parallelogram is a quadrilateral is true. A parallelogram is a type of quadrilateral with parallel opposite sides, and its properties are related to the parallelogram law in vector addition.

Explanation:

A parallelogram is indeed a type of quadrilateral with two pairs of parallel sides. In geometry, quadrilaterals are four-sided polygons, and parallelograms are a specific class within that category. Furthermore, in the context of vector addition, the parallelogram law shows how two vectors can combine to form the sides of a parallelogram. This law is closely related to the triangle law of vector addition as both can depict how vectors combine.

An example of the parallelogram's properties in advanced concepts would be where two objects at rest have world-lines that define a rectangle which may become a parallelogram in a different frame of reference. Additionally, the concept of vectors is also relevant when discussing the diagonals of a rhombus, which is a special type of parallelogram with all sides equal in length. Using vectors and their scalar products, it can be shown that the diagonals of a rhombus are always perpendicular to each other.

The ratio of boys to girls in a class is 3:5. There are 32 students in the class. How many more girls than boys are there?

Answers

Answer:

There are 8 more girls than boys.

Step-by-step explanation:

First, find how many girls and boys are in the class. Add the two parts of the ratio together, 3 and 5 to get 8. Then divide 32 by 8 to get 4. Since the total number of students in the class is 4 times the ratio of boys to girls, multiply both sides of the ratio by 4. You then get 12 boys : 20 girls. You can check this by adding 12 + 20 to get 32. Next, subtract the number of girls from the boys. 20 - 12 = 8. Therefore, there are 8 more girls than boys.

there are 8 girls more than boys

Total ratio = 8

Number of students = 32

Number of boys = 3/8 × 32= 12

Number of girls= 5/ 8 × 32= 20

Girls are more than boys with = (20-12)=8

Therefore there are 8 girls more than boys

-2x+y=-12, 3y- 2x=-12

Answers

Answer:

x = 6

y = 0

Explanation:

−2x+y=−12;3y−2x=−12

Rewrite equations:

−2x+y=−12;−2x+3y=−12

Solve −2x+y=−12 for y

−2x+y=−12

−2x+y+2x=−12+2x(Add 2x to both sides)

y=2x−12

Substitute 2x−12 for y in −2x+3y=−12

−2x+3y=−12

−2x+3(2x−12)=−12

4x−36=−12 (Simplify both sides of the equation)

4x−36+36=−12+36 (Add 36 to both sides)

4x=24

Divide both sides by 4

4x / 4 = 24 / 4

x = 6

Substitute 6 for x in y=2x−12

y=2x−12

y=(2)(6)−12

y=0 (Simplify both sides of the equation)

set equal as -2x+y=3y-2x isolate the variables as -2y = 0. y=0. substitute back in as -2x+0=-12. divide both sides by -2. 6=x.

how do you solve -4(2z+6)-12=4?

Answers

Answer: -8z-40

Step-by-step explanation:

-4(2z+6) = -8z-24

-8z-24-12=-8z-36

-8z-36=4 (you have to move 4 to the other side of the equal sign so 4 becomes -4)

-8z-40

Answer:

z= - 5

Step-by-step explanation:

−4(2z+6)−12=4

Step 1: Simplify both sides of the equation.

−4(2z+6)−12=4(Distribute)

−8z+−24+−12=4

(−8z)+(−24+−12)=4(Combine Like Terms)

−8z−36=4

Step 2: Add 36 to both sides.

−8z−36=4

−8z=40

Step 3: Divide both sides by -8.

Which expressions are equivalent to 4^-3 / 4^-1

Choose two answers

A. 4^1 / 4^3

B. 1/4^2

c. 4^3 x 4^1

d. (4^-1)^-3

Answers

Answer:

The answer is A and B

Step-by-step explanation:

Because 4 to the power of -3 divided by 4 to the power of -1 switched (Like when there is a negative exponent you move the number or variable to the other side of the fraction) and scince both have a negative number you switch both. and 1-3 is -2 so you switch it to the bottem and put a 1 at the top.

                                         ^^Hope this helps!

Final answer:

The expressions equivalent to 4^-3 / 4^-1 are 1/4^2 and (4^-1)^-3.

Explanation:

In the subject of mathematics, the given expression is 4^-3 / 4^-1. To simplify this expression, you need to understand two rules of exponents:

The rule a^-n = 1/a^n, which says that a negative exponent indicates the reciprocal of the positive exponent, andWhen you divide numbers with the same base, you should subtract the exponents.

Applying these two rules, 4^-3 / 4^-1 = 4^-3 * 4^1 = 4^(1 - 3) = 1/4^2.

Another way to simplify the expression is to use the rules of exponents to rewrite each part independently. 4^-3 = 1/4^3 and 4^-1 = 1/4. Therefore, 4^-3 / 4^-1 = (1/4^3) / (1/4) = 4, which is equivalent to (4^-1)^-3.

Therefore, the equivalent expressions are (B) 1/4^2 and (D) (4^-1)^-3.

A plane was traveling from Florida to Canada. It flew 5 hours and went 1895km what was it’s velocity?

Answers

The velocity of plane is 379 kilometer per hour

Solution:

Given that, plane was traveling from Florida to Canada

It flew 5 hours and went 1895 km

To find: Velcoity

The velocity can be found by dividing the distance traveled by time taken

[tex]velocity = \frac{distance}{time}[/tex]

Here in this sum,

distance = 1895 km

time = 5 hours

Substituting the values in formula,

[tex]velocity = \frac{1895}{5}\\\\velocity = 379[/tex]

Thus velocity of plane is 379 kilometer per hour

What is area of this shape

Answers

Answer:

132 ft squared

Step-by-step explanation:

One way is to divide the shape into a rectangle and a triangle, by drawing a vertical line.

This gives a rectangle that is 9 by 11, so has area 99.

The triangle has a base of 11 and height of 15 - 9 = 6.

So the area of the triangle = 1/2 x b x h = 1/2 x 11 x 6 = 33

So the total area is 99 + 33 = 132.

write the expression for twice a number y increased by 4

Answers

2y + 4 is the expression for twice a number y increased by 4

Solution:

Given statement is:

Twice a number y increased by 4

Let us convert the given statement into algebraic expression

Let the number be "y"

In the given statement,

Twice a number means "y" is multiplied by 2

"Twice a number" is translated as 2y

Also,

"Increased by" means added, Which means 2y is added to 4

Therefore,

Twice a number y increased by 4 is translated as 2y + 4

Thus the final equation becomes: 2y + 4

What is the equation of the line through (2,-4) and (0,4)

Answers

the equation of the line is y=4x+4
Before we solve this question, recall the equation of a line, 'y = mx + b' In this, 'm' represents slope and 'b' represents y-intercept.

Let's start with the slope first. In order to solve for the slope, we have to use the equation (y2 - y1)/(x2 - x1)

Input the values:
m = (4 - (-4))/(0 - 2)
m = 8/-2
m = -4

Now we have the first bit of the equation:
y = -4x + b

In y-intercepts, the coordinates always have x as 0. Knowing this, we know that (0, 4) is the y-intercept of the line.

Input this into the equation:
y = -4x + 4

Measure of one of the vertical angle is 156°

Solution:

The measure of angles given are (x + 104)° and 3x°.

The given angles are vertical in order.

If two lines meet at a point, then the angle formed in vertical positions are equal.

That is vertically opposite angles are equal.

⇒ 3x° = (x + 104)°

⇒ 3x° = x° + 104°

Subtract x° on both sides of the equation to equal the expression,

⇒ 3x° – x° = x° + 104° – x°

⇒ 2x° – x° = 104°

⇒ 2x° = 104°

Divide both sides of the expression by 2, we get

x° = 52°

Substitute x° = 52° in one of the vertical angle.

3x° = 3 × 52° = 156° (or)

x° + 104° = 52°+ 104° = 156°

Hence the measure of one of the vertical angle is 156°.

What is the equation of the line that is parallel to y = –4x + 3 and has a y-intercept of -1/3

Answers

The equation of the line that is parallel to given line is 12x + 3y = -1

Solution:

Given that, the line that is parallel to y = –4x + 3 and has a y-intercept of -1/3

Given equation of line is:

y = -4x + 3

Let us first find the slope of line

The equation of line in slope intercept form is given as:

y = mx + c ------- eqn 1

Where, "m" is the slope and "c" is the y intercept

On comparing the above slope intercept form with given equation of line, we get m = -4

Thus the slope of line with equation y = -4x + 3 is -4

We have to find the slope of line that is parallel to above line

We know that slopes of parallel lines are equal

Therefore, slope of line passing parallel to given line is -4

Now find the equation of line

[tex]\text{Substitute } m = -4 \text{ and } c = \frac{-1}{3} \text{ in eqn 1 }[/tex]

[tex]y = -4x -\frac{1}{3}\\\\3y = -12x -1\\\\12x + 3y = -1[/tex]

Thus the equation of line is found
