Answer:

ABCD is not a parallelogram

Step-by-step explanation:

Use the distance formula to determine whether ABCD below is a parallelogram. A(-3,2) B(-3,3) C (5,-3) D (-1.-5)

We have to find the length of the sides of the parallelogram using the formula below

= √(x2 - x1)² + (y2 - y1)² when given vertices (x1, y1) and (x2, y2)

For side AB

A(-3,2) B(-3,3)

= √(-3 -(-3))² + (3 -2)²

= √0² + 1²

= √1

= 1 unit

For side BC

B(-3,3) C (5,-3)

= √(5 -(-3))² + (-3 -3)²

= √8² + -6²

= √64 + 36

= √100

= 10 units

For side CD

C (5,-3) D (-1.-5)

= √(-1 - 5)² + (-5 - (-3))²

= √-6² + -2²

= √36 + 4

= √40 units

For sides AD

A(-3,2) D (-1.-5)

= √(-1 - (-3))² + (-5 -2)²

= √(2² + -7²)

= √(4 + 49)

= √53 units

A parallelogram is a quadrilateral with it's opposite sides equal

From the above calculation

Side AB ≠ CD

BC ≠ AD

Therefore, ABCD is not a parallelogram

Answer:

1 = 130

2 = 50

3 = 130

Step-by-step explanation:

Since we already know that one angle is 50 degrees, this also tells us that angle two is congruent to it because it is opposite to it. Now the two other adjacent angles, basically just do 180-50 to get 130.

Given:

The two numbers are 6788678 and 1234567 .

To find:

The numbers that must be taken away from the sum of 6788678 and 1234567 to make it equal to the difference of the given numbers.

Solution:

Let x be the required number.

Sum of given numbers is:

[tex]6788678+1234567=8023245[/tex]

Difference of the given number is:

[tex]6788678-1234567=5554111[/tex]

The number x is taken away from the sum of 6788678 and 1234567 to make it equal to the difference of the given numbers.

[tex]8023245-x=5554111[/tex]

[tex]8023245-5554111=x[/tex]

[tex]2469134=x[/tex]

Therefore, the required unknown number is 2469134.

Though these segments aren't marked congruent in the diagram, the two lines inside the circle making up the bases of the triangles are congruent as all radii are congruent. So the triangles are congruent by SAS.

Answer: 3

Step-by-step explanation:

The student answered 21 questions correctly on a test.

In mathematics, Multiplication operations perform Multiplying values on either side of the operator.

For example 4×2 = 8

Since the student made an 85% on a test with 25 questions.

To determine the number of questions the student answered correctly, we need to multiply the number of questions by the percentage of questions answered correctly, which is 85%.

= 25 questions × 0.85

Apply the multiplication operation, and we get

= 21.25

Rounding to the nearest whole number,

= 21 questions

Thus, the student answered 21 questions correctly.

Answer:

135degrees

Step-by-step explanation:

Find the diagram attached.

Note that in a cyclic quadrilateral, the sum of the opposite side of the quadrilateral is 180degrres.

According to the diagram shown:

<D+<I = 180

<D+45 = 180

Subtract 45 from both sides

<D+45-45 = 180-45

<D = 180-45

<D= 135°

Hence the measure of <D is 135degrees

Answer: The CORRECT answer is

a=1, b=8, c=6

Step-by-step explanation:

Took the quiz

The values that can be use for a, b and c in the equation 2x² + 7x − 5 = 0 are a = 1, b = 8, c = 6

The quadratic equation formula is represented as follows:

ax² + bx + c

where

Therefore, lets model the quadratic equation x² + 8x + 6 = 0 to ax² + bx + c

Hence,

a = 1

b = 8

c = 6

Answer:

To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results

Answer:

Find the area of each triangle and then add it up. As you are aware, to find the area of a triangle the equation is B times Height divided by 2.  And to make it easier do the top left triangle and the top right triangle, add them together and then divide that by 2.

Step-by-step explanation:

3 time 5 equals 15 divided by 2 equals 7.5

5 times 8 equals 40 divided by 2 equals 20

7.5 plus 20 equals 27.5

27.5 times 2 equals 55

therefor your answer should be 55m

answer:number of cupcakes sold is 13  Number of cookies sold is 27  

Step-by-step explanation:

Let x represent the number of cupcakes that Victor sold.  Let y represent the number of cookies that Jane sold.  Each cupcake sold for $2.25 and each cookie sold for $0.50. At the end of the day,  This mean Victor had 2.25x 0.5y = 42.75 - - - - - - - - - -1she sold 40 cupcakes and cookies combined, it means thatx y = 40Substituting x = 40 - y into equation 1, it becomes2.25(40 - y) 0.5y = 42.7590 - 2.25y 0.5y = 42.75- 2.25y 0.5y = 42.75 - 90- 1.75y = - 47.25y = - 47.35/-1.75y = 27x = 40 - yx = 40-27 = 13

An equation is formed when two equal expressions. The number of cupcakes that Victor sold is 35, while the number of cookies that Victor sold is 33.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the number of cupcakes sold be represented by x, while the number of cookies sold is represented by y.

Now, the total number of cupcakes and cookies sold combined is equal to 68. Therefore, the equation can be written as

x + y = 68

x = 68 - y

Also, Each cupcake sold for $2.25 and each cookie sold for $0.50. And the total sale that Victor made is of $95.25. Therefore, the equation can be written as,

2.25x + 0.50y = 95.25

2.25(68 - y) + 0.5y = 95.25

153 - 2.25y + 0.5y = 95.25

-2.25y + 0.5y = 95.25 - 153

1.75y = 57.75

y = 33

Now, substitute the value of x in the first equation.

x + y = 68

x + 33 = 68

x = 35

Hence, the number of cupcakes that Victor sold is 35, while the number of cookies that Victor sold is 33.

Answer:

9x-4 / (x²-4)

Step-by-step explanation:

common denominator is 'x²-4' which is (x-2)(x+2)

the term '7x' already has that denominator but 2/x+2 becomes 2(x-2)/(x²-4)

now you can add 7x to 2(x-2) which is 7x + 2x - 4 or 9x-4 and

your denominator remains as 'x²-4'

Answer:

Step-by-step explanation:

mean is calculated as

mean = [tex]\frac{sum}{count}[/tex]

Given the mean of 12 numbers is 20 , then

[tex]\frac{sum}{12}[/tex] = 20 ( multiply both sides by 12 )

sum = 240

Given the mean of 8 numbers is 25 , then

[tex]\frac{sum}{8}[/tex] = 25 ( multiply both sides by 8 )

sum = 200

Total sum of the 20 numbers = 240 + 200 = 440, then mean of 20 numbers is

mean = [tex]\frac{440}{20}[/tex] = 22

Answer:

0.8 hour

Step-by-step explanation:

Given data

Coordinate

P(50, -30)

Say Wharehouse N has a coordinate of N(0,0)

We can find the distance between two coordinate by

d=√((x_2-x_1)²+(y_2-y_1)²)

d=√((50-0)²+(-30-0)²)

d=√50²+(-30)²)

d=√2500-900

d=√1600

d= 40 miles

We know that

Speed= distance/time

50= 40/t

t= 40/50

t= 0.8 hour

Answer:

4 students

Step-by-step explanation:

what we know: 12 students, 2/3 are wearing blue, 1/6 are wearing red

first you have to make the fractions have the same denominator(2/3=4/6)

theres also 1/6 that are not wearing blue or red (1/6+4/6=5/6, 6/6-5/6=1/6)

so that makes it 2/6 of the students not wearing blue(1/6+1/6=2/6)

simplify(2/6=1/3)

1/3 of 12 is 4 (12÷3=4)

the equations are in parentheses and bolded, italicized, underlined.
