Parallelogram ABCD is a rhombus. Side BC = 5cm and segment AO = 3.8cm
What is the area of ABCD?
What is the length of diagonal BD?

Answers

Answer 1

The area of the rhombus ABCD is 24.7 cm².

The length of diagonal BD is 6.5 cm.

What is the area of a rhombus?

A rhombus have equal four sides and the diagonals of the rhombus divides it into four equal right triangles. The area of the rhombus is the sum of individual areas of the four right triangles.

The hypotenuse side of the right triangle = side of the rhombus = BC = 5 cm

One of the legs of the right triangle = AO = OC = 3.8 cmLet the second leg of the right triangle = OB = OD =  x

The second leg of the right triangle is calculated as follows;

[tex]x^2 + 3.8^2 = 5^2\\\\ x^2 = 5^2 - 3.8^2 \\\\ x^2 = 10.56\\\\ x = \sqrt{10.56} \\\\ x = 3.25 \ cm[/tex]

The area of one right triangle of the rhombus is calculated as follows;

[tex]A = \frac{1}{2} (3.8)(3.25)[/tex]

The area of the rhombus ABCD is calculated as follows;

[tex]A = 4 \times \frac{1}{2} (3.8)(3.25)\\\\ A = 24.7 \ cm^2[/tex]

The length of diagonal BD is calculated as follows;

[tex]BD = OB \ + \ OD\\\\ BD = x \ + \ x\\\\ BD = 3.25 \ cm \ + \ 3.25 \ cm\\\\ BD = 6.5 \ cm[/tex]

Solve for x
simple geometry

Answers

The answer is 29

when we see angles like that we will use a property of a parallelogram

which means

2x-10 angle plus 4x+16 angle equal to 180 degrees

let's find out

(2x-10)+(4x+16)=180

6x+6=180

6x=174

x=29

Have a great day

Answer:

From the above attachment we can conclude that,

[tex](2x - 10)° + (4x + 16)° = 180° \\ 2x - 10 + 4x + 16 = 180 \\ 2x + 4x - 10 + 16 = 180 \\ 6x + 6 = 180 \\ 6x = 180 - 6 \\ 6x = 174 \\x = \frac{174}{6} \\ \boxed{x = 29}[/tex]

Therefore, the value of x is 29

x = 29 is the right answer.

Point upper D left parenthesis negative 3 comma 5 right parenthesis. is a vertex of triangle DEF. After a rotation of the triangle about the origin, upper D prime is located at left parenthesis 3 comma negative 5 right parenthesis. Which of the following was the rotation of the triangle?

Answers

The rotation that the triangle DEF underwent is defined as follows:

180º around the origin.

Rotation

A rotation is one example of transformation that a function can undergo, along with transformation, compression, stretching, dilation or reflection.

A rotation changes the inclination of the figure, and the rules for each rotation are given as follows:

90° clockwise rotation: (x,y) -> (y,-x)90° counterclockwise rotation: (x,y) -> (-y,x)180° clockwise and counterclockwise rotation: (x, y) -> (-x,-y)270° clockwise rotation: (x,y) -> (-y,x)270° counterclockwise rotation: (x,y) -> (y,-x)

In this problem, the coordinates are given as follows:

Original: (-3,5).Image: (3,-5).

Hence the rule is:

(x,y) -> (-x, -y).

Meaning that a rotation of 180º around the origin was done.

3/7*336=144

Unit rate is the quantity of an amount of something at a rate of one of another quantity.

If out of 28 students, 12 students packed their lunch.

The number of students who packed their lunch out of 336 students is 144 students.

What is a unit rate?

It is the quantity of an amount of something at a rate of one of another quantity.

Example:

3 miles in 3 hours.

1 mile in one hour.

We have,

In a class of 28 students, 12 students packed their lunch.

We can write this as:

28 students = 12 students packed lunch ______(1)

We have to make 28 students into 336 students.

This can be done by multiplying 12 on both sides of the equation (1)

Multiply 12 on both sides.

12 x 28 students = 12 x 12 students packed lunch

336 students = 144 students packed lunch

Thus,

The number of students who packed their lunch out of 336 students is 144 students.

How much more money do the employees from Hideaway Pizza make at
the end of the month than the employees at Red & Blue's? Round your
answer to the nearest hundredth.

Answers

Supposing linear functions for both cases, it is found that employees at Hideaway pizza make $250 more at the end of the month.

--------------------

The salary, in dollars, for x days of work at Hideaway pizza is of:

[tex]S_h(x) = 300 + 40x[/tex]

At Red & Blue's, it is of:

[tex]S_r(x) = 500 + 25x[/tex]

A month is 30 days, so, the salaries are:

[tex]S_h(30) = 300 + 40(30) = 300 + 1200 = 1500[/tex]

[tex]S_r = 500 + 25(30) = 500 + 750 = 1250[/tex]

1500 - 1250 = 250, thus:

Employees at Hideaway Pizza make $250 more at the end of the month.

Answers

Answer:

60

Step-by-step explanation:

if 6 questions is 20 percent, that means every 3 questions should be 10 percent. 60÷3=20

Answer:

The Answer is 30 questions in total.

Step-by-step explanation:

1. The first thing you would want to do is to break down this question.

For every 6 questions, this is 20% of the test done.

2. You now would want to divide 100% (the full amount on the test) by 20%.

100%/20% = 5

3. Now, multiply both to get your answer.

6·5= 30

20%x5= 100%.

Therefore, the total amount of questions on the test is 30 questions.

Calculation of an equation:

Since dad gave him 75 coins. each month he will add 20 coins.

Here we assume a number of months be x
