Answer:

Step-by-step explanation:

a.square   b.180∘

c.180 degrees    d.rhombus   e.parallelogram

The values of given questions are as follows.

A closed polygon with four sides, four vertices, and four angles is known as a quadrilateral. By joining four non-collinear points, it is formed. A quadrilateral's interior angles are always equal to 360 degrees when added together.

The words "Quadra," which means "four," and "Latus," which means "sides," are the source of the term "quadrilateral." It is not necessary for each of a quadrilateral's four sides to be the same length.

LEVEL 1

Fill in the blanks

a. Square

b. 180⁰

c. Equal and less than 180 degrees.

d. Rhombus

e. Trapezium

f. Rhombus

g. Rectangle

Name the following quadrilaterals

a. A parallelogram in which diagonals are equal, but adjacent sides are not equal is Rectangle.

b. A parallelogram with diagonals unequal, but bisect each other at 90⁰ is a rhombus.

c.  A parallelogram in which adjacent sides are equal and diagonals are equal and bisect each other at 90⁰ is a Square.

LEVEL 2

Q2. one angle of parallelogram  is 80⁰ to find  remaining

we know for parallelogram sum of adjacent angles are equal and opposite angles are equal

let parallelogram  ABCD

∠A = 80⁰ = ∠C

∠B = ∠D

∠A + ∠B = 180

80 + ∠B  = 180

∠B  = 100⁰

∠B = ∠D = 100⁰

Q3. angles of  quadrilateral are in the ratio 1:1:3:4

let each angle be multiple of k

angles are k, k, 3k, 4k

sum of angles is 360⁰

k + k + 3k + 4k = 360

9k = 360

k = 40⁰

angles are

k = 40, k = 40, 3k = 3 x 40 = 120, and 4k = 4 x 40 = 160

40⁰, 40⁰, 120⁰ and 160⁰.

Q4. two angles of quadrilateral is 65⁰ each

let other two angles be x

sum of angles quadrilateral  is 360⁰

65 + 65 + x + x = 360

130 + 2x = 360

2x = 360 - 130

2x = 230

x = 115⁰

other two angles are 115⁰ each.

Q5.  perimeter of Rhombus = 40 cm

p = 4a

where a = side of rhombus

40 = 4a

a = 10 cm

and one diagonal  is 12 cm

diagonals of rhombus bisect each other at 90⁰

Let rhombus be PQRS

and diagonals bisect at O

Since, triangle POQ is a right angled triangle,

PQ²  = OP² + OQ²

OP = 12 / 2 = 6

OQ = SQ/2

PQ = 10

10² = 6² + (SQ/2)²

(SQ/2)² = 100 -36

(SQ/2)² = 64

SQ = 16 cm

length of Diagonal is 16 cm

Hence the solutions of Questions areas follows.

Answer & Step-by-step explanation:

Using the clues given in the image, we can solve the logic problems as follows:

1. From clue 1, we know that Madison is either a programmer, a banker or a chemist.

2. From clue 2, we know that the programmer earns $44,700. Therefore, Alyssa and John cannot be the programmer.

3. From clue 3, we know that the banker earns more than the chemist. Therefore, Madison cannot be the chemist.

4. From clue 4, we know that Alyssa is either a programmer or a writer.

5. From clue 5, we know that the banker earns $53,600. Therefore, Madison is the banker.

6. From clue 6, we know that the chemist earns $42,200. Therefore, Christopher is the chemist.

7. From clue 7, we know that Madison earns more than the writer. Therefore, John cannot be the banker or the chemist.

8. From clue 8, we know that the programmer earns more than the chemist. Therefore, John is not the programmer.

9. From clue 9, we know that the writer does not earn $53,600. Therefore, Alyssa is the programmer and John is the writer.

10. From clue 10, we know that Christopher is either a programmer or a writer. However, we already know that Alyssa is the programmer, so Christopher must be the writer.

11. From clue 11, we know that John is not a banker or a programmer. Therefore, John is the writer.

12. From clue 12, we know that the writer earns more than the programmer. Therefore, John earns $48,100 and Alyssa earns $44,700.

Therefore:

- Madison is the banker and earns $53,600.

- Alyssa is the programmer and earns $44,700.

- Christopher is the writer and earns $53,600.

- John is the chemist and earns $48,100.

Answer:

The correct options are 3, 4, 5, 7, 9, 12, 13.

Step-by-step explanation:

3) The banker earns more than the chemist.

4) Alyssa is not a banker or a chemist.

5) The banker earns $53,600.

7) The banker earns more than the writer.

9) The writer does not earn $53,600.

12) The writer earns more than the programmer.

13) John is not a chemist or banker.

Step-by-step explanation:

ln(∞) = ?

Since infinity is not a number, we should use limits:

x approaches infinity

The limit of the natural logarithm of x when x approaches infinity is infinity:

lim ln(x) = ∞

 x→∞

x approaches minus infinity

The opposite case, the natural logarithm of minus infinity is undefined for real numbers, since the natural logarithm function is undefined for negative numbers:

lim ln(x) is undefined

 x → -∞

So we can summarize

ln(∞) = ∞

Answer:

It costs $4 dollars for 20 ounces of cheese.

Step-by-step explanation:

First we find out how many dollars for 1 ounce of cheese.

3.20 ÷ 16 = 0.2

Next we multiply 0.2 by 20.

20 * 0.2 = 4

So, the answer is 4 dollars.

Hope this helps! :)

You can find price of 1 ounce of cheese, then find cost of 20 ounces of cheese by simply using multiplication.

The cost for 20 ounces of cheese is $4.00

Cost for 20 ounces of cheese

\(16 \: \rm ounce = \$3.20\\\\\\ \text{Dividing by 16 on both sides}\\\\ 1 \rm \: ounce = \dfrac{3.20}{16} = \$0.2\)

Multiplying both sides of above equation by 20, we get:

\(1 \rm \: ounce = \dfrac{3.20}{16} = \$0.2\\ \\ 20 \times 1 \rm \: ounce = 20 \times \$0.2\\ 20 \text{\:ounce of cheese \:}= \$4\)

Thus, the cost for 20 ounces of cheese is $4.00

Answer:

28.57 in²

Step-by-step explanation:

Okay, so the hearts tops area can be figured out with a regular circle area calculation.

A = π r² =

3.14 × 2 × 2=

6.28 × 2 ≈

12.566in ² .

So we could divided by two, but since the two half circles (the top of the hearts) are of the same size, we don't have to. So now we only have to figure out the area for the square. The radius shows us that one side of the square is equal to 4 in. So 4² or 4 × 4 = 16 in².

No all we do is add the areas: 12.566 + 16 = 28.566 in²

Now to round it: 28.566 in² ≈ 28.57 in²

Step-by-step explanation:

When we're solving with scale factors, we either divide or multiply.

If the shape becomes larger, we multiply to get the new length.

If the shape becomes smaller, we divide to get the new length.

We're given:

Because the shape becomes larger, we have to multiply the original side length by the scale factor, 6, to get the new side length.

2.5 x 6 = 15

Therefore, the missing side length is 15 units.

Step-by-step explanation:

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)
