Answer:

A edge 2021

Step-by-step explanation:

Point A Represents (3,-5π/3).

The distance from a point to the origin (r) and the angle this line makes with a fixed line (Θ) are the two coordinates that specify where a point is located in a plane.

The radius of circle is 3 units.

The angle in the polar coordinate measured clockwise is considered negative and measured anticlockwise as positive.

In order to get the position of the angle from the x-axis the angle should be added by 2π as

Θ = 2π-5π/3

Θ = π/3

The angle is calculated clockwise.

From the diagram point, A represents the angle  π/3.

Thus, the Point A Represents (3,-5π/3).

Answer:

Step-by-step explanation:

the bat is 12. the pumpkin is 5. and the weird looking thing is 14

14 plus 14 plus 12 is 40

12 minus 5 is 7

5 plus 14 is 19

14 minus 5 plus 12 is 21

Answer:

  21

Step-by-step explanation:

Green bat:   x

Purple bat:   y

  Pumpkin:   z

Given:

  2x + y = 40

  y - z = 7                ===>      y = 7 + z

  z + x = 19             ===>       z = 19 - x

Substitution to find green bat x:

  2x + y = 40

  2x + (7 + z) = 40

  2x + 7 + z = 40

  2x + 7 + (19 - x) = 40

  2x + 7 + 19 - x = 40

  x + 26 = 40

  green bat:  x = 14

Substitution to find pumpkin z:

  z + x = 19

  z + (14) = 19

  z + 14 = 19

  pumpkin:  z = 5

Substitution to find purple bat y:

  y - z = 7

  y - (5) = 7

  y - 5 = 7

  purple bat:  y = 12

Solve for x - z + y:

  14 - 5 + 12 = 21

Answer:

radius = 9

Step-by-step explanation:

The equation of the circle centred at the origin is

x² + y² = r² ( where r is the radius )

Given

x² + y² = 81, then

r² = 81 ( take the square root of both sides )

r = [tex]\sqrt{81}[/tex] = 9

Answer:

There would be 210 calories in a 3/4 cup serving.

Step-by-step explanation:

1/2 of 140 = 70

70 = 1/4

70 x 3 = 210 = 3/4

I hope this helped you! If it did, please consider pressing thanks, rating my answer, and marking as Brainliest. It would be a big help! Have a great day! :)

Based on the number of calories in 1/2 cups, the number of calories in 3/4 cups is 210 calories.

You can use direct proportion to solve for this by assuming that the calories in 3/4 cups is x:

1 / 2          :         140 calories

3 / 4          :        x

Cross multiplying would give:

1/2x = 105

x = 105 ÷ 1/2

x = 210 calories

In conclusion, there would be 210 calories in 3/4 cups.

Answer:

The better deal is the 12 pack because the unit price is $0.37 which is lower than the unit price of the 18 pack that is $0.80.

Step-by-step explanation:

To find which is the better deal, you have to determine which one offers a lower unit price by dividing the price of each package by the number of balls in the pack:

$4.47/12=$0.37

$14.46/18=$0.80

According to this, the answer is that the better deal is the 12 pack because the unit price is $0.37 which is lower than the unit price of the 18 pack that is $0.80.

Answer:

C.

Step-by-step explanation:

A has 8 lines of symmetry, because they're all the same.

B has 4 lines of symmtery because those are all the same

C has only 2 because the vertical lines are symmetrical to each other, but not to the horizontal lines

D has 10 symmetrical lines because they're all the same

Answer:

The slope equation says that the slope of a line is found by determining the amount of rise of the line between any two points divided by the amount of run of the line between the same two points. In other words, Pick two points on the line and determine their coordinates.

Answer:

Step-by-step explanation:

Let the width of the margins as x.

So, we subtract 'x' width on each side of the paper.

So, length = 26-x-x= 26-2 x

Width = 27-x-x=27-2 x

Now, it is given printed area is 360

We can set up equation using length x width = Area

(26-2 x)(27-2 x) = 360

Multiply the left side using FOIL method,

702 -52  x-54 x+4 x^2 =360

Combine like terms

702-106x+4x^2=360

Subtract both sides 360

4x^2-106x+342 =0

Let's divide both sides by 2 to simplify

2x^2 -53x+171=0

Let's use quadratic formula to solve.

Answer:

D. 29

Step-by-step explanation:

First, let's make things a bit easier for ourselves and convert mixed numbers to improper fractions

[tex]-\frac{10}{3}* -\frac{87}{10}[/tex]

Next, we check for numbers that can cancel out. In this case, we have 10.

[tex]-\frac{1}{3}*-\frac{87}{1}[/tex]

Because negatives cancel out, we get

[tex]\frac{87}{3}[/tex]

when we multiply.

Fractions just mean division, so we divide 87 by 3 and get

Both B and C

B)

2/5 = 0.4 (which terminate as decimals)

Similarly

C)

-1/4 = -0.25 (also terminates)

But A and D do not terminate

As for A) 1/3= 0.33333333..........

and for D) 7/9= 0.777777777......

In both cases the decimals are a never ending sequence or in other words does not terminate at all. They are irrational numbers.

Answer:

Step-by-step explanation: Convert fraction (ratio) 35 / 25 Answer: 140%

The number 35 is 140% of the given number 25.

A fraction or proportion expressed as a percentage of 100 is called a percentage. "%" is used to represent it. Frequently, percentages are employed to indicate relative values, compare amounts, and represent components of a total.

To find out what percent 35 is of 25, we can use the following formula:

Percent = (Part / Whole) * 100

Identify the part and the whole. In this case, 35 is the part and 25 is the whole.

Substitute the values into the formula:

Percent = (35 / 25) x 100

Simplify the expression inside the parentheses:

Percent = 1.4 x 100

Multiply the simplified expression by 100:

Percent = 140

Therefore, 35 is 140% of 25.

In order to find how many students stay back for Chess Club, we want to find 12% of 800.

To do this, we can set up a percentage proportion.

[tex]\frac{12}{100} = \frac{x}{800}[/tex]

We can now solve for x by cross multiplying.

[tex]800 \cdot 12 = 9600\\9600 \div 100 = 96[/tex]

So, 96 students attend Chess Club on Wednesdays.
