Answer:

reflected across the y axis, the point (1, 1) becomes (-1, 1).

Step-by-step explanation:

To reflect a point across the y-axis, all you need to do is negate the x coordinate.  That gives you (-1, 1)

Answer:

rs 200

Step-by-step explanation:

Let cost price = x

At 30% profit; marked price of radio is 30% of x = (100% + 30%) = 130%x

Discount = rs 3%

Profit made = 30

Hence,

Marked price - discount = cost price + 30

130%x - 30 = x + 30

1.3x - 30 = x + 30

1.3x - x = 30 + 30

0.3x = 60

Divide both sides by 0.3

0.3x / 0.3 = 60/ 0.3

x =

1.3x / 1.3 = 60 / 1.3

x = 200

Hence, cost price = rs 200

Answer:

4) b^10

5) 15x^11y^6

6) 8y^5x + 3x

Step-by-step explanation:

b^6 + b^4 = b^10 because this is multiplication. So you have to add the degrees

(3x^3y^5)(5x^8y^1) = 15x^11y^6. This is because

3 *5 = 15.

x^3 +x^8 = x^11

y^5 + y^1 = y^6.  

You have to add the degrees since this is also multiplication.

(2y^2)(4xy^3) + 3x = 24y^5x^2. This is because

2 * 4 = 8

y^2 + y^3 = y^5

x + 0 = x

Therfore, it is (8y^5x) + 3x as the final answer.

Answer:

area of circle in terms of π is [tex]\mathbf{Area=6.25\:\pi }[/tex]

Step-by-step explanation:

The endpoints of a diameter of a circle are A(3,2) and B(6,6). Find the area of the circle in terms of π.

The formula used to find area of circle is: [tex]Area = \pi r^2[/tex]

We need to find radius of circle. For finding radius we will first find diameter of circle using distance formula.

Finding distance between points A(3,2) and B(6,6) using distance formula.

[tex]Distance\:Formula=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

We have [tex]x_1=3, y_1=2, x_2=6, y_2=6[/tex]

Putting values and finding distance

[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Distance=\sqrt{(6-3)^2+(6-2)^2}\\Distance=\sqrt{(3)^2+(4)^2}\\Distance=\sqrt{9+16}\\Distance=\sqrt{25}\\Distance=5[/tex]

So, distance is 5, we can say that diameter of circle = 5

The formula used to find area of circle is: [tex]Area = \pi r^2[/tex]

We need radius, so we know that r = d/2 so, radius = 5/2 = 2.5

Now finding area in terms of π

[tex]Area = \pi r^2\\Area=(2.5)^2\pi \\Area=6.25\:\pi[/tex]

So, area of circle in terms of π is [tex]\mathbf{Area=6.25\:\pi }[/tex]

Answer: I just answered.

Step-by-step explanation:

Answer:

1) ∠A=84°

2) ∠C=20°

Step-by-step explanation:

1)

First, find ∠C:

(I'm assuming the exterior angle of 126° makes a straight line with ∠C)

The angles on a straight line always add up to 180. Therefore:

∠C+126=180

∠C=180-126

∠C=54

Then find ∠B:

We also know that all the angles in a triangle add up to 180. Therefore:

∠A+∠B+∠C=180

∠A+∠B+54=180

∠A+∠B=126

(we know ∠A=2(∠B))

2(∠B)+∠B=126

3(∠B)=126

∠B=42

Now, find ∠A:

∠A=2(∠B)

∠A=2(42)

∠A=84°

2)

First, find ∠B:

(Again, I'm assuming the exterior angle of 100° makes a straight line with ∠B)

The angles on a straight line always add up to 180. Therefore:

∠B+100=180

∠B=180-100

∠B=80

Then find ∠A:

We also know that all the angles in a triangle add up to 180. Therefore:

∠A+∠B+∠C=180

∠A+80+∠C=180

∠A+∠C=100

(we know ∠A=4(∠C))

4(∠C)+∠C=100

5(∠C)=100

∠C=20°

Answer:

Step-by-step explanation:

£480 can be divided into ratio 2 : 6 as 120 and 360 respectively.

Ratio is a quantitative relation between two amounts showing the number of times one value contains or is contained within the other.

Given is to share £480 in the ratio 2 : 6.

We can write -

2x + 6x = 480

8x = 480

x = 60

Now -

The divide can be done as -

(2 x 60) and (6 x 60)

120 and 360

Therefore, £480 can be divided into ratio 2 : 6 as 120 and 360 respectively.

Answer:

LG=8, BG=14

Step-by-step explanation:

The theorem referred to here is:  If a line is parallel to one side of a triangle and intersects the other two sides, it divides those two sides proportionally.

So: using that fact, we can set up a proportion:

12/21 = 2x+2/5x-1

Cross multiply that proportion:

21(2x+2)=12(5x-1)

42x+42=60x-12

54=18x

3=x

Substitute 3 in for x.

LB= 2(3)+2

LB=8

BG= 5(3)-1

BG=14

Step-by-step explanation:each friend get 5 because if he has 47 keeps 2 and has 5 friend 45 divided 5 equals 9

Each friends receive 9 marbles.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into same number of parts.

Given that the Julio has 47 marbles. And he keeps his two favorite marbles.

To share the marbles, she has;

= 47-2

= 45

Then she equally shares the remaining with five friends.

Marbles for each friends = remaining marbles / number of friends.

Marbles for each friends = 45 / 5.

Marbles for each friends = 9

Therefore, each friend receive 9 marbles.

Answer: 624

Step by Step Explanation: Subtract 422 with 76, add 135, subtract 45, add 110, and lastly add 58.

Subtract 422 with 76, 422-76=366.

Add 366 with 135, answer will be 501.

Subtract 501 with 45 since she paid $45. 501-45=456.

Add 456 with 110 and that would be 566.

For the last step add 58 to find the answer and you would get 624.

Final Result: 624.
